New cards

SYSTOLIC PRESSURE

BLOOD PRESSURE DURING HEART CONTRACTION

2
New cards

DIASTOLIC PRESSURE

BLOOD PRESSURE DURING HEART RELAXATION

3
New cards

NORMAL VALUE BLOOD PRESSURE

120/80

4
New cards

HYPOTENSION VALUE

80/50

5
New cards

SHOCK VALUE

60/30

6
New cards

PREHYPERTENSION VALUE

120-139 / 80-89

7
New cards

STAGE I HYPERTENSION VALUE

140-159 / 90-99

8
New cards

STAGE II HYPERTENSION

160 OU + / 100 OU +

9
New cards

2 PHYSIOLOGICAL CAUSES OF HYPERTENSION

→ INCREASE OF CARDIAC OUTPUT

→ INCREASE OF VASCULAR RESISTANCE (VASOCONSTRICTION)

10
New cards

RAPPEL CARDIAC OUTPUT =

HR X SYSTOLIC VOLUME

11
New cards

PRIMARY HYPERTENSION → % ? CAUSE ?

95% DES CAS

→ IDIOPATHIC ORIGIN

12
New cards

IDIOPATHIC ORIGN DEF

= UNKNOWN ORIGIN

13
New cards

SECONDARY HYPERTENSION : % ? CAUSE ?

5%

→ CAUSED BY AN UNDERLYING DISEASE

14
New cards

3 MAINS TYPES OF DISEASES CAUSING SECONDARY HYPERTENSION ?

RENAL DISEASE / ENDOCRINE DISEASE / DRUGS

15
New cards

GENERAL SYMPTOM W/ HYPERTENSION ?

GENERALLY ASYMPTOMATIC

16
New cards

SYMPTOMS APPEARS WHEN ?

WHEN THERE IS DAMAGE TO TARGET ORGANS

17
New cards

4 MAIN TARGET ORGANS

HEART

BRAIN

RETINA

KIDNEY

18
New cards

RAPPEL HYPOTENSION VALUE

<80 / <50

19
New cards

2 MAINS PHYSIOLOGICAL CAUSES OF BP DECREASE ?

CARDIAC OUTPUT ↓ = LESS BLOOD PUMPED

VASCULAR RESISTANCE ↓ = VASODILATATION

20
New cards

LOW BP + NO SYMPTOMS →

ASYMPTOMATIC HYPOTENSION

21
New cards

LOW BP + WEAKNESS WHEN CHANGING POSITION ?

ORTHOSTATIC HYPOTENSION

22
New cards

LOW BP + SYNCOPE →

SYMPTOMATIC HYPOTENSION

23
New cards

4 MAIN SIGNS HYPOTENSION SHOCK

WEAK PULSE

TACHYCARDIA

COLD SKIN

ALTERED MENTAL STATE

( + HYPOTENSION)

24
New cards

3 MAIN TYPES OF SHOCK

CARDIOGENIC

HYPOVOLEMIC

DISTRIBUTIVE

25
New cards

CARDIOGENIC SHOCK DEF

PUMP FAILURE → HEART NOT ABLE TO SEND ENOUGH BLOOD TO THE ORGANS

26
New cards

VALEUR DE LVEF DANS CARDIOGENIC SHOCK

LVEF < 20 %

27
New cards

HYPOVOLEMIC SHOCK DEF

SEVERE DECREASE OF CIRCULATING BLOOD VOLUME

28
New cards

2 MAIN CAUSE OF BLOOD VOLUME DECREASE ?

HEMMORHAGE / SEVERE DIARRHEA

29
New cards

DISTRIBUTIVE SHOCK DEF

VASCULAR TONE FAILURE → SEVERE VASODILATATION

30
New cards

2 TYPES OF DISTRIBUTIVE SHOCK

→ SEPTIC SHOCK

→ ANAPHYLACTIC SHOCK

31
New cards

TRIGGER SEPTIC SHOCK

SEVERE INFECTION + VASODILATATION + HYPOPERFUSION

32
New cards

TRIGGER ANAPHYLACTIC SHOCK

SEVERE ALLERGIC REACTION + MEDIATOR RELEASE + VASODILATATION
