What else can I help you with?
What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
Is Cardiac output equal on both sides of heart?
Yes, it must be so in a healthy heart. The reason is very simple. The left and right ventricles pump in the same cycle (and, if this were not the case, there would be a backlog of fluid in one system or the other).
What organ in the body has specialized cells that work together to form cardiac muscle tissue?
Answer for anyone looking is the fact that the cardiac muscle never stops, it cannot, otherwise you would die.
Cardiac mass icd 9 code?
Without any further information about the nature of the mass, the ICD 9 code to use for a cardiac mass would be 429.89.
Why would urine output be increased after surgery?
IV fluids.
What decreases cardiac output without change in heart rate PAWP or SVR Is it preload afterload or contractility?
A change in cardiac output without any change in the heart rate, pulmonary artery wedge pressure (PAWP = equated to preload) or systemic vascular resistance (SVR = afterload) would have to be due to a change in the contractility of the heart. Cardiac output (CO) is roughly equal to stroke volume x heart rate. Stroke volume is related to preload, contractility, and afterload. As you can see, the only variables you have not controlled for is cardiac contractility.
Which of the following would have a negative impact on cardiac contractility?
Norepinephrine
What effect does stimulation of acetylcholine receptors of the heart have on cardiac output?
The effect would be an increase in cardiac output. However, there is a maximum level and then the heart would not have time to fill fully and the output would decrease.
What effect does stimulation of the acetylcholine receptors of the heart have on cardiac output?
The effect would be an increase in cardiac output. However, there is a maximum level and then the heart would not have time to fill fully and the output would decrease.
Would result in a decrease in cardiac output?
A decrease in cardiac output can result from various factors, including reduced heart rate, diminished stroke volume, or impaired myocardial contractility. Conditions such as heart failure, severe dehydration, or significant blood loss can lead to these changes. Additionally, factors like increased systemic vascular resistance can also contribute to a decrease in cardiac output. Overall, any condition that negatively affects the heart's ability to pump effectively or reduces blood volume can lead to lowered cardiac output.
Would cardiac output increase or decrease during dehydration?
Cardiac output typically decreases during dehydration. When fluid levels are low, there is less circulating blood volume, leading to a decrease in the amount of blood pumped out by the heart per minute. This reduction in cardiac output helps conserve remaining fluids in the body.
Does cardiac output affect urine output?
Certainly. Decrease cardiac output would mean a decreased in blood flow to the kidneys, which would lead to reduced filtration, therefore urine output.
What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
How would acute coronary syndrome effect cardiac output?
I will decrease cardia output
What effect would compressing the inferior vena cava just below the diaphragm have on cardiac function?
Compressing the inferior vena cava below the diaphragm can decrease venous return to the heart, leading to reduced preload and consequently a decrease in cardiac output. This can result in decreased blood flow to the rest of the body and potentially lead to symptoms like lightheadedness or hypotension.
How would a decrease in blood volume affect both stroke volume and cardiac output?
It's decreased ... unless the rate falls, which is the normal cardiac response.
What will the venous return be if the cardiac output is 7.5 liters?
Venous return must always match cardiac output. So a CO of 7.5 l/m mill mean a VR od 7.5 l/m
