IIT-R scientists develop low-cost portable ventilator

Researchers at the Indian Institute of Technology (IIT)-Roorkee, has developed a low-cost portable ventilator in collaboration with All India Institute of Medical Science (AIIMS), Rishikesh, owing to the increased need for ventilators for COVID-19 patients.

The closed-loop ventilator named Prana Vayu does not require compressed air for its working and hence can be useful when open wards are converted to ICUs, said an IIT-R statement to media.

The ventilator is equipped with real-time spirometry and alarms and it can automatically limit high pressure with an alarm system. In case of a failure, the circuit opens to the atmosphere which prevents choking.

Some of the features of the ventilator are remote monitoring by health professionals, touch screen control of all operating parameters, moister, and temperature control for inhaled air, said the IIT.

The ventilator is expected to cost ₹25,000 per unit and will be useful for a wide degree of congestions in the respiratory tract and is applicable for all age group patients, especially the elderly.

“It has been designed especially for COVID-19 pandemic. It is low-cost, safe, reliable, and can be quickly manufactured. We have successfully achieved the ventilator requirement on a test lung, and it can be used for both infants and even overweight adults,” said Akshay Dvivedi, one of the creators of the product.

The prototype was tested successfully for normal and patient-specific breathing conditions, the IIT said, adding that it does not require compressed air for functioning and can be especially useful in cases when hospital wards or open areas are converted into ICUs.

“Prana Vayu was presented to more than 450 industries representatives in a webinar organized by Confederation of Indian Industries (CII). I am happy to share that we have received interest from multiple industries for its mass production,” said Ajit K. Chaturvedi, director, IIT-Roorkee.

“This low-cost ventilator will be highly useful for COVID-19 patients, especially when there is a shortage of ventilators,” Chaturvedi added.
