Why packed cells volume higher in venous than arterial?
This situation happen because VOLUME OF RBCs in venous blood is high. The volume is increased from arterial blood to venous blood because chloride shift that occurred;relate with increase of carbon dioxide in blood.
What determines the rate of blood flow?
Heart rate and stroke volume, since CO=HR*SV
Does increasing arterial blood pressure increases blood flow?
YES! Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end - diastolic pressure and volume. This increase in ventricular preload increases ventricular stroke volume by the Frank - Starling mechanism. An increase in right ventricular stroke volume increases pulmonary venous blood flow to the left ventricular, thereby increasing left ventricular preload and stroke volume. An increase in stroke volume then increases cardiac output and arterial blood pressure. answered by HappyNess0423
What is the best sample for the determination of blood pH and blood gases?
arterial blood
What does arterial mean as in arterial o2 saturations?
Arterial is a reference to the blood in the arteries, as opposed to blood in the veins.
What does ABGs stands for?
It can mean Arterial Blood Gas.
In which type of bleeding is blood less likely to clot?
An arterial bleed, because the blood is flowing at a high rate of speed/pressure.
What does arterial pressure reflect?
An individual's blood pressure is dependent on several factors including genetics, weight and stress levels. While there is nothing we can do to change our genetics one can eat a healthy diet and manage stress in an attempt to control blood pressure.
What Conditions affect mean arterial pressure?
Some conditions affecting mean arterial pressure, or MAP, blood pressure, heart rate, resistance to blood flow in the vessels, and cardiac output which is the volume of blood pumped out by the heart. Increasing or decreasing any of the can change your mean arterial pressure and cause consequences to the organs in the body.
Arterial blood pressure increases in response to?
Two of the main factors that influence blood pressure is cardiac output and blood volume. Another factor is the peripheral resistance.
Arterial blood is what color?
Arterial Blood is Bright Red
What Mechanisms that cause changes blood volume to fingertips?
Studies have found that respiration can alter the blood volume levels to the fingertips. When inhaling the blood volume levels can increase whilst the blood levels can decrease in the fingertips when exhaling. This is because respiration causes fluctuations in arterial blood pressure and heart rate.
