Medical air compressor for ventilators

Medical air compressor for ventilator is a place of control or change people's normal physiological breathing, increased pulmonary ventilation, improve respiratory function, reduce the work of breathing consumption, saving cardiac reserve capacity of the medical device. When infants and young children with acute respiratory failure, invalid after positive conservative treatment, decreased respiration and phlegm and thick, difficult expectoration, you should consider intubation and ventilator airway obstruction or atelectasis.

Medical ventilator must have four basic functions, namely lung inflation, inspiratory to expiratory conversion discharged alveolar gas and breath to inhale conversion, followed by the cycle. Therefore must have: (3) can provide ⑴ gas transportation power, instead of the human respiratory muscle work; (2) can have some breathing rhythm, respiratory rate and inspiratory to expiratory ratio, instead of the human respiratory function of the central nervous disposable respiratory rhythm; a suitable tidal volume (VT) or minute ventilation (MV), to meet the needs of the respiratory metabolism; (4) the supply of gas is preferably contained in the atmosphere after heating and wet, instead of human nasal function, and can supply higher than the the amount of O2, in order to improve the inhaled O2 concentration, improve oxygenation. Power source: available compressed gas powered (pneumatic) or motor as a power (electric) respiratory rate and respiratory ratio can also take advantage of the type of pneumatic air control, electric power control, pneumatic and electrical control, call inspiration switched with each other, often inspiratory reaches a predetermined pressure in the breathing circuit switched to breath (constant pressure) or suction switch reaches a predetermined capacity breath (constant volume), but modern ventilator both the above two form.
