Rationale and key points

Temperature is a vital sign that is included in all early warning scoring tools and as part of patient observations. This article outlines the main non-invasive methods that can be used to measure a patient’s temperature.

• Temperature is important in establishing a baseline to evaluate treatment, monitoring signs of any allergic reaction or infection, and recognising significant changes in temperature, for example hypothermia and hyperthermia.

• Nurses should understand the pathophysiology of temperature regulation and be familiar with the various methods used to measure temperature. They should also be aware of the environmental factors that may result in inaccurate temperature readings.

• It is crucial to identify any signs of clinical deterioration in patients, including elevated or lowered temperature, and respond to these in a timely manner.
