Yes, blood pressure readings can vary between the left and right arms due to differences in blood vessel constriction. This is known as the inter-arm blood pressure difference. It is important to measure blood pressure in both arms to detect any significant differences that may indicate underlying health issues.
Diastolic blood pressure is the lower number in a blood pressure reading, representing the pressure in the arteries when the heart is at rest between beats. It is an important measure of heart health and can indicate the pressure on the arteries during relaxation of the heart muscle.
Diastolic pressure is the bottom number in a blood pressure reading, indicating the pressure in the arteries when the heart is at rest between beats. It represents the minimum pressure in the arteries during the cardiac cycle. A normal diastolic pressure is typically less than 80 mmHg.
Arterial blood pressure is typically measured using a blood pressure cuff and a sphygmomanometer. The cuff is inflated to a pressure higher than the arterial pressure, then slowly deflated while listening for the sound of blood flow through the artery using a stethoscope. The two values measured are systolic pressure (when the heart is contracting) and diastolic pressure (when the heart is relaxed).
Aneroid sphygmomanometers are used to measure blood pressure. They consist of a cuff that is wrapped around the upper arm, a pressure dial that displays the pressure reading, and a stethoscope to listen to the blood flow sounds.
The first number in a blood pressure reading is the systolic blood pressure. It represents the pressure in the artery when the heart is contracting. The second number is the diastolic blood pressure, and represents the pressure when the heart is relaxing.
Because blood pressure changes.
Pulse pressure is the difference between the systolic and diastolic blood pressure readings.
The normal blood pressure is usually between 120-140 mm Hg (systolic) and 80 - 90 mm Hg (diastolic). Anything higher will be considered as high blood pressure
The blood pressure measured when the ventricles relax is called diastolic blood pressure. It is the lower number in a blood pressure reading, representing the pressure in the arteries when the heart is at rest between contractions.
Systolic (the higher number) is a reading of the pressure in your blood vessels when your heart is beating at its maximum strength. Diastolic (the lower number) tells you what the pressure is in your blood vessels when your heart is at rest.

Arterial pressure
The upper reading is the systolic blood pressure while the lower reading is the diastolic blood pressure. Systole is the contraction of the heart while diastole is the relaxation of the heart.
Blood pressure
A blood pressure reading of 122/66 mmHg indicates a systolic pressure of 122 mmHg (pressure in the arteries when the heart beats) and a diastolic pressure of 66 mmHg (pressure in the arteries when the heart is at rest between beats). This reading falls within the normal range for blood pressure.

Diastolic blood pressure is the lower number in a blood pressure reading, representing the pressure in the arteries when the heart is at rest between beats. It is an important measure of heart health and can indicate the pressure on the arteries during relaxation of the heart muscle.
