Q

V/Q

A

22
Q

Ventilatory response to PaCO2 and PaO2

A

.

23
Q

PVR

A

.

24
Q

CVP waveform

A 
a = atrial contraction
c = closure of tricuspid valve, ventricular contraction 
x = atrial relaxation 
v = atrial filling 
y = opening of tricuspid valve, ventricular filling

Systole is between start of c wave and end of v wave.

AF: loss of a waves
TR: loss of x descent, giant v waves
CHB: cannon a waves

CVP reflects the pressure in the great veins of the thorax, and hence the RA. It approximates RV preload. Highest at end expiration in SV and end inspiration in IPPV.

25
Q

Arterial waveform

A

Upstroke: contractility (slurred upstroke in AS)
Dicrotic notch: AV closure; low in low preload AUC up to dicrotic notch): SV
Downstroke: SVR
Swing: >10mmHg suggests underfilled
Pulse pressure: wide in AR, narrow in AS/tamponade/cardiogenic shock/massive PE/tension PTX)

26
Q

ICP waveform

A

Percussion
Tidal
Dichrotic

27
Q

Damping and resonance

28
Q

Wheatstone bridge

A

29
Q

Pulmonary artery catheter

A

RA - inflate balloon once waveform seen
RV
PA
PCWP 6-12mmHg (measured at end expiration) at 45-55cm

Investigation of shock aetiology, cardiac shunts, CO measurement, PHTN, route for cardiac pacing.

Info: SvO2, CO, core temp, PCWP = LVEDP estimate, RA/RV/PAP, CVP, SVR (derived).

Normal SvO2 70-75%; lower in low CO, increased O2 consumption, reduced O2 content.

34
Q

Flow volume loops

A

Restrictive
Obstructive
Fixed extrathoracic obstruction

NB flow volume loops are better than spirometry as effort/technique independent.

35
Q

Oesophageal Doppler trace

A

Flow time corrected = preload (normal = 330-360ms)
Peak velocity = contractility
AUC = stroke distance (can calculate SV)

42
Q

RAAS

A

Angiotensin II has 5 actions: vasoconstriction, thirst, and release of ADH, ACTH and aldosterone

43
Q

Catecholamine synthesis pathway

A

PLL DNA

44
Q

Spirogram (volume/time graph)

A

Normal, obstructive and restrictive

45
Q

Antibiotic classes

A 
Inhibit cell wall synthesis 
- beta lactams 
- glycopeptides 
Protein 
- 30s: aminoglycosides 
- 50s: macrolides 
DNA 
- Fluroquinolones
