Table 2

Comparison of the two groups of respiratory indicators ( ± s).

Index	Treatment group (n = 60)		Experimental group (n = 60)
	Before intervention	Postintervention	Before intervention	Postintervention
PaO2 (mmHg)	48.58 ± 8.11	59.63 ± 6.85①	19.05 ± 7.53	68.25 ± 5.81①②
PaCO2 (mmHg)	72.01 ± 5.88	52.12 ± 4.61①	70.98 ± 6.04	42.11 ± 4.08①②
SpO2 (%)	75.85 ± 4.85	86.96 ± 4.01①	74.98 ± 4.96	94.78 ± 3.11①②
RR (times/min)	30.12 ± 3.05	21.55 ± 2.51①	29.89 ± 3.24	18.85 ± 1.74①②

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