About

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.

Full description

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.

25 participants in 2 patient groups

Begin with BVGA

Active Comparator group

Description:

The volunteers will be asked to breathe 5 minutes of room air through the BVGA, followed by, 5 minutes 100% oxygen, and 5 minutes room air again. This will be followed by 5 minutes room air breathing without the BVGA. Then the same volunteers will be asked to repeat the protocol with the face mask.

Treatment:

Device: BVGA

Device: Face Mask

Begin with Face-mask

Active Comparator group

Description:

The volunteers will be asked to breathe 5 minutes of room air through the face mask, followed by, 5 minutes 100% oxygen, and 5 minutes room air again. This will be followed by 5 minutes room air breathing without the face mask. Then the same volunteers will be asked to repeat the protocol with the BVGA.
