*** At 4:34-4:35 I accidentally said that tidal volume is .5 mL, which was a slip of the tongue and a mistake on my part. What I meant to say is that the tidal volume is 500 mL, which is equal to .5 liters. Normal Physiologic Changes in Pregnancy: The increased minute ventilation during pregnancy causes a compensated respiratory alkalosis. Inspiratory capacity increases by 15% during the third trimester because of increases in tidal volume and inspiratory reserve volume. The respiratory rate does not change during pregnancy, but the TV is increased which increases the minute ventilation, which is responsible for the respiratory alkalosis in pregnancy. Functional residual capacity is reduced to 80% of the non-pregnant volume by term. These combined lead to subjective shortness of breath during pregnancy.
