Comparison of blood gas analysis indexes between two groups.

Groups		SaO2 (%)		PaO2 (mmHg)		PaCO2 (mmHg)
		Before intervention	7 days after intervention	Before intervention	7 days after intervention	Before intervention	7 days after intervention
Observation group	92		^#		^#		^#
Control group	91		^#		^#		^#

^# vs. before intervention. SaO2: arterial oxygen saturation; PaO2: partial pressure of oxygen; PaCO2: partial pressure of carbon dioxide.
