Brief Summary:
The purpose of this study is to evaluate the effectiveness of continuous positive airway pressure ventilation when applied by paramedics to individuals with severe breathing difficulties in the prehospital setting.

Condition or disease Intervention/treatment Phase
Respiratory Insufficiency Hypoxia Device: Continuous positive airway pressure ventilation mask Not Applicable

Detailed Description:
Continuous positive airway pressure ventilation (CPAP) has been shown to be effective in avoiding endotracheal intubation (ETI) for patients with acute respiratory failure in hospital but despite several case series, the effectiveness of the prehospital application of CPAP by paramedics has not been studied in a randomized fashion. We performed a prospective, randomized, non blinded trial to determine whether patients in acute respiratory failure treated with CPAP in the prehospital setting had lower overall ETI rates than those treated with standard care.

Study Type : Interventional  (Clinical Trial)
Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Prehospital CPAP Versus Usual Care for Acute Respiratory Failure: a Randomized Controlled Trial

Primary Outcome Measures :
  1. proportion of patients in each group endotracheally intubated prior to hospital discharge or death

Secondary Outcome Measures :
  1. mortality
  2. critical care unit length of stay
  3. hospital length of stay
