A spontaneously breathing patient has a normal PaCO2 of 40 mm Hg, a minute ventilation (VE) of 6 L/min, and a VD/VT ratio of 35% (0.35). Then the patient develops a pulmonary embolus (PE), blocking blood flow to a significant number of ventilated avleoli. Consequently, the measured VD/VT increases to 65% (0.65). 1. Calculate the alveolar ventilation associated with teh original PaCO2 of 40 mm Hg. 2. To maintain the same PaCO2 of 40 after the embolus occurs, what change must occur in total minute ventilation (VE)?
What effect does hyperventilation have on blood pH and why? What simple measure can be used to correct the pH imbalance and how does it work? What effect would hyperventilation have on hemoglobin O2 saturation in a normal healthy individual? What effect would a PaO2 of 60 mmHg have on hemoglobin O2 saturation and why? (explain in terms of the O2-Hb dissociation curve)
Mark's maximal oxygen consumption on an exercise test is 55 ml/kg/min. What MET level did he acheive on his exercise test? Hint: When going from METS to ml/kg/min your multiply by 3.5 ml/kg/min. When going in the opposite direction, ml/kg/min to METS you divide by 3.5 ml/kg/min.

Because CO2 and H+ are linked in a dynamic equilibrium, PCO2 changes will affect both H+ and HCO3- levels. In the scenarios below, use "up" arrow or "down" arrow to indicate changes to PCO2, H+, and HCO3-. If ventilation increases, plasma PCO2 ______________, H+ ______________, and HCO3- ___________________ If ventilation decreased, plasma PCO2 _____________, H+ ______________, and HCO3- __________________
