Our Cardiopulmonary department does a variety of different outpatient exams. Please call us at 830.703.1742 to make an appointment.

Pulmonary Function Test

PFTs are non-invasive tests that show how well the lungs are working. The tests measure lung volume, capacity and rates of flow. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders. You will need a list of current medications as well as any allergies you are aware of. Without this information, the exam cannot be performed. If you take any breathing treatments or inhalers, they must not be taken 8 hours prior to exam. This exam is by appointment only and will take about 1 hour.

Bedside Spirometry

The measurement of the breathing capacity of the lungs, such as in pulmonary function tests. This exam is by appointment only.


EEG is an electrophysiological monitoring method to record electrical activity of the brain. It is noninvasive, with electrodes placed along the scalp and measures voltage fluctuations resulting from ionic current within the neurons of the brain. You will need to bring a list of medications taken prior to exam and a patient history. This exam is by appointment only and can take about 1 hour.

Tilt Table

A tilt table test is used to evaluate the cause of unexplained fainting (syncope). For a tilt table test, you begin by lying flat on a table. Straps are put around your body to hold you in place. After about 15 minutes of lying flat, the table is quickly tilted to raise your body to a head-up position—simulating a change in position from lying down to standing up. The table will then remain upright for up to 45 minutes, while your heart rate and blood pressure are monitored. This allows doctors to evaluate your body's cardiovascular response to the change in position. This exam is by appointment only and a list of current medications will be needed.


EKG or ECG is a test that checks for problems with the electrical activity of your heart. An EKG shows the heart's electrical activity as line tracings on paper. No appointment is needed for this exam.

Arterial Blood Gas

Measures the acidity (pH) 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. No appointment is needed for this exam.
