Maximal inspiratory and expiratory airway pressures (P I max and P E max) were measured in 100 healthy infants (51 males, 49 females; age range, 0.06–3.76 years) by occluding the airway with a suitable face mask during a crying effort. Mean values ± SD for P I max and P E max were 118 ± 21 cm H 2 O and 125 ± 35 cm H 2 O, respectively. Maximal inspiratory pressure was independent of age, sex, and anthropometrics, while maximal expiratory pressure showed a low but statistically significant positive correlation with body weight ( P < 0.001).
