## Key points

- Resting adult (MedlinePlus): pulse 60 to 100 beats per minute; breathing 12 to 18 per minute (OpenStax gives 12 to 20); blood pressure 90/60 to 120/80 mmHg; temperature 36.5 to 37.3 °C.
- Read every value against the patient's age and previous readings; the trend matters more than one reading.
- For an abnormal reading, repeat it (another thermometer, another route, the other arm) and assess the patient before concluding.
- Record the value, unit, route or site, time and, for an abnormal value, what was done and who was told.
- Blood pressure is usually taken last, because the cuff is the most uncomfortable part.

## What it is

Vital signs are the basic measurements of body function: temperature, heart rate (pulse), respiratory rate and blood pressure. Oxygen saturation and pain are often added. Their value lies in the trend: a single reading says little, a series shows whether the patient is improving or worsening. They are taken on admission, with every change in condition and as often as the unit's protocol requires.

## Key facts

- Temperature: 36.5 to 37.3 °C (average 37 °C); fever from 38 °C.
- Heart rate: 60 to 100 beats per minute.
- Respiratory rate: 12 to 20 breaths per minute.
- Blood pressure: about 90/60 to 120/80 mmHg.
- Oxygen saturation: 95 to 100% on room air.
- Pain: recorded with a validated scale (0 to 10 in adults).

## Step by step

- Review previous readings, history and orders on frequency and call-out parameters.
- Gather equipment: thermometer, watch with a second hand, stethoscope, oximeter and a sphygmomanometer with the right cuff.
- Identify the patient, explain, clean your hands and let the patient rest for a few minutes.
- Take the temperature and note the route (oral, axillary, tympanic, rectal).
- Count the pulse and then, fingers still on the wrist and without saying so, count breaths by watching the chest.
- Measure oxygen saturation and ask about pain with a scale.
- Take blood pressure last and record everything with the time, site and method.

## Test yourself

Think of the answer, then tap the question to see it.

## Why are breaths counted without telling the patient?

Because a patient who knows they are being watched unintentionally changes the rate and depth of breathing.

## What is done with an abnormal blood pressure reading before reporting it?

Repeat it with correct technique, ideally also in the other arm, and assess the patient for symptoms.

## What is the normal resting heart rate in an adult?

Between 60 and 100 beats per minute; trained athletes may have 40 to 60 without disease.

## What details should accompany a recorded temperature?

The value with its unit, the route used (oral, axillary, tympanic or rectal) and the time of measurement.
