Common 6 modes of ventilator

Common 6 modes of ventilator: IPPV, CPAP, VSV, IMV, IRV, BI-PAP.

1. In modern clinical medicine, the ventilator, as an effective means to artificially replace the autonomous ventilation function, has been commonly used for respiratory failure caused by various reasons, anesthesia breathing management during major operations, respiratory support treatment and emergency recovery It occupies a very important position in the field of modern medicine. The ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the lives of patients.
2. (IPPV): This mode, regardless of the patient’s spontaneous breathing, will deliver air to the patient’s airway according to the preset ventilation pressure. When the airway reaches the predetermined pressure, the ventilator stops delivering air and passes through the chest and lungs. The exhaled air is the IPPV continuous positive airway pressure (CPAP), (PSV), (VSV): the ventilator presses the preset airway pressure or ventilation value, and then when the patient breathes in spontaneously , Provide support for ventilation pressure or tidal volume to ensure adequate ventilation. (IMV) and (SIMV): Based on the set ventilation mode, the ventilator intermittently injects a larger volume of gas as required to achieve the purpose of increasing ventilation. (IRV): In a breathing cycle, the inhalation time is greater than the expiration time. (Bi-PAP): Set a certain resistance in the airway when exhaling, so that the airway is continuously at a low level of positive pressure.
3. The applicable population of the ventilator is for; snoring crowd, sleep apnea, CSAS, MSAS, COPD, etc. The main reasons are often obese, abnormal nose development, hypertrophy and thick pharynx, uvula obstructed passage, tonsil hypertrophy, abnormal thyroid function, giant tongue, congenital micrognathia, etc., which is the upper respiratory airway Abnormal changes in the structure of the patient caused apnea. There are also patients with diseases of the central nervous system. Its symptoms include cerebral arteriosclerosis, cerebral infarction, brain tumors, brain inflammation, polio inflammation, cerebral hemorrhage, and head trauma. There are also respiratory muscle weakness, myasthenia gravis, etc., which can cause apnea. Differences Medical ventilators are mainly used in hospitals, with complex functions and suitable for various conditions. There are two types of household ventilators: one is to use a simplified version of the medical ventilator in the home, and the other is a non-invasive ventilator. The choice of the two ventilators depends on the condition. The original purpose of the non-invasive ventilator is to treat sleep apnea (patients with severe snoring). The purpose is more professional. Medical ventilator is suitable for various conditions.
