Threshold values for alarming mechanism.

Sinus rhythm type	Threshold value of heart rate, blood pressure, and temperature
Normal	60 ≤ HR ≤ 100 (beats/minute), BP = 100–140/60–80 mmHg, and temperature = 36.5–37.5°C
Bradycardia	HR ≤ 60 (beats/minute)
Tachycardia	HR ≥ 100 (beats/minute)
Hypertension (Stage 1)	Blood pressure = Sys/Dys ≥ 140/90 mmHg
Hypertension (Stage 2)	Blood pressure = Sys/Dys ≥ 150/95 mmHg
Hypotension	Blood pressure = Sys/Dys ≤ 90/60 mmHg
Fever	Temperature ≥ 37.8°C
Hypothermia	Temperature ≤ 35.0°C
