Introduction
| • |
Intubated patients are commonly
ventilated using the bag-valve-device (BVD) during air
medical transport, especially for short transports |
| • |
The Oxylator® FR-300 is a small,
hand-held, oxygen-powered device which is pressure-regulated |
| • |
The device delivers a preset peak
airway pressure of 20 cmH2O and maintains a PEEP of 2-4
cmH2O after passive exhalation |
| • |
The size and ease of use of the
device are ideal for use in the prehospital setting |
Objectives
| • |
To compare the effectiveness of
the BVD with the Oxylator among patients being mechanically
ventilated during air medical transport |
| • |
To determine if ventilation and
oxygenation were comparable at baseline, 2 and 5 minutes |
Methods
| • |
Intubated patients being transported
by UMass Memorial Life Flight were randomized to either
the BVD or Oxylator |
| • |
Patients were excluded if they were
less than 18, pregnant, had a known history of asthma,
or had an ET tube less than 7.5 mm |
| • |
A blinded Novametrix Tidal Wave
monitor was used to collect data on end-tidal CO2,
respiratory rate, pulse rate, and oxygen saturation |
| • |
The primary outcome measure was
effectiveness of ventilation (targeted oxygen saturation
> 95% and ETCO2 of 30-45 mmHg) at 5 minutes
with either device |
