A urine output greater than 30ml/hr usually indicates an adequate cardiac output true or false?

Answer 1

False

Answer 2

I am not sure what you mean by "cardiac output". As an ex-surgical nurse we used >30ml/hr as an indication of fluid balance and renal function stability. Less than that amount over a long period of time would suggest that the patient is at risk of kidney failure. You have to consider the patient holistically, checking TPR and blood pressure. Are they dehydrated or hypoperfused? I would say that urine output alone is not a reliable indication of cardiac stability but one of many important indicators

Answer 3

Normal urine output for an adult is apx. 40 cc/hr. A low urine output is called oliguria. The renal (kidneys) system is the major player in urine output. You can not judge cardiac output performance by merely looking at urine output.There are other factors that need to be considered. Cardiac output is equivalent to "stroke volume x heart rate" You need to go visit the local cardiologist for some hemodynamic testings.

Answer 4

In an indirect way. As cardiac output and BP drops, the kidneys do not get perfused as well and urine output can drop. It should return to normal as BP rises to a normal value.{ as long as it has not been low for an extended period of time} But that is not the only reason for a drop in urine output.

Answer 5

Not necessarily an indicator of cardiac output but an indicator of renal function. 30mls/hr is the minimum amount one should be excreting. Any lower and one is in big trouble.

Answer 6

Normal urine output is 40cc/hr and urine output is directly related to cardiac output so I would say the answer is true...

Answer 7

False. Urinary output is dependant on water intake, not cardiac output.
