Pulmonary Function Testing

Pulmonary function testing (PFT) is used to measure how your lungs function. PFT can include simple screening spirometry, lung volume testing, arterial blood gas analysis, diffusing capacity testing, and cardio-pulmonary exercise testing. The results are used by providers to evaluate respiratory symptoms such as dyspnea and coughing and can aid in diagnosing asthma, emphysema and chronic obstructive pulmonary disease. Our respiratory therapists perform all non-invasive testing and also support the physician team with advanced testing such as bronchoscopy and lung biopsy. Available tests include:

  • Screening spirometry
  • Spirometry with pre & post bronchodilation
  • DLCO
  • Lung volume and resistance
  • Full PFTs (includes all of the above)
  • MMV
  • Sputum induction
  • Inhaled Pentamidine
  • Arterial blood gas analysis
  • Methacholine Challenge (Pediatric patients require a Pulmonology referral)
  • Cardio-Pulmonary exercise testing (requires a Pulmonary or Cardiology referral)
  • Indirect Calorimetry
