The Cecily & Robert Harris Pulmonary Diagnostic Center, specializing in state-of-the-art pulmonary function testing (PFT) and cardio-pulmonary exercise testing (CPET), is one of the largest and busiest laboratories in the New York area. The Center is staffed with Board certified physicians, Registered Nurses, Respiratory Therapists, Exercise Physiologists and PFT technicians who specialize in the care of adult patients with breathing problems. American Thoracic Society standards for quality assurance and quality control are diligently met and documented.  Pursuant to the goals and mission of NewYork-Presbyterian/Columbia University Medical Center, the staff is involved in many clinical research programs evaluating evolving treatments for pulmonary disease.

Pulmonary Function Testing (PFT)

The PFT laboratory provides comprehensive testing options such as spirometry with and without bronchodilator, and/or bronchial provocation, lung volume testing by plethysmography and nitrogen washout, lung diffusing capacity, maximal respiratory muscle pressure assessment, maximal voluntary ventilation assessment, assessment of upper airway function, exercise and rest pulse oximetry, arterial blood gas measurements, and assessment of physiologic shunt fraction.  These measurements are used to evaluate the status of a patient’s lung health and/or investigate the cause of respiratory symptoms as well as evaluate prescribed treatments.

Cardiopulmonary Exercise Testing (CPET)

The CPET laboratory allows for the assessment of cardio-pulmonary function during incremental exercise (bicycle ergometry) and combines the routine measurements of the electrocardiogram (ECG), blood pressure, pulse oximetry and power output with the analysis of exhaled gases. CPET is used to evaluate unexplained or exercise-induced dyspnea; to determine whether exertional limitations are primarily cardiovascular or pulmonary in nature; document exercise-induced hypoxemia; detect covert respiratory dysfunction in patients with interstitial or pulmonary vascular disease; assess response to treatment and pre-surgical risk for pulmonary resection. A recently added component is Optoelectronic Plethysmography (OEP), a system that uses infrared cameras and small reflective markers to measure the movement of the chest wall and abdomen to assess changes in lung volumes.
