In‑Hospital Sleep Study

An In‑Hospital Sleep Study is an overnight assessment that monitors how your body functions while you sleep. Using specialised equipment, we track your brain activity, breathing, heart rate, oxygen levels, and movement throughout the night. This helps our clinicians identify conditions such as sleep apnea, snoring, and other sleep disorders, so you can receive the right care and treatment.        

What happens during an In‑Hospital Sleep Study?  

- Initial check: When you arrive at the hosipital, a nurse and CRS technologist will check your vital signs and take a few reference photos to support accurate interpretation of your sleep study results. A brief respiratory test (spirometry) will also be performed to assess lung function.

- Set-up: The sleep study set‑up takes about 60 minutes. A series of leads and sensors are placed around your head, face, chest, and legs. Signals are checked verified before you sleep.

- Overnight monitoring: Each lead/sensor serve a unique purpose to provide a holistic overview of your sleep, including:  

 - Brain wave activity  

 - Heart activity  

 - Oxygen levels

 - Breathing patterns

 - Limb movements  

- Purpose of leads: Each lead has a unique role, so applying them correctly is important for accurate results.  

Technologists explain each step of the process and make sure you are comfortable before the study begins.

Preparation Instructions

Please have a shower prior to arrival. Ensure you have clean hair and skin. Do not apply moisturisers, make-up or oils to the skin. Facial hair must be cleanly shaven, especially around the chin and jaw line as stubble prevents proper lead attachment. A full-length beard may be acceptable however you may be asked to shave if deemed necessary. Please remove nail polish or acrylic/artificial nails from either your ring or middle finger to allow placement of the oxygen monitoring probe. Appropriate loose clothing or sleepwear is required – please come dressed in pyjamas or a modest top with shorts/pants. For males who prefer to sleep without a shirt, sensors can be applied directly to the chest; however, please be aware there is a risk of skin irritation.

Spirometry preperation: Avoid strenuous exercise for 1 hour prior to the test. Certain respiratory medications may need to be witheld. These will be advised by our staff when scheduling your appointment.
