Abstract

Objective To compare the difference of impact on the nursing time consuming between two types of artificial airway humidification, which means HME (heal and mositure exchanger) and HH (heated humidifier).Methods Use HME as experimental group and HH as control group, evaluate the effect of these two types of artificial airway humidification from sputum viscosity, formation of sputum callus, airway spasm and humidification accident, account, and analyze the data by statistic method. Results HME was much better than HH on effect of humidification. The experiment group spent (6.67±1.01 ) min on time consuming for nursing and the control group spent (26.27±1.75) min, the difference between two types of humidification was significant (P < 0. 01) . By the way, HME was much better than HH on the frequency of sputum suction bedclothes replacement (P<0.05).Conclusions The advantage of HME is decreasing the nursing manpower investment, through saving the time consuming for nursing, relieving strength of nurse work and improving efficacy of artificial airway management. Key words: HME (heal and moisture exchanger); HH (heated humidifier); Nursing time consuming
