Experience of using an adapted snorkel mask as personal protective equipment in the COVID-19 pandemic

Introduction: During the COVID-19 pandemic and the cases of shortages of personal protective equipment (PPE), the utilization of modified snorkel masks has been documented, seeking to provide respiratory and facial pro-tection against SARS-CoV-2 aerosols. However, there is no report of changes in vital signs that can occur with its use, along with the perception of its wear by health personnel. Method(s): A case series was performed. Equipment: Snorkel mask, 3D adapter, and antimicrobial filter. CO2 level, respiratory rate, oximetry, pulse, and blood pressure were monitored for one hour. During the time of use, activities related to patient care were simulated. At the end, the usage characteristics were evaluated through a survey. Result(s): 14 volunteers were included in the study. After one hour of conti-nuous use, the clinical parameters were predominantly normal. 85% of the participants preferred this modified snorkel mask instead of personal protective equipment established for COVID-19 (goggles, N95 mask and visor). Conclusion(s): The adapted snorkel mask could be an alternative to PPE equipment in situations of scarce resources. This is only considered within the framework of its acceptability by a group of health professionals, in addition to the few effects on the vital signs evaluated in this case series. Further objective evaluations of usability and effectiveness are required. Copyright © 2023 Universidad de Antioquia.
