AMBU BAGS

Director of the Indian Institute of Technology – Hyderabad (IIT-Hyderabad), has urged the government to consider the use of ‘bag valve masks’ as an alternative to meet any surge in demand for ventilators, in the wake of the COVID-19 pandemic.





About:

  1. ‘Bag valve masks’ are small devices used to deliver breathing support in emergency situations. They are also known as “ambu bags”.

  2. ‘Bag valve masks’ are currently hand-powered and therefore not suitable for continuous use as a ventilator. But this could easily be remedied by designing similar devices powered by an electrical source, which could be a car battery or conventional power supply.

  3. The devices would be made portable, and therefore easy to use in villages and other areas without power supply and could be manufactured in bulk quite inexpensively.

  4. IIT-Hyderabad scientists say the low-cost devices need to be manufactured on a war footing under the monitoring of a government task force

  5. Conventional ventilators are generally expensive, hard to produce and not portable.
