Air that is reduced in volume by pressure.
The mixture of gases present in the earth's atmosphere consisting of oxygen, nitrogen, carbon dioxide, and small amounts of other gases.
Decompression external to the body, most often the slow lessening of external pressure on the whole body (especially in caisson workers, deep sea divers, and persons who ascend to great heights) to prevent DECOMPRESSION SICKNESS. It includes also sudden accidental decompression, but not surgical (local) decompression or decompression applied through body openings.
An activity in which the organism plunges into water. It includes scuba and bell diving. Diving as natural behavior of animals goes here, as well as diving in decompression experiments with humans or animals.
A condition occurring as a result of exposure to a rapid fall in ambient pressure. Gases, nitrogen in particular, come out of solution and form bubbles in body fluid and blood. These gas bubbles accumulate in joint spaces and the peripheral circulation impairing tissue oxygenation causing disorientation, severe pain, and potentially death.

Effects of commercial air travel on patients with pulmonary hypertension air travel and pulmonary hypertension. (7/7)

BACKGROUND: Limited data are available on the effects of air travel in patients with pulmonary hypertension (PH), despite their risk of physiologic compromise. We sought to quantify the incidence and severity of hypoxemia experienced by people with PH during commercial air travel. METHODS: We recruited 34 participants for a prospective observational study during which cabin pressure, oxygen saturation (Sp O 2 ), heart rate, and symptoms were documented serially at multiple predefined time points throughout commercial flights. Oxygen desaturation was defined as SpO2, <85%. RESULTS: Median flight duration was 3.6 h (range, 1.0-7.3 h). Mean +/- SD cabin pressure at cruising altitude was equivalent to the pressure 1,968 +/- 371 m (6,456 +/- 1,218 ft) above sea level (ASL)(maximum altitude 5 2,621 m [8,600 ft] ASL). Median change in Sp O 2 from sea level to cruising altitude was 2 4.9% (range, 2.0% to 2 15.8%). Nine subjects (26% [95% CI, 12%-38%]) experienced oxygen desaturation during flight (minimum Sp O 2 5 74%). Thirteen subjects (38%) reported symptoms during flight, of whom five also experienced desaturations. Oxygen desaturation was associated with cabin pressures equivalent to . 1,829 m (6,000 ft) ASL, ambulation, and flight duration(all P values , .05). CONCLUSIONS: Hypoxemia is common among people with PH traveling by air, occurring in one in four people studied. Hypoxemia was associated with lower cabin pressures, ambulation during flight, and longer flight duration. Patients with PH who will be traveling on flights of longer duration or who have a history of oxygen use, including nocturnal use only, should be evaluated for supplemental in-flight oxygen.  (+info)

The severity of decompression sickness can vary widely, ranging from mild discomfort to life-threatening complications. In severe cases, the condition can cause respiratory failure, cardiac arrest, and even death.

The risk of developing decompression sickness increases with the depth and duration of the dive, as well as the speed at which the diver surfaces. To minimize the risk of this condition, divers are advised to follow established diving procedures and protocols, including gradual ascent from depth and regular stops at specific depths to allow for decompression.

Treatment for decompression sickness typically involves hyperbaric oxygen therapy, which involves breathing pure oxygen in a pressurized chamber to help dissolved gases in the body to be absorbed and excreted more quickly. In severe cases, hospitalization may be necessary to monitor and treat complications such as respiratory or cardiac failure.

Prevention is key when it comes to decompression sickness, and divers are advised to take a number of precautions to minimize their risk, including:

1. Planning dives carefully to avoid excessive depth and duration.
2. Following established diving procedures and protocols.
3. Using proper equipment and maintaining it in good condition.
4. Making gradual ascents from depth and regular stops at specific depths to allow for decompression.
5. Avoiding alcohol and sedatives before and after diving.
6. Getting plenty of rest before and after diving.
7. Seeking medical attention if any symptoms of decompression sickness are experienced.
