The study is aimed to assess the possible benefit of non-positive pressure mechanical support in front of conventional ventilation in patients admitted to the intensive care unit (ICU) because of pure hypoxemic respiratory failure.

Condition Intervention Phase
Acute Respiratory Failure Procedure: non positive pressure mechanical ventilatory support Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Primary Outcome Measures:
  • mortality rates [ Time Frame: patient hospital discharge ]

Secondary Outcome Measures:
  • oxygenation improve [ Time Frame: patient hospital discharge ]
  • diminishing of tracheal intubation incidence [ Time Frame: patient hospital discharge ]
  • ICU and Post ICU hospital length of stay [ Time Frame: patient hospital discharge ]

Enrollment: 64
Study Start Date: June 2001
Study Completion Date: June 2007
Primary Completion Date: June 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: non invasive ventilation approach
pure hypoxemic patients admitted to ICU treated by non-positive pressure mechanical ventilation
Procedure: non positive pressure mechanical ventilatory support
No Intervention: conventionally ventilated
pure hypoxemic patients treated by conventional ventilatory support

Detailed Description:
Pure hypoxemic patients admitted to intensive care unit in a teaching hospital have been randomized to be treated by conventional ventilatory support or non-positive mechanical ventilation support. Those patients who did not benefit from the experimental non-positive ventilatory support, were intubated and conventionally mechanically ventilated and discarded for analysis. The primary outcome was mortality rate in both groups, and secondary outcomes were length of stay, improvement of oxygenation, and reduced complications rates.
