Overview

A secondary assessment is done after DRSABCD and after immediate life threats have been managed. It helps identify injuries, illness clues, and changes that may not be obvious at first.

SAMPLE History

Ask simple questions if the casualty can respond. If they cannot, ask bystanders or look for medical alerts.

Head-To-Toe Check

  • Explain what you are doing and gain consent where possible.
  • Look and gently feel for bleeding, swelling, pain, deformity, heat, or tenderness.
  • Check the head, neck, chest, abdomen, pelvis, limbs, and back if safe to do so.
  • Avoid unnecessary movement if spinal injury is suspected.

Vital Signs

Normal adult values vary, but useful approximate ranges are:

Check Approximate Adult Range
Temperature Around 37°C
Respiratory rate 12-20 breaths per minute
Heart rate 60-100 beats per minute
Blood pressure Around 120/80 mmHg
Oxygen saturation 95-100%

The radial pulse at the wrist is commonly used when checking circulation. Record findings, repeat them, and watch for trends such as rising pulse, worsening breathing, or falling responsiveness.
