Sensor check and diluent warning
Posted: Wednesday 8. February 2023, 11:42
Hi.
I've done one simulation in my OSTC plus in CCR mode. Data:
Dil NX32
B/O NX30
SP 1.3
I realize a couple of details:
1- At 30m. I have a diluent warning ppO2 1.25. This warning tells me that if I would flush with my diluent now or breathe it OC, the ppO2 value would be too high or too low. Questions:
- How much does this measure have to deviate, from the current established SP 1.3, to get a diluent warning? In this case it deviates 0.05
- How is this value of 1.25 ppO2 Dil calculated? In my calculations it would be ppO2= 0.32*4= 1.28
- In case of B/O ppO2 values also don't match the formula ppO2= FO2 * PT (ATA)
2- In the sensor check selectable information I have a ppO2 Dil 1.25 and a ppO2 O2 3.91. These ishows the possible ppO2 values in case I would flush with the diluent or with O2 at that moment. Question:
- As in the previous case, I don't understand the resulting values. In my calculations it would be ppO2 dil= 0.32*4= 1.28 and ppO2 O2= 1*4= 4
I hope you can solve these doubts.
