Choosing a mask for a sleep apnea machine is an essential process when using this technology for a better night’s sleep. Many people who been prescribed a CPAP (Continuous Positive Airway Pressure) machine for sleep apnea are thrilled to discover how their new mental sharpness and increased energy affects their life. Getting a good night's sleep is paramount for those people who have suffered for years without getting a diagnosis. However, some people find wearing a CPAP mask extremely uncomfortable, and struggle to find a mask that fits them correctly. It takes approximately two to twelve weeks to get used to wearing a CPAP mask at night, and patients must work through some mild, temporary side effects, including sore eyes, nasal congestion, abdominal bloating and headaches. Finding the correct mask is a process unique to each individual. While there are many types of masks available, the top three most popular CPAP masks include full face masks, nasal pillow masks, and hybrid or multi-fit masks. Consider these questions when searching for the right mask for a sleep apnea machine.
