What is a pulmonary function test?

The effectiveness of the lungs is determined by a pulmonary function test. The test evaluates lung volume, capacity, gas exchange, and rate of flow, as well as other lung-related characteristics. Your doctor may be able to identify and treat some lung diseases based on the results.

How are pulmonary function tests performed?

Pulmonary function tests can be performed in two ways, depending on the information your doctor needs. In some cases, your doctor may request both tests since they measure different things. To evaluate your breathing, your doctor may use a spirometer (a device with a mouthpiece) or have you stand inside an air-tight box that resembles a telephone booth.

What does a pulmonary function test measure?

A pulmonary function test evaluates several elements of lung health. Here are a few examples:The volume of the lungs when they are entirely full of air is known as total lung capacity.The amount of air you can forcefully expel once your lungs have been completely filled is known as forced vital capacity.After you've expelled as much as you can, the amount of air left in your lungs.Functional residual capacity is the quantity of air left in your lungs after you typically exhale.

I went in with breathing issues they took me back immediately and started testing to find what was going on. I had pneumonia which I had asked my Doctor if he thought it was that at my appointment. I have been there several times and have been satisfied with the services. BEST urgent care in the area.

Everyone from the receptionist, the tech, the NP and the xray tech were kind, courteous, efficient, knowledgeable and thorough. I felt I received better care than at my family doctor.

I was totally impressed with the care I received at TAUC, Affton. After I had a very thorough checkup and an x-ray taken, the NP determined I had bronchitis. She put me on a nebulizer, and prescribed an antibiotic, a couple cough suppressants, as well as cough medicine. After my visit last Friday, and giving the meds a chance to "kick in", I feel much better today (Monday). I highly recommend TAUC to everyone!

In a recent emergency, my wife needed medical help quickly. I usually trust hospitals above urgent care centers but I was proven wrong when we opted for the closer Total Access in Wentzville. We walked in and she was immediately led to a private room and testing began right away. Tests performed were far more comprehensive than I would've ever guessed. The staff was super friendly and highly professional and calmed us down quickly. Top notch staff and state of the art equipment. We discovered that we made the right choice by coming here for healthcare. This is a great alternative to hospitals, where long waits and checking in before being seen is the norm. I'm recommending this option to anyone needing healthcare, especially friends and family. You want only the best in an emergency, and you can feel confident that you're getting exactly THAT here.

This is our first stop for our family’s urgent health care needs. We have been there three times in the last 18 months with our elderly father. Each time we have received a diagnosis that was accurate with the appropriate treatment and follow-up recommended. It is clean and bright and the staff has is very efficient with managing the process. Everyone we have ever seen has been kind and thorough in their assessment and explanations. I highly recommend this location for urgent care needs.
