Product Description:

Lung capacity bite refers to a device used for lung capacity testing, also known as a lung function test bite. It is usually a plastic or rubber mouthpiece, which patients bite and place in the mouth to block the nasal cavity, and then measure lung capacity and respiratory function through breathing.

The main function of the lung capacity bite is to ensure that air only enters and exits through the oral cavity during the testing process, without passing through the nasal cavity. This can ensure that all respiratory gases pass through the same path when measuring lung capacity, thus obtaining accurate test results.

When conducting lung capacity tests, patients are usually asked to take deep breaths and place the lung capacity bite in their mouth, then exhale or inhale as hard as possible until the lungs are as full or empty as possible. The test results are usually recorded on indicators such as expiratory capacity, inspiratory capacity, and lung capacity to evaluate the patient’s lung function and respiratory condition.

Pulmonary capacity testing is commonly used to evaluate lung health status, diagnose respiratory diseases (such as asthma, chronic obstructive pulmonary disease, etc.), monitor disease progression, and evaluate treatment effectiveness. The use of lung capacity bite can ensure the accuracy and consistency of the test, as it can eliminate the influence of the nasal cavity on the test results and provide a standardized testing method.
