Portable Oxygen Concentrator continuous Flow

A portable oxygen concentrator continuous flow, also known as a POC, functions unlike any standard or liquid oxygen tanks you may currently be using.

Instead of scheduling regular refills or replacements for tanks, a portable oxygen concentrator takes in ambient air and sends it through a filtration process to produce medical-grade quality oxygen.

This innovative process is powered by a rechargeable internal/external battery or both, depending on the oxygen concentrator you choose. They may also be plugged into an AC or DC outlet to power and even charge the unit during treatments.

How does a continuous-flow oxygen concentrator work?

Easily put, an oxygen concentrator pulls in ambient air from its surroundings. The air is then compressed and nitrogen is removed by the air filter and sieve beds to deliver purified medical grade oxygen via a nasal cannula. The level of oxygen delivered is regulated by the flow rate set on your machine.

Whether you are a caregiver or an oxygen patient, you’re here because you want to improve your’s or your loved one’s personal freedom and quality of life.

In this guide to portable oxygen concentrators we will cover everything from their history, why they vary in size, differences in continuous and pulse flow, reasons why you need a POC, traveling tips, purchasing a concentrator, and much more.

Oxygen concentrator vs oxygen tank

To help you make the most informed purchasing decision so you end up with an oxygen concentrator that meets your oxygen and lifestyle needs fully.

Oxygen therapy isn’t something that was newly introduced in the past century, in fact, the molecule of oxygen was discovered all the way back in 1772.

Shortly after oxygen was discovered, the medical implications were quickly realized, specifically for patients suffering from respiratory illnesses.

The use of hyperbaric oxygen chambers to treat COPD or other respiratory illnesses is still widely debated. Typically doctors will not use a hyperbaric oxygen chamber to treat COPD as the increased pressure could cause your lungs to leak into the chest cavity and eventually collapse.

Smallest portable oxygen concentrator

The term “portable oxygen” implies that the medical device is lightweight, durable, easy to use, and most importantly small.

Hubs can be judged by how easily they can be carried on the shoulder. The smaller the hub, the easier it is to carry it under your shoulder without interrupting your walk.

Another important benefit of small portable oxygen concentrators is that they are much easier to store.

If you ever need to store your hub, you can be sure that you will find a place for it.

Plus, since you don’t have to carry small portable oxygen concentrators on the floor, you won’t have to worry about not being able to place it on a table where it can spread germs. The most common sizes are:

Portable oxygen concentrator FAA approved

After patients began to see the incredible benefits that home oxygen concentrators provide, younger and more active patients wanted a method to supplement their active lifestyle on the go.

Cumbersome metal-oxygen or liquid oxygen tanks were the only answer for patients that wanted their oxygen therapy while away from home, however, they severely restricted patients from doing things they enjoyed most, especially traveling.

To help enhance the lives of patients with COPD and other respiratory diseases, manufacturers went to the drawing board to design a portable version of the effective home oxygen concentrator that would be approved by the FAA.

After the development of the Inogen One and the AirSep LifeStyle portable oxygen concentrators, the FAA approved these portable concentrators for in-flight use in 2005.

Paving the way for the portable oxygen concentrators of today and solidifying a new standard for oxygen therapy.

Portable oxygen concentrators with continuous flow

After years of testing and research, manufacturers were able to make incredible strides in the functionality of portable oxygen concentrators.

Today, the battery life of portable oxygen concentrators has been greatly increased and many can be enhanced with the use of an external battery. Many portable concentrators are able to be charged and powered in your car, truck, R.V., or boat through the cigarette lighter outlet.

While many portable concentrators also contain sleep mode technology, which will allow you to use your POC 24/7 such as with a home oxygen concentrator.

  • Portable oxygen machines also feature numerous audible alarms that help keep you safe and let you know when an error has occurred.
  • So you can rest assured knowing that your oxygen concentrator is functioning properly at all times of use.
  • Any concentrator without an alarm system is not FDA or FAA approved.
  • To make operating a portable oxygen concentrator as user-friendly as possible, the entire functionality of the concentrator is controlled by an easy to operate control panel.
  • As technology advances select POC’s are even beginning to feature a touch screen control panel.
Portable Oxygen Concentrator continuous Flow

How does an oxygen concentrator work?

The functionality of an oxygen concentrator may seem like magic at first but in reality, it’s easily explainable. An oxygen concentrator functions by taking ambient air from the surrounding environment. The air is then sent through an internal sieve bed that removes nitrogen and delivers medical grade oxygen to you via a nasal cannula.

A concentrator is operated electrically by its rechargeable internal/external battery, the AC power supply through a standard wall outlet, or in your car, boat, or RV with the DC power supply.

Learn the step by step process of how oxygen concentrators make their own air below.

What does an oxygen concentrator do?

How Oxygen Concentrators Make Their Own Oxygen:

  • Step 1: The concentrator pulls air from its surrounding area
  • Step 2: Air is then compressed and the cooling mechanism protects the unit from overheating
  • Step 3: The Sieve beds and filter remove nitrogen from the air
  • Step 4: Medical grade oxygen is then delivered via a nasal cannula according to your preset flow setting

Battery pack for portable oxygen concentrator

Charging a Portable Oxygen Concentrator

Depending on the portable oxygen concentrator you choose, you may have some or all 3 of the charging methods that will be discussed.

All concentrators can be charged while stationary using an AC power supply through any conventional US or Canadian power outlet. Giving you access to every flow setting while the concentrator is charging.

For charging on the go, the majority of concentrators can at the very minimum be powered through your car battery with a DC power supply, while others will be powered and charged on every flow setting.

When you have more than one battery it can become cumbersome to charge each one individually with the AC power supply. To help, certain oxygen concentrator manufacturers rolled out an external battery charger option. Which operates with its own AC power supply and will charge a battery externally from the concentrator.

How Charging Works:

  • The AC power supply unit cord plugs into the concentrator while the 3 pronged power cord plugs into a wall outlet.
  • The electrical current from the wall outlet will travel through the power supply and begin charging/powering the concentrator’s battery.
  • The oxygen concentrator will begin to charge automatically whether the machine is On or Off.
  • The length of the charging cycle depends on a couple of things:
    • the remaining charge left in the battery,
    • whether or not you are using the POC while charging,
    • the flow rate you use while charging

Continuous flow portable oxygen concentrator

Oxygen Delivery: Pulse Flow vs. Continuous Flow

Pulse flow portable oxygen concentrator

A pulse flow delivery oxygen concentrator is the on-demand delivery method. Rather than providing a continuous stream of oxygen, pulse flow delivery reads and reacts to your breathing rate. At the onset of inhalation, the portable concentrator will recognize your breath and deliver a bolus dose of oxygen.

Since a pulse flow POC only delivers oxygen on-demand, less oxygen is wasted and you get better battery life. With each breath, you will hear the machine makes a faint pulsing sound.

Continuous flow portable oxygen concentrator

As its name implies, a continuous flow portable oxygen concentrator will deliver a constant and continuous flow of oxygen per minute, whether you are inhaling or exhaling.

These POC’s, are for patients that require 0.5 to 3 liters per minute of oxygen. Certain patients can use pulse flow during the day but need a continuous flow at night while sleeping to be used with CPAP/BiPAP or because they breathe too shallowly to trigger the pulse.

A continuous flow is also used by patients who breathe through their mouth rather than their nose. A great way to visualize how continuous flow works is to imagine it as a sink faucet. Once you turn it on to fill your cup a “continuous” stream of water will flow no matter how filled the cup is.

How does an oxygen concentrator work?

An oxygen concentrator receives air, purifies it, and then distributes the newly formed air. Before it goes into the concentrator, the air is made up of 80 percent nitrogen and 20 percent oxygen.

Do oxygen concentrators really work?

Oxygen concentrators are considered sufficiently foolproof to be supplied to individual patients as a prescription item for use in their homes. Typically they are used as an adjunct to CPAP treatment of severe sleep apnea.

What is an oxygen concentrator?

An oxygen concentrator is a type of medical device used for delivering oxygen to individuals with breathing-related disorders.

Individuals whose oxygen concentration in their blood is lower than normal often require an oxygen concentrator to replace that oxygen.

An oxygen concentrator device uses a battery or plugs into an outlet to receive, purify, and distribute air for those who have a low level of oxygen in their blood.

These devices are lighter and less bulky than traditional oxygen tanks. They can lead to a more active lifestyle for those who have additional oxygen needs.

Medical oxygen concentrator

what does an oxygen concentrator do?

Generally, you can’t buy an oxygen concentrator over the counter. A doctor must prescribe it after they’ve completed a thorough medical evaluation. The doctors will also typically show the patients how to effectively use these concentrators while traveling and in their home.

Oxygen concentrators filter surrounding air, compressing it to the required density and then delivering purified medical grade oxygen into a pulse-dose delivery system or continuous stream system to the patient.

These devices are lighter and less bulky than traditional oxygen tanks. They can lead to a more active lifestyle for those who have additional oxygen needs.

How do home oxygen concentrators work?

Home oxygen concentrators are powered through a wall outlet and are intended for stationary therapy.

All these machines are in continuous flow mode and deliver a constant rate of oxygen, regardless of inhalation or exhalation. Home oxygen concentrators can deliver anywhere between 1-10 liters per minute of oxygen, based on your prescription.

As a result, these machines are heavier. They typically weigh between 40-60 lbs, and are often on wheels to easily be moved from one room to another.

When making a purchase, it is important to compare several factors including liter flow, weight, noise, power usage, and altitude.

Oxygen concentrator how it works?

An oxygen concentrator receives air, purifies it, and then distributes the newly formed air. Before it goes into the concentrator, air is made up of 80 percent nitrogen and 20 percent oxygen.

An oxygen concentrator uses that air then it comes out as 90 to 95 percent pure oxygen and 5 to 10 percent nitrogen.

The nitrogen is separated to give the patient the highest dose of oxygen possible, as it is difficult to get that percentage of oxygen without the help of a medical device.

Does an oxygen concentrator produce pure oxygen?

An oxygen concentrator is a medical device that concentrates oxygen from ambient air. This oxygen, compressed and dispensed through a cannula, is 90-95 percent pure.

What are the side effects of being on oxygen?

Oxygen therapy is generally safe, but it can cause side effects. They include a dry or bloody nose, tiredness, and morning headaches.

pulse oximeter

What does a pulse oximeter measure and how does it work?

A pulse oximeter consists of the monitor containing the batteries and display, and the probe that senses the pulse.

The monitor contains the microprocessor and display. The display shows the oxygen saturation, the pulse rate and the waveform detected by the sensor. The monitor is connected to the patient via the probe.

What does a pulse oximeter measure?

What does a pulse oximeter measure and how does it work?

What are the 2 readings on a pulse oximeter?

There are two numerical values obtained from the pulse oximeter monitor:

  • The oxygen saturation of hemoglobin in arterial blood. The value of the oxygen saturation is given together with an audible signal that varies in pitch depending on the oxygen saturation.
    A falling pitch indicates falling oxygen saturation.
    Since the oximeter detects the saturation peripherally on a finger, toe, or ear, the result is recorded as the peripheral oxygen saturation, described as SpO2.
  • The pulse rate in beats per minute averaged over 5 to 20 seconds.
    Some oximeters display a pulse waveform or indicator that illustrates the strength of the pulse is detected.
    This display indicates how well the tissues are perfused. The signal strength falls if the circulation becomes inadequate.
What does a pulse oximeter measure and how does it work?

How does it work pulse oximeter?

During use, the monitor updates its calculations regularly to give an immediate reading of oxygen saturation and pulse rate.

The pulse indicator is continuously displayed to give information about the circulation.

The audible beep changes pitch with the value of oxygen saturation and is an important safety feature. The pitch drops as the saturation falls and rises as it recovers.

This allows you to hear changes in the oxygen saturation immediately, without having to look at the monitor all the time.

The monitor is delicate. It is sensitive to rough handling and excessive heat and can be damaged by spilling fluids on it.

The monitor can be cleaned by gently wiping with a damp cloth. When not in use, it should be connected to an electrical supply to ensure that the battery is fully charged.

Pulse oximeter probe types

The oximeter probe consists of two parts, the light emitting diodes (LEDs) and a light detector (called a photo-detector).

Beams of light are shone through the tissues from one side of the probe to the other. The blood and tissues absorb some of the light emitted by the probe.

The light absorbed by the blood varies with the oxygen saturation of haemoglobin. The photo-detector detects the light transmitted as the blood pulses through the tissues and the microprocessor calculates a value for the oxygen saturation (SpO2).

In order for the pulse oximeter to function, the probe must be placed where a pulse can be detected.

The LEDs must face the light detector in order to detect the light as it passes through the tissues.

The probe emits a red light when the machine is switched on; check that you can see this light to make sure the probe is working properly.

Probes are designed for use on the finger, toe or earlobe. They are of different types. Hinged probes are the most popular, but are easily damaged. Rubber probes are the most robust. The wraparound design may constrict the blood flow through the finger if put on too tightly.

Types of pulse oximeter

Ear probes are lightweight and are useful in children or if the patient is very vasoconstricted. Small probes have been designed for children but an adult hinged probe may be used on the thumb or big toe of a child. For finger or toe probes, the manufacturer marks the correct orientation of the nail bed on the probe.

The oximeter probe is the most delicate part of a pulse oximeter and is easily damaged. Handle the probe carefully and never leave it in a place where it could be dropped on the floor.

The probe connects to the oximeter using a connector with a series of very fine pins that can be easily damaged-see diagram. Always align the connector correctly before attempting to insert it into the monitor.

Never pull the probe from the machine by pulling on the cable; always grasp the connector firmly between finger and thumb.

When not in use, the oximeter probe cable may be loosely coiled for storage or carrying, but should not be coiled too tightly as this will damage the wires inside the cable. The lens and detector should be kept clean. Use soapy water or an alcohol soaked swab to gently clean dust, dirt or blood from the probe.

How to use pulse oximeter correctly?

  • Turn the pulse oximeter on it will go through internal calibration and checks.
  • Select the appropriate probe with particular attention to correct sizing and where it will go (usually a finger, toe, or ear). If used on a finger or toe, make sure the area is clean. Remove any nail varnish.
  • Connect the probe to the pulse oximeter.
  • Position the probe carefully; make sure it fits easily without being too loose or too tight.
  • If possible, avoid the arm being used for blood pressure monitoring as cuff inflation will interrupt the pulse oximeter signal.
  • Allow several seconds for the pulse oximeter to detect the pulse and calculate the oxygen saturation.
  • Look for the displayed pulse indicator that shows that the machine has detected a pulse. Without a pulse signal, any readings are meaningless.
  • Once the unit has detected a good pulse, the oxygen saturation and pulse rate will be displayed.
  • Like all machines, oximeters may occasionally give a false reading-if in doubt, rely on your clinical judgement, rather than the machine.
  • The function of the oximeter probe can be checked by placing it on your own finger.
  • Adjust the volume of the audible pulse beep to a comfortable level for your theatre-never use on silent.

A medical use pulse oximeter

• Always make sure the alarms are on.

If no signal is obtained on the oximeter after the probe has been placed on a finger, check the following:

  • Is the probe working and correctly positioned? Try another location.
  • Does the patient has poor perfusion?
    1. o Check for low cardiac output especially due to hypovolemia, cardiac problems or septic shock. If hypotension is present, the resuscitation of the patient is required immediately. The signal will improve when the clinical condition of the patient improves.
    2. o Check the temperature of the patient. If the patient or the limb is cold, gentle rubbing of the digit or earlobe may restore a signal.

Tip: If you are uncertain that the probe is working properly, check it by testing it on your own finger.

What do the alarms on a pulse oximeter mean?

What do the alarms on a pulse oximeter tell you?

  • Alarms alert the anaesthetist to clinical problems. The alarms are as follows:
    • Low saturation emergency (hypoxia) i.e. SpO2 <90
    • No pulse detected
    • Low pulse rate
    • High pulse rate

Low saturation alarm. The oxygen saturation in healthy patients of any age should be 95% or above. During anaesthesia, the SpO2 should be 95% or above. If SpO2 is 94% or below, the patient must be assessed quickly to identify and treat the cause.

Pulse rate alarms

Pulse rate alarms are useful to let the anaesthetist know that the heart is beating too fast or too slow.

However, alert anaesthetists will have already noticed the abnormal heart rate before the alarms sound.

Children normally have higher heart rates than adults, but the same oxygen saturation-see table below.

AgeNormal Heart RateNormal oxygen saturation (SpO2)
Newborn – 2 years100 – 180SpO2 of 95% or above
2-10 years60 – 140SpO2 of 95% or above
10 years -adult50 – 100SpO2 of 95% or above

measurement instruments

When was the medical thermometer invented?

The first real medical thermometer was invented by Sir Thomas Allbut in 1867. It was six inches long and took about five minutes to take a person’s temperature.

For almost a hundred years thermometers were basically unchanged. They contained alcohol or mercury and were considered to be very accurate. More modern thermometers were developed after World War II that used infrared technology and placed in the ear.

They utilized tiny electrical circuits and numerical readouts that could measure temperature more quickly and with more precision than the liquid-filled glass tubes.

Today modern thermometers use some type of electrical sensors to measure temperature but the same numerical scales developed in the 1700s by Fahrenheit and Celsius are still being used.

If you’re a respiratory patient with a condition such as COPD, pulmonary fibrosis, or cystic fibrosis, you’ve likely accepted change as a normal part of your life.

Being able to implement treatments into your life such as pulmonary rehabilitation, supplemental oxygen therapy, and an improved diet routine is never easy, but it is essential if you want to feel better and improve your long-term prognosis.

But it’s important to remember that COPD treatment rarely remains stagnant. There will likely be a time — whether it’s several weeks, months, or years down the line — when you’ll need to make adjustments to your routine. This could be due to your doctor discovering more information about your condition or it could be caused by a serious event such as a COPD exacerbation.

Either way, you’re going to need to be adaptable in the way that you approach your condition. For example, if your doctor prescribes you 4 hours of supplemental oxygen a day, you might be tempted to get a cheap oxygen device that will simply “get the job done.”

However, since COPD is a progressive disease, it’s safe to assume that you will eventually be prescribed more oxygen use by your doctor. When this happens, you’ll be stuck in a difficult situation where you need to sell your old oxygen device and get a new one that better suits your long-term needs.

What is the smallest portable oxygen concentrator?

The AirSep Focus is an extremely lightweight portable concentrator and doesn’t require refilling it with oxygen.

The mobile unit weighs less than 2 pounds and is currently the lightest and smallest oxygen concentrator out today.

The AirSep Focus is well known for being the smallest and most comfortable to wear portable oxygen concentrator on the market.

How do portable oxygen concentrators work?

You could look at it this way – you can focus on living an active and healthy lifestyle after your oxygen needs are met by such a small and easy to carry portable oxygen concentrator.

Despite its small size, you will find that the Focus has the same excellent battery life as larger portable oxygen concentrators, and is just as dependable and robust, and is a perfect unit for travel, high altitude activities, or hikes.

Battery-powered oxygen concentrator

How many hours do home oxygen concentrators last?

If you have a small portable oxygen concentrator, it should have batteries that continue to give you the kind of freedom you need.

The two micro batteries that come with your AirSep Focus will last for up to 3 hours (1.5 hours for each one). These are powerful lithium-ion batteries that you can recharge with the AC/DC power supply when you are sitting still. To charge them back to 100% from 0% takes around 4 hours total.

If you need more time to be completely mobile, such as when you are doing some long-distance traveling, you can use the supplemental AirSep Airbelt battery pack.

This small battery pack is worn around your waist and can be plugged into the Focus for an added battery life of as much as 3.5 hours.

This comes in handy if you want to travel by air, and your airline requires that you have much more than what your 2 micro batteries can give you.

If you want to spend a day out of the house with friends without having to stop after 3 hours and charge your batteries, the Airbelt is ideal for you.

FAA approved oxygen concentrator

Air travel is already possible with the AirSep Focus because it is approved by the Federal Aviation Administration for use on a passenger airplane.

Just think of how easy it would be to take the Focus with you on a flight, because of how small and light it is. It’s also as quiet as they come, the puffs of air only as audible as a whisper.

The people around you will hardly be aware that you are receiving oxygen therapy, since the carry bag and strap that come with your Focus like other small handbags.
