Study Details

Study Description

Brief Summary

This study will evaluate the correlation between invasively measured parameters (work of breathing/power of breathing, resistance and elastance), derived using esophageal pressure measurements, and their corresponding non-invasive estimated values (noninvasive work of breathing/power of breathing, resistance and elastance), computed using airway pressure and flow measurements only.

Condition or Disease Intervention/Treatment Phase
  • Other: changes in ventilator settings

Detailed Description

This study will evaluate the correlation between invasively measured parameters (work of breathing/power of breathing, resistance and elastance), derived using esophageal pressure measurements, and their corresponding non-invasive estimated values (noninvasive work of breathing/power of breathing, resistance and elastance), computed using airway pressure and flow measurements only. Vent settings will be adjusted to test accuracy over a range of respiratory support conditions.

Arms and Interventions

Arm Intervention/Treatment
Other: Single Observational Group

Patients receiving mechanical ventilation and subject to the intervention: changes in ventilator settings.

Other: changes in ventilator settings
Ventilator settings will be adjusted (vent mode, pressure support/control level, cycling, inspiratory time, mandatory rate).

Outcome Measures

Primary Outcome Measures
