In our hospital we've been treating patients with leg ulcers using topical hyperbaric oxygen chambers for many years now. Until now we've been using chambers with constant pressure. We're developing new chambers now. In the published articles from this field the researchers were using chambers where the pressure cycled from 5 to 50 mbar.
Does anyone know for how long the wound is exposed to 50 mbar and than to 5 mbar?

Hubert,
That is a great question. There are chambers here in the US that I use that automatically adjusts the compression rate throughout the compression phase of a treatment cycle - the first one-third of the compression phase. The slower compression rate allows the patient to accommodate for initial changes in inner-ear pressure gradually. The chamber then smoothly ramps up the rate to reach the desired Pressure Set. This method allows for maximum patient saturation exposure without exposure to possibly discomforting compression rates. Once the desired pressure set is reached I have not heard of anybody adjusting that until the treatment time is reached.
