Effects of high and low pressure on the human body.

AI Thread Summary
High and low pressure significantly affect the human body, with exposure to very high pressure potentially leading to conditions like nitrogen narcosis and decompression sickness. Conversely, low pressure can result in hypoxia and other physiological challenges. Reliable sources for research include NASA for low-pressure effects and NOAA for high-pressure impacts, as they provide credible scientific information. Quotable sources should include author names and references to original research to ensure credibility. Properly sourced information is crucial for academic assignments on this topic.

Homework Statement


I was asked by my lab teacher to investigate the effects on the human body of being exposed to very high and very low pressures, and while I have found some good sources of info it is not that easy to find good and quotable sources, I was wondering if anyone could offer some help on that matter.

Thanks in advance for all your help.

What is your criteria for a quotable source?
 
The criteria's not too strict, I just don't see any teacher taking seriously info quoted from wikipedia or yahoo answers. The sources are alright as long as they at least state the authors name, and would be even better if they in turn stated their sources.
 
Do research on NASA's websites for low-pressure/vacuum.

NOAA for high pressure.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
