output

 [owt´poot]
the yield or total of anything produced by any functional system of the body. When measuring output for a patient record, the volume of urine, drainage from tubes, vomitus, and any other measurable liquid should be recorded.
cardiac output the effective volume of blood expelled by either ventricle of the heart per unit of time (generally per minute); it usually refers to left ventricle output. It is equal to the stroke volume multiplied by the heart rate. Normal values are 4 to 8 liters per minute.
decreased cardiac output a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as a state in which inadequate blood is pumped by the heart to meet the metabolic demands of the body. The most obvious causative factors are pathologic changes in the heart's muscle or electrical conduction system, congenital heart defects, electrolyte imbalances (as of calcium or potassium), blood dyscrasias, and chronic pulmonary disease. Factors that could lead to changes in a patient's functional capacities because of decreased cardiac output might include physical exercise of a type or intensity that the patient cannot tolerate because of diminished oxygen supply, ingestion of large meals that place an added workload on the heart, obesity, retention of fluid (edema), hypovolemia or hypervolemia, emotional stress, and smoking.
Patient Care. Nursing interventions are planned only after a thorough nursing assessment has been conducted to collect the relevant subjective and objective data. For example, it may be that the patient will need instruction and guidance in limiting sodium intake, reducing caloric intake to lose excess fat and maintain normal body weight, decreasing fat consumption to reduce blood lipid levels, or otherwise striving for dietary management of the problem.
energy output the energy a body is able to manifest in work or activity.
stroke output stroke volume.
urinary output the amount of urine secreted by the kidneys. See also fluid balance.

car·di·ac out·put

the amount of blood ejected by the heart in a unit of time (that is, the minute volume), usually expressed in liters per minute.
Synonym(s): minute output

cardiac output

n.
The volume of blood pumped from the right or left ventricle in one minute.

cardiac output

Cardiology A measure of blood flow through the heart to the systemic circulation, expressed as volume of blood/unit time or L/min, calculated as left ventricular forward stroke X heart rate; CO is calculated by Fick method–O2 consumption divided by the AV O2 difference,
or by thermodilution, with Swan-Ganz catheterization. See Bradycardia, Tachycardia.

car·di·ac out·put

(CO) (kahr'dē-ak owt'put)
The product of heart rate and stroke volume, measured in liters per minute; the amount of blood that is pumped by the heart in 1 minute.

cardiac output

The volume of blood pumped by the heart in one minute. It is equal to the stroke volume—the output per beat—multiplied by the number of beats per minute.

cardiac output

the total volume of blood pumped out by the heart per unit time.

car·di·ac out·put

(kahr'dē-ak owt'put)
Amount of blood ejected by the heart in a unit of time in liters per minute (L/min).

showed that as the age advances, the basal metabolism decreases which lead to decrease in cardiac output as well.
[10] Recommendations for best practice include the use of alpha1-agonists for the treatment and prevention of hypotension (using boluses or infusions); left lateral uterine displacement and crystalloid co-loading or colloid preloading in addition to vasopressors for maintenance of the systolic blood pressure at [less than or equal to] 90% of baseline, and targeting maternal heart rate as a surrogate marker for cardiac output, i.e.
The major findings of this study were that the youth soccer players demonstrated a higher stroke volume, cardiac output, and peak cutaneous blood flow following HIIE in hypoxia than in normoxia.

Aortic outflow and coronary flow were timely collected and measured in graduated cylinders per five mins, cardiac output was calculated as the sum of aortic outflow and coronary out flow (CO = AoF+CE).
c - Atrial fibrillation may cause a significant decrease in cardiac output. Blood pressure is one assessment that would help the nurse determine if the patient's cardiac output is adequate.
This technique was used in our study population to measure AVF flow, recirculation and cardiac output during the first hour of haemodialysis, and measurements were collected in a patient database.
Despite different patterns of change in power output during supramaximal exercise such as the WAnT, the circulatory system rapidly adjusts to the unique demands to optimize cardiac output to the exercising legs, allowing attainment of maximal CO values as demonstrated in the current study.

Participants whose hearts pumped a lower amount of blood through the body for their body size had two to three times greater risk of developing significant memory loss over an 11-year period than those with normal, vigorous cardiac output. The results, published online Feb.
