Only about half of the people who need a CPAP are successful wearing the device, says Dr Maria Vega, a sleep physician at Temple University Hospital, reports KYW Newsradio. 

“I usually tell my patients to try to use the CPAP or the mask during the day and not that they need it because they don’t have pauses when they’re awake. But it helps them get used the mask, so when the night comes, they’re more used to the CPAP and the mask and they can feel less claustrophobic,” Vega said.
