the use of an instrument that blows air into the upper respiratory tract to make the airway wider or not cause obstruction while sleeping, which is called CPAP machine Continuous Positive Airway Pressure (CPAP) is suitable for people who snore and have sleep apnea.Obstructive Sleep Apnea: OSA) which refused treatment with the crown (Oral appliance) or surgery

This tool is used to cover the nose while sleeping. This mask is connected to a machine that can expel positive pressure air. The wind expelled while sleeping will support it. Do not let the airway become obstructed while inhaling.

Treatment with a CPAP machine This is the best treatment for moderate to severe obstructive sleep apnea (OSA) and should be considered in all patients before considering surgery.

8 Common Problems Using CPAP Machines And How To Fix Them

1. Unable to withstand the pressure level.	check the machine
	Gradually increase the pressure level.
	Try to insert the device while still awake.
	Reduce the pressure by 1-2 cm. of water (which is seldom recommended).
	Switch to an automatic pressure-adjusting CPAP machine (Auto-CPAP) or a bilevel positive airway pressure (BiPAP) machine.
