The diagnostic accuracy of inferior vena cava respiratory variation in predicting volume responsiveness in patients under different breathing status following abdominal surgery

Table 1 The demographic and clinical characteristics of patients

Respiration mode	Group	N	Sex (Male/Female)	Age (yr)	BSA (m²)	ASA (II/III)	Type of surgery (G/H/P)
Mechanical ventilation	R	33	21/12	56 ± 8	1.64 ± 0.17	17/16	17/12/4
Mechanical ventilation	NR	23	10/13	58 ± 8	1.59 ± 0.20	12/11	12/8/3
Spontaneous breathing	R	22	11/11	58 ± 9	1.65 ± 0.13	10/12	10/8/4
Spontaneous breathing	NR	34	20/14	57 ± 8	1.61 ± 0.21	19/15	19/12/3

There was no statistical difference in basic data between the two groups in both mechanically ventilation and spontaneously breathing patients (p > 0.05)
