About this trial
This is a single-centre prospective observational study aimed to determine if Pocc (occlusion pressure at 100 msec), TCe ( Expiratory time constant ), Mechanical Stress power, Ventilatory ratio and C20/Cdyn would predict outcomes in patients with moderately severe ARDS (Acute respiratory distress syndrome), who are on mechanical ventilation
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients with Acute respiratory failure needing mechanical ventilation
Diagnosis of Severe ARDS with severity: PF ratio < 150, with PEEP/CPAP > 5
Disqualifiers
r2 < 0.95, monitored on the ventilator
Expiratory flow that is not first-order or non-exponential decay
Patients with Nor-epinephrine requirements > 0.1 mcg/kg/min within 2 hours of intubation
Patients requiring ECMO ( Extracorporeal membrane oxygenation)
Trial population
For those patients, who satisfy inclusion and exclusion criteria, Day 1 will be considered as the the day of intubation. Age , gender, Charleston co-morbidity index , SOFA score at the time of intubation. For day 1 to day 3, we shall record average values of Pocc, TCe, C20/C index, Ventilatory ratio, Mechanical stress power , PF ratio will be recorded. Outcome data such as need for vasopressors, prone position, duration of ICU stay, MAKE outcomes, need for paralysis, change in mode of ventilator, ventilator number of days, hospital stay and 30 days outcomes including disability and survival.
