Q

Oxygen Delivery (DO2) Formula

A

Co x [(Hgb x SaO2 x 1.340 + ( PaO2 x 0.003)] x 10

10 is a conversion factor that fixes g/dL of Hgb & L/ min of CO

2
Q

How much O2 is carried in arterial blood?

A

Oxygen Carrying capacity: CaO2

20 mL/ dL

3
Q

How much O2 is being delivered to tissues?

A

Oxygen Delivery: DO2

1000 mL/ min

4
Q

How much O2 is extracted by the tissues?

A

Oxygen Extraction Ratio: EO2

25% (reference for the whole body)

5
Q

How much O2 is consumed by the tissues?

A

Oxygen Consumption: VO2

250 mL/ min

6
Q

How much O2 is carried in the venous blood?

A

Venous Oxygen Content: CvO2

15 mL/ dL

7
Q

Cardiac output Formula… and normal value?

A

HR x SV

Normal Value: 5-6 L/min

8
Q

Cardiac Index Formula… and normal value

A

CO/ BSA

Normal value 2.8 to 4.2 L/min/m^2

9
Q

Stroke Volumen Formula… and normal value

A

EDV - ESV
50 to 110 mL/ beat

OR

CO x 1000/HR

10
Q

Stroke Volume index Formula and normal value

A

SV/ BSA

35 to 65 mL/beat/ m^2

11
Q

Ejection Fraction Formula… and normal value

A

[(EDV- ESV) / EDV] x 100

60 to 70%

12
Q

Mean Arterial Blood Pressure Formulas… and normal value

A

(1/3 x SBP) + (2/3 x DBP)

[(CO x SVR) / 80] + CVP

70- 105 mmHg

13
Q

Pulse Pressure Formula … and normal value?

A

SBP - DBP

40 mmHg

14
Q

Systemic Vascular Resistance formula and normal value?

A

[(MAP - CVP)/ CO] x 80

900-1400 dynes/ sec/ cm^-5

15
Q

Systemic Vascular Resistance index formula and normal value?

A

[(MAP - CVP)/ CI] x 80

1500 to 2400 dynes/sec/ cm^-5/m^2

16
Q

Pulmonary Vascular Resistance formula and normal value?

A

[(MPAP - PAOP) / CO] x 80

150 - 250 dynes/sec/ cm^-5

17
Q

Pulmonary Vascular Resistance index formula and normal value

A

[(MPAP - PAOP) / CI] x 80

250 - 400 dynes/ sec/ cm^-5/ m^2
