Cardio Respiratory Sleep provides a full range of respiratory and sleep diagnostic services with the meticulous attention to detail that your referring doctor expects and the ease of booking you need.


Our centres are staffed by highly qualified respiratory and sleep scientists who conduct the tests, overseen and reported on by specialist physicians. Appointments can also be made for consultation with our Respiratory and Sleep Physicians. CRS is accredited for compliance with ASA Standards for Sleep Disorder Services, and, whether you opt for a home-based or in-lab sleep study, our high-quality, polysomnographic sleep tests will provide you with an accurate clinical result, not just an estimate of the likelihood of sleep apnoea.

Clinical Integration Services (CIS) Group is a private medical specialist group providing cardiac and vascular diagnostic imaging and clinical services (Cardio Vascular Services - CVS) together with sleep and respiratory services (Cardio Respiratory Sleep - CRS). With 7 clinics in the Perth Region and our newly opened Bunbury clinic, along with 2 clinics in Melbourne, we are committed to the highest quality medical service and to ensuring an excellent patient experience within a culture of courage, integrity, empathy, excellence, innovation, and collaboration.

Our strategy is to identify those who value high quality diagnostics and clinical care (both patients and referrers alike) and want more from a healthcare provider than is currently being offered elsewhere.
