Impact of ventilator model on mortality: a retrospective cross-sectional study in 147 mechanically ventilated patients with COVID-19 ards
Abstract
SESSION TITLE: Critical Care Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: October 18-21, 2020 PURPOSE: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of a public health crisis that has resulted in the death of thousands within the United States The large influx of patients requiring mechanical ventilation for acute respiratory distress syndrome (ARDS) has necessitated the utilization of ventilators from a variety of sources We hypothesized that ventilator model may be an independent risk factor for mortality in mechanically ventilated patients with COVID-19 METHODS: We retrospectively reviewed the medical records of 147 patients admitted to the adult intensive care unit of a tertiary hospital [New York Presbyterian Queens (NYPQ), Flushing, NY] from 1 March 2020 to 2 April 2020 in whom COVID-19 was confirmed and mechanical ventilation was initiated Patients 30 (Table 1) 87 of 147 patients were dead at 28 days The 28-day mortality rate of mechanically ventilated patients with COVID-19 was 59% As expected, the 28-day mortality rate was higher in patients who were >65 years old (p=0 02) Approximately, half of the patients were ventilated on the PB840, with the remaining divided evenly between the Servo-U and LTV1200 There was no association between ventilator type and 28-day mortality (p=0 73) CONCLUSIONS: To the best of our knowledge, this study is the first to analyze various ventilator models and their relationships…
