What is the standard normal lung function

First, the lung volume measurements (static lung capacity)
(1) tidal volume (VT): This refers to the quiet breathing, inhaled or exhaled gas each time.
normal reference values: 500ML (adult)
(2) make up the amount of suction (IRV): refers to the calm after the forced inhalation of the maximum inspiratory gas.
normal reference values: M (male): 2.16L or so F (female): 1.5L around
(3) expiratory reserve volume (ERV): refers to the calm after the forced expiratory volume exhaled maximum.
normal reference values: M (male): 0.9L or so F (female): 0.56L about
(4) residual volume (RV): To complement the breath, the lungs can not exhale the residual gas.
normal reference values: M (male): 1.380 +0.631 LF (female): 1.301 +0.466 L
(5) inspiratory capacity (IC): refers to the calm after the expiration of the maximum can be inhaled gas (tidal volume + fill inspiratory capacity).
(6) vital capacity (VC): maximum can be exhaled after a maximum inspiration (total) gas. (Inspiratory tidal volume + volume + expiratory fill volume) Knowledge of business and finance, please go to pregnancy
normal reference values: M (male): 3.5L so F (female): 2.4L about
(7) functional residual capacity (FRC): refers to the calm gas contained in the lungs after expiration (expiratory reserve volume + residual volume).
normal reference values: M (male): 2.77 +0.8 LF (female): 1.86 +0.5 L
pulmonary function test results help determine whether the ventilatory dysfunction, as well as the nature and extent of barriers, as Some lung disease diagnosis aids. Pulmonary function tests can also be an important indicator for judging the efficacy and evaluation to guide clinical treatment; thoracic surgery preoperative pulmonary function test to help determine the safety of surgery; labor hygiene and occupational diseases in the field can be used to understand the work environment on pulmonary function and labor identification. With the medical and other scientific and technological development, pulmonary function tests will become more popular and perfect to play a greater role.
arterial blood gas analysis is the detection of lung ventilation function of the major projects, key indicators include: blood pressure, arterial carbon dioxide pressure, pH, standard base, buffer base, base excess. Based on the above indicators can determine whether and the extent of hypoxia, with or without acid-base imbalance and the imbalance of the type, degree, etc., for surgery, anesthesia, critical care and emergency care provide an important basis.

pulmonary function tests is a completely non-invasive way to measure lung function. When lung lesions occur will cause the body's oxygen, causing damage to body organs, and by lung function examination, the doctor can understand the patient's lungs are normal or lung disease due to the extent of damage, so doctors to take advantage proactive approach to prevent further development of lesions, it is very important. The following pulmonary function tests the patient needs to be done:
