Science blog reported new guidelines for pet CPR that every fur family should be aware of.
- Perform 100-120 chest compressions per minute of one-third to one-half of the chest width, with the animal lying on its side.
- Ventilate intubated dogs and cats at a rate of 10 breaths per minute, or at a compression to ventilation ratio of 30 to 2 for mouth-to-snout ventilation.
- Perform CPR in 2-minute cycles, switching the “compressor” each cycle.
- Administer vasopressors every 3–5 minutes during CPR.
Chest compression techniques for medium, large, and giant breed dogs. (A) For most dogs, it is reasonable to do chest compressions over the widest portion of the chest to maximally employ the thoracic pump theory. Either left or right lateral recumbency are acceptable. (B) In keel-chested (ie, deep, narrow chested) dogs like greyhounds, it is reasonable to do chest compressions with the hands directly over the heart to employ the cardiac pump theory, again in either recumbency. (C) For barrel-chested dogs like English Bulldogs, sternal compressions directly over the heart with the patient in dorsal recumbency may be considered to employ the cardiac pump mechanism.
Chest compression techniques for small dogs and cats. (A) For most cats and small dogs (<10 kg) with compliant chests, the use of a 1-handed technique to accomplish circumferential chest compressions with the hand wrapped around the sternum directly over the heart may be considered. (B) An alternative chest compression method for cats and small dogs is the 2-handed technique directly over the heart to employ the cardiac pump mechanism. This method may be considered in larger cats and small dogs with lower thoracic compliance, or in situations in which the compressor is becoming fatigued while doing 1-handed compressions.
