Portable resuscitators failed under hyperbaric conditions. The Pneupac and Motivus devices provided insufficient tidal volume at 2 ATA, while the Stephenson Minuteman offered inadequate ventilatory frequency.

Area of Science:

Hyperbaric medicine
Respiratory support devices

Background:

Portable resuscitators are crucial for emergency respiratory support.
Assessing device performance under hyperbaric conditions is vital for safety.

Purpose of the Study:

To evaluate the functional capacity of three portable resuscitators under hyperbaric conditions.
To determine the adequacy of tidal volume and ventilatory frequency at increased atmospheric pressure.

Main Methods:

Testing of the Pneupac Ventilator/Resuscitator, Motivus Resuscitator (Type P.V.), and Stephenson Minuteman Resuscitator.
Assessment conducted under hyperbaric conditions, specifically at 2 atmospheres absolute (ATA).

Main Results:

The Pneupac and Motivus resuscitators delivered inadequate tidal volumes at 2 ATA.

Related Experiment Videos

The Stephenson Minuteman maintained a constant tidal volume but exhibited an increasingly inadequate ventilatory frequency.

Conclusions:

Standard portable resuscitators may not function reliably in hyperbaric environments.
Further research is needed to develop or identify resuscitators suitable for hyperbaric use.
