Safety and Efficacy of a Novel Facemask for Positive Pressure Ventilation
A study testing Waters Mask and Standard Mask in people with Anesthesia Induction Ventilation, run by Medical University of South Carolina at 1 site in United States.
Trial summary
Positive pressure ventilation can be life saving for patients who are hypoxic, hypercapneic or apneic. Manual ventilation with a facemask is a skill that is routinely required for emergency medical technicians, respiratory therapists, nurses and physicians. Read more about this study

About this study
Positive pressure ventilation can be life saving for patients who are hypoxic, hypercapneic or apneic. Manual ventilation with a facemask is a skill that is routinely required for emergency medical technicians, respiratory therapists, nurses and physicians. Although mask ventilation skills are routinely taught, even the most skilled and experienced anesthesiologists struggle to effectively mask-ventilate.
The effective use of a standard mask requires the simultaneous establishment of a seal between the mask and face and the lifting of the jaw. The preferred grip is referred to as the C\&E technique. The C\&E technique requires the index finger and thumb to form a "C" and push down on the mask to establish a seal between the mask and face. The lateral three fingers form the "E" and wrap under the jaw to provide lift. The grip required to establish the seal and jaw lift simultaneously is awkward and difficult to teach. The basic design of the standard facemask has not changed in approximately 100 years.
This study will evaluate a new mask design, Warters Mask, is based on a novel design that allows a far more ergonomic grip. The C\&E technique is replaced by a more natural grip. With the Warters Mask, downward pressure with the palm of the hand centered on the mask provides the seal between the face and the mask. The other four fingers align under the jaw to provide lift.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Waters MaskDevice
All anesthesiologists and CRNAs will view an instructional video on the use of the Warters Mask. Following induction of general anesthesia with the standard of care sequence of medications, each patient will then have mask ventilation performed and graded (Han and Warters Scales).
Standard MaskOther
Following induction of general anesthesia with the standard of care sequence of medications, each patient will then have mask ventilation performed and graded (Han and Warters Scales). Mask ventilation will be scored with both masks before and after the standard administration of paralytic medication.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Manual ventilation with a facemask is a skill that is routinely required for emergency medical technicians, respiratory therapists, nurses and physicians. Although mask ventilation skills are routinely taught, even the most skilled and experienced anesthesiologists struggle to effectively mask-ventilate.

The lateral three fingers form the "E" and wrap under the jaw to provide lift. The grip required to establish the seal and jaw lift simultaneously is awkward and difficult to teach. The basic design of the standard facemask has not changed in approximately 100 years.
