Pulmonary Function Tests
Pulmonary Function Tests (PFTs, Pulmonary Function Studies, Lung Function Studies/Tests, Airflow Assessment) Procedure overview What are pulmonary function tests? Pulmonary function tests (PFTs) are noninvasive diagnostic tests that provide measurable feedback about the function of the lungs. By assessing lung volumes, capacities, rates of flow, and gas exchange, PFTs provide information that, when evaluated by your doctor, can help diagnosis certain lung disorders. A normally-functioning pulmonary syst...
Oximetry
Oximetry (Oxygen Saturation, Oximetry, Ear Oximetry, Pulse Ox, Sp0 2 ) Procedure overview What is pulse oximetry? Pulse oximetry is a procedure used to measure the oxygen level (or oxygen saturation) in the blood. It is considered to be a noninvasive, painless, general indicator of oxygen delivery to the peripheral tissues (such as the finger, earlobe, or nose). How does pulse oximetry work? Oxygen in the air is breathed into the lungs. The oxygen then passes into the blood where the majority of the oxy...
Peak Flow Measurement
Peak Flow Measurement (Peak Flow Meter, PFM, Peak Expiratory Flow Measurement) Procedure overview What is peak flow measurement? Peak flow measurement is a procedure in which air flowing out of the lungs is measured. The measurement obtained is called the peak expiratory flow rate (PEFR), or peak expiratory flow (PEF). Peak flow measurement may be obtained using a spirometer, an instrument with a mouth piece that measures the amount of air breathed in and/or out and the rate at which the air is inhaled ...
What Is Bronchodilator Reversibility Testing?
What Is Bronchodilator Reversibility Testing? Bronchodilator reversibility testing is used to help your doctor assess your lung function after you have been given a type of lung medication called a bronchodilator. It's often used in people who have asthma or chronic obstructive pulmonary disease, or COPD. This test uses spirometry and a bronchodilator. You are given the drug to relax your breathing muscles so that you can breathe more easily. The amount of improvement in your breathing after taking the ...
Spirometers
Spirometers What is a spirometer? A spirometer is a device used by your doctor that assesses lung function. Click to Enlarge Spirometry, the evaluation of lung function with a spirometer, is one of the simplest, most common pulmonary function tests and may be necessary for any or all of the following reasons: To determine how well the lungs receive, hold, and utilize air To monitor a lung disease To monitor the effectiveness of treatment To determine the severity of a lung disease To determine whether t...
