Evaluating How Your Lungs Perform

Pulmonary diagnostic tests are a series of tests which evaluate how well the lungs are performing. These tests may be performed to help diagnose disease, monitor disease progression or therapeutic intervention over time, to evaluate disability, or as a variable in research studies. 

Preparing for Your Visit

The tests are ordered by your physician and may take anywhere from 10 to 90 minutes to perform. All results are interpreted by a board-certified pulmonologist.  The referring physician should receive the results within approximately three business days of the testing.

Before testing:

  • Don't use a pulmonary bronchodilator at least four hours before test time.
  • If you will need to exercise, please bring sturdy walking shoes and wear comfortable clothing.
  • If a metabolic test is ordered, eat only a light meal prior to the study.

Please be prepared to tell the exercise specialist the following:

  • Medications you are currently taking, including inhalers, pills, or nebulizer treatments
  • Allergies to medications
  • 亚洲自慰视频 problems
  • Smoking history, including how many years you have smoked and how many packs per day
  • Recent illnesses
  • Any symptoms, such as shortness of breath, chest pain, dizziness, and nausea

All Pulmonary Diagnostic Tests

The pulmonary lab at 亚洲自慰视频 of Utah Hospital conducts a full range pulmonary diagnostic testing. Your doctor will order the specific tests appropriate for your diagnosis and they will receive the results in approximately three business days.

  • Spirometry (including bronchodilator responsiveness testing)
  • Slow Vital Capacity
  • Maximal Voluntary Ventilation
  • Carbon Monoxide Diffusion Capacity
  • Plethysmography/Lung Volume
  • Single Breath Gas Dilution
  • Maximal Inspiratory and Expiratory Pressure (MIP and MEP)
  • Bronchial Challenge Testing (Methacholine and Exercise)
  • Cardiopulmonary Exercise Testing
  • Arterial Blood Gas Analysis
  • Pulse Oximetry
  • Right to Left Shunt
  • Six Minute Walk Testing

Indications for Spirometry

  • Detect the presence of disease
    • History of pulmonary symptoms
    • Physical indicators
    • Abnormal laboratory findings
  • Needed to make the diagnosis of COPD
  • Quantify the extent of known disease on lung function and the progression of pulmonary disease.
    Identifies people with a rapid decline in lung function
  • Measure the effects of occupational or environmental exposure
  • Determine the benefits or side effects of therapy
  • Assess risk for surgical procedures
  • Evaluate disability or impairment

Indications for Pre- and Post- Bronchodilator Tests

  • Assess bronchodilator responsiveness
  • Evaluation of alternative drug regimens in patients with known hyper-reactive airways.
  • Disability determinations when FEV1 is less than the lower limit of normal.
  • Preoperative evaluation when airway obstruction is present.

Indications for Spirometry

  • Relative Contraindications:
    • Known or suspected adverse reactions to a specific bronchodilator
    • Unstable cardiovascular status that might be aggravated by beta adrenergic stimulation    

Indications for Single Breath Carbon Monoxide Diffusing Capacity (DLCO)

  • Evaluation of diseases which involve lung parenchyma.
  • Evaluation of emphysema.
  • Differentiating between chronic bronchitis, emphysema, and asthma.
  • Evaluation of pulmonary involvement in systemic diseases.
  • Evaluation of the pulmonary effects of chemotherapy agents or other drugs known to have pulmonary toxicity.
  • Impairment/disability evaluation.

Indications for Lung Volumes

  • Establish or confirm a diagnosis of "restrictive ventilatory defect."
  • Aid in the interpretation of other lung function tests.
  • Quantify the amount of nonventilated lung before lung volume reduction surgery.

Indications for Inspiratory and Expiratory Pressures (MIP and MEP)

  • Assess and quantify the degree of respiratory muscle weakness in neuromuscular disease.
  • MEP may help in determining the potential for effective cough and the ability to move secretions.
  • Evaluate probability of successful weaning from a ventilator.
  • Relative Contraindications:
    • Angina, recent MI, uncontrolled systemic hypertension.
    • Recent pneumothorax.
    • Lung biopsy within the previous week.

Indications for Methacholine Challenge Testing

  • Diagnosis of asthma when clinical picture is confusing.
  • Relative Contraindications:
    • FEV1 percent predicted <60%.
    • Pregnancy.
    • Nursing mothers.
    • Cholinesterase inhibitor medication.

Indications for Cardiopulmonary Exercise Testing with Gas Exchange Measurement

  • Evaluation of unexplained dyspnea.
  • Determine exercise capacity and impairment.
  • Differentiate between cardiac and pulmonary causes of dyspnea.
  • Rehabilitation evaluation.
  • Pre operative evaluation.
  • Impairment/disability evaluation.

Indications for Arterial Blood Gas Analysis

  • Evaluation of ventilation, acid base balance, and oxygenation.
  • Quantification of a patient's response to oxygen therapy.
  • Monitoring of disease process.

Indications for Six-Minute Walk Test

  • Assess SpO2 at rest and with exertion in patients suspected of hypoxemia.
  • Evaluate the symptom of dyspnea.
  • Assess the degree of impairment.
  • Evaluate therapeutic intervention.

Indications for Pulmonary Right to Left Shunt Testing

  • Determine unexplained hypoxemia.
  • Determine the extent of pulmonary A-V malformation involvement in known disease or suspected disease, e.g., HHT.
