[Retracted] The Impact of Noninvasive Ventilator Assisted Ventilation Nursing Combined with Mechanical Vibration on the Level of Heart Failure Indexes in ICU Patients with Acute Heart Failure

Table 3

Comparison of heart rate, blood pressure, and central venous pressure in the two groups ( ± s).

Index	Treatment group (n = 60)		Experimental group (n = 60)
	Before intervention	Postintervention	Before intervention	Postintervention
Heart rate (times/min)	119.85 ± 12.41	101.11 ± 10.25①	121.14 ± 11.52	89.52 ± 8.14①②
Systolic pressure (mmHg)	125.01 ± 3.45	104.12 ± 3.95①	124.94 ± 3.85	116.05 ± 4.11①②
Systolic pressure (mmHg)	78.69 ± 5.11	62.85 ± 4.11①	78.41 ± 4.95	68.18 ± 4.13①②
Central venous pressure (mmHg)	15.45 ± 2.52	8.14 ± 1.41①	15.48 ± 2.49	9.41 ± 1.29①②

Note:  < 0.05 was compared before intervention with this group, and  < 0.05 was compared with the control group.
