analyzing 3 fault cases of PB480 ventilator in our hospital. The fault cases described in this paper included suddenly black screen
during use, alerting of abnormal function after start and no display of touch screen after start. These faults were solved by software
log analysis, EST self-inspection, replacement of parts, on the basis of understanding relevant circuit. When PB480 encounter faults,
the first thought should be using EST self-inspection function offered by ventilator to locate the fault and reset relative parts, error
code and relative event records should be inquired in combination with log function of PB480. Maintenance work should be carried
out according to failure phenomenon, start from the cause of greatest possibility and easiest mastery, so as to save human and material
