(Show your work) - Heart rate (ECG) Ventilation rate dal volume) 6 Time (seconds) 06.2 (3pt) Calculate the ventilation rate (in breaths per minute) from the simplified tidal volumes in the graph above (Show your work) Q7. 16pt] Paul has leukemia and needs a bone marrow transplant, a procedure that infuses healthy blood-forming and nucleated stem cells into the body. Paul has type AB blood. Although his cousin, Jen, is willing to help, she cannot provide Paul with her bone marrow cells. Jen has type A blood.
