What is blood pressure

Blood pressure

Blood pressure is exerted by the blood against the wall of blood vessels as it lows trough them.

Systolic blood pressure

Systolic blood pressure is the highest degree of pressure Exerted by the blood against the walls of blood vessels during the ventricular systol when the left ventricle is forcing the blood into aorta.

Diastolic blood pressure

It is the lowest pressure that occour when the heart is in resting period just befor the contraction of the left ventricle.

Pulse pressure 

It is the defference between the systolic blood pressure and diastolic blood pressure.

It is represent the volume out put of left ventricle.

Normal adult blood pressure = 120/80mmhg

Measuring unit = mmHg 

 Instruments = sphygmomanometer 

Normal blood pressure sound = korar koff sound

Blood regulation center = medulla oblongata.

Normal ratio of systolic , diastolic , pulse pressure = 3:2:1 

Mean arterial blood pressure

Diastolic +1/3(pulse pressure ) = MABP 

Some variation in blood pressure 

Normal b.p = 120/80mmhg

Peripheral tension = 120-139/80-89

Hypertension = 140/90 or more 

Hypertension crisis= 200/110 mmHg 

Shock = systolic BP below 90 mmHg 

Factor effecting blood pressure 

1)Age = children have less blood pressure then the old age person.

2) sex = Befor puberty boy and girl have same blood pressure but after puberty male have High blood pressure then the female .

3) body build = Higher in over weight person of same age group.

4) Time of the day = 

        Night < morning < evening 

5) Exercise = Muscular exercise will rise the BP.

6) pain = sever pain may couse temporary increase in blood pressure.

7) Emotion = Fear, excitement, anxiety. 

8) posture = standing < sitting < lying 

9) Drugs = some drugs decrease blood pressure like Antihypertension .

And some drugs increase blood pressure like dopamine.

10) Hemorrhage 

11) Disease condition = hypothyroidism

Side for taking blood pressure

Mid arm measuring cuff size= brachial artery.

Mid thigh measuring cuff size = poplitial artery

Mid tibial measuring cuff size = Dorsalpedalis artery.
