How does a nurse assess perfusion?
Inspection. Skin color to assess perfusion. Inspect the face, lips, and fingertips for cyanosis or pallor. Cyanosis is a bluish discoloration of the skin, lips, and nail beds and indicates decreased perfusion and oxygenation.
How do you assess tissue perfusion in a patient?
Evaluation of tissue perfusion can be done by considering gum or lip mucous membrane colour, the capillary refill time, and the blood pressure. High mean arterial pressure does not guarantee adequate tissue perfusion.
What is the best indicator of tissue perfusion?
Lactate is the most frequently used marker of tissue perfusion [6]. Lactic acidosis is a predictor of in-hospital mortality in septic shock [7, 8]. Increased lactate clearance during resuscitation of septic shock was associated with improved outcomes [9].
What are signs of poor perfusion?
The body's circulation system sends blood and oxygen throughout your entire body. Poor circulation, also known as poor perfusion, occurs when blood flow to a specific part of your body is reduced....Common Symptoms of Poor CirculationTingling and Numbness. ... Coldness. ... Muscle Cramps. ... Swelling.
What is cardiac tissue perfusion?
Myocardial tissue perfusion is the myocardium's ability to extract oxygen and nutrients from the bloodstream. Maintenance of a normal capacity depends on arterial coronary blood flow, free of stenosis, in addition to arterial oxygen content, blood volume, cardiac output, and duration of diastole (Braunwald, 2005).
What is peripheral tissue perfusion?
Peripheral perfusion index is defined as the difference between the pulsatile and non-pulsatile portion of pulse wave, measured by plethysmography. Peripheral perfusion index (PPI) gives information on peripheral vascular tonus by the pulsatility, decreasing in vasoconstriction and raising in vasodilation [42].
What is ineffective tissue perfusion evidenced by?
ineffective Tissue Perfusion (specify) may be related to hypovolemia and vascular pooling (vasodilation), and is possibly evidenced by diminished pulse, pallor or cyanosis, hypotension, and changes in mentation.
What is impaired tissue perfusion?
Causes of Impaired Tissue Perfusion Any condition that limits blood flow can cause reduced perfusion to vital organs and distal extremities. This reduced blood flow can result in tissue death, leading to organ damage, loss of limb, or even patient death.
Pump – the heart
The average adult heart contracts between 60 and 100 times per minute. The stroke volume of each ventricular contraction averages 70 milliliters. Stroke volume is determined by preload (how much blood is available to fill the ventricle before contraction) and myocardial contractility.
Pipes – the blood vessels
Normal blood pressure equals good perfusion (even though there are numerous debates as to what “normal” is). Determining blood pressure is trickier, in the sense that you take the average cardiac output and multiply that value to the afterload.
Plasma – the blood
Viscosity of the blood is the other variable that determines afterload. Perfusion deteriorates as viscosity increases. In other words, the more concentrated the blood, the higher the resistance, and the slower the flow. Think of it this way: You have a cup containing plain water and another cup containing a milkshake.

Perfusion
Perfusion is the process of oxygenated blood being delivered to the tissues of the body. To understand when perfusion occurs, we need to define a few terms of the heart beat cycle first. A heart beat is made up of two cycles. Systole is the first cycle, also called the 'lub,' and is when the chambers contract and force blood into the arteries.
Treatment
Think about the plumbing in your home. Let's imagine the arteries are the pipes in your house, the tissues are the faucets, the blood is the water, and the heart is the main water valve outside. If you turned on your faucet and no water came out, what would you do? You'd probably check to make sure water is being supplied to your house.
Goals and Outcomes
The following are the common goals and expected outcomes for this nursing problem:
Nursing Assessment
Regular assessment is required in order to identify possible problems that may have lead to ineffective tissue perfusion as well as name any situation that may happen during nursing care. Here are some assessment cues you may need for creating a nursing care plan (NCP) for ineffective tissue perfusion:
Nursing Interventions
The following are the therapeutic nursing interventions for ineffective tissue perfusion:
Patient monitoring and clinical measurement
Evaluation of tissue perfusion can be done by considering gum or lip mucous membrane colour, the capillary refill time, and the blood pressure. High mean arterial pressure does not guarantee adequate tissue perfusion.
Shock
In 1872 the trauma surgeon Samuel D. Gross defined shock as “the rude unhinging of the machinery of life.” Shock is the progression of a cascade of events that begins when cells or tissues are deprived of an adequate energy source (oxygen).
