Understanding Sleep Apnea and STOP-BANG
What is Sleep Apnea?
Sleep apnea is a serious sleep disorder where breathing repeatedly stops and starts during sleep. The most common type is obstructive sleep apnea (OSA), where the throat muscles relax and block the airway during sleep.
Health Consequences
- •Increased risk of cardiovascular disease
- •High blood pressure
- •Type 2 diabetes
- •Stroke
- •Depression and anxiety
STOP-BANG Validation
The STOP-BANG questionnaire is a validated screening tool with high sensitivity for detecting moderate to severe OSA. It has been extensively studied and is widely used in clinical practice.
Diagnostic Accuracy
Note: High sensitivity means the test is good at identifying patients who have OSA, but further testing (sleep study) is needed for definitive diagnosis.
