Cardiopulmonary arrest (CPA): abrupt and unexpected cessation of spontaneous effective ventilation and circulation
Cardiopulmonary resuscitation (CPR): provides artificial ventilation and assists circulation until advanced life support
is provided or spontaneous cardiopulmonary function is restored.
CPCR: cardiopulmonary cerebral resuscitation
Anesthetic arrests and patients with reversible conditions should be resuscitated aggressively.
Reasons for such a poor success rate include severity of underlying disease, delay in the recognition of CPA, and delay
in delivery of appropriate therapy.
Training (practice sessions), calculated drug chart, crash cart supplies
Recognition of potential CPA patients, physical and laboratory monitoring
A B C's: Airway Breathing Circulation
Assess the effectiveness of each.
A: Open jaws and examine airway for patency, obstruction, secretions. You'll need assistance; always use a laryngoscope.
A suction system is very helpful. Quickly pre-measure tube. Intubate; tie tube in immediately. Visual marker to prevent tube
migration. Tracheostomy may be needed for upper airway obstruction
B: Take a few seconds and see if chest wall is rising, feel and listen for airflow. If not, attach 100% oxygen. Start with
2 or 3 full breaths and reassess spontaneous breathing. If not present, continue to ventilate the patient 15 to 25 breaths
per minute. General inspiratory pressures for a dog is 20cm H20, 15 cm H20 for the cat. Breather should communicate with
code leader as to how much pressure is needed to expand the chest. Thoracocentesis may be warranted, particularly in the trauma
or chronic disease patient. Monitor airway tube for pulmonary fluid; suction PRN.
C: Feel for a pulse. If none present, begin cardiac compressions. 80 - 120 compressions per minute with animal in lateral
recumbency. Lower table or stand on step stool; Compress directly over the heart to compress the thorax 25-30% by leaning
into patient with elbows bent. Increase ventilations and apply simultaneously with compressions. Assess retinal blood flow
