General Introduction
Cansleep provides a comprehensive, specialist sleep physician-led service incorporating clinical assessment, diagnostics, and treatment across a range of sleep disorders, including obstructive sleep apnoea, insomnia, narcolepsy and parasomnias.
Cansleep provides consultation in Christchurch and can provide couriered home-based sleep studies throughout the South Island.
We are committed to delivering a high quality, patient focused-service in a clinically relevant time frame. Our aim is to keep our patients and primary care colleagues involved and informed throughout this process.
Clinical Assessment
Patients with suspected sleep disorders can be referred for a full physician consultation.
Physician assessment
Sleep Diagnostics
Cansleep provides a range of sleep studies which will be tailored to individual patients depending on the clinical circumstances. These are performed as home-based studies. Sleep studies available include:
Overnight oximetry (Level 4 Sleep Study)
Compass study (Level 4a Sleep Study)
Level 3 Sleep Study
Full Polysomnographic Sleep Study (Level 2 Sleep Study)
Cansleep Management of OSA – CPAP
The majority of patients with significant OSA are referred for a trial of CPAP. Cansleep provides a comprehensive approach to initiation and maintenance of patients on CPAP treatment. This includes several stages which include:
Initial set-up
At the start of a CPAP trial, patients have an hour-long session which includes mask fitting, education regarding use of CPAP and potential problems, and machine selection and set-up. It has been shown that long term-compliance and response to CPAP is directly related to proper mask fitting and education early on in any CPAP trial.
4 week autotitratring CPAP trial
Patients generally undergo a 4-week trial of autotitrating CPAP. This allows for early assessment of tolerance, clinical response and compliance. It also provides information regarding potential leak and therapeutic pressure requirements. During this period there is online monitoring and regular contact with Cansleep staff to check progress and adjust masks or alter machine settings as required.
Transfer to long-term PAP treatment
Following the initial 4-week trial period patients may opt to remain on autotitrating CPAP, while short-term rental options are also available for those waiting for alternative treatment options such as ENT surgery.
Ongoing support
Once patients are established on CPAP ongoing support is available from Cansleep as required. Patients are encouraged to return for a annual review or sleep “warrant of fitness” to ensure ongoing optimal management of sleep-disordered breathing. Two free reviews are available to be used in the first year after purchase

Clinical Assessment
Patients with suspected sleep disorders can be referred for a full physician consultation.
Physician assessment
- Formal clinical assessment
- Proceed to diagnostic testing if appropriate
- Discussion of management options
Sleep Diagnostics
Cansleep provides a range of sleep studies which will be tailored to individual patients depending on the clinical circumstances. These are performed as home-based studies. Sleep studies available include:
Overnight oximetry (Level 4 Sleep Study)
- Provides a continuous recording of oxygen saturations and pulse rate overnight
- Specific but not sensitive for OSA and can miss up to 40% of severe disease
- Recommended initial test for patients with high likelihood of OSA (obese, etc etc etc)
Compass study (Level 4a Sleep Study)
- Records nasal flow, oximetry, snoring, pulse rate and body position
- More sensitive for OSA than oximetry
- Suitable as initial test for most patients with suspected OSA
Level 3 Sleep Study
- Comprehensive measurement of nasal flow, thoracic and abdominal movement, oximetry, snoring, pulse rate, ECG, body position and limb movements
- Most sensitive home-based test for investigation of OSA
- Distinguishes between central and obstructive sleep-disordered breathing
- Allows assessment of nocturnal movement disorders (restless legs syndrome, periodic limb movement disorder)
Full Polysomnographic Sleep Study (Level 2 Sleep Study)
- A very comprehensive sleep study measuring sleep staging (4 EEG channels, EOG, EMG), arousal measurement, nasal airflow, breathing effort, oxygen levels, snoring, nocturnal leg movements, electrocardiogram, heart rate and body position.
