## 1 What is the relationship between cardiac output and blood pressure?

Resistance: For fixed cardiac output, BP will vary with peripheral vascular resistance, and vice versa. The components are more complicated however. ...Read more

## Blood Pressure (Definition)

Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more

## 2 What is the connection between cardiac output and your ?Blood pressure?

V=IR: BP is a product between flow x resistance. According to ohm's law, v = i or flow x resistance or: mean arterial pressure= cardiac output x peripheral vascular resistance. ...Read more

## 3 What is the relationship between hypertension and cardiac output?

Mathematical: The relationship can be expressed as a variant of darcy' law; flow (q) = pressure/resistance. In the human circulatory system: q = (map – rap)/tpr (map = mean aortic (or arterial) blood pressure in mmhg, RAP = mean right atrial pressure in mmhg and tpr = total peripheral resistance in dynes-sec-cm-5.) however, as map>>rap, , this can be simplified to: q~map/tpr. Map is obviously affected by htn. ...Read more

## 4 What is the relationship between hr, stroke volume and cardiac output?

SEE BELOW: Cardiac output (co) = hr x stroke volume normal being 4-8 l/min. ...Read more

## 5 What is the relationship of hypertension and risk for decrease cardiac output?

Heart failure: Long-standing hypertension (or high blood pressure) leads to left ventricular hypertrophy, and if untreated, can eventually lead to congestive heart failure and decreased cardiac output. Hypertension is also a risk factor for stroke and coronary artery disease (another potential etiology for decreased cardiac output). ...Read more

## 6 How is cardiac output regulates central venous pressure?

Starling mechanism: You mean how does venous pressure regulate cardiac output.similar to the Starling mechanism-by increasing pre load. Up to a certain point cardiac output is directionally proportional to venous pressure assuming that everything else is the same such as the after load or cardiac contractility ...Read more

## 7 How does ?Cardiac output related to the blood?Circulation?

Easy: Every heart beat produces blood flow into the aorta...The flow and pumped out amount of heart beat is the output. If the heart is working well, you have normal output. ...Read more

## 9 What is the connection between high blood pressure and the heart?

Heart and others: Uncontrolled hypertension is very damaging to all organ systems -- the brain, the heart, the kidney and others. ...Read more

## 10 Formula for cardiac output via fick test using blood gases and hgb work in critical care?

Fick Cardiac Output: Cardiac ouput = vo2/13.4 x hb x(sao2 - svo2) vo2 = o2 consumption (~ 250 cc/min in healthy individual) hb = hemoglobin sao2 = arterial oxygen saturation svo2= venous oxygen saturation. ...Read more
