Abstract

Objective. To develop a quick, simple, bedside test for determining continuous positive airway pressures CPAP for obstructive sleep apnea OSA patients. Study Design. Prospective case series at a tertiary medical center. Methods. The Five-Minute Awake Snoring Test for Determining CPAP Five-Minute CPAP Test was developed and tested. Patients wear a soft-gel nasal triangle mask while holding a tongue depressor with the wide section 1.75 cm between the teeth. Fixed pressure nasal CPAP is applied while the patient simulates snoring at 4 centimeters of water pressure. The pressure is incrementally titrated up and then down to determine the lowest pressure at which the patient cannot snore Quiet Pressure. Results. Overall, thirty-eight patients participated. All could simulate snoring. Correlation coefficients were statistically significant between Quiet Pressures and body mass index strong positive relationship, , apnea-hypopnea index moderate positive relationship, , lowest oxygen saturation moderate negative relationship, , and oxygen desaturation index strong positive relationship, . Conclusion. This pilot study introduces a new concept, which is the final product of over one year of exploration, development, and testing. Five-Minute CPAP Test is a quick, inexpensive, and safe bedside test based on supine awake simulated snoring with nasal CPAP.
