AUTOMATED VENTILATORS TO COMBAT COVID-19; 3RD APRIL 2020 CURRENT AFFAIRS

AUTOMATED VENTILATORS TO COMBAT COVID-19

Context: SCTIMST ties up with Wipro 3D to manufacture automated ventilators to meet COVID 19 related crisis.

ABOUT THE DEAL

Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST) is an institute of National Importance of the Department of Science and Technology. It has tied up with Wipro 3D, Bengaluru to jointly build up on a prototype of an emergency ventilator system.

This portotype will be based on Artificial Manual Breathing Unit (AMBU), developed by SCTIMST followed by its clinical trial and manufacture.

HOW THESE AUTOMATED VENTILATORS WILL HELP?

The ventilators can help meet urgent requirements arising out of the Covid 19 related crisis that the country is facing.

AMBU bag or a bag-valve-mask (BVM) is a hand-held device used to provide positive pressure ventilation to a patient who is either not breathing or who is breathing inadequately. However, the use of a regular AMBU needs a bystander for its operations who is highly susceptible and non-advisable to be in close contact with the COVID-19 patient.

Now, this portable and lightweight device enables positive pressure ventilation with a controlled rate of expiration, Inspiratory to Expiratory Ratio, Tidal Volume, etc.

Also, a PEEP (Positive End Expiratory Pressure) Valve can be added as an extra component to maintain pressure on the lower airways at the end of the breathing cycle, which prevents the alveoli from collapsing during expiration. 

The automatic device will minimize the need of support personnel in the isolation room, thereby enabling a safer and effective lung-protective operation to COVID patients.

WHAT ARE VENTILATORS?

ventilator is a machine that provides mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. 

Ventilators are chiefly used in intensive care medicinehome care, and emergency medicine (as standalone units) and in anesthesiology (as a component of an anesthesia machine).
