Pulmonary Diagnostic Testing

Pulmonary Diagnostic Testing

Available tests include:

  • Pulmonary function tests
    - Spirometry
    - Lung volume
    - Gas exchange (DLCO)
    - Maximal voluntary ventilation (MVV)
    - Inspiratory and expiratory muscle pressures (PI and PE max)
    - Oxygen titration
    - Six-minute walk
    - Methacholine challenge
    - Cardiopulmonary stress
    - Fractional exhaled nitric oxide (FeNO)
    - Impulse oscillation or forced oscillation (IOS)
    - Compliance
    - High altitude simulation
  • Bronchial thermoplasty
  • Bronchoscopy
    - Autofluorescence
    - Electromagnetic navigation (ENB)
    - Endobronchial ultrasound
    - Interventional
  • Cardiopulmonary stress testing
  • Endobronchial ultrasound (EBUS)
  • Exhaled nitrous oxide testing
  • Pleural biopsy
  • Thoracentesis
  • Transbronchial needle aspiration

Biopsy techniques can now avoid conventional surgery by using minimally invasive procedures like endobronchial ultrasound (EBUS) to diagnose lung cancer and other chest diseases. A minimally invasive approach allows physicians to perform a transbronchial needle aspiration to obtain tissue and/or fluid samples from the lungs and surrounding lymph nodes. The procedure is less invasive and the recovery time shorter than conventional surgery.
