Spirometry
Espirometría
What it means
Spirometry is a lung function test that measures airflow: a spirometry test measures how much air you breathe out and how fast you can blow air out of your lungs. By measuring how much air you exhale, and how quickly, it can evaluate a broad range of lung diseases. For the test you sit on a chair with a soft clip on your nose and place your lips tightly around a mouthpiece connected to a device called a spirometer. You are told to take a deep breath in and then blow it out into the mouthpiece as hard as you can. People who use inhaler medicines (bronchodilators) may need to stop for a period of time before testing, and the provider tells them when to stop. Some people may feel lightheaded from breathing hard.

Espirometría is a feminine noun; the Spanish dictionary labels it a medical term and defines it as the measurement of the breathing capacity of the lungs, capacidad respiratoria. MedlinePlus en español uses it with an article, una espirometría, and also writes una prueba de espirometría. Its encyclopedia article on lung function tests, Pruebas de la función pulmonar, lists Espirometría and Espirograma among its alternative names.
The device is el espirómetro, and the mouthpiece you breathe into is la boquilla. For the nose clip, the MedlinePlus en español encyclopedia says pinzas nasales, and the lab test page says una pinza suave en la nariz and also clip. Other words from those pages: exhalar (to breathe out), inspirar profundamente (to take a deep breath), soplar (to blow), and medicamentos con inhalador (broncodilatadores) for inhaler medicines.
