Developing a device to add in a manual ventilation circuit to measure the volume of air administered to the patient as well as provide real-time feedback to the care provider.

Project Overview

Manual ventilation with a bag valve mask can be a life-saving procedure for a patient with respiratory failure. This is often performed by emergency medical services health care workers. An airway device, a tubing that is inserted into the airway, is used in conjunction with the bag valve mask when a patient is being ventilated. There are multiple types of commonly used airway devices, and their relative efficacy is still unknown. In order to identify the most effective airway device, a research study will be conducted to compare the outcomes of those ventilated with different airway devices. Because ventilation via bag valve mask is manually controlled, there is significant variability in ventilation rate and volume between providers. Therefore, a single-use, inexpensive air flow sensor must be designed to ensure only the outcomes of similarly ventilated patients are compared. The air flow sensor will be placed in-line with the ventilatory and airway device, and record air flow, ventilation volume, and rate of ventilation.
