This is a black testing report we host for developers to fill out when they are proposing updating the code on master.

Test Evaluator: G. Gibby

Item	Description	Result	Comment
1.	Software being evaluated. Include version, author, date,	Version 109Ashhar1.0/Gibby0429
2	Compile outcome	Small number of warnings for variables not utilized	No errors of any kind.
3	% of program space	22536=73% of space	Plenty of room.
4	% of dynamic memory	1049 = 51% , 999 free	Plenty of room.
5	Zero’ing of airway pressure sensor	Yes, announced by dot dot dash tones ending in 1000 Hzdash	Can be rezeroed with menu option at will
6	Zero’ing of flow measurement system	Yes, same as (5)
7	Ability to re-zero during later operation	Yes, with tones supported
8	Protection from accidentally turning Ventilator OFF	(battery backup) – two step process requires confirmationin menu structure
9	Display of Chosen Respiratory Rate	YES - “ticker”
9B	RR selectable	YES – menu item
10	Display of Chosen I:E Ratio	YES - ticker
10B	I:E at least 1:1 1:2 1:3	YES 1:1,2,3,4
11	Display of Chosen Peak Pressure Limit	YES - ticker
12	Display of Chosen Flow Limits(upper lower or otherwise)	YES – center in ticker
13	Display of airway pressure observed	YES - 1st line of display
13B	Display of PEEP	Chosen – ticker Observed – see 1st line
14	Display of flow measured	Volume displayed first line
15	Low pressure alarm	YES – checked
16	High Pressure alarm	YES – checked
17	Stop inspiration at high pressure alarm	YES – checked
18	Open expiratory valve at high pressure alarm	YES – verified
19	Alarm for low flow volume	YES - verified
20	Alarm for high flow volume	YES - verified
21-29 Reserved
30	Alarm Temporary Silence	YES – initiate menu
31	Inspiratory Pause Enable	YES - verified
32	Inspiratory Pause Disable	YES - verified
33	Assist Ventilation Enable	YES (when insp pause off)
34	Assist Ventilation Disable	YES (when insp pause ON)
35	Trigger for Assist Ventilation	Adjustable false triggered at 3cmworked at 4 cmmax value 15 below set peep value
36	Delay from trigger to effective inspiratory assistance	Virtually instantaneous
40	Failure if button held down	NO
41	Outcome of random simultaneous button presses	Expected actions
42	Outcome of pulling power	(no battery on my prototype; previously checked, no impact)
43	Outcome of pulling BMP280 clock line	Switches into open-loop mode with tone on each inspiration.
44	Outcome of pulling BMP280 data line	On 1st try – inspiration continued without stopping –system “hung”. Had to de-powerRepeated two more times, coutd not repeat. System switches to open loop mode with short dit at start of each breath.	We will be dependent on the mechanical overpressure if the I2C bus failure causes the processor to hang.....There is nothing code can do....when the processor is hung. Until the watchdog timer would intervene and the pressure would have to be controlled by mechanical means until then. This is the ONLY time I have ever seen this in many many tests (estimate >20) but it did happen!
45	Outcome of pulling BMP280 Vin line	Switched to open loop mode with beep on each inspiration
46	Function of ventilator with missing BMP280glue (cold start)	Open loop mode with beep on each inspiration	Note PEEP isn’t possibe.
47	Technique to re-enable BMP280	Menu operation, results in dit-dit-DASH to notify and screen display. Then restart Vent (menu operation)
48	Outcome of attempting to re-enable BMP	Works flawlessly
49-50 Reserved
50	Measured RR @ setting 10	10.0	While providing 10 cm peep
51	Measured RR @ setting 30	30.0	While providing 10 cm peep
52	Measure of idle time of processor	(Done in previous tests: making four total I2c calls, the fast portion of expiratory limb is doing all four in approximately 23 milliseconds.
53	Active PEEP
54	Assist Vent
