In the first procedure of the lab the pig is hyper ventilated with a manual resuscitator called an Ampu Bag. This is manual positive pressure breathing and in this exercise the rate is very high such that pressure in the thoracic cavity does not have time to return to baseline. The result of this high rate of positive pressure breathing is shown below. Hyperventilate 1. What happened to stroke volume during hyperventilation? (increase, decrease, stayed the same) Stayed the same 2. What happened to blood pressure and why? Include in your answer which determinant of cardiac function initiated this response and why it was changed. 3.You can see there was a slight increase in heart rate when the animal was hyperventilated that returned to normal when the procedure was stopped. Why would heart rate increase?
