Abstract:
More than 250 000 cardiac surgical procedures are performed annually in the United States. Postoperative cardiac arrest rates range from 0.7% to 5.2%. This article reviews current evidence for cardiac arrest resuscitation after cardiac surgery. The evaluation included resuscitation guidelines and 22 studies identified through a MEDLINE search. Evidence-based resuscitation differs from advanced cardiovascular life support guidelines. European Resuscitation Council guidelines include correcting reversible causes of arrest, applying defibrillation/pacing before external cardiopulmonary resuscitation, resternotomy within 5 minutes if electrical therapies fail, and restricting epinephrine use to avoid rebound hypertension. A 2017 Society of Thoracic Surgeons protocol derived from European Resuscitation Council guidelines is now standard of care in the United States. Evidence-based practices can improve survival and reduce resternotomy rates. This article describes the clinical implementation of the Society of Thoracic Surgeons guidelines.

Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...
Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...
