Baseline pulmonary physiologic values for the squirrel monkey (Saimiri sciureus)

Baseline pulmonary physiologic values were determined on 43 (421-910 g) male and 47 (425-604 g) female squirrel monkeys (Saimiri sciureus). Respiratory rate was found to be 55 +/- 1.9 (SE) breaths per minute for males and 58 +/- 1.7 breaths per minute for females. Tidal volume was 8.9 +/- 0.37 ml for males and 7.5 +/- 0.28 ml for females. Airway resistance for the male was 0.052 +/- 0.006 cm H2O/ml/second; while for the female it was 0.086 +/- 0.011 cm H2O/ml/second. Dynamic compliance was found to be 1.78 +/- 0.15 ml/cm H2O for males and 1.48 +/- 0.124 ml/cm H2O for females. An index of distribution of ventilation was 48 +/- 2.5 breaths for males and 42 +/- 1.7 breaths for females.
