From: Retrospective analysis of pulse oximeter alarm settings in an intensive care unit patient population
Consistency of high alarm rates. The percentage of patient records having X percent of 3 h segments with alarm rates ≥ 1 alarm/h, for patient records with a minimum of 12 h of SpO2 data. For example, 55 % of patient records have at least 20 % of segments with an alarm rate of ≥ 1 alarm/h at the alarm setting of 90 %–15s. At 84 %–45s only 23 % of all records have at least 20 % of segments with an alarm rate of ≥ 1 alarm/h
