Assessing an Unconscious Patient: Essential Techniques

Knowing how to quickly assess an unconscious patient is crucial for medical responders. This skill can make the difference between life and death. What steps should be followed to ensure an effective and safe assessment? This article details the fundamental techniques and best practices for first responders, in line with training programmes such as BLS-AED-SRC, IAS 1 and IAS 2.

First Steps and Scene Assessment

When faced with an unconscious patient, your first task is to assess the safety of the scene. This step is essential to ensure your safety and that of others. Make sure there are no imminent hazards, such as fires, gas leaks or traffic risks. Once the area is safe, approach the patient to assess their condition.

Techniques for Checking Vital Signs

The initial assessment of an unconscious patient begins by checking their vital signs: breathing and pulse. Observe the patient’s chest to see whether it rises and falls, and listen for any breathing sounds. Check the pulse at the carotid artery, located on the side of the neck, to determine whether the heart is beating and how fast. If the patient is not breathing normally and has no pulse, immediately begin cardiopulmonary resuscitation (CPR) and call for help.

Using the ABC Approach: Airway, Breathing, Circulation

Follow the ABC approach for a systematic assessment:

Airway: Make sure the patient’s airway is not obstructed. Gently lift the chin and tilt the head back to open the airway.
Breathing: Check the patient’s breathing. If the patient is not breathing or their breathing is abnormal, prepare to provide rescue breaths.
Circulation: After establishing that the airway is clear and breathing is effective, assess circulation. Check the skin colour, temperature and whether there is any bleeding.

Rapid Neurological Assessment

Use the AVPU scale to quickly assess the patient’s level of consciousness:

A (Alert): Is the patient alert?
V (Voice): Does the patient respond to your voice?
P (Pain): Does the patient respond to pain?
U (Unresponsive): Is the patient completely unresponsive?
This rapid assessment helps determine the urgency of the situation and whether immediate medical intervention is required.

Preparing for Medical Transport

If the patient requires hospitalisation, prepare them for transport. Stabilise the patient while continuing to monitor their vital signs. Make sure all emergency equipment is ready and accessible. Finally, inform the hospital medical staff of the patient’s condition and the interventions performed.

Summary of Actions and Follow-Up

Review the key steps and observations made during the patient’s assessment. This summary will help inform the healthcare professionals taking over and ensure effective continuity of care. The skills discussed are an integral part of training programmes such as BLS-AED-SRC, IAS 1 and IAS 2, which are essential for all medical responders.
