How Do Potassium Levels Affect Cardiac Output
Not directly: Cardiac output is the amount of blood flow generated by the heart over a given time frame. Potassium is a critical electrolyte for body health and cardiac function, especially its rhythm. Although high or low potassium levels can create major, potentially fatal, irregularities in the heart rhythm, those levels do not directly affect the cardiac output per se. ...Read moreSee 1 more doctor answer
Levels = volumes?: Blood levels meaning blood volumes? Cardiac output is the volume of blood being pumped by the heart per minute. It is calculated by stroke volume x heart rate. Stroke volume is the volume of blood pumped from one ventricle of the heart with each beat. ...Read moreSee 1 more doctor answer
5 liters/min: A typical cardiac output is approximately 5 l per minute. This can vary with the size of the patient with a larger patient having larger cardiac output. When the cardiac output is normalized for the size of the patient, this is called the cardiac index. A typical cardiac index would be 2.5. A number of medical conditions, such as fever or anemia, can increase the cardiac output. ...Read moreSee 1 more doctor answer
If someone goes into cardiac arrest from extremely low potassium blood level. Would the defibrillator work? Or do they need the potassium
Exercise: In order to facilitate the increase in oxygen demand of the muscles during exercise, the heart rate and volume of blood per beat will go up. Cardiac output is the product of heart rate times stroke volume. Therefore cardiac output will increase with exercise. ...Read moreSee 1 more doctor answer
Cardiac output: In strict physiologic terms, cardiac output is determined by something called stroke volume and heart rate. Heart rate is self-explanatory. Stroke volume is the amount of blood that the heart pumps out with each beat. This in turn is dependent on blood pressure, total blood volume, and how strong the heart contracts. ...Read moreSee 1 more doctor answer
Can being a prior endurance athlete (but not currently trained) permanently affect cardiac output resulting in high numbers when all else is normal?
Athletic Heart: Interesting question! former athletes have been shown to have more left ventricular hypertrophy or thickened hearts that usually lessens with age and deconditioning. A thick heart can lead to poor heart filling by increased stiffness. A condition called diastolic dysfunction. This can lead to a type of congestive heart failure if it persists. Controlling hr and BP via meds can help. ...Read more
