There is big hype in media on the demo, but I wish state that it is no more than a School Project as demonstrated. With Mahindra Power and Money, certainly, the organization should have attempted in a better level.

Let me comment on the clinical issues of the device:

- Single tube ventilation is used in the demo. This increases dead space multifold and hence CO2 clearance will be an issue. If CO2 clearance is impaired what is the use of Ventilation. In any Ventilator this is overcome by dual tubes – one for inhalation and another for exhalation. In Ambu Bags there is no tubing as it is direct mouth application.

- Long tube increases the airway resistance and hence the breathing dynamics changes.

- Variable Tidal volume is a must as different patients will have different lung capacity. There seems to be two levels only selectable which will not be enough to cater wide variety of patients. In the case of Ambu Bag, Physician using it has a Biofeedback. The users presses up to the needs of the patient. Also purpose of Ambu bag is only very short term till Ventilator is hooked up.

- There is no provision for adding Oxygen which will be required in any respiratory distress.

And much more can be said. How this will be used on critically ill? Big question if the authorities allows it to be used without proper audit on clinical aspects.
