I’m on a pulmonary and sleep medicine rotation and something we see everyday is Obstructive Sleep Apnea.
20-30% of males and 10-15% of females in North America have OSA.
What during the H and P would put OSA as high suspicion on our radar?
STOP-BANG is a helpful way to remember the screening questions.
•Does the patient SNORE loudly?
•Do they often feel TIRED during the daytime?
•Has anyone OBSERVED them stop breathing during sleep?
•Do they have or being treated for high blood PRESSURE?
•NECK circumference > 40cm
•GENDER - Male
How is OSA diagnoses?
In lab polysomnography also known as a sleep study. During the sleep study they will measure how many apneic events per an hour the patient has.
0-5 is normal, 5-15 is mild, 15-30 is moderate and > 30 is severe.
How do we treat?
Treatment depends on your classification and your symptoms. Treatment can include dental appliance, cpap machine (like the one I’m holding here) and surgery. Also everyone benefits from diet and exercise for weight loss! Talk to your PCP or sleep medicine physician to determine your best treatment or if you think you might have sleep apnea.
Now most importantly why do we care??
OSA untreated can increase cardiovascular disease including hypertension, CAD, arrhythmias, HF and stroke.
Day time sleepiness can decrease your cognition and driving drowsy is dangerous!
Patients with OSA have increase prevalence of DM type 2 and may contribute to fatty liver disease. They also have higher risk of complications during surgery!
