Dear all, I've been re-reading the specs and considering the "must have" 30 minutes backup battery.
The issue had been addressed for sure but in the all this coming and going of messages I might have missed out if the backup had been dealt with.
I realize that it cannot be a priority during this phase of testing and refining the essential stuff, but if this has to be taken on, someone here may find some time to addres it.

There is no formal requirement for a 30 mnute backup battery other than the UF CSSALT specifications, which are reasonable and even minimum in this respect to allow a patient to be moved from one location to another.

Enclosed is a draft battery life test protocol and the successful results of a battery test performed on April 8 2020 demonstrating the system easily runs at least 60 minutes.
Took a total of 4 hours to perform and document all of this.??

I like the idea of battery backup however for ventilators powered by hospital “house air supply” , if the patient is being moved then the compressed air / medical breathable air will be disconnected and the battery will be powering only the circuits and alarms which will be pinging away to notify pressure loss.

systems having independent blowers or bag squeezers won’t have this issue except for low oxygen alarm but you guys are all avoiding the expense of blowers to keep this system Swiss watch reliable with third world price ..and why not , that’s where lives will be saved.

Hopefully the software will have lines of code that can be enabled / disabled to activate inclusion of equipment such as servo motors or blowers at a later point.

i am aware that time is critical and none of us want delays in completion ?, backup battery is still useful in case of power outages with a fixed bed.
