1
Q

What is OSA?

A

Involves cessation or significant decrease in airflow in the presence of breathing effort

Characterized by recurrent episodes of upper airway collapse during sleep

OSA that is associated with excessive daytime sleepiness is commonly called obstructive sleep apnea syndrome

Q

How does OSA present?

A

Night time:

  • Snoring (loud, habitual, bothersome to others)
  • Witnessed apnoea’s, which often interrupt the snoring and end with a snort
  • Gasping/choking sensations that arouse from sleep
  • Nocturia
  • Insomnia
  • Restless sleep

Daytime:

  • Nonrestorative sleep (waking up as tired as when they went to bed)
  • Morning headache, dry or sore throat
  • Excessive daytime sleepiness (EDS)
  • Cognitive deficits
  • Personality and mood changes

Q

How should OSA be Ix and Mx?

A

Ix = BMI, TFT (hypo), CXR (obstructive lung disease), ECG (R ven failure), sleep study

Lifestyle advice = weight loss, exercise, reducing alcohol intake and sedative use, and smoking cessation

Refer to a sleep centre = confirmation of Dx, using sleep studies (polysomnography or limited sleep study)

CPAP = for moderate or severe OSAS

Intra-oral devices (mandibular advancement device) = people who snore or have mild OSAS
