Blood pressure

How to measure blood pressure.

3. Blood pressure (BP) is the
pressure or tension exerted
on the arterial walls as blood
pulsates through them.

5. Is a pressure exerted on the
arteries during the
contraction phase of the
heartbeat.
SYSTOLIC
BLOOD
PRESSURE
(SBP)

6. Is the resting pressure on the
arteries as the heart relaxes
between contractions.
DIASTOLIC
BLOOD
PRESSURE
(DBP)

10. PURPOSES OF TAKING
B/P
•To obtain baseline data for subsequent
evaluation.
•To determine haemodynamic status ( e.g.
cardiac output ).
•To identify and monitor changes in blood
pressure resulting from disease process or
medical therapy ( e.g. rapid infusion or pain ).

13. –Brachial – taken on the upper arm;
most common site.
–Radial – taken on the lower arm;
possible site for infants or clients who
have very large upper arms.
–Popliteal – taken on the thigh.
–Dorsalis pedis and posterior tibial –
taken on the lower leg.

15. CONDITION OF B/P
CANNOT BE TAKEN
•Shoulder, arm or hand injured.
•A cast or bulky bandage on the limb.
•Had surgical removal of axillary gland
or lymph nodes.
•Has intravenous infusion in that limb.
•Has arteriovenous fistula ( AVF ) in that
limb.

patient

38. POST PROCEDURE

48. PROCEDURE
•Wrap the cuff 2.5 cm above the antecubital
area

49. PROCEDURE
•Wrap the cuff evenly & firmly around upper
arm

50. PROCEDURE
•Ensure manometer is positioned straight & at
eye level

51. PROCEDURE
•Palpate radial pulse & pump until no pulse is
felt to estimate PRELIMINARY systolic
pressure

52. PRELIMINARY SYSTOLIC BP
READING

53. PROCEDURE
•Deflate the cuff fully

54. PROCEDURE
•Clean stethoscope earpieces & diaphragm,
place earpieces into ears & ensure sound are
clear & not muffled

56. PROCEDURE
•Place diaphragm over the brachial pulse

57. PROCEDURE
•Pump cuff 20-30mmHg above previous
preliminary systolic readings

58. PROCEDURE
•Slowly deflate cuff & listen to both systolic &
diastolic reading

62. POST PROCEDURE
•Perform hand hygiene

63. POST PROCEDURE
•Inform SRN or doctor abnormal result

64. POST PROCEDURE
•Document reading

67. HYPERTENSION
•A BLOOD PRESSURE
PERSISTENTLY ABOVE NORMAL
RANGE.
•B/P > 140/90 mmHg.

73. HYPOTENSION
•BLOOD PRESSURE BELOW
NORMAL RANGE CONSISTENTLY.
•B/P < 90/60mmHg.

74. A drop in blood pressure may
indicate:
– Loss of blood
– Loss of vascular tone
– Cardiac pumping problem
