Hemodynamics

Question 1

MAP

Answer 1

MAP = [(2 x Diastolic) + Systolic] / 3

Question 2

Pulse Pressure Variation (PPV)

Answer 2

PPV = (PPmax - PPmin) / [(PPmax + PPmin) / 2] * 100 (%)

الفرق بينهما على متوسط قيمتهما

Question 3

Systemic Vascular Resistance (SVR)

Answer 3

SVR = [(MAP - Central Venous Pressure) / CO] x 80 (Dynes.sec/cm^5)

MCQs

Question 4

Shock Index

Answer 4

Shock Index = Heart Rate / Systolic Blood Pressure

Normal 0.5 to 0.7
> 0.7 shock?

Question 5

Cardiac Index (CI)

Answer 5

CI = CO / Body Surface Area (BSA) (L/min/m²)

Question 6

Cardiac Output (CO)

Answer 6

CO = Stroke Volume (SV) x Heart Rate (HR) (L/min)

MCQs

Question 7

Stroke Volume Index (SVI)

Answer 7

SVI = SV / Body Surface Area (BSA) (ml/m²)
