For Clinicians

We offer portable domiciliary sleep studies, which are performed in the comfort of the patients own home giving a greater understanding of the patients natural sleeping patterns.

This method of sleep screening provides early upper airway and obstructive sleep apnea detection, ECG, EOG, overnight oxygen saturation levels and a general overview of the quality of a patients sleep.

For Patients

Your doctor can refer you to us for a home sleep study.
This is an overnight Sleep Apnoea study, which is performed in the comfort of your own home.


Our sleep technicians will provide you the equipment, a demonstration and written instructions for carrying out the study.



What is overnight Oximetry?

Oximetry is a test that measures your heart rate and the amount of oxygen in your blood.

When this is done overnight, a continuous measurement can be graphed. The graph helps the doctor see if you have enough oxygen in your body when you sleep. The machine records the information and the respiratory therapist prints it out in the morning for the doctor to review.



Why do I need overnight Oximetry?

Doctors often like to monitor blood oxygen levels to see if you have enough oxygen at night.

The results help the assessment and treatment of your medical condition. 



Spirometry is the lung function test of choice for both diagnosis and assessment of asthma and other lung diseases; the measurement of peak expiratory flow with conventional peak flow meters has significant limitations.


Most adults and children over 7 years of age can perform a spirometry.

The aim of spirometry is to assess variability of airflow obstruction, and to measure the degree of airflow obstruction compared to predicted normal. Accurate measurement of respiratory function is necessary to assess and manage asthma and lung problems.





Ambulatory blood pressure (ABP) monitoring involves measuring blood pressure (BP) at regular intervals (usually every 20–30 minutes) over a 24 hour period while patients undergo normal daily activities, including sleep.


The portable monitor is worn on a belt connected to a cuff on the upper arm and uses an oscillometric technique to detect systolic, diastolic and mean BP as well as heart rate.


When complete, the device is connected to a computer that prepares a report of the 24 hour, day time, night time, and sleep and awake (if recorded) average systolic and diastolic BP and heart rate.



A Holter Monitor is a small device which continuous records the rhythm of the heart for 24 to 48 hours. This information gained will help the doctor in identifying and evaluate health issues, such as chest pain, irregular heartbeats or palpitations.


This test requires the electrodes to be attached to your chest and abdomen. It contains lead wires that connect to a small monitor box, which is be attached to an item of clothing, such as a belt or pocket.


The Holter Monitor is to be worn throughout normal daytime activities, such as household chores and exercise- unless instructed differently. You will be instructed to keep a diary of your activities during the recording period, and you should write down the date and time of each activity and if you experience any particular symptoms, such as dizziness, palpitations, chest pain or other previously experienced symptoms.
