Pulmonary Services

Pulmonary Function Laboratory

The Pulmonary Function Laboratory meets both outpatient and inpatient diagnostic needs.  Routine studies include spirometry, flow volume loops, maximal voluntary ventilation, diffusion capacity and lung volumes by both plethysmography (with or without airway resistance) and Nitrogen washout methods, arterial blood gases, and MIP (NIF) and MEP measurements (Maximal Inspiratory Pressure or Negative Inspiratory Force and Maximal Expiratory Pressure).

Specialized studies include bronchoprovocation for the diagnosis of asthma utilizing exercise and/or a Methacholine challenge and a complete airway challenge evaluation (“CACE”) study.  Nocturnal oximetry studies are also performed for those with nocturnal hypoxemia related to chronic obstructive or restrictive pulmonary disease and congestive heart failure.  Six minute walk tests are also performed for both desaturation and or distance studies.

These services are accessible to both Hershey Medical Center physicians as well as physicians who are not in the HMC system.
