Pertaining to the heart and lungs.

• c. arrest (CPA) — cessation of effective external respiration and beating of the heart. The common causes in animals are inadequate ventilation, caused by general anesthetic, thoracic trauma, airway obstruction, and impediments to movement of the lung, thoracic wall or diaphragm, acidemia, hypotension, electrolyte imbalance, or extreme changes in body temperature (hypothermia, hyperthermia).
• c. resuscitation (CPR) — the re-establishment of heart and lung action. The basic steps are: Airway, Breathing, Circulation. A patent airway must be established and maintained; any obstruction is relieved and an endotracheal or tracheostomy tube inserted. Adequate ventilation with oxygen is provided by intermittent positive pressure and, if required, cardiac (chest) compression or massage is commenced.
