Combating COVID-19 during Airway Management: Validation of a Protection Tent for Containing Aerosols and Droplets

Abstract

The COVID-19 pandemic has made it necessary for medical personnel to protect themselves from aerosol-producing procedures, especially during airway management. The tracheal intubation process has a significant risk based on the spreading of aerosol, especially when the medical service provider is very close to the airway of the patient. We have developed a novel conservation tent that provides a barrier for healthcare professionals and patients. Through a simulation study, the relationship between the use of the protection tent during intubation and the contamination of medical personnel before and after the movement of the protection tent was explored. A series of experiments in this article provide a theoretical basis for the verification of spray morphology during gas curing and droplet intubation. This inexpensive and simple method for using transparent cloth in the intubation of patients with unknown COVID-19 status can be applied by frontline medical personnel as an additional precautionary measure.
