Question

Bae just knocked over a jewelry shop, making off with a couple of bars of 24K gold. On the lam from the cops, they run toward a river. Noting a patch with many reeds (hollow-centered plants), they cut a piece of reed approximately 2’ long. With the gold bars in their pockets, they submerge themselves 1&1/2 feet into the river and begin to breathe, confident they will escape the cops. Within seconds, they were captured, and their one phone call is to you for some bail money.

Why were they caught so soon? What changes in arterial blood gases would occur as a result?

Sketch what a davenport curve would look like at the moment of capture, showing what their acid-base status would be? Why?

Answer 1

Question no 1

They called me and when I enquired they said they the stick was 2' in length . So they went down to the water surface but a pressure difference between the atmospheric pressure and the pressure underwater make it unable fir them to breath through the stick . So they will only be able to breath out but not inhale . This results in the retention if co2 which trigger the need for breathing and made them move up to the water surface ,and the police caught them . The condition is respiratory acidosis.

Chages in arterial blood gas was an incredible increase in pco2 and reduction in the amount of O2 in blood . slight increase in bicarbonate value can also be seen with slight reduction in H+ ion value .

Question no 2

Davenport curve

Condition is RESPIRATORY ACIDOSIS

Their acid base status would be acidosis. It is due to lack of inspiration and the increase in pco2 level in blood leading to a reduction in pH . As co2 increase the pH also increase.
