Abstract: Objective To study the effect of different ways of oxygen inhalation in preventing hypoxemia in pulmonary resection patients during transportation process． Methods Sixty pulmonary resection patients adm itted to post-anesthetic ICU (PACU) from June 2013 to November 2013 were divided into two groups, which were continuous oxygen inhalation group (C group, continuous administration of low fow oxygen via oxygen pillow) and non-continuous oxygen inhalation group (NC group, high oxygen fow of 6 L/min for 5 minutes administration of oxygen via nasal catheter before transportation process), 30 in each group． Changes of SpO₂ were observed． Results SpO₂ of C group decreased signif cantly than that of NC group． Compared with NC group, C group showed lower incidence of hypoxem ia． Conclusion Continuous adm inistration of low fow oxygen via oxygen pillow can prevent hypoxem ia after pulmonary lobectomy during transporting back to ward, which is easy to operate and be accepted by nurses and patients．
