Pressure equilibration of the middle ear during ascent
human ear barotrauma equalization ascent
2009/7/16
The capacity to equilibrate the middle ear with the ambient pressure depends on different factors. During descent when the clearing is active the technique is the most important factor. During ascent ...
Direct ascent from shallow air saturation exposures
decompression human saturation air venous gas emboli
2009/7/14
Thirty-four healthy human subjects were exposed to shallow air saturation for 48 h [1.77 ATA (25.5 fsw) n = 19, 1.89 ATA (29.5 fsw) n = 15] and then decompressed to 1 ATA (0 fsw) in about 2 min. Sympt...
A case of breath holding and ascent-induced circulatory hypotension
decompression air breath-hold
2009/6/12
We report a case of transient circulatory depression due to inadvertent apnea of a subject during decompression from a stimulated dive. The dive consisted of exposure to air at 5 bar and subsequent de...
Ascent rate, post-dive exercise, and decompression sickness in the rat
decompression exercise Ascent rate animal rat
2009/6/9
The effects of ascent rate and post-dive exercise on the incidence of decompression sickness (DCS) were investigated in six groups of 20 rats exposed for 2 h at a pressure equivalent to 240 feet of se...
Reduction of decompression illness risk in pigs by use of non-linear ascent profiles
decompression helium heliox decompression illness model dry air chamber animal swine
2009/6/9
An established swine model of neurologic decompression illness (DCI) was adapted to investigate the influence of no-stop ascent profile shape on DCI risk after deep air and heliox dives. Pigs underwen...
Direct ascent from air and N2-O2 saturation dives in humans:DCS risk and evidence of a threshold

2009/6/2
To estimate the risk of decompression sickness (DCS) for direct ascents from depth to the sea surface for personnel who are saturated with hyperbaric nitrogen, we analyzed 586 experimental air or nitr...

We all know that diving is a hazardous business, but there is no doubt that the number
of accidents that have been encountered, in particular in the offshore industry, is
far too high. The United Ki...

Significant controversy currently exists regarding Emergency Ascent training. Such
training for sport divers is advocated and arguments in favour of the training not
previously considered are presen...

Before I begin, let me make something perfectly
clear. I am an ichthyologist. For the purposes of this
commentary, that means two things. First, that I have spent
a lot of time underwater. Second, ...
