The Smart Low Cost Ventilator | Intel DevMesh

The Smart Low Cost Ventilator Shriram KV Tiruchirappalli, Tamil Nadu 2 ... Mechanical ventilation is the process of supplying scheduled breaths to a patient who lacks the ability to do the Work of Breathing (WOB) himself/herself. The pattern of breathing for every patient is identified using sensor(s) and the required volume of air is supplied by compressing a Bag Valve Mask (BVM) device. A ...
