What is the word equation for stoke volume?
The word equation for stroke volume is the amount of blood pumped by the heart in one contraction. It is calculated by subtracting the amount of blood remaining in the ventricle after contraction (end-systolic volume) from the amount of blood in the ventricle just before contraction (end-diastolic volume).
What is a graph illustrating the pressure and volume changes during one heartbeat called?
That graph is known as a pressure-volume loop. It is used in cardiology to assess cardiac function and to visualize the changes in pressure and volume within the heart during one cardiac cycle.
What causes insufficient oxygen?
Insufficient oxygen in the air can be caused by consumption of the oxygen in a space that is sealed and cannot mix with the larger environment. This happens if one or more people are breathing in a sealed space like an old-fashioned bank vault, if a fire is burning in a closed space, if organic matter is decomposing in a closed space, if metals are oxidizing (rusting) in a closed space like a tank or the hold of a ship. Insufficient oxygen in the air can also be caused by the release of other gasses, such as nitrogen, for example, in a way the displaces the rest of the atmosphere. This can happen in fully enclosed spaces, but also in pits and other spaces that are only partially enclosed. Insufficient oxygen in the air can also be encountered when you are at increased altitude above sea-level, simply because all elements of the air become thinner (less) as the altitude increases. Then, if your lungs are damaged, you may be in an atmosphere that has sufficient oxygen but be unable to get it into your body in sufficient quantity because the lungs are not working at reasonable capacity.
What is the difference between overhydration and excess blood volume?
Overhydration is characterized by excess water both within and around the body's cells, while excess blood volume occurs when the body has too much sodium and can not move water to reservoirs within the cells.
What test measures the flow of blood through the heart during activity is evaluated by injecting thallium into the bloodstream?
The test you are referring to is called a thallium stress test. This test helps evaluate the blood flow to the heart during physical activity by using a radioactive form of thallium injected into the bloodstream. It can help identify areas of reduced blood flow in the heart muscle, indicating possible blockages in the coronary arteries.
What is determined by stroke volume x heart rate x systemic vascular resistance?
This is the best mathematical way to understand blood pressure. Blood pressure = (stroke volume x heart rate) x systemic vascular resistance.
Is the bleed heart vascular or non vascular?
nonvascular
Heart is in what system?
The cardio-vascular system
Prefix referring to heart?
The prefix referring to the heart is "cardio-."
What is cardiac output affected by?
Cardiac output is affected by several factors, including heart rate and stroke volume. Heart rate is the number of beats per minute, while stroke volume is the amount of blood pumped by the heart with each beat. Additionally, factors such as blood volume, vascular resistance, and the contractility of the heart muscle can also influence cardiac output. Changes in these parameters can lead to variations in overall blood flow to the body's tissues.
Is stroke volume inversely proportional to the after load?
Yes, stroke volume is inversely proportional to afterload. An increase in afterload, such as from increased vascular resistance, can lead to a decrease in stroke volume due to the additional pressure the heart has to work against to eject blood. Conversely, decreasing afterload can help increase stroke volume.
What is the vascular?
It just means the heart and blood vessels.
What is consumptive heart failure?
Heat is pumping insufficient blood
What is the vascular system?
It just means the heart and blood vessels.
What are the components of a vascular system?
a pumping heart and blood vessels
What is cadio vascular?
Cardiovascular means pertaining to the vessles in the heart
What is systemic vascular resistence?
The resistance the heart has to pump against
