PULMONOLOGY

The division of pulmonary and sleep medicine provides comprehensive care to infants, children and adults suffering from respiratory disorders. The division is committed to excellence and is nationally recognized for quality of patient care, education and research. Care is guided in all age groups by the routine measurements of lung function. Comprehensive multi-disciplinary care is provided by physicians, nurse practitioners, nutritionists, physical therapists and social workers.

SLEEP LAB

Polysomnography is used to diagnose, or rule out many types of sleep disorders including narcolepsy, restless legs syndrome, REM behavior disorder, parasomnias, and sleep apnoea. It is a diagnostic test during which a number of physiologic variables are measured and recorded during sleep. Physiologic sensor leads are placed on the patient in order to record:

  • Brain electrical activity : EEG for sleep architecture
  • Eye and jaw muscle movement : EOG and EMG
  • Leg muscle movement : Leg EMG
  • Airflow : Detection of Apnoea
  • Respiratory effort: Differentiation between obstructive and central apnoea
  • EKG : Cardiac activity
  • Oxygen saturation : Oxygen desaturation during apnoea

Information gathered from all leads is fed into a computer and outputted as a series of waveform tracings which enable the physician to visualize the various waveforms, assign a score for the test, and assist in the diagnostic process.

  • Excessive daytime sleepiness
  • Loud or disruptive snoring
  • Gasping or choking during sleep

Possible increased risk for

  • High blood pressure
  • Heart disease and heart attack
  • Stroke
  • Fatigue-related motor vehicle and work accidents
  • Decreased quality of life
