Significance of Cardiac Output
Cardiac output, as defined in the text, is the volume of blood the heart pumps per minute. It is a crucial measure of heart function and overall cardiovascular health. The text highlights its role in blood pressure regulation, and how it can be influenced by various factors, including emotional and physical stress, certain medications, and physiological conditions like pregnancy. Changes in cardiac output can indicate underlying health issues, such as heart failure or hyperthyroidism, and can be impacted by treatments like beta-blockers.

Hindu concept of 'Cardiac Output'
In Hinduism, Cardiac Output relates to blood volume pumped by the heart, influencing blood pressure. It's linked to Vyana-Vata, a hemodynamic force, and influenced by factors like heart rate and plasma volume. Sympathetic nervous system activity and thyroid hormones also play a role.
From: Journal of Ayurveda and Integrated Medical Sciences
(1) This is the amount of blood pumped by the heart per minute, and it is a key factor in blood pressure regulation, with certain drugs affecting it.[1] (2) This is the amount of blood the heart pumps per minute, which is increased by the sympathetic nervous system, preparing the body for action and supplying muscles with oxygenated blood.[2] (3) In younger patients with mild or labile hypertension, cardiac output may be increased and peripheral resistance may be normal.[3] (4) Cardiac output increases due to the overactivity of the sympathetic nervous system through its contractions, and it is a factor in the development of Essential Hypertension.[4] (5) This refers to the amount of blood the heart pumps per minute, and it can be affected by changes in blood volume, which can then lead to changes in blood pressure.[5]
From: International Research Journal of Ayurveda and Yoga
(1) This is the amount of blood the heart pumps per minute, which is one of the two hemodynamic forces that regulate blood pressure.[6]
The concept of Cardiac Output in scientific sources
Cardiac Output, the amount of blood the heart pumps per minute, is a crucial physiological parameter. It's influenced by factors like age, exercise, pregnancy, and various medical conditions. It's a key indicator of heart health, affected by treatments, stress, and drug effects, impacting overall circulatory function.

(1) Theophylline increases this, which is one of the benefits it provides.[7] (2) This refers to the amount of blood the heart pumps per minute, and its behavior has been studied in relation to bone cement and procedures such as cemented arthroplasty, to understand the body's response.[8] (3) Cardiac output is the amount of blood the heart pumps, and in a Fontan circulation, it depends on the passive flow of blood through the lungs and is often limited.[9] (4) This refers to the volume of blood the heart pumps per minute, and is one of the factors that determine blood pressure, and is discussed in the text.[10] (5) Cardiac output increases during exercise due to an increase in both heart rate and stroke volume, and is proportional to the intensity of the exercise, which is a fundamental exercise-induced response in the human body.[11]
From: International Journal of Pharmacology
(1) It is the amount of blood the heart pumps and it is decreased in heart failure.[12] (2) The heart's functional ability to pump blood. A decrease can lead to heart failure.[13] (3) It can increase because postoperative shivering is very unpleasant and physiologically stressful.[14] (4) The amount of blood the heart pumps per minute, which levosimendan increases without raising myocardial oxygen requirements.[15] (5) β-blockers reduce blood pressure primarily by decreasing cardiac output.[16]

(1) This is the amount of blood the heart pumps per minute, a measure of heart function and efficiency.[17] (2) This is the amount of blood pumped by the heart per minute, and it can be affected by pneumoperitoneum and the steep trendelenburg position.[18] (3) This is a measure of the amount of blood the heart pumps per minute, and it may become fixed and eventually fall as the disease progresses.[19] (4) This refers to the amount of blood the heart pumps per minute, and it is reduced in old age.[20] (5) This is a hemodynamic derivation that transesophageal echocardiography provides valuable insight on.[21]

(1) This refers to the amount of blood pumped by the heart, and the technique of bag-squeezing could cause an undesirable depression of the cardiac output.[22] (2) This is the amount of blood the heart pumps out per minute, and it can be reduced in certain conditions.[23] (3) Cardiac function is also altered such as left ventricular dysfunction in CHF resulting in a drop in cardiac output, and the research sample's cardio-respiratory response to activity was influenced by the inactivity period and prolonged use of positive pressure ventilation.[24] (4) This is the amount of blood pumped by the heart, and it can decrease when creating a positive intra-thoracic pressure with the bag.[25] (5) Cardiac output is the amount of blood pumped by the heart per minute, and it is another of the main cardiac parameters measured in studies, and some studies showed it increases with passive movements.[26]
