BIOPAC: Volumes and Capacities Cynthia Chiu 23795140 Bio 153 Lab March 3 rd , 2015 A. Volume Measurements Subject Profile Name: Yolanda Lan Height: 150 cm Age: 18 Weight: 51 kg Sex: Female 1. Predicted Vital Capacity Use either equation in Table 3 to calculate the subject’s predicted vital capacity in liters. 2.69 2.69
2. Observed Volumes and Capacities Table 4: Respiratory volume measurements for different types of volume. Type of volume Measurement (liters) Tidal volume (TV) 0.78626 Inspiratory reserve volume (IRV) 1.26258 Expiratory reserve volume (ERV) 1.56008 Vital capacity (VC) 1.87999 Residual volume (RV) used: 1.0 liters (Default is 1.2 liters.) Table 5: Calculated respiratory capacities of inspiratory, expiratory, functional residual, and total lung through the data from Table 4 and the equations from the middle column of Table 5. Capacity Formula Calculation (liters) Inspiratory (IC) IC = TV + IRV 2.04884 Expiratory (EC) EC = TV + ERV 2.34634 Functional residual (FRC) FRC = ERV + RV 2.56008 Total Lung (TLC) TLC = IRV + TV + ERV + RV 4.60892
