Validation of a Novel Handheld Device for Accurate Cricoid Pressure in Healthy Volunteers

"Trained providers will be asked to apply CP at 10N of force to the marked location using the cricoid applicator for one minute. Data relating to applied force across the whole one minute will be measured continuously and will be captured and stored. The CP device will have a microdisc port for internal memory and then the wifi on the board will transfer the information to a cloud server for backup and storage for redundancy.~A threshold of 10 ± 2 N applied force will be set to define successful CP attempts. Participants must remain in this range for 95% of the trial time after the first five seconds have passed.~At any point during the CP application, if the volunteer experiences pain, they can request that the pressure be stopped. However, we do not expect any pain with 10N, except for minor discomfort."
