NCT05702411

Brief Summary

A cross-over randomized clinical trial carried out at the Intensive Care Unit. Patients who are on mechanical ventilation for more than 24 hours will be included in the study. The following techniques will be applied: aspiration in a closed system with an expiratory pause of 10 seconds associated to hyperinflation maneuver with a mechanical ventilator with the Air Stacking technique and aspiration technique in a closed system of aspiration with an expiratory pause of 10 seconds.

Outcome Measures

Primary Outcomes (1)

  • Tidal Volume (VT) (ml)

    The tidal volume will be visualized directly at mechanical ventilation monitor. Variations in tidal volume will be considered before and after the interventions.

    At 30-minute after the application of the studied technique.

Secondary Outcomes (13)

  • Weight of secretion aspirated (grams)

    Immediately after the application of one of the protocols.

  • Peripheral arterial oxygen saturation (SpO2) (%)

    1, 10 and 30-minute after the application of the studied technique.

  • Peak inspiratory pressure (PIP) (cm H2O)

    1, 10 and 30-minute after the application of the studied technique.

  • End expiratory pressure (PEEP) (cmH2O)

    1, 10 and 30-minute after the application of the studied technique.

  • Air trapping (AUTO-PEEP) (cmH2O)

    1, 10 and 30-minute after the application of the studied technique.
