Pulmonary aspiration of gastric contents is a leading cause of anesthesia-related morbidity and mortality, particularly in emergency surgeries and among patients who are not appropriately fasted prior to airway intervention. The application of cricoid pressure (CP), also known as the "Sellick maneuver" is the current clinical practice to prevent aspiration of gastric content during Rapid-sequence induction (RSI) of general anesthesia. This conventional CP uses manual pressure over the cricoid cartilage during RSI procedure for patients at high risk of aspiration. Since its incorporation into clinical practice, the utility and technique of CP have garnered considerable debate, mainly due to the inability to standardize the magnitude and consistency of the applied force. Too little force may be ineffective at preventing regurgitation and excessive force may impede ventilation and actually worsen laryngoscopy views, making intubation more difficult. A significant challenge in current clinical practice of CP is the inconsistency in the force applied, which often falls short of the necessary intensity and duration. To address this issue, we developed a groundbreaking handheld device capable of monitoring applied pressure in real-time, aiding providers in delivering precise and reproducible CP. Furthermore, our device utilizes sensor fabrication technology, integrating microelectronic systems and microprocessors to measure and display force in real-time, all while remaining portable. However, before implementation in clinical practice, rigorous testing through human volunteer studies and subsequent clinical trials is imperative. Hence, this study aims to validate the efficacy of our novel CP device in helping Providers apply the accurate target force.
