Emergency Nursing Procedures: RECOVER CPR, Acute Blood Loss Control, and Fracture Stabilization

The RECOVER CPR Algorithm

The Reassessment Campaign on Veterinary Resuscitation (RECOVER) guidelines, published in 2012 and adopted worldwide, give veterinary medicine an evidence-based CPR standard. Every technician should be able to run the algorithm from memory. The VTNE tests the order, the numbers, and the rationale.

C-A-B, Not A-B-C

RECOVER uses the C-A-B sequence — Compressions, Airway, Breathing. Compressions begin first because the blood already oxygenated in the lungs at the moment of arrest must keep moving; spending time establishing an airway first sacrifices precious coronary and cerebral perfusion.

The full algorithm steps:

1. Recognize arrest — unresponsive, no spontaneous respiration, no palpable pulse (femoral or lingual artery).
2. Begin chest compressions immediately — 100–120 compressions per minute, compressing 1/3 of the chest width at full recoil. Position the dog in lateral recumbency; compress over the widest part of the chest (thoracic pump theory for round-chested dogs, cardiac pump theory for keel-chested dogs).
3. Intubate and ventilate — place an endotracheal tube ASAP and ventilate at 10 breaths/min with a manual resuscitation bag or anesthesia machine (room air or 100% O2). The compression-to-ventilation ratio is 4:1 — 4 compressions, then 1 breath, without pausing compressions longer than needed.
4. Cycle compressors every 2 minutes — fatigue drops compression quality within ~2 minutes; swap the person doing compressions on a scheduled rotation.
5. IV access and drugs — place an IV catheter (or use an existing one; IO is an option). Epinephrine 0.01 mg/kg IV (1 ml/10 kg of 1:1000) every 3–5 minutes. Vasopressin is an alternative.
6. Reversal agents when arrest is drug-induced — naloxone (opioids), atipamezole (medetomidine/dexmedetomidine), flumazenil (benzodiazepines), flumazenil and naloxone should be on hand whenever these agents are in use.
7. Defibrillate if VF/pulseless VT — 2–4 J/kg external biphasic; 4–6 J/kg monophasic. Stack shocks if needed.
8. Reassess — check for pulse and ECG rhythm every 2 minutes (during the compressor swap).

Capnography During CPR

End-tidal CO2 (EtCO2) is the single most useful monitoring parameter during CPR:

• Target EtCO2 >15 mmHg and rising — values <10 mmHg suggest poor compressions or inadequate cardiac output.
• A rising EtCO2 is the earliest sign of return of spontaneous circulation (ROSC) — it can appear before a palpable pulse.
• Falling EtCO2 during CPR means compressor fatigue or tube dislodgement — investigate immediately.

Acute Blood Loss Control

Hemorrhage is the most common preventable cause of death in trauma. The technician's response follows a clear ladder:

1. Direct pressure is the first-line maneuver for any external bleed. Apply firm pressure with gauze or a clean cloth. Most extremity and superficial wounds stop with sustained pressure for 5–10 minutes.
2. Tourniquet is reserved for limb arterial bleeds that direct pressure cannot control. Place proximal to the wound, mark the time of application, and do not leave in place >2 hours. The patient goes to surgery for definitive repair; the tourniquet is a bridge, not a treatment.
3. Hemostatic dressings (e.g., chitosan-based gauze, kaolin-impregnated gauze) are used for wounds that cannot be compressed directly (e.g., deep punctures, junctional bleeds at the axilla/groin). Pack the wound, then apply pressure.
4. Internal hemorrhage (hemoabdomen, hemothorax) is not controlled at the cage — it is identified (PCV/TS, FAST ultrasound), and the patient goes to surgery. Crystalloid and transfusion support bridge the patient to the operating room.

Key principle: do not clamp vessels blindly — you can damage nerves and adjacent structures. Apply pressure and let the veterinarian find the bleeder in a controlled setting.

Fracture Stabilization

Fractures are common emergencies and the technician's job is stabilization, not repair. The rule that prevents the most damage:

• Splint the limb in the position found. Do not attempt to straighten an angulated fracture.
• Support the limb under the fracture site when moving the patient — a hand under the fracture prevents the weight of the distal limb from grating bone ends.
• Never attempt reduction — reduction is a surgical procedure done under anesthesia. Forcibly straightening a fracture causes pain, damages soft tissues, neurovascular structures, and can convert a closed fracture into an open one by pushing bone through skin.
• Pad the splint well — cotton padding under a rigid support (padded bandage + splint material) protects skin. The splint should immobilize the joint above and below the fracture when possible.
• Open fractures — cover the wound with sterile saline-moistened gauze and a light bandage; do not scrub or explore. Administer broad-spectrum antibiotics and analgesia per protocol. Open fractures are surgical emergencies.

Stabilization Workflow

A useful mental model for the technician's role in any emergency procedure:

1. Identify the life-threatening problem (ABCs, shock, fracture).
2. Stabilize before definitive repair (oxygen, IV access, fluids, splint).
3. Communicate findings and trends to the veterinarian in real time.
4. Document every intervention and the time it was performed.

This is the foundation on which the entire emergency response rests. The next section moves from initial stabilization to the critical care that sustains the patient through the next 24 hours.
