Question

Mr. Whatsit received the lifesaving valve replacement surgery. Describe the changes you expect to see in his vital signs. Additionally describe the changes you expect to see in both his respiratory and kidney functions.

Answer 1

Increase blood pressure to normal range: normal mitral valve function will maintain normal flow and pressure throughout the chambers

- Increase oxygen saturation: normal blood flow through pulmonary circuit will allow capillary exchange in lungs to conduct at a normal rate

- Decrease respiratory rate: irregular, rapid breathing will not occur because normal oxygen levels will be conveyed to the medulla, signalling the ANS to decreased respiratory rates to normal

- Increased kidney function: normal blood flow through systemic circulation resets kidney function to normal filtration
