The problem of ventilation arrest in the use of portable type respirators

There were 22 ventilation arrest cases in incident reports in the Tokushima Hospital over nine years. The ventilation arrests occurred with all models used at the hospital, and were not limited to a specific model. The main causes were the deterioration of the parts (27.3%) due to age, and initial defectiveness of the programs (18.2%). Five ventilation arrests occurred with a change of the power supply (22.7%). Fortunately, no ventilation arrest has led to a medical error in our hospital. When the patients undergoing artificial respiration during hospitalization leave their sickbed, or when the patients undergo artificial respiration at home, it is necessary to change the power supply. Ventilation arrests with respirators are not rare. It is always important that the precise and prompt processing is taken with ventilation arrests.
