Question

Vital Signs .1. Match the following

Korotkoff _______

Systolic _______

Diastolic _______

Anasarca _______

PMI _______

MAP _______

1. The minimum arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood.

2. Edema, a medical condition characterized by widespread swelling of the skin due to effusion of fluid into the extracellular space.

3. The average pressure in a patient's arteries during one cardiac cycle. It is considered a better indicator of perfusion to vital organs than systolic blood pressure (SBP)

4. Arterial sounds heard through a stethoscope applied to the brachial artery distal to the cuff of a sphygmomanometer that change with varying cuff pressure and that are used to determine systolic and diastolic blood pressure.

5. The maximum arterial pressure during contraction of the left ventricle of the heart.

6. The apex beat which is the point on the precordium farthest outwards (laterally) and downwards (inferiorly) from the sternum at which the cardiac impulse can be felt.

2. How do you calculate the MAP?

Answer 1

1)

Korotkoff - 4 Arterial sounds heard through a stethoscope applied to the brachial artery distal to the cuff of a sphygmomanometer that change with varying cuff pressure and that are used to determine systolic and diastolic blood pressure.

Systolic - 5 The maximum arterial pressure during contraction of the left ventricle of the heart.

Diastolic - 1 The minimum arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood.

Anasarca - 2 Edema, a medical condition characterized by widespread swelling of the skin due to effusion of fluid into the extracellular space.

PMI (point of maximal impulse) -6 The apex beat which is the point on the precordium farthest outwards (laterally) and downwards (inferiorly) from the sternum at which the cardiac impulse can be felt.

MAP (Mean arterial pressure) - 3 The average pressure in a patient's arteries during one cardiac cycle. It is considered a better indicator of perfusion to vital organs than systolic blood pressure (SBP).

2) MAP (Mean arterial pressure) is calculated by first doubling the value of diastolic ,then adding to the value of systolic and finally dividing by 3.

example - a person's blood pressure is 120/80 here the systolic is 120 and diastolic is 80. To calculate MAP

first double the diastolic so   

80 x 2 = 160

second add this value to systolic

160 +120 = 280

finally dividing this value by 3 mmHg

380;3=933

so this patient's MAP (Mean arterial pressure) is 93.3 mmHg.
