This chapter is relevant to Section G7(iv) of the 2017 CICM Primary Syllabus, which asks the exam candidate to "describe the methods of measurement of cardiac output including calibration,
sources of errors and limitations".
These are the equations used to arrive at the numbers which the machine spews out after you have done a thermodilution, as well as the normal ranges for those numbers.
To derive EVLW from measured variables:
CO: Cardiac Output
CI: Cardiac Index

ITTV: Intrathoracic Thermal Volume

PTV: Pulmonary Thermal Volume

GEDV: Global End-Diastolic Volume
GEDI: Global End-Diastolic Index
ITBV: IntraThoracic Blood Volume
ITBI: IntraThoracic Blood Volume Index
EVLW: Extravascular Lung Water
EVLWI: Extravascular Lung Water Index
CFI: Cardiac Function Index
GEF: Global Ejection Fraction
PVPI: Pulmonary Vascular Permeability Index
SV: Stroke volume
SVI: Stroke Volume Index
SVV: Stroke Volume Variation
dPmax: maximum left ventricular contractility
