What is the function of a ventilator

A ventilator is a common piece of equipment in hospitals. Many people may not know what a ventilator can be used for. Generally speaking, a ventilator is only needed for some serious diseases. As the name suggests, a ventilator is used to assist breathing. Ventilators are generally available in most hospitals. They are mainly used for some critically ill patients to replace self-breathing. Ventilators can be used for treatment and emergency treatment. Avoid respiratory failure and save the patient's life. Some people may be concerned that ventilators will not have any side effects. In fact, apart from the high cost, there are almost no side effects of ventilators. So you can use it with confidence.

1. Treatment of respiratory failure

In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation function, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupy a very important position in the field of modern medicine. A ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.

2. The ventilator has the following functions :

⑴ Provide power to transport gas, replacing the work of human respiratory muscles; ⑵ Produce a certain respiratory rhythm, including respiratory rate and inhalation-expiration ratio, to replace the function of human respiratory center to control respiratory rhythm; ⑶ Provide appropriate tidal volume (VT) or minute ventilation (MV) to meet the needs of respiratory metabolism; ⑷ The supplied gas is preferably heated and humidified to replace the function of human nasal cavity, and can supply O2 amount higher than that contained in the atmosphere, so as to increase the concentration of inhaled O2 and improve oxygenation.

3. Ventilator side effects

In addition, side effects are relatively rare and ventilator therapy will not cause patients to become addicted. Many patients stop snoring and their sleep quality improves after using a ventilator. They feel more energetic during the day and have better memory. If the ventilator is stopped before the condition is alleviated or stabilized, the symptoms will reappear, so the ventilator must be worn for a long time. Patients are compliant with the use of ventilators. After long-term use, the required pressure will gradually decrease, and they can eventually be completely independent of ventilator treatment, so they will not become addicted.
