Spirometry and Pulmonary Function Testing in Enterprise, NV
Get clear answers about your breathing with advanced lung function testing.
Spirometry and pulmonary function testing are how physicians measure exactly how well your lungs move air, and for many Enterprise residents this test is the difference between guessing at a diagnosis and knowing what is actually happening in the airways. Chronic cough, wheezing, shortness of breath, or exercise intolerance can all point to asthma, reactive airway disease, or other conditions that spirometry can help clarify. Tottori Allergy and Asthma Associates has been serving Las Vegas since 1992 and offers in-office spirometry as a standard part of the asthma and lung workup.
Dr. David H. Tottori is board certified in Allergy and Immunology plus Pediatrics, so both children and adults can have accurate lung testing done in a single visit. Our West office on Cheyenne is a straightforward drive up the 215 Beltway from most Enterprise homes. Call 702.240.4233 to schedule, or request an appointment online to see current availability.

How Spirometry Measures Lung Function
Spirometry is a non-invasive breathing test that measures two important numbers: the total volume of air you can forcefully exhale in one second, known as FEV1, and the total amount of air you can exhale after taking a deep breath, known as FVC. The ratio of those two numbers tells the physician whether air is moving out of your lungs normally, or whether something is restricting flow, which is what happens in asthma.
During the test you sit upright, place a mouthpiece between your lips, take a deep breath in, and then exhale as hard and fast as possible for at least six seconds. Most patients repeat the maneuver three times to confirm consistent results. In some cases, the allergist gives you a bronchodilator like albuterol and then repeats the test 15 minutes later to see whether your numbers improve, which helps confirm reversible airway obstruction typical of asthma.
The results also help distinguish asthma from other conditions on the Tottori list of conditions we treat, including reactive airway disease, exercise-induced asthma, chronic cough, and vocal cord dysfunction. Objective numbers are more reliable than symptom reports alone, especially for children who may not describe their breathing changes accurately.
Services That Work Together for Respiratory Diagnosis
Spirometry is often paired with other services for a full picture:
- Pulmonary function testing with spirometry measures how well your lungs move air and how they respond to bronchodilator medication.
- Allergy skin testing identifies environmental triggers like dust mites, mold, and pollen that may be driving asthma symptoms.
- Immunotherapy allergy shots can reduce reactivity to allergens confirmed as asthma triggers over time.
- Food allergy testing is included when food-related reactions may be contributing to lower airway inflammation.
- The full listing of services shows how these diagnostics combine into a single treatment plan.
Signs You May Need Spirometry
Spirometry is often recommended when you notice:
- A cough that has lasted longer than eight weeks
- Wheezing or whistling sounds when you breathe
- Shortness of breath during ordinary activities or exercise
- A tight or heavy feeling in your chest that comes and goes
- Symptoms that get worse during Las Vegas dust storms or wildfire smoke days
- A family history of asthma or allergic rhinitis
- A rescue inhaler that seems less effective than it used to be
Why Choose Tottori Allergy for Spirometry

Diagnosing airway conditions is not just about running one test in isolation. It is about pairing spirometry with allergy skin testing, symptom history, and physical exam findings so the diagnosis is complete and the treatment plan is precise. Tottori Allergy runs all of these under one roof, which cuts down on referrals and repeated visits. That efficiency matters for Enterprise families whose kids may miss school for medical appointments, or working adults balancing appointments with commute time.
