Pulmonary Function Laboratory at Mount Zion

U.S. News Best Hospitals

The Pulmonary Function Laboratory at Mount Zion provides comprehensive testing for lung disease and provides pre-operative "workups" to test lung function before surgery.

Some of the standard pulmonary function tests are:

  • Blood gas measurement
  • Diffusing capacity
  • Exercise testing (Six-minute walk test) — Evaluates oxygen saturations, measured by finger or ear probe
  • Lung volume — Special gas mixture is inhaled, then slowly exhaled. Gas volume in the lung is measured.
  • Spirometry — Measures volume and speed of air that is inhaled and exhaled

More specialized tests include:

  • Maximal inspiratory and expiratory pressures — Measures strength of respiratory muscles.
  • Maximal voluntary ventilation — Measures amount of air inhaled and exhaled in one minute
  • Methacholine challenge — Methacholine causes airways to contract in patients with asthma. Patients inhale methacholine aerosol mist before and after spirometry. Test indicates asthma, if lung function drops by at least 20 percent.

Depending on your health insurance, you may need a referral from a primary care doctor.
