Name: XL3: RESPIRATION LAB Please complete the following worksheet questions ( 1 - 5) and submit on the Canvas site as will be instructed (6 points total). Q1. Name the instrument used to measure lung volumes Spirometer (0.5 point) Q2. The following data shows approx. 15 quiet breathing cycles followed by a vital capacity maneuver, carried out by a male subject at rest. Inhalation is plotted in the upward direction (1.5 points) lungs are maximally inflated 2000 }~ “channel 1imi) \folvre. o 3 8 -1000 20 o From these data determine the breathing rate (breaths/ min) calculated breathing rate = 8 breaths/20sec * 3 = 24 breaths/minute Is the value within the normal breathing range? circle Y 7N justify your answer Mark on the trace (spirogram) where the lungs are maximally inflated /. cont Q3. Table 1 shows analysis of 10 breathing cycles from data in Q2. Use these data to answer the following questions (1.5 points) ACTIVE PASIVE Table 1 Breathing Cycle # Tidal Volume (mL) Inhalation Time (s) Exhalatation Time (s) 4 533.34 1,02 4.27 2 566.39 0.86 1.38 3 593.72 0.94 1.24 4 651.57 0.91 : 1.38 5 604.53 0.94 1.63 6 573.38 0.88 1.22 7 499,01 0.96 1.47 8 645.85 0.97 1.27 9 473.26 0.92 1.64 10 462.81 0.95 1.53 Mean 560.386 0.932 1.403 Using the respiration rate you calculated in Q2, use the above data to determine minute ventilation ie how much air moves in and out of the lungs each minute Minute ventilation = VE = TV x f TV -tidal volume = 560.386 f- respiratory rate = 24 VE = 560.386 * 24 = 13,449mL/min or 13.45L/min Minute ventilation = 13.45 Liters/min Explain the physiological basis for differences in the mean inhalation vs mean exhalation time in Table 1 / cont Q4. The following Table shows data for 10 breathing cycles for the same subject as in Q2, after a vigorous workout on an exercise bike.
