Understand home ventilator

1. Basic working principle of ventilator

Inside the human chest is a negative pressure system. When the inhalation, the diaphragm decreases, the thoracic outlines expand outward, the internal gas pressure in the chest cavity is reduced, and the negative pressure makes the atmosphere inhale into the lungs.

When the function of the negative pressure system is lost or weakened, the pressure difference between the airway and the alveolar is reduced, resulting in ventilation disorders. The ventilator increases the external air pressure through mechanical drivers. The airway mouth pressure is greater than the alveolar air pressure. The air is blown into the chest cavity; the in vitro mechanical driver is removed, the thoracic and the lung elasticity are retracted, and the gas is eliminated from the lungs to assist the patient's ventilation.

During the breathing process of the human body, the ventilator can perform external respiratory and lung ventilation function, that is, the process of entering and leaving the alveolar in external air, which has a small impact on the internal respiratory, that is, the effect of the pulmonary capillaries and alveolar gas exchange is relatively small.


2. Advantages of using ventilator

The ventilator can increase lung ventilation and improve ventilation function. Patients do not need to use too much strength to breathe, thereby getting rest and helping to recover.

Home ventilator is a simple, effective, easy -to -accept non -invasive ventilation treatment. Its small volume, less painful intubation, convenient operation, reliable and safe, slow down the patient's condition, especially the cooperation of family members and patients, can effectively improve the curative effect and promote early recovery.

In short, the use of household non -invasive ventilator to treat family expenses and reduce the pressure of hospital beds. It should be promoted. I hope that this article will have a certain reference for patients and family members.


3. Application of household ventilator

Household ventilator is mainly suitable for restricted ventilation disorders, low ventilation at night, apytic sleep suspension, lung fibrosis, chronic obstructive pulmonary disease (COPD) stability period, infection inflammation, mild moderate respiratory failure, internal and external injuries and other patients. Essence When patients have severe symptoms, they still need to be diagnosed and cured by professional medical staff.

If you suddenly have unclear consciousness, poor breathing, unable to cooperate with ventilator breathing, poor airway protection, sputum cannot be discharged, vomiting, gastrointestinal bleeding, facial compression or trauma, hypotension, severe arrhythmia, etc. Dynamic disorders are non -invasive ventilation taboos and should be sent to the hospital in time.


4. The difference between household ventilator and medical ventilator

The medical ventilator can connect the oxygen source to regulate the oxygen concentration. There may be higher oxygen -giving speed, that is, at high flow to give oxygen, scour the upper respiratory tract, remove carbon dioxide and improve oxygen, and then continue the patient's life; home ventilator; It can only be hit into the air, generally low flow to give oxygen.

The medical ventilator can remove the secretions and sputum of the nose and nose by intubation. The home ventilator can only be passed through the nose and nose.

Mild patients can use household ventilator. Patients with severe illnesses are heavily hypoxic, shortness of breath, and constantly breathing to increase the positive oxygen input of the home ventilator, which is easy to make the lung gas too much and damage the lungs; the medical ventilator can calculate the calculation Patient's breathing time, pressure, etc., adapt to the patient's breathing and mechanical ventilation.
Therefore, the medical ventilator is equal to the upgraded version of the home ventilator, and many functions are not available in home ventilator. However, most of the time, the ventilator is cured and does not cure the root cause. For example, the new coronary pneumonia is due to the increased inflammatory storm that increases the endocrine of the alveolar, resulting in an internal respiratory disorders. Although the ventilator can be blown into more air to the lungs to improve the symptoms of hypoxia. Finally, the symptoms of hypoxia. It is also necessary to defeat the virus by the immune system and reduce lung end secretions to fundamentally solve the problem of hypoxia.
