The ‘Permox’ oxygen concentrator

Clinical experience with the oxygen concentrator.

The oxygen concentrator is an accepted means of delivery of long term domiciliary oxygen treatment. Conditions of use, however, need to be carefully defined. Fourteen concentrators were used for one year by patients with hypoxaemic chronic obstructive airways disease, and mechanical reliability, patient compliance with a regimen of 15 hours' use a day, smoking habits, and variation in arterial ...

Use of the Haloxair apparatus with an oxygen concentrator.

Compliance with long-term oxygen therapy by concentrator.

Controlled oxygen therapy has been developed to treat chronic respiratory failure in patients with hypoxic obstructive airways disease (COAD). In two studies published in the early 1980's long term oxygen therapy (LTOT) improved survival and reduced clinical deterioration over a three year period in such patients (1, 2]. The reduction in mortality was proportionate to the number of hours per da...

Use of jet mixing devices with an oxygen concentrator.

Jet mixing devices ("Venturi" devices) can be used in conjunction with domiciliary oxygen concentrators and provide delivered oxygen concentrations similar to those obtained with medical oxygen, though with the devices delivering higher concentrations (above 30% oxygen) the total flow is substantially reduced. A jet mixing device driven by a domiciliary concentrator would be valuable in various...
