Excerpt
The ARDSnet study [
1] demonstrated a 22% relative reduction in mortality using tidal volumes of 6 ml/kg (ARDSnet strategy). Tidal volumes were estimated using predicted body weight, which was calculated using an equation based on the patient’s gender and height. It has been suggested that clinicians are using actual body weight rather than predicted body weight to calculate tidal volume. Actual body weight can be up to 30% higher than predicted body weight, and this may lead to tidal volumes being used that are in excess of those recommended [
