What are the two types of arterial pressure?

Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.

What is narrow and wide pulse pressure?

The normal pulse pressure is 30-40 mmHg. A pressure that exceeds this is called a wide pulse pressure. A pressure that is smaller than this (<25 mmHg) is a narrow pulse pressure.

What is the difference between pulse pressure and mean arterial pressure?

Pulse pressure (PP), defined as the difference between systolic blood pressure (SBP) and diastolic blood pressure (DBP), is a pulsatile component of the blood pressure (BP) curve as opposed to mean arterial pressure (MAP), which is a steady component.

What is an example of narrow pulse pressure?

Narrow pulse pressures occur in several diseases such as heart failure (decreased pumping), blood loss (decreased blood volume), aortic stenosis (reduced stroke volume), and cardiac tamponade (decreased filling time).

What is CVP?

Central venous pressure (CVP) is the pressure in the thoracic vena cava near the right atrium. CVP is an important factor in critical care medicine because it can be used to estimate a patient’s fluid volume status, assess cardiac function, and gauge how well the right ventricle of the heart is functioning (1).

What is widening pulse pressure?

A wide pulse pressure — sometimes called a high pulse pressure because the number is greater — means there’s a wide difference between the top and bottom numbers. For individuals who aren’t physically active, wider pulse pressures can indicate serious problems either now or in the future.

Why is PDA wide pulse pressure?

A widened pulse pressure (> 30mmHg) occurs both because of a mild increase in systolic blood pressure to overcome the decrease in distal blood flow due to run-off through the PDA during diastole, in addition to a lower diastolic blood pressure from the run-off.

What is difference between systolic and diastolic pressure?

Blood pressure readings are given in two numbers. The top number is the maximum pressure the heart exerts while beating (systolic pressure). The bottom number is the amount of pressure in the arteries between beats (diastolic pressure).

What is another name for pulse pressure?

Pulmonary (Heart-Lung) pulse pressure (PAP) is normally a lot lower than systemic blood pressure. It is measured by right heart catheterization or may be estimated by transthoracic echocardiography (TTE) Normal pulmonary artery pressure is between 8mmHg -20 mm Hg at rest.

What is the formula for pulse pressure?

The top number (systolic) minus the bottom number (diastolic) is the pulse pressure. For example, if the resting blood pressure is 120/80 millimeters of mercury (mm Hg), the pulse pressure is 40 — which is considered a healthy pulse pressure.

What is a widening pulse pressure?

A high pulse pressure is sometimes called a wide pulse pressure. This is because there’s a large or wide difference between the systolic and diastolic pressure. A low pulse pressure is a small difference between your systolic and diastolic pressure.
