The Bedside Paediatric Early Warning System (BedsidePEWS™) is an electronic documentation tool that is designed to be used in conjunction with multi-parameter patient monitoring. It is indicated for use by healthcare professionals with paediatric patients between the ages of term newborn (>37 weeks gestational age) and 18 years, who are hospitalized with any medical or surgical condition.
BedsidePEWS™ allows input by the healthcare professional of commonly recorded vital sign data and provides clinician with a patient status index (the “BedsidePEWS™ score”) based on a weighted average of seven vital signs when entered by the clinician, namely Heart Rate, Respiratory Rate, Blood Pressure, Oxygen Saturation, Oxygen Therapy, Respiratory Effort, and Capillary Refill. The “BedsidePEWS™ score” is a single measure of a patient’s condition and indicates the variation in the patient’s vital signs with respect to normality. BedsidePEWS™ is an adjunct to and is not intended to replace vital signs monitoring.
BedsidePEWS™ is intended for use in wards and emergency rooms in hospitals that provide care for children between the ages of term newborn (>37 weeks gestational age) and 18 years. It is not intended for use in the Neonatal Intensive Care Unit.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
