| Microprocessor based Ventilators |
In a microprocessor based ventilator, the microprocessor will assist for ventilation. A gas consumption meter is attached to the microprocessor . This unit will monitor the patient’s ability to breath naturally by monitoring the gas consumption. If the gas consumption is low it indicates that the patient is unable to breath himself. So if the gasconsumption degrades below a desired value, this unit will issue control signals to the micrprocessor. The micrprocessor in turn issue trigger signals to the servo ventilator which is connected to the patient. Lung machine is also connected to the patient to measure various respiration parameters. If the parameters measured are not satisfactory enough, the lung machine unit can also trigger the microprocessor to activate servo ventilator.
