MORE ABOUT FLYING AFTER DIVING
In 1990 the Undersea and Hyperbaric Medical Society (UHMS) published a set of guidelines aimed at minimiz-
ing the possibility of decompression sickness due to flying too soon after diving. The UHMS suggests* divers
using standard air cylinders and exhibiting no symptoms of decompression sickness wait 24 hours after their
last dive to fly in aircraft with cabin pressures up to 8,000 feet. (2,440 meters).
The two exceptions to this recommendation are:
• If a diver had less than 2 hours total accumulated dive time in the last 48
hours, then a 12 hour surface interval before flying is recommended.
• Following any dive that required a decompression stop, flying should be
delayed for at least 24 hours, and if possible, for 48 hours.
Since the 1990 UHMS guidelines were introduced, data from the Diver’s Alert Network (DAN) was introduced
that resulted in DAN’s position** that “A minimum surface interval of only 12 hours would be required in
order to be reasonably assured a diver will remain symptom free upon ascent to altitude in a commercial jet
airliner (altitude up to 8,000 ft/2440 m). Divers who plan to make daily, multiple dives for several days, or make
dives that require decompression stops, should take special precautions and wait for an extended surface inter-
val beyond 12 hours before flight”.
