Shortness of Breath: Emergency Steps, Breathing Techniques, and When to Call 911

Dyspnea (shortness of breath) is a medical emergency if sudden, severe, or accompanied by red flags.

Immediate Actions

1. Call 911 if: unable to speak in phrases, cyanosis, confusion, chest pain, diaphoresis, hypotension, known severe allergy (anaphylaxis), or worsening despite home measures.
2. Position: Sit upright, lean forward slightly (tripod position), shoulders relaxed.
3. Breathing Technique: Pursed-lip breathing (inhale nose 2 sec, exhale mouth 4 sec through pursed lips) — slows rate, reduces air trapping.
4. Prescribed Rescue Meds: Inhaled SABA (albuterol) for asthma/COPD; epinephrine auto-injector for anaphylaxis.
5. Oxygen: If home O₂ prescribed, use as directed.
6. Avoid Triggers: Smoke, strong odors, extreme temperatures, allergens.
7. Anxiety/Panic: Grounding (5-4-3-2-1), slow breathing, reassurance — but do not assume panic without medical evaluation.

Chronic Dyspnea Management

• Pulmonary rehab, breathing retraining (diaphragmatic, yoga).
• Optimize underlying disease (COPD, HF, ILD, obesity).
• Weight loss, smoking cessation, vaccinations.
• Advance care planning for advanced illness.

Never ignore new or worsening dyspnea. Timely intervention saves lives.
