Table 3.

Potential biopsychosociotechnical considerations for selecting a CPAP interface.

Bio	Moderate-to-severe obstructive sleep apnea Wears a beard; intends to keep it Primarily a back sleeper
Psycho	Moderate level of motivation to adhere to treatment Does not want to “have to get an engineering degree” to use the mask
Socio	Married, shares bed with spouse Concerned about “looking ridiculous” and “unsexy” Insurance covers all standard types of CPAP interface
Technical	Oronasal mask likely “too much” and would make it hard to respond to spouse's conversation Oronasal mask (especially) and nasal mask may leak with beard Nasal pillow may leak less with beard, is less bulky and less obstructive
Recommendation	Trial of nasal pillow
