Frequently Asked Questions

When should I call 911 for shortness of breath?
Call 911 immediately if you have sudden severe difficulty breathing at rest, bluish lips or face (cyanosis), chest pain with shortness of breath, inability to speak in full sentences, or shortness of breath after an allergic reaction or choking episode.
How do I tell if shortness of breath is from anxiety or something serious?
Anxiety-related breathing difficulty usually comes with tingling in hands/feet, a feeling of not getting enough air despite normal oxygen levels, and improves with slow breathing exercises. Seek emergency care if you have bluish skin, chest pain, high fever, coughing blood, or symptoms that don't improve with calming techniques.
How much does ER treatment for breathing problems cost?
ER visits for shortness of breath typically cost $1,500-$5,000+ depending on tests (chest X-ray, CT scan, blood work, EKG). Urgent care costs $200-$500 for less severe cases. Costs vary by location and insurance coverage.
Can I manage shortness of breath at home?
Mild shortness of breath from exertion, known asthma with a working inhaler, or anxiety can often be managed at home. Use pursed-lip breathing, sit upright, and rest. However, seek immediate care if symptoms worsen, don't improve within 15-20 minutes, or you develop any red flag symptoms.
