ABSTRACT
Objective To investigate the clinic application of venturi oxygen therapy heated humidify system on artificial airway management. Methods 30 cases of experimental group used venturi oxygen therapy for humidification and heating, while 30 cases of control group were treated with continuous wet micro-injection pump method for artificial airway care. Humidifying effects, effects of oxygen therapy, incidence of pulmonary complications were compared between the two groups. Results The humidifying effects on experimental group (26 cases) were better than control group (17 cases) (χ2=6.648,P<0.05). The irritating cough (5 cases), airway mucosa injury (1 case) and the formation of sputum crust (2 cases) in experimental group were less than 13 cases, 6 cases, 6 cases in control group (χ2=5.079, 4.043, 7.954,P<0.05). The times of sputum drainage on experimental group was (17.28 ± 5.51) times which was less than (31.22±5.24) times of control group (t=4.312, P<0.01).The effect on oxygen therapy about oxygen saturation in experimental group was 0.932 2 ±0.020 5 when sputum drainage, and 0.982 2± 0.009 4 two minutes later, which was higher than 0.916 7 ±0.011 2 and 0.957 2 ±0.013 6 of control group (t=3.431,6.276, P<0.01). Conclusions Venturi oxygen therapy heated humidify system can reduce the formation of sputum crust, reduce the times of sputum drainage, reduce hypoxia degree and shorten the duration caused by sputum crust, improve the effect of heat and humidification of patient.
