Question

Need a physiology wiz quick!

Indiana Jones is being chase by villains to escape he grabs a straight bamboo shoot with a base that is 5 cm2 and 1.2 meter long and jumps into a stream. Luckily the stream is just deep enough that the bamboo shoot remains just above the surface. Indiana jones concentrates to slow down his respiratory rate to 10 breaths per minute and increases his tidal volume to 750 mls / breath. Indiana Jones restion VO2 is 220 ml O2/min and his VD is 150 ml. Can Indiana Jones satisfy his oxygen demand while submerge or will he be forced to surface and be caught by his foes?
Justify your answer numerically (fresh air contains 20.94% O2

Explanation / Answer

In this situation, Indiana Jones satisfies his oxygen demand.

Oxygen demand = amount of oxygen inhaled× number of breaths per minute

= 220×10

= 2200 mls

As VD is less than oxygen demand, he satisfies his oxygen demand when submerged.
