Pulmonary Laboratory

The Capitol Medical Center Pulmonary Laboratory is equipped with modern facilities to serve the diagnostic and therapeutic needs of patients with acute and chronic pulmonary disorders. It offers a wide range of pulmonary function testing (lung function) and exercise test to assist physicians in diagnosing and managing patients with breathing problems and/or lung disease. These include ultrasonic nebulizers for the administration of drugs continuous humidification and in-line nebulizers, intermittent positive pressure breathing (IPPB) and well maintained volume respirators for those requiring mechanical ventilator support. It also offers Pulmonary Function Tests (Spirometry) for the diagnosis and management of obstructive and restrictive pulmonary disorders.

Healthy Lungs To Healthy Life. Breathe Easy.

The Pulmonary function tests help measure the different aspects of lung function and can help determine the cause of shortness of breath and may help confirm lung diseases such as asthma, bronchitis or emphysema. The tests are also used to measure how a lung disease in progressing or how serious the lung disease has become. Pulmonary function tests can also be used to assess how a patient is responding to different treatments.


Pulmonary Laboratory Services

Our Pulmonary Laboratory offers a variety of services that will lead patients to better recovery. Such services are as follows:

  • MAXIMAL INSPIRATORY PRESSURE / MAXIMAL EXPIRATORY PRESSURE (MIP/MEP) This is a test of total respiratory muscle strength.  In one part of the test, you are asked to attempt to inhale as forcefully as possible against a blocked tube.  In the other part of the test, you are asked to attempt to exhale as forcefully as possible against a blocked tube.  In both cases, the pressure you generate while attempting to inhale or exhale is recorded.  This pressure correlates with the overall strength of the breathing muscles and may be helpful in assessing possible respiratory muscle weakness.
  • AIRWAY RESISTANCE (Raw/Gaw) – Airway resistance can be directly measured during Body Plethysmography, which determines the pressure required to produce a given flow. For this test, you sit in a “booth” and breathe through a mouthpiece while pressure and airflow measurements are collected.
  • LUNG DIFFUSION CAPACITY (Dlco) – This test measures how well oxygen passes from your lungs to your bloodstream. During this test, you breathe in a type of gas through a tube. You hold your breath for a brief moment and then blow out the gas.
  • LUNG VOLUMES Lung volumes provide useful information that confirms the presence of restrictive lung disease suggested by a low vital capacity on a spirometry test.
  • ARTERIAL BLOOD GASES– An arterial blood gas (ABG) test measures the acidity and the levels of oxygen and carbon dioxide in the blood from an artery. This test is used to check how well your lungs are able to move oxygen into the blood and remove carbon dioxide from the blood. Blood for an ABG test is taken from an artery. Most other blood tests are done on a sample of blood taken from a vein, after the body’s tissues where the oxygen is used up and carbon dioxide is produced.
  • SLEEP CENTER –  Diagnostic and therapeutic sleep studies provide clinical advice and education about CPAP and other therapies for sleep disordered breathing.
  • INCENTIVE SPIROMETRY EXERCISES – Our lab performs several types of exercise testing consisting of baseline spirometry, a period of vigorous exercise, and repeat spirometry at defined intervals.
  • PULSE OXIMETRY- SpO2 – Pulse oximetry and arterial blood gas tests show how much oxygen is in your blood. During pulse oximetry, a small sensor is attached to your finger or ear. The sensor uses light to estimate how much oxygen is in your blood. This test is painless and no needles are used.
