Non-Invasive Blood Pressure
GE offers quality blood pressure cuffs for every patient, every size, every department. CRITIKON® products are backed by more than 25 years of excellence in blood pressure cuff manufacturing and ongoing research and development.

GE has a full offering of adapters and connectors for whole-hospital conversion. By standardizing your connectionsystem, you create a universal connection that allows the same cuff connection to work on a variety
1.1. What is blood pressure?
Arterial blood pressure is the force exerted by the blood on an area of the wall of an artery as it is pushed through the circulatory system. During the course of the cardiac cycle, the arterial blood pressure is constantly changing . As the heart beats, the highestpressure in this cycle (systolic blood pressure) is recorded. Between beats, the lowest pressure (diastolic blood pressure) is recorded. The systolic number is always stated first and the diastolic number is listed second.
For example: 122/76 (122 over 76); systolic = 122, diastolic = 76.
Blood pressure is determined by a number of factors including:
* Cardiac output
* Peripheral vascularresistance
* Volume of blood in the arterial system
* Viscosity (density) of the blood
* Elasticity of the arterial walls

The exact contribution of each factor is not known, but peripheral resistance and cardiac output have the greatest influence on blood pressure.
Blood pressure is stated as millimeters of mercury (mmHg), patterned after the early measurement equipment. The firstnumber stated is the systolic, whereas the second number is the diastolic. Thus, 120/80 mmHg is often abbreviated as 120 over 80.

1.1.2 Systolic Blood Pressure
Measurement of the pressure when the heart is contracted (systole). The systolic pressure indicates the maximum amount of work/force the heart has to perform with each stroke in order to move blood through the arteries 13. It also mayindicate how compliant the arteries are in order to accommodate blood; it indicates how "elastic" they are
Systolic pressure is the force of blood in the arteries as the heart beats. It is shown as the top number in a blood pressure reading. High blood pressure is 140 and higher for systolic pressure. Diastolic pressure does not need to be high for you to have High Blood Pressure. When thathappens, the condition is called “isolated systolic hypertension,” or ISH.
systolic blood pressure increases with age, while diastolic increases until about age 55 and then declines. About 65 percent of hypertensives over age 60 have ISH.

1.1.3 Systolic Blood Pressure
Referring to the time when the heart is in a period of relaxation and dilatation (expansion).
The noun for diastolic is diastole.(The final letter in "diastole" is pronounced as a long "e" as in "lee.")
The diastolic pressure is specifically the minimum arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood.
In a blood pressure reading, the diastolic pressure is typically the second number recorded. For example, with a blood pressure of 120/80 ("120 over80"), the diastolic pressure is 80. By "80" is meant 80 mm Hg (millimeters of mercury).
A diastolic murmur is a heart murmur heard during diastole, the time the heart relaxes.

Comparison chart
| Diastolic | Systolic |
Blood Pressure: | Diastolic represents the minimum pressure in the arteries. | Systolic represents the maximum pressure exerted on the arteries. |
Blood pressure reading: |The lower number is diastolic pressure. | The higher number is the systolic pressure. |
Ventricles of the heart: | Fill with blood | Left ventricles contract |
Definition: | It is the pressure that is exerted on the walls of the various arteries around the body in between heart beats when the heart is relaxed. | It measures the amount of pressure that blood exerts on arteries and vessels...
