Ventilating a patient using a bag valve and a face mask is not easy to perform, especially for a long period of time, and mandates experience and strength by the care giver. The need for a tight seal around the mouth and nose is a major challenge especially if the patient has a beard. Nevertheless, the face mask is the only approved respiratory support that medics and other basic care givers are allowed to use in the out-of-the-hospital setting, and only physicians and paramedics are allowed to use more advanced techniques, providing a definite airways. Thus, despite its lower effectiveness, the bag valve mask technique is the most commonly used in the field~The purpose of this study is to evaluate the efficacy of a novel bag valve guedel adaptor (BVGA) that enables the direct connection of a bag valve device to a guedel - eliminating the need for a face mask.~Study Design: Prospective, randomized, controlled. The volunteers will be asked randomly assigned to breathe through the BVGA/Face mask followed by the same protocol with the Face-mask/BVGA: 5 minutes room air, 5 minutes 100% oxygen, and 5 minutes room air again. The BVGAs/face masks well be connected to a standard operating room ventilation machines, and cardiopulmonary parameters will be monitored and documented.
Ventilation of a bearded patient with the commonly used face mask has low efficiency because of difficulties to achieve a tight seal around the mouth and nose.~The purpose of this study is to evaluate the efficacy of a novel bag valve guedel adaptor (BVGA) that enables the direct connection of a bag valve device to a guedel - eliminating the need for a face mask.
