Clogged blood pressure - symptoms and causes

Vascular blood pressure is calculated as systolic blood pressure minus diastolic pressure. The normal value is 40mmHg. Each variability in vascular blood pressure has a distinct clinical significance. Determination of vascular blood pressure is very complicated. The decisive factors were arterial resistance, artery properties and stroke volume / cardiac output.

Description

Is blood pressure less than 20mmHg vessels

Reason

Common

Heart failure.

Aortic stenosis.

Shock reduced volume.

Rarely

Hypertrophic cardiomyopathy.

Mitral valve stenosis.

Mechanism

It must be remembered that the systolic pressure is the largest pressure in the systolic, while the diastolic pressure is the smallest pressure in the artery, the diastole. Reduced cardiac output and increased systemic resistance are the most common pathways for blocked blood pressure.

In practice, this means that any condition that reduces cardiac output (systolic blood pressure) with arterial resistance is kept intact, causing blood pressure to jam.

Heart failure

In heart failure, low stroke volume leads to increased sympathetic reflexes and increased vascular resistance to maintain blood pressure and help venous blood return to the heart. Thus, a low systolic pressure (due to a decrease in cardiac output) and diastolic blood pressure is maintained (due to increased vascular resistance), creating jammed blood pressure.

Shock

In the early stages of hypovolemic shock, catecholamine concentrations are high as the body tries to increase peripheral resistance to maintain venous blood return to the heart. The increase in peripheral resistance increases diastolic blood pressure, and as a result, block blood pressure.
