Observing the sick child: Part 2a. Respiratory assessment.

As the focus on evidence-based healthcare delivery gains momentum, nurses need to critically reflect on their traditional practice base. Assessment is the cornerstone of safe and effective practice and goes hand in hand with the process of prioritising a sick child's needs. This article begins with a practical and critical review of the validity and reliability of basic respiratory assessment focused on measurement of respiratory rate, rhythm and depth. Part 2b in February 2007 will be a practical step-by-step introduction to the theory and practice of advanced respiratory assessment using palpation. Part 2c in the following month will focus on respiratory auscultation methods.
