IIT Kharagpur developed an ICU-grade ventilator under the project name "Project Prana" to address the shortage of ventilators during the Covid-19 pandemic. The ventilator is a cost-effective and portable solution, designed to meet the needs of patients in critical care, particularly in resource-limited settings. Project Prana's ventilator is equipped with multiple modes of ventilation and can function continuously for long periods, making it suitable for use in both hospitals and makeshift medical facilities. This innovation demonstrates India's efforts to increase self-reliance in healthcare technology during the pandemic.
