Basic Life Support for Nurses
Basic Life Support for Nurses focuses on immediate recognition of cardiac arrest and high quality
emergency response. Nurses use this area of practice to identify risk early, guide safe interventions, and
support better patient outcomes through timely reassessment and documentation.
1. Why this topic matters
Basic life support is a core nursing emergency skill. Rapid recognition of unresponsiveness, activation of help,
effective chest compressions, and AED use improve survival while advanced support is mobilized.
In day to day practice, the nurse links bedside findings with the wider clinical picture. A single observation can
be reassuring, but a pattern of change often signals deterioration. For that reason, this topic should always be
approached with attention to baseline status, trend over time, comorbidity, treatment already in progress, and
the patient perspective.
Assessment priorities
Assessment domain What the nurse checks
Safety Check scene safety before touching the patient.
Responsiveness Assess whether the patient responds to voice or pain.
Breathing Look for normal breathing rather than occasional gasping.
Pulse Check for a pulse only within the recommended time if trained to do so.
AED access Identify whether a defibrillator is available and ready.

Quick practice note
The first assessment is not the end of care. Reassessment after intervention is essential because
improvement or deterioration often becomes visible only when the same parameters are checked again and
interpreted in context.

2. Assessment approach and interpretation
Safety
Check scene safety before touching the patient.
When documenting safety, include the observed value or finding, associated symptoms, and any factor that
might change interpretation such as treatment, activity, anxiety, pain, recent medication, or baseline variation.
Responsiveness
Assess whether the patient responds to voice or pain.
When documenting responsiveness, include the observed value or finding, associated symptoms, and any
factor that might change interpretation such as treatment, activity, anxiety, pain, recent medication, or baseline
variation.
Breathing
Look for normal breathing rather than occasional gasping.
When documenting breathing, include the observed value or finding, associated symptoms, and any factor that
might change interpretation such as treatment, activity, anxiety, pain, recent medication, or baseline variation.
Pulse
Check for a pulse only within the recommended time if trained to do so.
When documenting pulse, include the observed value or finding, associated symptoms, and any factor that
might change interpretation such as treatment, activity, anxiety, pain, recent medication, or baseline variation.
AED access
Identify whether a defibrillator is available and ready.
When documenting aed access, include the observed value or finding, associated symptoms, and any factor
that might change interpretation such as treatment, activity, anxiety, pain, recent medication, or baseline
variation.

Interpretation tip
If assessment findings do not match the overall patient picture, the safest response is usually to repeat the
measurement, inspect contributing factors, and look for linked symptoms before deciding that the value is
normal or abnormal.
