Table 3

Numbers of threshold alarms regarding ART.S, ART.M, HR, and SpO₂ after each advisory alarm has been assessed as true or false. The percentages marked with * are the proportions of the individual true and false alarm rates to all alarms of the respective individual vital parameter.

true	735 (45%*)	215 (49%*)	481 (61%*)	219 (21%*)	1650 (42%)
false	908 (55%*)	228 (51%*)	309 (39%*)	846 (79%*)	2291 (58%)
