who was the first to define these units of measurement?
UNANSWERABLE
what happens when a diver gets the bends It forms bubbles inside any part of the body and its effects may vary from joint pain and rashes to paralysis and death. what is the medical term for this condition? Decompression sickness what are some factors that cause it? Underwater diving decompression, caisson, flying in an unpressurised aircraft at high altitude, and extravehicular activity from spacecraft. what exactly happens in the first situation, that results in this condition? During ascent, the ambient pressure is reduced and at some stage the inert gases dissolved in any given tissue will be at a higher concentration than the equilibrium state and when there is a pressure reduction, excess gas may form bubbles, which may lead to this condition. what are the units for measuring the type of pressure mentioned above? kPa is the unit used in fields such as meteorology and underwater diving, in other circumstances the units used to measure is in 'psi' or 'atm'.

Ambient pressure [SEP] Units of pressure
The SI unit of pressure is the pascal (Pa), which is a very small unit relative to atmospheric pressure on Earth, so kilopascals (kPa) are more commonly used in this context. The ambient atmospheric pressure at sea level is not constant: it varies with the weather, but averages around 100 kPa. In fields such as meteorology and underwater diving, it is common to see ambient pressure expressed in bar or millibar. One bar is 100 kPa or approximately ambient pressure at sea level. Ambient pressure may in other circumstances be measured in pounds per square inch (psi) or in standard atmospheres (atm).
