Under What Circumstances Are Invasive Ventilators Used?

      There are two types of ventilators: invasive and noninvasive. Generally speaking, invasive ventilators require tracheal intubation. Noninvasive ventilators generally use masks or nasal masks. Many patients' families will not understand why invasive ventilators are used when there is no invasive ventilators, but also tracheal intubation makes patients very painful. Both types of ventilators have advantages and disadvantages. It is necessary for us to choose a ventilator according to different circumstances. Although the non-invasive ventilator is convenient to use and the patient's pain is small, it has little support for breathing and can be used in a non-serious state. If the situation is serious, the patient will have difficulty breathing but also wear a mask and respiratory support is small, the patient will be very uncomfortable, leading to deterioration of the condition. For example, if the patient is in a delirious state, an invasive ventilator must be used. Because the non-invasive respirator covers the patient's mouth or nose, a critical situation can arise if the patient vomits and does not know to remove the mask during a coma. Therefore, the use of non-invasive ventilators is not recommended for comatose patients and cases of respiratory failure. 

     In the case of invasive ventilator, it can protect the airway, even after vomiting, it can not breathe into the lungs, reducing some of the trouble of later treatment. Therefore, according to different diseases and patients, the use conditions of the two ventilators will be different.
