First Aid and CPR Courses: Recognizing and Responding to Angioedema

Sudden swelling of the face, lips, or throat can be alarming and potentially life-threatening. In professional first aid and CPR courses, participants learn how to recognize conditions like angioedema and respond quickly to protect the airway and activate emergency care.

Angioedema is rapid swelling that occurs in the deeper layers of the skin and mucous membranes. Unlike hives, which affect the surface of the skin, angioedema affects deeper tissues and may occur with or without hives.

What Is Angioedema?

Angioedema involves fluid buildup beneath the skin and can affect areas such as:

• Lips and face
• Eyes and eyelids
• Hands and feet
• Genitals
• Tongue and throat

While many cases are mild, swelling that affects the airway should always be treated as a medical emergency.

Types of Angioedema (Awareness Only)

First aid courses teach recognition, not diagnosis. However, awareness of common categories helps responders understand risk:

• Allergic angioedema: Often triggered by foods, insect stings, or medications
• Drug-related angioedema: Linked to certain medications
• Hereditary angioedema: A rare genetic condition
• Idiopathic angioedema: No clear cause identified

Regardless of cause, first aid response priorities remain the same.

Signs and Symptoms to Recognize

As taught in first aid and CPR courses, warning signs of angioedema may include:

• Rapid swelling of the lips, eyes, face, or tongue
• Tightness or discomfort in the throat
• Difficulty breathing or swallowing
• Hoarse voice or coughing
• Painful or firm swelling
• Vision changes if swelling affects the eyes

Any breathing difficulty requires immediate emergency response.

First Aid Response for Angioedema

Angioedema is not always life-threatening, but first aid certification emphasizes early action and airway protection.

Appropriate first aid actions may include:

• Calling emergency services immediately if breathing is affected
• Helping the person sit upright and stay calm
• Monitoring airway, breathing, and responsiveness
• Assisting with self-administered epinephrine if prescribed and trained
• Preparing to begin CPR if the person becomes unresponsive and is not breathing normally

First aid responders do not diagnose or treat angioedema and should not administer medications unless specifically trained and authorized.

When Angioedema Becomes an Emergency

Emergency care is required if:

• Swelling involves the tongue or throat
• Breathing or swallowing becomes difficult
• Symptoms progress rapidly
• The person shows signs of anaphylaxis
