RESUMEN
In April 2022,an epidemic occurred in Gongshu District,Hangzhou,where Zhejiang Cancer Hospital is loca-ted.And the hospital was confronted with the most extensive,the most unusual and the most urgent public health emergency crisis since its establishment.Taking patients as the core and proceeding from the public perspective,an authoritative voice of a hospital was conveyed in a timely and accurate manner,which demonstrated the hospital's resolution and executive power in the crisis.Based on Malcolm Gladwell's"tipping point"theory,the paper reveals the situation of online public opinion caused by the sudden epidemic and its response,discusses the hospital's communication practices in handling public health emergencies and provides hospitals with practical reference for brand promotion and operation.
RESUMEN
Objective To compare adaptive support ventilation (ASV) and pressure-controlled assist/control ventilation (PCMV) and evaluate the clinical effects of ASV. Methods 12 cases of acute respiratory failure patients induced by all causes were selected in the study. All patients with breathing independently underwent endotracheal intubation. The patterns of mechanical ventilation was PCMV-ASV-PCMV. the two settings of PCMV were uniformity. With ASV mode mechanical ventilation,we adjusted the percentage of minute ventilation (MV%) and ideal body weight (IBW) of patients,so as to reach the same minute ventilation volume of PCMV. We compared the blood gas,respiratory mechanics,work of breathing(WOB),airway occlusion pressure (P0.05). Compared with the first of PCMV,various indicators and blood gas of ASV had no significant difference,work of breathing (WOB),airway occlusion pressure (P=0.1) and inspiratory pressure time product (PTP) were significantly lower (P0.05). Conclusion ASV can get similar goals with conventional ventilation,and reduce patient′s effort and the central respiratory drive.
