Opinion only: A Nicardipine intravenous bolus dosing can be used for acutely decreasing arterial blood pressure during general anesthesiafor Cardiac operations; however, has no effects on ventricular preload or cardiac output. If you would like further information on this topic, I have added a web link to the American Heart Association that is displayed directly below this window.
What else can I help you with?
What do plasma proteins that remain in the blood capillaries help?
Maintain the osmotic pressure of the blood
What is the effect of a fluid bolus on blood pressure and heart rate?
It will increase blood pressure by increasing volume. This will have a negate chromotropic effect and decrease HR.
When do you give a fluid bolus followed by a epidural?
A fluid bolus is typically administered before an epidural to ensure adequate hydration and maintain blood pressure, especially in laboring patients. This is particularly important because epidurals can cause vasodilation and hypotension. A common practice is to give a bolus of 500-1000 mL of isotonic fluid prior to the epidural placement to minimize the risk of maternal hypotension. After the fluid bolus, the epidural can be safely administered.
What is the effect of hypovolemic shock on the blood vessels and the heart?
Blood vessels constrict to increase venous return and maintain pressure. Heart rate increases to compensate for loss of blood pressure and to maintain cardiac output.
What is the component of plasma that maintains the osmotic pressure of blood?
The component of plasma that maintains the osmotic pressure of blood is protein. The protein albumin and others maintain osmotic pressure in blood.
How the human heart could compensate for flow rate changes to maintain blood pressure?
The human heart could compensate for flow rate changes to maintain blood pressure by setting the pace at which it beats and maintains blood flow. When a heart rate increases, blood pressure will rise, and when a heart rate decreases, blood pressure will drop.
Plasma proteins that remain in the blood capillaries help to?
Maintain the osmotic pressure of the blood.
Which element help maintain healthy blood pressure?
magnesium
How does venous circulation help to maintain blood pressure when hemorrhaging causes blood loss?
carefully
How do arteries respond to sudden blood loss?
They constrict in order to try and maintain blood pressure.
Which type of blood vessel exhibits elastic recoil to maintain diastolic blood pressure?
Arteries!
Why is it important that the veins contain valves?
to maintain blood flow and pressure
