Auto Alert Limits
Once the limit values are set, the user should periodically confirm patient status by alternate means
and not rely solely on alerts generated when a limit is violated.

and low limits. Those ranges are:
For example, if the average of the three most recent ETCO
was 32 mmHg, the upper alert limit is set to 40 (32 + 25% = 32 × 1.25 = 40) and the lower alert limit is
set to 24 (32 - 25% = 32 × 0.75 = 24). If the average ETCO
be set to 55 (45 + 10 = 55) and the lower limit would be set to 35 (45 - 10 = 35).

Respiratory Rate Auto Alert Limits

The respiratory rate auto alert limits are derived from the average of the three most recent respiratory rate
values recorded before
high and low limits. Those ranges are:
For example, if the average of the three most recent respiration rate values recorded before
pushed was 28 br/min, the upper alert limit is set to 38 (28 + 10 = 38) and the lower alert limit is set to
21 (28 - 7 = 21). If the average respiratory rate is 12 br/min, the upper limit would be set to 19 (12 + 7 =
19) and the lower limit would be set to 6 (12 - 50% = 12 × 0.50 = 6).
