Dr. Paul Thomas, you wrote:
If the chest wall and diaphragm did not move at all, as nature abhors a vaccuum an equal volume of blood from venous return fills the pulmonary capillaries - there will be a net transfer of 4.5 litres of blood from the peripheral circulation into the pulmonary circulation, which the body can cope with
The scope of the blood transfer described above would appear to me to be an event that seldom, or maybe never, is experienced by the human body unless subjected to the relatively extreme pressures encountered in un-natural human environments, such as the one the body is exposed to when diving. Correct?
If this is the case, are there any negative repercussion from repeatedly exposing the body to this type of change? Any reseach on this subject?
Do the physical demands placed on the body in order to be able to cope with this event, place some individuals with certain physical characteristics at greater risk of something going wrong?, aside from asthmatics.
Thank you for your good explanations, once again.
Peter
