Do you remember the episode of “Dr House” when extraordinary doctor – the hero of the series goes by a plane and one of the passengers on the board loses consciousness, gets into a sweat and goes into convulsions? House was to do his surgery in the air when it suddenly turned out that it was unnecessary because the patient did not keep safety rules that should be observed by all divers and came down with decompression sickness.
The difference in pressure under water and in the air at a height of about five thousand metres is huge. Anyone who flew the plane or dived knows the feeling when the ears “clog up”. It is a sign that the pressure changes rapidly. It is quite uncomfortable but not dangerous if in a simple way we will achieve an equal level of pressure in the ears, for example, by swelling with a blocked nose.
Diving after a flight
There are no contraindications for diving after landing on the ground. The only obstacle may be fatigue caused by journey. Let us remember that diving should take place only in good physical and mental condition.
A flight after diving
Here the problems begins. Immediately after diving an air travel is highly inadvisable. You have to wait. How long? It depends on the quality and frequency of dives. After one dive without decompression you must wait at least 12 hours. This time is extended to 18 hours if more of these dives took place. In the case of decompression dive we should not get on a plane during 24 hours, but if we did a deep decompression dive – up to 48 hours.
