One person can operate the McCulloch Medical Respirator/Aspirator using a simple push-pull action. Valves at each end do all the work. On the wide end there are two, one-way induction valves. On the narrow end there is one, two-way valve.
Aspiration
- Attach the aspirator mask on the wide end and place over the muzzle
- One-way induction valves draw air in on the out stroke
- A vacuum is created when the device is pumped to remove any mucus or
fluids that may by blocking the airway - Four or five pumps will draw the mucus or fluids into the aspirator mask
- Remove the aspirator mask from the pump and begin resuscitation steps
Resuscitation
- Attach the resuscitation mask to the small end of the device and place over the muzzle
- The one-way valve will induct air into the device on the out stroke and drive
it down through the two-way valve into the lungs on the in-stroke - The two-way valve then opens and allows carbon dioxide to escape to the
side as to NOT reintroduce oxygen-depleted air - Life-saving oxygen is delivered to the lungs at a constant tidal volume
- Resuscitator should be pumped every 5 to 10 seconds
- Breathing should be stimulated with as few as 5 to 10 pumps
