Chapter 21 Flashcards
Cardiac arrest
When the heart no longer pumps blood
Chain of survival
- Recognition
- Immediate high quality CPR
- Rapid defibrillation
- Basic and emergency medical services
- Advanced life support
Defibrillation
An electric shock that stops fibrillation of heart muscles to restore a normal heart rhythm
Chronic hypertension
High blood pressure
Pericardial tamponade
when fluid accumulates in the pericardium, the sac around the heart, and compresses the heart
Pulseless electrical activity
When the hearts electrical rhythm is normal but the mechanical pumping fails
Commotio cordis
Potentially life-threatening condition caused by a sudden, blunt impact to the chest, typically during sports activities. This impact can lead to a disruption of the heart’s rhythm.
Asphyxial arrest
Ceasing to breathe due to lack of oxygen.
Agonal breathing
irregular, gasping breaths that may be slow and labored. Agonal breathing is usually a sign of severe respiratory or cardiac distress and is often associated with a life-threatening situation
Apnea
temporary cessation or pause in breathing
Cardiopulmonary resuscitation
Cardiopulmonary resuscitation (CPR) is an emergency life-saving technique performed when an individual’s heart or breathing has stopped
Cerebral perfusion pressure
the pressure of blood within the brain’s blood vessels, specifically within the cerebral arteries
Coronary perfusion pressure
the pressure gradient that drives the blood flow to the coronary arteries
Compression fraction
proportion of time during cardiopulmonary resuscitation (CPR) that chest compressions are actively being performed
Sludging
the slow movement or accumulation of substances, such as blood cells or particles, within the circulatory system
