Close the pipe section of gas.
Background technology
Lung ventilator is can to play auxiliary treatment respiratory failure, Breathing Suppotion treatment, the doctor for saving and extending patients ' lives
Treat equipment.The operation logic of lung ventilator is by a certain proportion of (compression) air and the lung that patient is delivered to after (compression) oxygen mix
Portion, and require that the sky of input, oxygen gas mixture need to meet with certain humidity and temperature, the i.e. gas of patient's incoming call
The tidal volume parameter request medically required.The moisture output quantity of lung ventilator must be more than the physiology tidal volume of people, physiology tide
Tolerance is 6-10 milliliters/kilogram, and the moisture output quantity of lung ventilator is up to 10-15 milliliters/kilogram, often physiology tidal volume
1 to 2 times, specifically also further to be adjusted according to chest rise, the lung air inlet situation of auscultation two, the table of reference pressure two, blood gas analysis etc.
