Cardiovascular Assessment Flashcards
(14 cards)
Why is a cardiovascular assessment important?
A cardiovascular assessment is crucial for identifying life-threatening cardiac conditions in a prehospital setting. It allows for early intervention and reduces morbidity and mortality.
What are the roles of the capillaries and veins in the heart?
The capillaries carry blood away from the heart, and the veins carry blood to the heart.
What is the Systematic system?
The systemic system is the main pathway for blood flow throughout the body, delivering nutrients and oxygen to the tissues and removing waste.
What is the Pulmonary Circulatory System?
The Pulmonary Circulatory system moves deoxygenated blood from the heart to the lungs, where it picks up oxygen and releases carbon dioxide before returning oxygenated blood to the heart.
What are the three layers of the heart?
Endocardium
Myocardium
Epicardium
What is the Endocardium?
The Endocardium is the thin, innermost layer that lines the heart chambers and valves, as well as the large blood vessels. and is composed of endothelial cells and a thin layer of connective tissue.
What is the Myocardium?
The Myocardium is the thick middle layer made up of cardiac muscle tissue, which is responsible for the heart’s contraction
What is the Epicardium
The Epicardium is the outer layer of the heart’s wall, also known as visceral pericardium, the visceral layer of the serous pericardium, which adheres to the myocardium of the heart. It is composed of mesothelial cells, fat and connective tissue and helps protect the heart and anchors it to the surrounding tissue.
What is diastole and systole?
Diastole is when the heart muscles relax and the heart fills with blood (Ventricular filling). Systole is when the heart contracts, pushing blood into the arteries (ventricular ejection)
What is Stroke Volume?
Stroke volume is the volume of blood pumped out of the left ventricle during each systolic cardiac contraction.
What is Cardiac Output
Cardiac output is the blood volume the heart pumps through the systemic circulation over a period measured in litres per minute.
What is the role of the Coronary artery?
The Coronary artery supplies the heart tissue with oxygen-rich blood.
What is the P-wave?
The P wave is the depolarisation of the atria. That triggers the atria to contract and pump blood into the ventricles.
What is the QRS complex?
The QRS complex is the depolarisation of the ventricles.
