Expiratory Power of the Lungs

Expiratory lung power (Emax) is an indicator of the state of external respiration. It is defined as the air pressure in the respiratory system during exhalation, when the nose and mouth are closed and the muscles that perform exhalation are maximally tense. Emax is expressed in millimeters of mercury (mmHg).

It is important to note that expiratory power may be altered in people with various respiratory diseases such as asthma, emphysema, chronic bronchitis and others. In such cases, Emax may be lower than normal, which may indicate problems in the respiratory system.

To measure the expiratory power of the lungs, special devices are used, such as a spirometer and a peak flow meter. They allow you to determine Emax and assess the condition of the patient’s respiratory system.

Measuring the expiratory power of the lungs is important for the diagnosis and treatment of various respiratory diseases. It can also help assess the effectiveness of treatment and predict possible complications.

Thus, the expiratory power of the lungs is an important indicator that allows you to assess the condition of the respiratory system and helps in the diagnosis and treatment of various diseases.

Expiratory lung power (EPL) is an indicator of the state of external respiration. It is defined as the air pressure in the respiratory system during the exhalation phase at maximum tension of the muscles that perform exhalation. EML is expressed in millimeters of mercury and can be used to assess lung function in various diseases, as well as to monitor patients undergoing treatment for lung diseases.

Under normal conditions, EML is around 50 millimeters of mercury (mmHg) and can fluctuate depending on a person's age, gender and fitness. However, in lung diseases such as chronic obstructive pulmonary disease (COPD), EML may be reduced. COPD is one of the most common lung diseases, which is characterized by difficulty in exhaling and decreased lung function. In COPD, EML usually decreases to 20-30 mm Hg. Art. and lower, which can lead to the development of shortness of breath and other symptoms.

EML is measured using a special device - an expiratory spirometer. This device measures the air pressure in the lungs during exhalation, which allows one to evaluate lung function and determine the need for treatment.

EML assessment can also be used to monitor patients during the recovery phase after treatment for lung diseases. For example, after a course of treatment for COPD, EML may increase to normal values, indicating restoration of lung function.

In general, expiratory lung capacity is an important indicator of lung health and can be used to diagnose and monitor lung diseases and evaluate the effectiveness of treatment.
