NCT01339533

Brief Summary

APRV mode of ventilation will result in an improved partial pressure of arterial oxygenation/ fraction of inspired oxygen (P/F ratio) on day 3 of mechanical ventilation. Sub hypotheses: APRV will be associated with a reduced amount of sedation used during the ICU stay in patients with respiratory failure. APRV will be associated with a reduction in the amount of vasoactive medication used for blood pressure support in patients with respiratory failure.

Outcome Measures

Primary Outcomes (1)

  • P/F Ratio on Day 3 of Mechanical Ventilation

    Our first objective is to measure and compare the partial pressure of oxygen in the artery to the inspired oxygen ratio (P/F ratio) on day 3 of mechanical ventilation. We will also collect and compare common variables used to evaluate lung injury and severity of respiratory failure in both groups. These variables and markers include: the Oxygenation index (OI) and standard blood gas parameters (PH, PaCO2 and PaO2).

    Day 3

Secondary Outcomes (2)

  • Amount/Duration of Sedative & Vasoactive Medication

    Up to ICU discharge

  • Evaluate Feasibility & Clinical Compliance with 2 APRV Paper Protocols.

    Up to ICU discharge

Study Arms (3)

APRV ls

EXPERIMENTAL

APRV low stretch will titrate Plow to maintain release volumes between 4 and 8 cc/kg.

Device: Mechanical Ventilation

AC/VC Conventional Ventilation

ACTIVE COMPARATOR

Standard volume control ventilation with the ARDS Net protocol.

Device: Mechanical Ventilation

APRV h

EXPERIMENTAL

APRV Habashi protocol which sets Plow equal to 0.

Device: Mechanical Ventilation

Interventions

Patients who experience problems breathing and require assistance in breathing are placed on a machine that delivers air to the lungs through a tube through the vocal cords. This study is testing 3 protocols for that machine.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Hypoxemic respiratory failure requiring mechanical ventilation for \>24 hours.

You may not qualify if:

  • Age under 18
  • Severe chronic obstructive lung disease
  • Patients in whom the only indication for mechanical ventilation is airway protection from poor neurological status.
