Baby Cold - Check Temp Probe alarm patient safety

Alarm activates when baby's skin temperature drops below set temperature. Low priority alarm (blinking red light, intermittent tone, 12 min silence) at >1.0°C below set temp; high priority alarm (continuous tone, 5 min silence) at >2.0°C below set temp.

Ranked causes

1. Temperature probe improperly attached to baby's skin (common)

First check

Verify baby's skin temperature reading

Test point: Temperature display on warmer screen
Expected: Should not be >1.0°C below set temperature (low priority) or >2.0°C below set temperature (high priority)
