PREPARED BY:
Joel Taller Basabe CN/ICU
EWS PROJECT MANAGER
Learning Objectives:
• Be able to recognise that children deteriorate more rapidly than adults.
• Be able to calculate a Paediatric Early Warning Score
• To be aware of responsibilities when a trigger score is met
• Be able to complete the age appropriate observation chart.
Introduction
The Paediatric Early Warning Score (PEWS) like the adult MEWS is a bedside score that is calculated by nursing staff to indicate early signs of a patient’s deterioration.
The PEWS looks at all the observations together, not just a single observation in …show more content…
A. Inadequate Cardiac Output
Cardiac output is integral to the amount of oxygen being delivered to the tissues. If the cardiac output falls, it is likely that oxygen delivery will fall.
If there is inadequate oxygen delivery to the tissues, inadequate amounts of ATP can be generated which is vital for cellular function.
This is turn leads to organ failure, lactate formation and shock. B. Inadequate Pressure Gradient
Clearly without a pressure gradient across the vasculature (from high pressure to low pressure) there can be no flow of blood and its constituents including oxygen which is vital for the generation of ATP and hence life.
Some organs are able to maintain blood flow through organs despite changes in blood pressure (autoregulation) e.g.: brain and kidney. However, there reaches a point when this can no longer occur if the blood pressure is too low and this in turn reduces blood flow and hence the amount of oxygen reaching the
