The outer surface of the lung covers the pleura, and is divided into lobules of unequal volume by the middle of the pleura. There are brachiocephalic veins, trachea, and esophagus on the inner surface of the right lung apex of the household ventilator, the left common carotid artery, left subscapular artery, trachea, and esophagus on the inner surface of the left lung apex, and the anterior inner surface of the lung apex has a subscapular groove. Compressed by the subscapular artery. The diaphragm of the right lung base is adjacent to the right lobe of the liver, and the diaphragm of the left lung base is adjacent to the left lobe of the liver, the fundus of the stomach and the spleen. Household ventilator The negative pressure of the pleural cavity keeps the lungs in an inflated condition. For example, the pleura is damaged. Under the atmospheric pressure, the size of the lungs can be reduced to 1/3 of the normal size. The lung is an organ for gas exchange. It is located on both sides of the mediastinum in the thoracic cavity. It is divided into the left lung and the right lung.
◎The bottom of the lung: also called the diaphragm surface, located above the diaphragm. The pressure of the diaphragm forces the bottom of the lung to sink upwards and sink into a half-moon shape. Because the right lobe of the liver is higher, the sinking of the right lung is more superficial.

◎Mediastinum: It is in contact with the mediastinum, and due to the compression of the heart, a heart pressure mark that sinks down is formed. In contact, the heart pressure trace of the right lung is in contact with a small group of the front of the right atrial appendage, the front of the right atrium, the right side and the right ventricle. In addition, the left and right vagus nerve organs run behind the ipsilateral lung roots, and the left and right phrenic nerve organs and pericardial phrenic blood vessels run in front of the ipsilateral lung roots.

◎Lung apex: The upper end of the lung is bluntly called the apex of the lung, which is urgently attached to the top of the pleura. It goes up through the upper thoracic orifice and protrudes into the base of the neck, adjoining the internal organs in the upper mediastinum.

The general shape of the lung can be divided into: one tip, one bottom, two sides and three edges, that is, the upper lung apex, the lower lung base, the mediastinal surface on the inner side, the ribbed side on the outer side, and the ribs and the mediastinum. Connecting the front edge, the rear edge, the lower edge of the lung base, the rib surface and the mediastinal surface. The lungs with normal body function are flesh red, soft in texture, and rich in elasticity. As the age increases, the dust in the air is continuously inhaled and deposited in the lungs, and the color of the lungs gradually changes to dark red or dark gray. The bronchi and pulmonary blood vessels in the middle of the mediastinal plane are called hilar. The adult right hilum is 6714 mm long and 33 mm wide, and the left hilar is 6016 mm long and 3016 mm wide.

◎Rib surface: relatively protruding, because of the pressure of the ribs, the shallow groove formed obliquely is called the rib pressure mark. The first rib pressure mark on the top is the most significant, which can be used as the boundary line between the rib surface and the lung tip. The structure that enters and exits the hilum is wrapped in cartilage tissue called the lung root, which covers the main bronchus, pulmonary artery, pulmonary vein, bronchial arteries, nerve organs, lymphatic vessels, and lymph nodes. The length is about 10 mm. The lung root is located below the aortic arch, in front of the thoracic aorta, the right lung root is located behind the superior vena cava and right atrium, and below the atypical venous arch.

The non-invasive ventilator is provided in a physical form to provide breathing power to the lungs and exercise lung function. As a domestic high-end ventilator brand, micomme is mainly divided into snoring ventilator and chronic obstructive pulmonary disease(COPD) ventilator.
