Sleep Apnea Medical Glossary – Frequently used Medical Terms
Apnea Hypopnea Index. Average number of apneas and hypopneas per hour of sleep.
Self-titrating CPAP, auto-adjust CPAP, APAP). A non-invasive/non-pharmacologic positive airway pressure device designed to vary pressures to meet the needs of the patient’s sleep-disordered breathing. Pressure changes are determined by monitoring variably a combination of apneas, hypopneas, inspiratory flow limitation, and snoring. Instead of constant maximal pressure (as delivered with conventional CPAP), these systems provide the minimal pressure necessary to stabilize the upper airway. AutoPAP is often used to determine effective positive airway pressures for a patien
A cessation of airflow. For diagnosis of OSA, the cessation should be at least 10 seconds long, and the event can be considered obstructive if during apnea, there is an effort to breathe.
Alert Well And Keeping Energetic. An educational support group for patients with obstructive sleep apnea and their significant others.
Continuous Positive Airway Pressure. A non-invasive/non-pharmacologic method of applying positive pressure to the upper airway via a blower and mask/interface to pneumatically splint the upper airway, thereby preventing collapse.
Expiratory Positive Airway Pressure
Epworth Sleepiness Scale
For diagnostic purposes in OSA, an abnormal respiratory event lasting at least 10 seconds with at least a 30% reduction in thoracoabdominal movement or airflow as compared to baseline, and with at least a 4% oxygen desaturation.
Inspiratory Positive Airway Pressure
Obstructive Sleep Apnea
Obstructive Sleep Apnea Syndrome
Positive Airway Pressure
Radio frequency ablation of the soft palate and tongue base; a minimally invasive surgical procedure perform through the administration of microwave radiofrequencies to the treated tissue of the soft palate and/or the tongue base with a needle-implanted probe.
Uvulopalatopharyngoplasty. The surgical resection of the obstructive portion of the velar musculature of the soft palate and the entire uvula.
