perfusion

 [per-fu´zhun]
1. the act of pouring through or over; especially the passage of a fluid through the vessels of a specific organ.

tissue perfusion the circulation of blood through the vascular bed of tissue.
ineffective tissue perfusion (specify type) (renal, cerebral, cardiopulmonary, gastrointestinal, peripheral) a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as a state in which an individual has a decrease in oxygen resulting in failure to nourish the tissues at the capillary level.

perfusion

Bathing an organ or tissue with a fluid. See Arterial perfusion, Hyperthermic perfusion, Isolated hepatic perfusion, Limb perfusion, Myocardial perfusion Oncology A technique used for a melanoma of an arm or leg; circulation to and from the limb is stopped with a tourniquet; chemotherapy is put directly into the circulation to ↑ regional drug dose Transplantation The intravascular irrigation of an isolated organ with blood, plasma or physiologic substance, to either studying its metabolism or physiology under 'normal' conditions or for maintaining the organ as 'fresh' as possible, while transporting donated organs to recipients.

With the impaired cardiac pressure-volume relationship, deteriorated microcirculation due to the sepsis-like syndrome makes the routine evaluation of postoperative tissue perfusion difficult to interpret.
The risk factor of high frequency, i.e., above the 75th percentile, that is, "risk for ineffective gastrointestinal perfusion", the risk factor DM (100.0%) was the most observed in people of this group research; regarding the ND "Risk for ineffective renal perfusion", "Risk for decreased cardiac tissue perfusion", "Risk for ineffective peripheral tissue perfusion", "Risk for impaired cardiovascular function", risk factors for hypertension (100.0%) and DM (100.0%).
We want to have a new outlook of "Role of dose-dependent progesterone-induced general vasodilatation with better tissue perfusion as the reason for decreased erythropoietin inturn decreased erythrocyte count" rather than the present accepted explanation of "Increased tissue fluid retention as the reason for decreased hematocrit value and reason for decreased erythrocyte count during pregnancy."
The recent study was undertaken to examine the cardio-protective effect of NNBP on myocardial tissue perfusion, cardiac myocyte apoptosis, myocardial stunning, and heart contractile function in hypertrophied hearts.
Pneumoperitoneum during laparoscopy produces significant haemodynamic changes such as increase in mean arterial pressure, increase in pulse rate, decrease in cardiac output and increase in systemic vascular resistance which in turn compromises tissue perfusion dreadful in elderly and haemodynamically unstable patients (Dhoste k et al 1996).
The acquisition expands Sotera's patented technology portfolio to include RMI's FDA-cleared Mobile CareGuidetechnology for the measurement of two parameters that provide physiological information beyond the scope of vital signs: muscle oxygen saturation, to determine the adequacy of tissue perfusion, and muscle pH, an indication of acidosis.
Tissue perfusion is proportional to the difference between the interstitial fluid pressure and the capillary perfusion pressure.
More specifically, vasopressors are used to raise blood pressure to facilitate adequate tissue perfusion (thus allowing for sufficient supply of oxygen and other nutrients to reach body cells and to remove metabolic wastes) while the underlying cause of the shock is treated.
Complete tissue perfusion with RNA-later after total pancreatic tissue dissection is not cost-effective.
(4) These signs include both biochemical and clinical parameters and are grouped in four categories: general, inflammatory, hemodynamic, and tissue perfusion parameters.
