1Field Safety Notice on Volumetric Infusion Pumps: Cohort-Specific Withdrawal or Continued Use?
During a biomedical safety round in a 1,200-bed acute hospital in Kowloon, your team identifies 86 volumetric infusion pumps (model VP-400, firmware v3.2, installed 2023) within an affected serial range. The supplier has issued a Field Safety Notice: below 5 mL/h the pump may over-deliver by up to 12%, traced to a stepper-motor calibration routine introduced in v3.2.

In a district general hospital day-surgery unit, a newly installed electrosurgical unit (ESU, 400 W monopolar, 350 kHz) in Theatre 3 coincides with baseline wander on ECG Lead II and spurious NIBP readings of 60/30 mmHg during a laparoscopic cholecystectomy. The anaesthetist notes the SpO2 plethysmograph looks normal and the patient is clinically stable.
