Descriptions:

Preferred by professionals, yet easy enough
to use for any rescuer, our latex free rescue mask makes resuscitation
safer for the responder and more efficient for the patient. Since you
won’t be pinching the patient’s nose shut, each rescue breath will have
two avenues of entry into the body.

By using this type of mask, rescue breathing is more efficient.
Supplemental oxygen, connected by way of the mask’s oxygen inlet,
increases concentrations of organ-sustaining oxygen by 50%. Remove the
included valve, and the mask can be connected to a BVM. The BVM with
reservoir can increase patient oxygen concentrations to 100
