Diagnostic Testing

Pulmonary Function testing


Spirometry tests for abnormal lung function (airflow obstruction) by measuring the ability of the lungs to move large volumes of air quickly through the bronchial tubes.

Lung Volumes

Measurement of the volume of air in different phases of the respiratory cycle is used to determine lung capacity.

Diffusing Capacity

Diffusing capacity determines the ability of the lungs to transport gas into and out of the blood.

Specialized Asthma testing

Exhaled Nitric Oxide measurement

Nitric oxide is a gaseous molecule that is produced by certain types of inflammatory cells. Fractional exhaled nitric oxide (FeNO) is a measurement of airway inflammation that helps to identify, treat, and manage steroid-responsive patients with asthma.

Bronchial Challenge testing

Bronchial Challenge testing involves breathing in a compound that may result in narrowing of the airways. This test is used to assist in the diagnosis of asthma.

Oxygen testing

Oxygen Evaluation

Pulse oximetry monitors a patient’s oxygen level (saturation) by using a sensor that is placed on the fingertip or earlobe.

Exercise pulse oximetry

Pulse oximetry measurements are done in the clinic during exercise (such as walking or climbing stairs) to assess for low oxygen levels with activity.

Overnight pulse oximetry

Pulse oximetry measurements are done overnight at home to assess for low oxygen levels during sleep.

Cardiopulmonary Exercise testing

Six-minute walk test

The six-minute walk test measures the distance walked over 6 minutes. This is a sub-maximal exercise test that assesses aerobic capacity and endurance.

Shape exercise test

The Shape exercise test is a non-invasive measurement of the cardiovascular and respiratory systems during exercise and is used to assess exercise capacity.
