How does a medical ventilator work?
Ventilator is able to replace, control or change people's normal physiological breathing, increased pulmonary ventilation, improve respiratory function, reduce work of breathing consumption, save cardiac reserve capacity of the device.

Ventilator is a can replace, control or change people's normal physiological breathing, increased pulmonary ventilation, improve respiratory function, reduce work of breathing consumption, save cardiac reserve capacity of the device. When infants and young children with acute respiratory failure, after aggressive conservative treatment fails, breathing weaken and phlegm and thick, expectoration difficult airway obstruction or atelectasis, consider endotracheal intubation and medical ventilator.
Ventilator must have four basic functions, namely lung inflation, inspiratory to expiratory conversion, exhaust gas and alveolar breath to inhale conversion, followed by ad infinitum. Therefore, there must be: ⑴ can provide gas transportation power, instead of the human respiratory muscle work; ⑵ can produce some respiratory rhythm, including respiratory rate and respiratory ratio, in lieu of the human respiratory function of the central nervous disposable respiratory rhythm; ⑶ can provide appropriate tidal volume (VT) or minute ventilation (MV), to meet the needs of respiratory metabolism; ⑷ best gas supplied through heating and humidification, instead of human nasal function, and can supply higher than atmospheric contained the amount of O2 to improve inhaled O2 concentration, improve oxygenation. Power Source: Available compressed gas powered (pneumatic) or motor as the driving force (electric) respiratory rate and respiratory ratio may also use pneumatic air control, electronically controlled electric, pneumatic and other types of electronic control, call the inspiratory phase of the switch, often in the inspiratory breathing loop at a predetermined pressure within reach after switching to exhalation (constant pressure type) or reaches a predetermined inspiratory capacity after switching to exhalation (constant volume), but are both modern ventilator above two forms.

Ventilator therapy, commonly used in patients with severe disease more complex, requiring more complete functionality, can be a variety of breathing patterns to accommodate the changing needs of the disease. The anesthesia ventilator is mainly used for anesthesia in patients, mostly without significant cardiopulmonary abnormalities, ventilator requirements, as long as the flexible volume, respiratory rate and respiratory ratio who can do IPPV, basically can be used.
