RESPIRATORY PHYSIOLOGY 111 v Table 3-1. Respiratory Values for Case 18 Breathing rate 12 breaths/min . Paco, (arterial Pg) 40 mm Hg Pap, (arterial Py.) 100 mm Hg PEo, (Poo, in expired air) 30 mm Hg Plo, (Po, in humidified inspired air) 150 mm Hg Picos (Poos in inspired air) 0 Veo, (rate of CO, production) 200 ml/min Vo, (rate of O, consumption) 250 m/min Poo, Partial pressure of carbon dioxide; P.,, partial pressure of oxygen. QUESTIONS . Using the information provided in Table 3-1 and Figure 3-1, what are the values for tidal volume, inspiratory capacity, expiratory reserve volume, functional resid- ual capacity, vital capacity, and total lung capacity? (Hint: It may be helpful to label the spirometry diagram with the names of the lung volumes and capacities.) . What is the name of the volume remaining in the lungs after maximal expiration that is not measurable by spirometry? What other lung volumes or capacities are not measurable by spirometry? . What is the meaning of the term “physiologic dead space”? What assumptions are made in calculating the physiologic dead space? What is the volume of the physio- logic dead space in this case? . What is the value for minute ventilation? . What is the value for alveolar ventilation? . What is the alveolar ventilation equation? Use this equation to calculate alveolar partial pressure of carbon dioxide (PAgp, ) in this case. . What is the value for alveolar partial pressure of oxygen (PAg,)?
