Cardiac output is determined by?
Cardiac output is determined by the heart rate and stroke volume. The heart rate is the number of heartbeats per minute, while stroke volume is the amount of blood ejected from the heart with each beat. Cardiac output is calculated by multiplying heart rate by stroke volume.
What is the difference between stroke volume and cardiac output?
Cardiac output is the blood volume pushed out by the left ventricle per minute. Stroke volume is the volume of blood pushed out of the left ventricle per contraction of the heart (each heart beat). So stroke volume into heart rate / minute gives you cardiac output.
How does tachycardia affect stroke volume and cardiac output?
Lowers stroke volume
Determined by heart rate x stroke volume?
cardiac output
What type of cost is fixed per unit of output and changes with volume of output?
varible?
How do you you compute urine output?
Volume and Time
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.
What does cardiac output do if the heart rate decreases?
Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.
What might an abnormal increase venous pressure indicate?
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
Which statement is correct about cardiac output?
cardiac output is heart rate multiplied by stroke volume,
How much filtration for 150Gal aquarium?
A good rule of thumb is to check the output of any filter you may consider. For most fresh water conditions I would want the filter to turn over the volume of the tank at least hourly. For marines I would want double.
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.
