Technology Transfer of Centrifugal Blower based Critical Care Ventilator- 'VaU' (Interest Exploration Note) Home / Programmes/Technology Transfer /Technology Transfer / Centrifugal Blower based Critical Care Ventilator- 'VaU''
VSSC/ISRO has developed an ICU grade positive pressure mechanical ventilator titled 'VaU' ((वायु)), (abbreviation of Ventilation assist Unit), which can assist or replace the spontaneous breathing in patients under respiratory distress.
VaU is based on a centrifugal blower which draws in filtered ambient air, compresses it and delivers it to the patient to achieve ventilation and can therefore operate without a compressed pneumatic source. Provision is also given in the ventilator to connect a high pressure oxygen source, from which oxygen is metered automatically, to achieve the desired oxygen concentration (FiO2) in the inspiratory flow. Microcontroller based control module in the ventilator acquires signals from an array of sensors and commands the electro-pneumatic components to effect closed loop control.
More Details
VaU also comes with an intuitive Human Machine Interface (HMI) System running on a medical grade touch screen PC, which allows the operator to set and monitor various ventilation parameters in real time. A power supply unit, which can operate with 230VAC or an internal battery pack, is used to power the electro-pneumatic components, controller, and the HMI system of the ventilator. VaU has been configured to operate in a variety of patient/ventilator triggered invasive and non-invasive ventilation modes and has provisions to detect fault conditions and raise alarms through the HMI system to alert the operator.
