When diagnosed with sleep apnea, Sleep South will provide a support program for patients prescribed a Positive Airway Pressure device with a Continuous positive airway pressure ventilator (CPAP). A CPAP is a form of positive airway pressure ventilator which applies mild air pressure on a continuous basis to keep the airways continuously open. It is very important to follow the guidelines of the therapy and wear your CPAP device continuously during sleep to best combat the negative effects of sleep apnea.
