DescriptionOne person can operate the McCulloch Medical™ Aspirator/Resuscitator using an easy push/pull action. Valves at each end do all the work. On the wide end there are two one-way induction valves for aspiration. On the narrow end there is one two-way valve for resuscitation. Aspiration -Attach the aspirator mask on the wide end and place over the muzzle. -One-way induction valves draw air into the unit on the out-stroke. -A vacuum is created when the unit is pumped to remove mucus or fluids that may be blocking the airway. -Tilt head back to open airway. -Four or five pumps will draw the mucus or fluids into the aspirator mask. -Remove the aspirator mask from the pump and follow resuscitation instructions. Resuscitation -Attach the resuscitator mask to the small end of the unit and place over the muzzle. -The one-way valve will induct air into the unit 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 oxygen-depleted air to escape to the side and NOT be reintroduced to the patient. -Resuscitator should be pumped every 5 to 10 seconds to allow full exhalation. -Breathing should be stimulated with as few as 5 to 10 pumps. Check for breathing every few pumps. -If not breathing after 4 to 5 pumps, turn the calf over and repeat. This will allow the lung previously closer to the ground and weighed-down by internal organs to inflate more easily. -Continue while heartbeat remains.
