What this program does...

The Firestone Institute of Respiratory Care Out-Patient Sleep Assessment Program offers diagnostic and treatment services for out-patients with sleep related medical problems. These include night time snoring, gasps, breathing difficulties, limb movements, unusual behaviors, inability to fall asleep or stay asleep. Daytime complaints include unrefreshing sleep, daytime fatigue, excessive sleepiness, morning headache and may affect mood and daytime functioning. The program is available to both adults and children.

The Out-Patient Sleep Assessment Program consists of a Sleep Clinic and Sleep Lab facilities.

The Sleep Clinic operates within the Firestone Institute Of Respiratory Health located on the first floor of the Juravinski Innovation Tower. The clinic is staffed by four medical specialists with expertise in a wide spectrum of sleep disorders. During the clinic visit the sleep physician will thoroughly review each client’s sleep patterns, and sleep difficulties.

The Sleep Lab, an overnight facility is located on the fourth floor of the Juravinski Innovation Tower. This is a fully computerized nine bed lab staffed by experienced and caring registered polysonmographic technologists. During the lab visit electrodes and sensors are applied to the surface of the skin or by bands worn on the body to help gain more detailed information about sleep patterns, sleep quality, breathing patterns and movements. The monitoring devices are comfortable enough to sleep and allow position changes during the night.  The sleep technologist is available to provide courteous and respectful assistance at any time during the assessment.

Physician referral is required.

How this program helps...

The goal of this program is to assess, diagnose and determine the best treatment option for a particular sleep complaint and improve the patient’s quality of sleep and ultimately quality of life.

Most sleep disorders are associated with day time symptoms. Symptoms such as fatigue, excessive sleepiness, morning headache, mood changes can lead to reduced work/school productivity, increased accidents and general loss of quality of life. In addition, some sleep disorders can impact the quality of life of spouses and/ or other family members living within the same household. Over the long term disorders such as sleep breathing and sleep apnea may increase the risk for heart disease, stroke, diabetes and obesity.
