Hi Yvonne,

Alcohol, being a sedative, will increase the tendency of airway obstruction to occur (and the severity of the events as well). Because of this, CPAP pressures which were titrated based upon data derived from a study which was done when no alcohol was in the person's system may no longer be adequate to prevent apneas from occuring. Therefore if you are contemplating beginning customary nightcaps, I would recommend consulting with your physician, as higher pressure settings will likely need to be ordered.

Some CPAP equipment (i.e. Sleepnet D-PAP, Respironics Virtuoso, etc.,) is set up to function within a range of pressures, delivering only the necessary amount of pressure required, assessed by the machine on a breath-by-breath basis. In this kind of equipment pressure ranges are set to anticipate higher pressure requirements which may occur when the user consumes more than his/her usual amount of alcohol (or any other sedative; or may be suffering a bout of allergies, or common cold, etc.) and may therefore be set properly to meet the increased pressure requirement already. But straight CPAP gear is usually set to whatever pressure was required the night of the CPAP study, and consequently may not be sufficient under other (sedative) conditions.

Again, I recommend consulting with your physician/sleep lab.

Hope this helps.

Brian
