[The Infucommand. A PCA (patient-controlled analgesia) device using pulsoximetric bolus control]

A physician who treats his patients with patient-controlled analgesia (PCA) must be aware of the possibility of unnoticed respiratory depression. A new device has been developed (Infucommand), which uses a pulsoximeter to monitor respiration and stops the infusion pump if the level of O2 saturation falls below a preset value. Thus, the danger of opioid overdosage can be reduced.
