What’s the ventilator machine cost?

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 of medical ventilator;

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 able to provide appropriate tidal volume (VT) or minute ventilation (MV), to meet the needs of respiratory metabolism;

⑷ the supplied gas is preferably subjected to heating and humidification, instead of human nasal function, and to supply the higher the amount of O2 contained in the atmosphere to increase the concentration of O2 inhalation and 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, electric electronic control, electronically controlled pneumatic and other types of switching between calls and inhale often to inhale in breathing loop reaches a predetermined pressure 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 form.

Ventilator machine cost depends on different tpyes.
