Delirium (Definition)

We believe delirium occurs when the brain cannot maintain its normal activities when overwhelmed by metabolic demands or other variables which exceed the brain's capacity to compensate for. Brains with less reserve capacity are particularly vulnerable. Not entirely unlike acute heart failure. See my last textbook chapter for more reading in the appi textbook ...Read more

Can dehydration cause cardiac arrest?

Can dehydration cause cardiac arrest?

Dehydration: Severe dehydration and increase the viscosity of the blood (make it more sluggish). The average normal person will tolerate this. If there is underlying limitation of blood flow to the heart (blockage in the arteries), problems could arise. ...Read more

Why?Would someone in renal failure have decreased cardiac output?

Why?Would someone in renal failure have decreased cardiac output?

Many reasons: Decreased cardiac output can contribute to reduced kidney function. Kidney disease is often associated with heart problems that reduce cardiac output. High blood pressure and volume overload with kidney failure can also reduce heart output. It's often difficult to sort out cause and effect in these situations. ...Read more

How can decreased cardiac output be caused by increased fluid volume ?

How can decreased cardiac output be caused by increased fluid volume ?

You have it reverse: Heart rate x stroke volume = cardiac output and thus if stroke volume decreases, cardiac output decreases or if heart rate decreases cardiac output decreases. ...Read more

How could hypertension affect cardiac output?

How could hypertension affect cardiac output?

Two ways: It can cause the heart muscle to get thick and stiff so that it does not relax and fill up with blood properly. It could also cause the heart muscle to become weak so that it does not squeeze or contract as forcefully. These are called diastolic dysfunction (too thick) or systolic dysfunction (weak and flabby). ...Read more

How can decreased cardiac output be caused by abnormal fluid volume?

How can decreased cardiac output be caused by abnormal fluid volume?

Overloading: Low cardiac function may not be able to keep up with too much volume and the fluid backs up in places like the lung, neck, abdomen, and legs. Too much volume can overwhelm a borderline heart already weak. When the heart cannot keep up the needed cardiac output (liters per min) and making the pump work harder increasing pressure inside the heart, and dilating the chamber getting into a bad cycle. ...Read more

How could hyperthyroidism affect cardiac output?

How could hyperthyroidism affect cardiac output?

Hyperthyroidism: Hyperthyroidism is a excess metabolic state. If other systems are normal it will usually cause increased heart rate and cardiac output. In the face of a weak heart, it could be associated with decrease in cardiac output. Chronic hyperthyroidism can be associated with a cardiomyopathy causing decreased heart function. ...Read more

How could venoconstriction affect cardiac output?

How could venoconstriction affect cardiac output?

Venoconstriction?: Cardiac output is inversely proportional to total peripheral resistance (which is related to mean arterial pressure.) venoconstriction refers to the venous system and can't be measured. If venous return increases, preload increases, and by starling's law of the heart, cardiac output increases. However, severe venoconstriction could eventually diminish venous return and reduce co.

Does heart failure cause sleepiness?

Does heart failure cause sleepiness?

Yes, it can: Heart failure can certainly cause profound fatigue and weakness, and even increased sleepiness. This is usually as a result of limited forward blood flow out of the heart, for instance to skeletal muscles (limits activity tolerance), the brain and so on. It's also very common for people with heart failure to develop sleep apnea, making their sleep quality suffer and leading to daytime sleepiness. ...Read more

How could vasoconstriction affect cardiac output?

How could vasoconstriction affect cardiac output?

It lowers it: Vasoconstriction increases the resistance to flow. This is called an afterload. It is like a pump having to pump water up a steep hill; it won't pump as well as on flat land. ...Read more

Does hypoxia by itself lead to cardiac arrest?

Does hypoxia by itself lead to cardiac arrest?

Potentially: Hypoxia means an inadequate amount of oxygen in the blood. Is can lead to vital organs not receiving enough oxygen to survive. If the heart is starved for oxygen this can lead to ischemia or heart cell death which can cause either failure or an abnormal rhythm which leads to a cardiac arrest. ...Read more

Can you tell me how propofol may cause heart dysfunction leading to cardiac arrest?

Can you tell me how propofol may cause heart dysfunction leading to cardiac arrest?

Anesthesia: Propofol is an anesthesia. It goes to the brain, and depresses the breathing center. This causes hypoxia to all tissues including the heart. The hypoxia also causes acidosis from anaerobic respiration, and vasodilatation and drop in bp. This all lead to hypoxia of tissues including heart muscles, and eventual death of tissues. ...Read more

What factors can affect cardiac output?

What factors can affect cardiac output?

Cardiac output: In strict physiologic terms, cardiac output is determined by something called stroke volume and heart rate. Heart rate is self-explanatory. Stroke volume is the amount of blood that the heart pumps out with each beat. This in turn is dependent on blood pressure, total blood volume, and how strong the heart contracts. ...Read more

What is meant by decreased cardiac output related to left ventricular failure?

Sick muscle: The heart is supposed to pump out a certain amount with every heart beat, if that amount is too low, e.g. Low out put, the heart muscle is too weak to do it's job(failure). ...Read more

Why does a patient in renal failure have decreased cardiac output?

Not always related: Renal failure in and of itself is not realted to cardiac output, there are many things that can cause both renal failure and decreased cardiac output, but they are not always related. However if someone has really low cardiac output, one could develop renal failure b/c not enough blood is getting to the kidneys. ...Read more
