Clinical predictors for hypovolemia	Mean ± SD	t value	p value
Respiratory rate (breath/min)	28.4 ± 7.6	4.3	<0.001
Heart rate (beats/min)	107.6 ± 7.9	18.0	<0.001
Systolic blood pressure (mmHg)	74.0 ± 6.5	18.5	<0.001
Diastolic blood pressure (mmHg)	44.1 ± 15.6	14.2	<0.001
Mean arterial blood pressure (mmHg)	53.9 ± 15.9	15.8	<0.001
