Glossary of Portable Oxygen Concentrator Terms

Portable Oxygen Concentrator Glossary Of Terms

Portable oxygen concentrator (or POC):  A small, lightweight medical device that delivers oxygen to patients at higher concentrations than the levels of ambient air. It is very similar to a home oxygen concentrator, but is smaller in size, lighter weight and more mobile. The portable oxygen concentrator makes it easy for patients to travel freely; they are small enough to fit in a car and most of the major portable concentrators are now FAA-approved. These devices also allow you to switch from AC power at home, to DC power in your vehicle, to the unit's own internal battery for true freedom and portability.

POC:  (acronym) Portable Oxygen Concentrator

Oxygen therapy:   A medically prescribed system of providing supplemental oxygen to the body. It is prescribed when diseased lungs are not able to meet the body’s oxygen needs.


Oxygen delivery modes of Portable Oxygen Concentrators

  •   Pulse mode:  When a portable oxygen concentrator is in Pulse mode, the machine will detect when the user begins to take a breath and then deliver a pulsed volume of oxygen determined by the setting number, during inhalation.
  •   Continuous Flow mode:  In Continuous Flow mode, a constant flow or steady stream of oxygen is supplied based on the setting number (in Liters Per Minute).

Chronic obstructive pulmonary disease (COPD):  Refers to a group of lung diseases that block airflow and make breathing difficult.

Emphysema and chronic bronchitis are the two most common conditions that make up COPD. Chronic bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. Emphysema occurs when the air sacs (alveoli) at the end of the smallest air passages (bronchioles) in the lungs are gradually destroyed.

Damage to your lungs from COPD can't be reversed, but treatment can help control symptoms and minimize further damage.  ** (Definition from Mayo Clinic)

FAA Approved:  Approved for in-flight use by the Federal Aviation Administration

Pulse Oximetry: This test measures how much oxygen is in your blood. The test is easy,and the result is a percentage. The doctor will put a sensor on your finger or ear and a light will be used to measure the oxygen content in your blood. The result of this test may show if you need oxygen therapy.

Pulse Oximeter:  Medical device used to measure how much oxygen is in your blood.  Pulse Oximeters can be used by patients at home to help monitor their own blood oxygen levels.  Varieties include:  Fingertip, handheld etc…

Cannula:  Plastic tubing used to supply oxygen through the nose.

LPM:  (acronym) Liters Per Minute.  

Invacare Sensi-Pulse:  The Invacare XPO2 & SOLO2 concentrator features Invacare® Sensi-Pulse™ Technology that customizes the size of each bolus of oxygen to meet patient demand. Whether sleeping, relaxing or exercising, Sensi-Pulse technology adapts to the patient's oxygen needs. 

Sensi-Pulse technology provides constant minute-volume. This means that regardless of a patient's breath rate at any given setting, the same amount of oxygen is provided per minute. As the breath rate decreases, the bolus size increases.

SimplyGo Sleep mode:  Sleep mode is similar to Pulse mode; SimplyGo detects when the user begins to take a breath and then delivers a pulsed volume of oxygen determined by the setting number. The Sleep mode differs from Pulse mode in that it provides increased trigger sensitivity and a softer pulse for exceptional comfort. If no breath is detected for a period of time, the system automatically delivers a continuous flow of oxygen at a rate consistent with the last used Continuous Flow mode setting.

LifeChoice ActivOX Pulse Wave:  With PULSE-WAVE™ Delivery, oxygen is delivered continuously during the first 30% of the inspiratory period so what is delivered by the unit is actually received by the patient. PULSE-WAVE™ Delivery minimizes side effects such as sinus irritations from the retrograde flow.

Airsep UltraSense:  Technology equipped in all Airsep brand POC's which provides a more sensitive pulse dose delivery comparable to other brands that include a “sleep mode” setting. The advanced intelligence built into the microprocessor of the FreeStyle family ensures fast, reliable pulse dose delivery in the first phase of inhalation, when the highest levels of gas exchange are occurring in the lungs. UltraSense technology delivers a reliable pulse dose even when operated with up to 25 ft (7.62 m) of tubing.
