A novel biometric approach to estimating tidal volume.

Background: Low tidal volume ventilation (LTVV) of 4-8 mL/kg of ideal body weight (IBW) reduces mortality in patients with acute respiratory distress syndrome, and, more recently, it has been recommended as the default therapy for all controlled ventilation. However, adherence to LTVV is poor. Barriers to adherence include not having height measurements taken or IBW calculated during admission.
