Final answer:
Cardiac Arrest is the sudden failure of the heart to pump blood, often leading to loss of consciousness and absence of breathing, and it is a medical emergency. It is typically caused by an underlying heart condition such as coronary artery disease, which can result in angina or heart attack. It is crucial to distinguish cardiac arrest from other medical issues such as chronic lung diseases or mild chest pain.
Step-by-step explanation:
Cardiopulmonary Arrest, also known as Cardiac Arrest, refers to the failure of the heart to pump blood effectively, which is a medical emergency requiring immediate intervention. This condition should not be confused with conditions like chronic lung disease, mild chest pain, or sudden breathing difficulties, which correspond to other medical issues. Cardiac arrest occurs when the heart's function is abruptly stopped or is so impaired that it fails to pump blood to vital organs.
Coronary artery disease can lead to conditions such as angina and myocardial infarction (heart attack), which in turn may cause cardiac arrest. Angina is a symptom indicating cardiac cells are receiving inadequate oxygen, often experienced as chest pain, whereas a heart attack happens when blood flow to part of the heart muscle is blocked, leading to the death of cardiac tissue. It's crucial to understand that while conditions like chronic obstructive pulmonary disease (COPD) involve respiratory symptoms like shortness of breath and phlegm production, they are distinct from cardiac conditions.
