ObjectiveTo evaluate the effect of high-frequency chest well oscillation expectoration system on ICU patients with invasive mechanical ventilation. MethodsA total of 96 patients stayed in ICU with invasive mechanical ventilation were divided into observation group and control group, 48 cases in each group. Mechanical vibration sputum expectoration was used in control group. High-frequency chest well oscillation expectoration system was used in observation group. The amount of sputum, vital signs, weaning time and ventilator-associated pneumonia (VAP) incidence were compared between the two groups. ResultsThe amount of sputum in observation group was significantly higher than that of control group, the difference was statistically significant(P＜0.05). After sputum excretion, the heart rate, breathing and systolic blood pressure of two groups were no statistically significance(P＞0.05). The blood oxygen saturation of observation group was significantly higher than that of the control group, the difference was statistically significant(P＜0.05). The weaning time of ventilator of observation group was significantly lower than that of the control group, the difference was statistically significant(P＜0.05). The VAP incidence of observation group was significantly lower than control group, the difference was statistically significant(P＜0.05). ConclusionHigh frequency chest wall oscillation sputum elimination system for ICU invasive mechanical ventilation patients with sputum drainage nursing, can effectively promote the discharge of sputum, improve blood oxygen saturation, shorten the withdrawal time, and could effectively prevent VAP.
