What Are Portable Oxygen Concentrators

By Mithul Mistry

A portable oxygen concentrator is a mobile device that provides oxygen considerably higher than ambient air to a Chronic Obstructive Pulmonary Disease patient who is active. Fourteen million Americans suffer from various stages of COPD. Oxygen concentrators offer greater mobility for physically active COPD sufferers. The demand for less stigmatizing designs for oxygen concentrators has led to the development of smaller, less cumbersome styling and highly portable powered devices.

Portable oxygen concentrators can be very small like the size of a small camera as in the Free Style by AirSep device which weighs only five pounds and offers 90% oxygen concentration. It is for patients who are very active. It is the lightest most portable oxygen concentrator available. This device is powered by AC and battery. The batteries are rechargeable and have a 3.5 hour recharging cycle. When fully charged the battery life can last up to 4 hours.

Oxygen therapy is no longer delivered in dangerous compressed air tanks which can explode if exposed to a spark or an open flame. Now concentrators allow mobility for users. These devices can be up to 14.85 pounds as in the Oxilife Independence which is 12″ x 8″ x 8″ and has a standard electrical outlet for home. It operates for 3hours at 2 LPM and will flow for 1 hour at 3 LPM.

Many devices are very quiet emitting less than 40 decibels of sound in typical situations. The breathing rate of the user may also create a conflict. Read the rest of this entry »

Besides seeking pain relief, being short of breath is the most common reason patients request to see their doctors. It becomes more prevalent within the age bracket of 55-69, perhaps due to the peaking of certain chronic conditions and diseases that until this point have not exhibited any symptoms.

Pulmonary and cardiac conditions account for 66% of cases of being short of breath. When diagnosing this condition doctors will often refer to it as dyspnoea. It covers many causes and leaves it general enough to be treated multi symptomatically.

Some of the cardiac causes are acute myocardial infarctions, arrhythmia, severe oedema, and pericarditis. These would include heart attacks, severely abnormal heartbeats fast or slow and inflammation of the hearts surrounding sac. Read the rest of this entry »
