The Need For Supplemental Oxygen and Portable Oxygen Systems

16th September 2014 by admin Comments Off

For the many thousands of people who depend on supplemental oxygen it is not something they like or something they looked forward to before they were prescribed with additional oxygen. It is however an ever present fact of their lives.

At this stage wishful thinking is worse than useless – it is an excuse not to accept their current health related situation.

Having said that, for a large percentage of people who live with supplemental oxygen, things are much better than they used to be, and perhaps more importantly, than they had imagined. And this is because of new developments in oxygen delivery systems. The developments that relate to design and technical advances, are much more user friendly.

Today a large, in fact a very large, proportion of patients with chronic obstructive pulmonary disease (COPD) lead much more active lives than they could have twenty or even ten years ago. Home oxygen units were the first major change. Prior to that patients lived with what could be termed as a clinical oxygen dependency. Now home oxygen units are able to supply their oxygen needs with out major problems.

There are three types of oxygen delivery systems for patients that need additional oxygen, and these are:

  1. Compressed oxygen tanks -that store oxygen as a gas.
  2. Liquid oxygen tanks – storing liquid oxygen tat is then released as a gas.
  3. Oxygen concentrators – These are not storage containers but machines that extract oxygen from the surrounding area; the concentrated oxygen is then delivered to the patient.

The end result is that living with supplemental oxygen is much easier than previously and this in a sort of reverse “Catch 22″, means that patients have much more positive attitudes with their overall health status; this in turn gives them the motivation for a more active lifestyle; which makes living with additional oxygen easier – and so on with the cycle.

Perhaps the most important advances in oxygen delivery systems is in the portable oxygen area.

These same home delivery systems have their equivalent as portable oxygen machines but with the added advantage of design developments that are reflected in size, weight, oxygen durability, and in the case of portable oxygen concentrators, power durability (with both a plug in option and rechargeable batteries).

The ongoing results – ongoing as new and improved models are still coming out – mean that living with supplemental oxygen, though not something desired by anyone, is today much easier and binging with it much greater mobility.

In other words the range of activities available to patients is so much greater that you can achieve a high quality of life in terms of greater freedom and mobility.

Bronchiectasis Symptoms

1st October 2013 by admin No Comments

Symptoms of bronchiectasis develop gradually and sometimes do not appear for a long period of time. Symptoms of bronchiectasis include chronic cough, large amounts of foul-smelling sputum, hemoptysis, dyspnea, weight loss, fatigue, weakness, clubbing, wheezing and repeated lung infections.

Respironics EverGo Portable Oxygen Concentrator, Features

17th June 2013 by admin 2 Comments

I have highlighted the Respironics Evergo, simply because I have experience with it.  My stepfather has been using one for years.  He has tried various others but this is the one he has chosen because it serves him and he is comfortable with it.  (At 80, it is not the time for too many experiments).

Some of the important things for him include the pulse dose settings, the trolley and the low maintenance. Although he is travelling much less, up till two years ago he did, and this little machine accompanied everywhere. (It still does, but there much less air travel).

An interesting thing is he lives with my mother at an altitude of 9000 + feet, and allthough he must be on supplemental oxygen 24/7, he has no problems with his supply (either home or portable).

I still remember about ten years ago, that it was difficult to adjust in the beginning, but now it has become an ordinar part of his daily (and nightly) routine. So when recommends, I listen.

Anyway, here it is. (Below you will find features etc).

Airsep FreeStyle – Portable Oxygen Brands

20th October 2011 by admin 1 Comment

Anyone who requires supplemental oxygen on a continuous basis know that there are certain practical things their portable oxygen machine should cover.

First of all (and obviously) the oxygen unit should provide oxygen in the required quantities,  at the required flow rate and for longer periods of time.

Secondly, it has to be portable – and this goes for those who lead active life styles as well as those who,  for whatever reason,  are limited in their range of activities.

This means that the portable oxygen concentrator has to be lightweight and easily carried.

This is where the Airsep FreeStyle comes into its own as the lightest POC weighing a little less than 5 lbs (2.3 kg) – which is similar to the smallest oxygen tanks or cylinders but with an unlimited supply of oxygen.

Portable Oxygen Concentrator Models And Their Weights

5th November 2010 by admin No Comments

For people who need supplemental oxygen there are three basic choices – the actual type has to take into account the level of activity and the doctor’s prescription and suggestions. This additional oxygen need is provided by machines. The choices are oxygen cylinders holding liquid oxygen, tanks with compressed oxygen, and finally portable oxygen concentrators, the main focus of this post.

The portable oxygen delivery is the way patients can recover their ability for a more active life as not being able to stay active is one of the most negative psychological effects. Needing an extra supply of oxygen should not mean having to stay put on a bed or a chair while it is being administered.

An oxygen concentrator is a machine, powered by electricity, that extracts oxygen from the surrounding air and delivers it in concentrated form to the patient. What is important is that as long as the power source is working, oxygen delivery is being met.

There are home and stationary concentrators and portable ones. Imagine that you or someone near you has been prescribed with supplemental oxygen. With a portable oxygen cylinder you may have a couple of hours, depending on the flow, of oxygen before the tank empties. This means that if you are in a car, or anywhere else, you have a very specific time frame to get to another oxygen source – probably a stationary and much larger cylinder.
The other scenario, you are out and about, carrying your portable oxygen concentrator. You may have a spare battery or can reach an electric outlet to recharge.

There are many portable oxygen concentrator models in the market and to be portable means that they have to be easy to carry or pull along. Therefore weight is a prime consideration.
