ABSTRACT
Objective To study clinical switching time of sequential mechanical ventilation on patients with chronic obstructive pulmonary disease with type Ⅱ respiratory failure.Methods The clinical data and laboratory data of 56 patients with chronic obstructive pulmonary disease combined with type Ⅱ respiratory failure,According to treatment intervention,56 cases were divided into the observation group and control group,each group with 28 cases,all adopted invasive mechanical ventilation patients,the control group adopted the trachea intubation and mechanical ventilation treatment;The observation group was the sequence through air treatment,The clinical effect of two groups was compared.Results The time of invasive mechanical ventilation in the observation group was (3.2 ± 0.9) d,the control group was (20.2 ± 1.6) d,the total length of hospital stay in the observation group was (13.6 ± 2.5) d,the control group was (27.6 ± 11.3) d,the cost in the observation group was (12 654.2 ± 1 654.7) yuan,the control group was (29 658.9 ± 3 654.2)yuan,the observation group was better than that of the control group,with statistical significance(P ＜ 0.05);The cure rates of the observation group was 89.29％,which was higher than 71.43％ of the control group (x2 =6.34,P ＜ 0.05).Conclusion Sequential mechanical ventilation in patients with chronic obstructive pulmonary disease with type Ⅱ respiratory failure of clinical switching time is the key factor for treatment,can achieve good treatment effect,reduce the incidence of pneumonia,which is worthy of clinical promotion and further study.
