Abstract
Objective To investigate the effect of continuous heated humidification on critical patients with artificial airway. Methods 60 patients with artificial airway were randomly divided into experimental group and control group, 30 cases each group. Experimental group received continuous heated humidification and control group used artificial nose to humidify airway. To compare sputum viscidity, sputum scab, amyctic cough, respiration mucosa bleeding of two groups. Results There were significant differences between the two groups in sputum viscidity, sputum scab, amyctic cough, respiration mucosa bleeding (P ＜ 0. 05). Conclusions Continuous heated humidification can bring much better effects to patients than hygroscopic condenser humidifier.
