Table 6 Cardiorespiratory suppression during endoscopic retrograde cholangiopancreatography under moderate sedation n (%)

	Age≥80 yr	Age < 80 yr	P value
	(n = 102)	(n = 105)
Total	9 (8.8)	8 (7.6)	NS
Hypoxemia	2 (2.0)	2 (1.9)	NS
Bradycardia	4 (3.9)	4 (3.8)	NS
Hypotension	5 (4.9)	4 (3.8)	NS

Hypoxemia: Peripheral oxygen saturation (SpO2) below 90%; Bradycardia: Heart rate less than 45 beats per minutes; Hypotension: Systolic blood pressure below 80 mmHg; ERCP: Endoscopic retrograde cholangiopancreatography; NS: Not significant.
