Abstract:
We present the prototype of an adjunct to personal protective equipment (PPE) for intubation of patients with coronavirus disease 2019 (COVID-19). Acknowledging the risk of infection for the airway operator and personnel in the room when tracheal intubation is required for a COVID-19 patient, we designed a chamber that creates a microenvironment around the patient's head that limits the outward flow from a patient's airways to the airway operator with a filtered suction system in order to limit viral spread and lower contamination risk during intubation in non-negative-pressure rooms. The device was successfully tested in a simulation setting.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
