I work as a technician in a medical simulation lab (it's a fake hospital, with all the amenities, plus a central control room where we control and film everything), and one issue that we often run into is students will put oxygen on a patient or mannequin but won't verbalize the flow rate they've set it at. Normally this isn't a problem because the scenario simply requires them to give the patient oxygen, and not how much, but occasionally we run scenarios that require a certain amount (either at least x liters/minute, or no more than x liters/minute).
So, what I want to do is build a flow meter that can plug directly into the christmas tree
on the wall, not restrict the air flow at all, and allow the student to plug into a christmas tree on the device. The device would then connect to a server (probably via the Wifi Shield board), and send the flow rate to a listening app in the control room.
Does that make sense?
So, I've been browsing the forums for a bit and I can't seem to find a reliable small
airflow meter, and I was wondering if any of you know of one or how to build one. Also, beside the mainboard, wifi, and the flow meter, is there anything else you would think I need?
