🔍 What Is Cardiac Arrest in Cats?

Cardiac arrest occurs when a cat's heart stops beating effectively—often following respiratory failure for more than six minutes—or during severe illness or anesthesia, making it an immediate life‑threatening emergency :contentReference[oaicite:3]{index=3}.

⚠️ Warning Signs & Types

Watch for these red‑flag indicators:

• Sudden collapse or unconsciousness
• Bluish gums (cyanosis), dilated pupils :contentReference[oaicite:4]{index=4}
• No response to stimulation
• Heavy gasping, labored breathing, hypothermia
• Poor pulse, no heartbeat on chest auscultation :contentReference[oaicite:5]{index=5}

🧬 Common Triggers & Underlying Causes

Cardiac arrest can stem from:

• Severe hypoxia—oxygen deprivation from respiratory failure :contentReference[oaicite:6]{index=6}
• Severe heart disease (e.g. cardiomyopathy, heart trauma, heart tumors)
• Septic shock, electrolyte imbalances, anemia
• Brain injury, severe fluid loss or trauma
• Anesthetic complications :contentReference[oaicite:7]{index=7}

🚨 First Aid & Emergency Response

If your cat collapses or stops breathing:

1. 🚨 Call your veterinarian or emergency clinic immediately.
2. 🔹 Clear airway—ensure tongue isn’t blocking breathing.
3. 💓 Begin chest compressions—at 100–120/min centrally in chest, compress ~⅓–½ depth, allow full recoil.
4. 🌬️ Provide rescue breathing—cover nose, breathe into mouth 10×/min.
5. Alternate compressions and breaths in cycles (30:2) until help arrives.
6. Monitor pulse and breathing—stop CPR if signs of recovery occur.

🏥 Hospital Care & Diagnosis

At the clinic, your cat will undergo:

• Airway support and oxygen therapy :contentReference[oaicite:8]{index=8}
• Cardiopulmonary Resuscitation (CPR)—including intubation, chest compressions, medications
• Monitoring: ECG, blood pressure, pulse oximetry, body temperature
• Diagnostics to find cause: chest X‑rays, echocardiogram, ECG, bloodwork, blood gases, electrolytes :contentReference[oaicite:9]{index=9}

💉 Treatment & Stabilization

• Medications for heart rhythm support and circulation
• IV fluids to correct dehydration, shock, or metabolic issues
• Treat underlying condition—e.g. infections, electrolyte imbalance, trauma
• Possible open‑chest resuscitation or intracardiac drug administration in critical cases—rarely required :contentReference[oaicite:10]{index=10}

📅 Prognosis & Long‑Term Care

Unfortunately, cardiac arrest has a low survival rate—less than 10% recover long-term even with prompt care :contentReference[oaicite:11]{index=11}.

For those that survive:

• Hospitalization for 24–72 hours for monitoring
• Treatment of underlying disease—e.g., heart failure or infection
• Rehabilitation, oxygen therapy, nutritional support
• Follow-ups: ECGs, bloodwork, echocardiograms to assess recovery

Outcomes vary based on cause—those with reversible issues may do well; chronic heart disease carries a guarded to poor long-term prognosis :contentReference[oaicite:12]{index=12}.

🛡️ Prevention & Monitoring

• 🏥 Regular wellness checks—early detection of heart or respiratory disease
• 🫁 Home respiratory monitoring—watch resting rate; >30 breaths per minute may be concerning :contentReference[oaicite:13]{index=13}
• 💓 Screen at‑risk cats (e.g., HCM) via echocardiogram
• ⚖️ Manage chronic diseases—heart conditions, anemia, kidney disease
• 💉 Careful anesthetic planning with your vet

🐾 Advice for Cat Parents

• 📅 Learn CPR basics from your vet or certified courses
• 🧭 Keep emergency contact numbers visible
• 📋 Track breathing rate, appetite, energy, and symptoms
• 📲 Use the Ask A Vet app for urgent advice
• 🏠 Provide supportive home care—quiet rest, nutrition, oxygen if prescribed
• 🛌 Use calming tools from Woopf & Purrz to reduce stress during recovery
