A CPAP machine delivers pressurized air to keep airways open during sleep for those with obstructive sleep apnea (OSA). Pressure settings, measured in centimeters of water (cm H2O), typically range from 4 to 20 cm H2O, with an average around 8 to 10 cm H2O. The correct pressure is determined through a sleep study called titration, which finds the lowest pressure that prevents airway collapse. Proper settings are essential for symptom relief and comfort. Adjustments should only be made under medical supervision, as incorrect pressure can cause discomfort or ineffective treatment. https://tricaredme.com/collections/cpap-machines
