Thus divers should wait before flying at an altitude 2000 ft 610 mfor. Unfortunately a lower partial pressure of oxygen in the tissues also occurs with the decompression and lower cabin pressure involved in commercial flights.

Symptoms of decompression sickness did worsen however when this altitude was exceeded.
Flying with decompression sickness. What about flying after decompression illness. But it can occur after a dive of any depth. 6142018 Truthfully speaking ascending to a high altitude immediately after diving increases a persons risk of suffering from decompression sickness.

When flying after diving the ascent to altitude increases the risk of decompression sickness DCS because of the additional reduction in atmospheric pressure. Flying or climbing to an altitude greater than 300m should be avoided for 4 to 6 weeks to avoid recurrence of symptoms. According to Divers Alert Network and other organizations the condition can be exacerbated by a person being exposed to a high altitude too soon after scuba diving.
Decompression Sickness also commonly referred to as DCS is a very dangerous condition related to scuba diving. Though modern aircraft are safer and more reliable. The higher the altitude the greater the risk.
Reports of 1159 decompression sickness DCS incidents during recreational diving were analyzed by logistic regression for the effects of flying on the occurrence of Type II DCS complete relief of symptoms after one recompression and residual symptoms 3 months after treatment. 4222013 Decompression Sickness was initially categorized as either Type I less severe or Type II more severe. By scuba diving and flying soon after increase your risk of Decompression Sickness DCS or the bends due to decreased ambient pressure on the plane.
