HR

The HR field is used to collect a patient's heart rate.

The unit used is beats per minute. Select which ever value gives you the highest score. When in atrial fibrillation, do not use this rate, use the ventricular rate.

Refer to General Collection Guidelines for Apache II#When to collect, which value to use for how and when to collect this.
