SVI - norma:

A

33 - 47 ml/beat/m2

23
Q

SVRI - norma:

A

1970 - 2390

= 80 x (MAP - RAP) / CI

24
Q

PVRI - norma:

A

255 - 285

= 80 x (MPAP - PAOP) / CI

25
Q

Afterload is defined as:

A

Wall tension required to eject the SV during systole

26
Q

LaPlace law:

A

T = (P x r)/2

27
Q

Anrep effect:

A

Acute increase in afterload =>

reduction in SV =>

increase in EDV => restore of SV

28
Q

Is PAOP good for detection of fluid-responsiveness?

A

NO

but is good as a safety limit for oedema formation in lungs

29
Q

When can be dynamic indicators of preload used?

A

controlled UPV with no spont.activity
Vt > 8ml/kg

Contraindications: arrhythmias, severe tricuspid regurgitation

30
Q

PLR test is positive if:

A

SV is higher 10 - 20% in 60 - 90s

31
Q

Dodavka O2 (DO2I) - norma:

A

500 - 600 ml/min/m2

= CaO2 x CI x 10

32
Q

Spotreba O2 (VO2I) - norma:

A

120 - 160 ml/min/m2

= C(a - v)O2 x CI x 10

33
Q

O2ER - norma:

A

22 - 30%

= VO2/DO2 = (CaO2 - CvO2)/CaO2 x 100

= (SaO2 - SvO2)/SaO2

34
Q

SvO2 - norma:

A

65 - 75%

plne promichana venozni krev

bere se z PAC

A

20 ml/kg

39
Q

Rozdil mezi ventricular dysfunction x failure :

A

V dysfunction = SV ok, EF low

V failure = SV low, EF low

40

42
Q

Pulse pressure is defined:

A

SBP - DBP

43
Q

MAP is defined:

A
  • time-weighted average of arterial pressures

= (SBP + 2xDAP )/3

44
Q

Pressure waveform is peripherally:

A

distorted by wave reflections => higher SBP, pulse pressure

CAVE: vascular disease, vasodilatation drugs, vascular resistance
