What is the RER of an individual with an oxygen consumption of 220 ml/min and a carbon dioxide production of 182.6 ml/min? Report your answer to 2 decimal points. QUESTION 29 What percent of the individual's oxygen consumption in the previous question is being used to combust carbohydrate for energy? Round your answer to the nearest whole number and answer with a number only as units are given in the question.
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)?

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.
The below graph shows both ventilation and blood lactate concentration as a function of total oxygen consumption during a bout of exercise. Explain the relationship between these two variables and why these two measures (ventilatory threshold and lactate threshold) tend to occur around the same level of exercise intensity.
Under certain circumstances, the respiratory quotient (RQ value) for an athlete exercising intensely can rise above 1. How is this possible?

How is CO2 diffusing out of working muscle transported in the blood (to the lung capillaries)? Choose the two main forms. (pKa of H2CO3: 6.4; pH of blood: 7.4) O H2CO3; CO2 gas O HCO;1: CO2 gas O HCO31; Carbamate (R-NH-Coo, CO, is carried by hemoglobin) O H,CO3; Carbamate (R-NH-COO, CO2 is carried by hemoglobin)
Mechanical ventilation is indicated when the patient's spontaneous ventilation is inadequate to sustain life by hooking the patient into a mechanical ventilator. It provides breathing support until lung function is restored, delivering warm (body temperature 37° C [98.6° F]), 100% humidified oxygen at FiO2 levels between 21% to 100%. 1. Discuss the process how does positive-pressure ventilator deliver air to the lungs? List 3 risks or complications of patient who is hooked in mechanical ventilator and discuss how it is even possible.
