title: A model for predicting ventilation rates in mammals.
abstract: The relationship between ventilation rate (1/min) and body weight (kg) in mammals was examined using regression techniques. The initial hypothesis of a single power function relationship was rejected. An additional model of the log-log relationship was developed which is piece-wise linear. Results showed the piece-wise linear model gave a better overall fit to the data suggesting a complex relationship with body weight. The breakpoint in the function occurred at approximately 5 kg. Nonlinear regression of untransformed data gave a better fit than linear regression of the log-transformed data.
