What is the difference between venous blood pressure and arterial blood pressure?

What is the difference between venous blood pressure and arterial blood pressure?

See Below: Venous blood pressure is in the venous system and usually should not exceed 5-8 mmhg. The venous system takes de-oxygneated blood back to the heart. Arterial blood pressure is in the arteries, ie taking oxygen to the body, and is usually more than 70 mmhg for the diastolic and 130mmhg for the systolic. ...Read more

Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

I wanted to know is capillary blood a mixture of arterial blood and venous blood?

I wanted to know is capillary blood a mixture of arterial blood and venous blood?

Not exactly: Capillaries are situated between the arteries and veins and capillary blood does have characteristics half between the arterial and venous blood.
For good health — Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

When would you look at cord venous blood gas levels and arterial blood gas levels?

When would you look at cord venous blood gas levels and arterial blood gas levels?

Difficult delivery: These tests are used to help predict how difficult the delivery was for the baby. Any difficult delivery will often have cord gases taken; if baby is showing signs of distress, then an arterial blood gas from baby may be taken as well. ...Read more

Hi doctors, was just wondering what is an arterial blood pressure in medical terms?

Hi doctors, was just wondering what is an arterial blood pressure in medical terms?

Whay you measure: When you take your BP either at home or in one of those automated pharmacy units it is measuring the systolic (heart contracting and arteries) as well as diastolic in the arterial system not in your veins but your arteries. The vessels that carry blood from the heart to the body ...Read more

Please explain why is pulmonary arterial blood pressure less than systemic arterial blood pressure?

Please explain why is pulmonary arterial blood pressure less than systemic arterial blood pressure?

PAP: The resistance to flow of blood is much lower in the lung than in the systemic circulation, this is why the pa pressure is normally lower than systemic pressure, the blood flow in both circuits is normally the same and pressure equals flow times resistance. ...Read more

What is more accurate. Arterial blood pressure invasive through the artery or a stethoscope?

What is more accurate. Arterial blood pressure invasive through the artery or a stethoscope?

Depends on situation: Normally the Sphygmomanometer is used to take a blood pressure, which may or may not use a stethoscope. It is accurate, as long as there is no blockage and there is no condition to cause the arteries to narrow. Arterial monitoring using a catheter is certainly more accurate, but also subject to the same limitations of artifact, but is used in conditions with critically ill patients. ...Read more

Which has higher co2, cord arterial blood gas or venous?

Which has higher co2, cord arterial blood gas or venous?

The non-red blood: In the cord I forget which one has the oxygen, but that has the good air and not the bad air. I'm pretty sure it works reasonably with arterial going IN with oxygen and nutrients and coming back out with wastes and CO2. ...Read more

Arterial blood gases, very low oxygen levels found, what to do?

What is the level: If that's you, it must be wrong since you would not be thinking enough to be here, consider venous blood. On the other hand if it is someone else, then that person needs oxygen either by cannula, mask or even a ventilator. ...Read more

Why would keto-acidosis lead to decreased pco2 in arterial blood gases?

Why would keto-acidosis lead to decreased pco2 in arterial blood gases?

Compensation: In response to the low ph caused by the ketoacidosis, the brainstem triggers a dramatic increase in the respiratory rate. This causes the lungs to expel more carbon dioxide in a process known as respiratory compensation for metabolic acidosis. ...Read more

Arterial blood gases, very low oxygen levels found in my baby. Will he have cp?

Hard to say: The fetus has low oxygen levels compared to the rest of us for the duration of the pregnancy. Any lab value must be put in context with what is happening. How low, for how long and with what other abnormalities provides a better predictive value. For some premi's, they try to keep it in a lower zone to help prevent eye damage caused by too high oxygen levels while the eyes are developing. ...Read more

2 weeks ago my blood pH level was -11 the doc tried to take arterial blood gases but couldn't. He was confused by -11 pH level. What could cause it?

2 weeks ago my blood pH level was -11 the doc tried to take arterial blood gases but couldn't. He was confused by -11 pH level. What could cause it?

PH: PH range runs only from 0 (very acidic) to 14 (very basic/alkali). The body's normal pH is right around 7.35ish. I am confused by the -11 reading as well as there is no such possibility to have that as a result. Maybe it was a result of equipment malfunction, or an error message by the computer ...Read more

Can high o2 affinity hemoglobin cause arterial blood gas values of high o2?

Can high o2 affinity hemoglobin cause arterial blood gas values of high o2?

Less O2 delivery: High o2 affinity HGB (leftward shift in o2 saturation curve) means it requires a higher partial pressure of o2 to achieve the same o2 saturation. The HGB is more tightly bound to o2 and less is delivered to the tissues. More o2 will be necessary to adequately deliver oxygen to the tissues. ...Read more

How does sleep apnea affect arterial blood gas?

How does sleep apnea affect arterial blood gas?

Can temporarily lower 02: When someone is having apnea they stop breathing and this can cause a decrease in the blood oxygen and an increase in the blood carbon dioxide. Once they start breathing again usually this corrects itself fairly quickly. ...Read more

Arterial blood gas, what is this?

Arterial blood gas, what is this?

Mearsurment: THe sampling of blood from an artery gives the tester a clue as to how much oxygen your cells are carrying, the level of Co2 to see if respiration and acid base balance is in check. ABG is often performed during asthma to see the pulmonary status and whn one is on a ventilatr to breathe. It can ensure the ventilator is producing enough ventialtion ...Read more

What ia an? Arterial blood gas exam?

Blood oxygen test.: An abg is a test that measures the oxygen tension, carbon dioxide, and acidity (ph) of blood taken from an artery. It is used to determine how well the blood is being oxygenated and how well gas exchange is occuring. This information is vital when caring for patients with critical illness or respiratory disease. ...Read more

Blood Gases: I am not sure what context you are asking about. The questions is very ambiguous. What specifically prompts this question?

But, blood gases tell the medical team how well the oxygen and carbon dioxide balance is being maintained in the body. It can tell how the fragile balance of being acidic or basic is in a sick person. It is used in many instances in the hospital with very ill patients. ...Read more

Blood Pressure (Definition)

Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
