Sleep Facility


Investigators use the Sleep Facility to intensively study phenomena that occur partially or entirely during sleep or as a consequence of sleep deprivation. The Sleep Facility is closely integrated with the Cardiovascular Facility and both are directed by Virend Somers, M.D., Ph.D., making the Sleep Facility uniquely suited to study the interactions between sleep and cardiovascular disease.

Services and equipment

Overnight studies are conducted both in the Sleep Facility and in patient rooms at Mayo Clinic Hospital, Saint Marys Campus. Long-term inpatient studies are conducted in the Saint Marys CRTU. In special situations, the facility can arrange off-site sleep studies. Facility personnel have extensive experience conducting studies combining cardiovascular and sleep physiology, and services are enhanced by dedicated bioengineering support.

Accessing the facility

Investigators planning a new study in the Sleep Facility should discuss their protocol with Dr. Virend Somers, facility director.

Before using the facility, investigators must receive approval from the Institutional Review Board (IRB) and the Center for Clinical and Translational Science (CCaTS) (via the CRTU section in IRBe). Once approvals are received, study teams work with sleep technologist Ann B. Peterson and CRTU staff to schedule time in the facility.
