EC Full Form is Expiratory Capacity . Expiratory Capacity measures exhalation (removing waste gases from the lungs). Expiratory capacity measures the lung volume exhaled with maximum force, commonly given in litres of air exhaled in one second. Spirometry is used to measure, which is reported in milliliters (ml) or litres (L).
Definition of Expiratory Capacity
Expiratory capacity measures Exhalation (removing waste gases from the lungs). Expiratory capacity measures the lung volume exhaled with maximum force, commonly given in liters of air exhaled in one second. Spirometry measures volume, which is reported in milliliters (ml) or liters (L). Most people have a lower expiratory capacity than their life expectancy since they no longer breathe air instead of exhaling it. A person's risk of having pneumonia and other lung disorders is reduced with a larger expiratory capacity. Expiratory capacity can also be used to determine a patient's respiratory state. Spirometry measures lung storage capacity, ranging from 1 to 10 liters. During the test, milliliters are used to quantify ability and are recorded as an average.EC Full Form in English
EC Full Form in English is Expiratory Capacity. Expiratory Capacity, also known as Expiratory Vital Capacity (EVC), is the air a person can forcefully evacuate from their lungs after taking a deep breath. Expiratory capacity is the maximum amount of air an individual can exhale, given the duration and depth.
EC Full Form in Hindi
EC Full Form in Hindi is निःश्वसन क्षमता है। निःश्वसन क्षमता, जिसे निःश्वसन महत्वपूर्ण क्षमता (ईवीसी) के रूप में भी जाना जाता है, वह हवा है जिसे एक व्यक्ति गहरी सांस लेने के बाद अपने फेफड़ों से बलपूर्वक निकाल सकता है। यह किसी व्यक्ति के श्वसन कार्य का आकलन करने के लिए फुफ्फुसीय कार्य परीक्षण में उपयोग किए जाने वाले प्राथमिक मेट्रिक्स में से एक है।
EC Full Form in Medical
EC Full Form in Medical is Expiratory Capacity. Expiratory Capacity is an important metric used in pulmonary function tests to assess the efficiency and capacity of the respiratory system. Healthcare experts can learn a lot about a person's lungs by measuring how much air they can forcefully exhale after taking a deep breath.

Function of Expiratory Capacity
Expiratory capacity refers to a person's lungs' capability to exhale air. According to estimates, 80–90% of adults have lower expiratory capacities than their 60-year life expectancy. This is because most individuals now exhale air rather than breathe it in. More air may be expelled with a higher expiratory capacity, which lowers the risk of pneumonia and other lung conditions. Expiratory capacity can be used to determine a patient's respiratory state.
Significance of Expiratory Capacity
It is well recognized that those with poorer Expiratory capacity are more likely to develop respiratory disorders such as pneumonia, bronchitis, and asthma. However, the precise association between exhalation capacity and a person's illness state is unknown. The Causes of decreased Expiratory capacity are Heart disease, asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. The patient should be aware that they have lost expiratory capacity so that they can seek therapy if necessary.
Estimation of Expiratory Capacity
A physician or nurse performs a spirometry test to evaluate Expiratory capacity. The spirometry test determines an individual's lung function. The patient is instructed to exhale rapidly into a mouthpiece for approximately 6 seconds. The spirometer monitors the amount of air that leaves their lungs. The test simply compares forced exhalation to airway resistance (the barrier to airflow in and out of the lungs). The Lung elasticity and lung function are considered for calculating the person's lung capacity. This can also be done manually by timing how long it takes a person to breathe out as much as they can generally while fasting. A specific probe measures how long it takes to exhale as much as it can generally while the person's stomach and chest are palpated. This quantity can be translated into estimating the subject's expiratory volume in cubic centimeters (or liter-minutes) or the air the subject can exhale while at rest (as determined by the expiratory capacity).
