  • Prana ventilator will deliver respiratory gas to patient by automated compression of Ambu bag.
  • Svasta ventilator will work without electric power.
  • VaU is a low-cost ventilator similar to commercial high-end ventilators in use.
  • Shwaas oxygen cylinder is capable of supplying 10 litres of enriched oxygen per minute and is adequate for two patients at a time. It enhances oxygen gas content by selectively separating nitrogen gas from ambient air through Pressure Swing Adsorption (PSA). PSA is commonly used for production of oxygen from the air.
