Abstract

UNLABELLED: Existing recommendations for mechanical ventilation are based on studies that under-sampled or excluded obese and severely obese individuals.

OBJECTIVE: To determine if driving pressure (DP) and total respiratory system elastance (E

DESIGN SETTING AND PARTICIPANTS: Retrospective observational cohort study during 2016-2018 at two tertiary care academic medical centers using electronic health record data from the first 2 full days of mechanical ventilation. The cohort was stratified by BMI classes to measure median DP, time-weighted mean tidal volume, plateau pressure, and E

SETTING AND PARTICIPANTS: Mechanically ventilated patients in medical and surgical ICUs.

MAIN OUTCOMES AND MEASURES: Primary outcome and effect measures included relative risk of in-hospital mortality, ventilator-free days, ICU length of stay, and hospital length of stay with multivariable adjustment.

RESULTS: The cohort included 3,204 patients with 976 (30.4%) and 382 (11.9%) obese and severely obese patients, respectively. Severe obesity was associated with a DP greater than or equal to 15 cm H

CONCLUSIONS AND RELEVANCE: Despite higher DP and E
