Conditions

Mechanical ventilation Respiratory Mechanical ventilation

Interventions

A patient was included when readiness to wean criteria were met (see inclusion criteria) A spontaneous breathing trial (SBT) was then performed, in semi-recumbent patients, on a T-pie

Inclusion criteria

Inclusion criteria: 1. Aged 18 years or older 2. Under mechanical ventilation for at least 48 hours 3. Satisfied the weaning criteria. The readiness to wean criteria were: 3.1 The resolution or improvement of the underlying cause of respiratory failure for which the patient was intubated 3.2 Hemodynamic stability, defined as heart rate (HR) 90% with fraction of inspired oxygen (FiO2) =0.4 and positive end expiratory-pressure (PEEP) =8 cmH2O, respiratory rate (RR) =35/min, spontaneous tidal volume (Vt) >5 mL/kg, ratio of RR/Vt 13) 3.5 Adequate cough. 4. Patients also had to have an arterial catheter and a central line with the tip confirmed by x-ray to be in the superior vena cava near at the entrance or in the right atrium.

Exclusion criteria

Exclusion criteria: 1. Tracheotomized patients 2. Do-not-reintubate orders 3. Pregnancy 4. No informed consent 5. Poor cardiac echogenicity

Design outcomes

MeasureTime frame
Weaning failure rate from mechanical ventilation defined as the development of at least one of the following: 1. Respiratory acidosis with pH 45 mmHg 2. Arterial oxygen saturation 0.5 3. RR>35/min 4. Clinical signs of respiratory fatigue
