1What Every Tech Should Know About Blood Pressure? Lynn Lawrence, CPOT, ABOC
2What is Blood Pressure? It can be a vascular disease The pressure that blood inside the vessels are exerting on the walls of the vesselsCan be constant or intermittent
3Blood PressuresSystolic – Pressure exerted on your vessels when the heart contracts and is pumping bloodDiastolic - Pressure exerted on your vessels when the heart is at restThese can change throughout the day and activities have an impact too
4Anatomy of the Heart Right Atria Left Atria Right Left Ventricle Blood is pumped from the Right Atria to the Right Ventricle, through the pulmonary vein to the lungs. It then returns to the heart through the Left Atria to the Left Ventricle and is then pumped to the rest body through the Aorta.RightVentricleLeftVentricle
6Healthy Life Styles Changes Reducing body weightRestricting dietary saltDecreasing fatNot smokingAvoiding excess alcoholExercising regularlyDeveloping relaxing techniquesTaking medication as prescribe
7What is Hypertension? It is the same as high blood pressure When your blood pressure is high, your heart must work harder to pump the same amount of blood through your arteriesThis can damage your heart, kidneys, vessels and eyesMajor cause of cerebrovascular accident (stroke), cardiac disease, and renal failure
82 Types Primary is the most common type and it’s cause are unknown. Secondary may be the result of renal vascular disease, renal parenchymal disease, Cushing’s syndrome, DM, dysfunction of the thyroid or adrenal gland, pregnancy, and some neurologic disorders
9Symptoms of Hypertension Head achesBlurred visionChest painFrequent night urinationNose bleedsDizziness/fatigueStroke…sudden death of tissueHeart attackHypertensive retinopathy, hemorrhage, exudates, papilledema, subconjunctival hemorrhages
10QuestionWhy is high blood pressure dangerous to a diabetic patient?
11Question Why is high blood pressure dangerous to a diabetic patient? a. Diabetes is a vascular disease and high pressure through weaken vessels is a bad combination
12The kidneys play what role in blood pressure? QuestionThe kidneys play what role in blood pressure?
13Question The kidneys play what role in blood pressure A. Aids in maintaining pressure and volume by vasoconstriction, regulation of sodium, and fluid levels
14Why is it important to ask about BP during a screening? QuestionWhy is it important to ask about BP during a screening?How about the family Hx?
15Should I take blood pressure before or after I dilate my patient. Why? QuestionShould I take blood pressure before or after I dilate my patient. Why?
18Taking a Blood Pressure Have the patient relax 20 minutesArm should be at heart levelPlace the Blood Pressure Cuff on the armAbove the elbow over the Brachial Artery
19Taking a Blood Pressure Select the correct cuff sizeHave the patient relax their arm.Find the Radial pulse.
20Taking a Blood Pressure Inflate the blood pressure cuff until you can no longer feel a pulse.Then inflate 30mmHg more.At least 200mmHg
21Taking a Blood Pressure Place your stethoscope over the brachial artery.Begin deflating the cuff slowly until you hear the pulse return.This is your Systolic Pressure.
22Taking a Blood Pressure Listen until you no longer hear a pulse.This is the Diastolic Pressure.
23Abnormal Blood Pressures Systolic greater than 140*Diastolic greater than 90*Difference less than 30 between the Systolic and Diastolic Pressures.*140/90210/120 severe hypertensionThese are general guidelines and may differ from the guidelines that the provider you are employed by uses.
24Documenting a Blood Pressure Blood Pressures are Documented asSystolic / Diastolic12080
25Taking a PulseUsing your index and middle fingers, apply gentle pressure at the Radial Artery.Count the beats for 30 seconds and multiply by 2.
