Question 1
Boyle's law states that at constant temperature the pressure and volume of a gas are inversely related (P1V1 = P2V2). A diver exhales a 6-L lungful at the surface (1 ata). What volume would that same gas occupy if the diver descended to 99 fsw (4 ata) without any further breathing?
Correct Answer:
1.5 L
Question 2
In seawater, what depth corresponds to one atmosphere (1 ata) of gauge pressure?
Correct Answer:
33 fsw / 10 msw
Question 3
Which gas law explains the increased dissolved nitrogen burden in tissues at depth?
Correct Answer:
Henry's law
Question 4
Which gas law underlies the calculation of inspired oxygen partial pressure as depth increases?
Correct Answer:
Dalton's law of partial pressures
Question 5
A patient is breathing 100% oxygen at 3 ata in a hyperbaric chamber. What is the inspired PO2 (approximate, ignoring water vapor)?
Correct Answer:
2280 mmHg
