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 twill have two avenues of entry into the body. 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 will increase patient oxygen concentrations to 100%. Completely seals to the faces of infants, children and adults. Includes 1 pair of vinyl exam gloves. Contains detailed instructions. CPR mask with optional oxygen port. Hard case with wrist strap. Latex free.
