Sleep Studies, Campbelltown

Snoring, waking tired or told you stop breathing at night? A Level 2 sleep study can tell you if obstructive sleep apnoea is putting pressure on your heart. We fit it in our clinic, and you sleep in your own bed.

How Your Sleep Affects Your Heart

Obstructive Sleep Apnoea (OSA) is more than a snoring problem. Each time your airway closes during sleep, your oxygen levels drop and your heart has to work harder. Over time, untreated OSA is linked to high blood pressure, atrial fibrillation and other heart rhythm problems.

As a cardiology and heart rhythm practice, we see this link every day. Testing for sleep apnoea is often an important part of understanding and managing your heart health.

Signs You May Need a Sleep Study

A sleep study may be worth discussing with your doctor if you:

  • Snore loudly or regularly
  • Have been told you gasp, choke or stop breathing in your sleep
  • Wake up unrefreshed, even after a full night
  • Feel drowsy or struggle to concentrate during the day
  • Wake with headaches or a dry mouth
  • Have high blood pressure, atrial fibrillation or another heart rhythm condition

What Is a Level 2 Sleep Study?

A Level 2 sleep study is a comprehensive, unattended overnight test focused on detecting obstructive sleep apnoea. It records much of the same detail as an in-lab study, but you get to sleep at home.

What we measure:

Brain activity (EEG)
tracks your sleep stages
Nasal pressure

measures your breathing

Blood oxygen (oximetry)
shows drops in oxygen levels
Heart rate and ECG
monitors your heart rhythm overnight
Respiratory effort
records chest and abdominal movement
Leg movements
picks up restless or periodic movement
Body position
shows whether position affects your breathing
