A General Information
1 Intended Use
The PULSION PiCCO
2
´s intended use is the minimally invasi ve determination and monitoring of
cardiopulmonary and circulatory variables. Alon g with other bedside monitors and the clinical e valuation, the
PiCCO
2
detects the patient´s status and evaluates the need for and the suitability of treatment methods for the
care of critically ill patients in intensive care un its as well as for perioperative monitoring. If a patient´s correct
weight and height are entered, the PiCCO
2
presents the derived parameters indexed to the patient´s body
characteristics.
The PiCCO
2
uses up to four technologies:
1. Transpulmonar y thermodilution measurement for discontin uous determination of cardiac output and intra-
and extravascular fluid volumes.
2. Arterial pu lse contour analysis for the continuous det erminati on of cardiac output, volume responsiveness
and other derived parameters.
3. Fiberopt ic reflective measurement for the determination of oxygen saturation in the blood.
4. Pulse o ximetry for continuous monitoring of the functional oxygen saturation of arterial haemoglobin
(SpO
2
) and pulse densitometry for the determination of the concentra tion of Indocyanine Green, a dye
approved as a diagnostic drug.
The transpulmonary thermodilution technique and the arterial pulse contour analysis are not classified a s
measuring functions as stated in the Council Direct ive 93/42/EEC.
The PiCCO
2
is intended for use in hospitals and hospita l-like facilities and by trained health care
professionals.
The PiCCO
2
can be used in environments stated in the IEC 60601-1-1 Standard.
2 Indications
The use of the PiCCO
2
is indicated in patients where cardiovascular and circulatory volume status monitoring
is necessary. This includes patients underg oing surgical interventions of such magnitud e that cardiovascular
monitoring is necessary.
Continuous monitoring of central venous oxygen sa turation is indicated in all intensive care patient s
particularly in the case of sepsis and multi-organ fail ure; management of early goal directed therapy in severe
sepsis; for intra-operative monitoring of high ris k surgical patients and in emergency med icine and acute-care

repair the PiCCO
2
.
When the PiCCO
2
is connected to a bedside monitor, perfor m a zero adjustment of the PiCCO
2
before
zeroing the bedside monitor.
Medical:
If the zero adjustment is not performed, the bl ood pressure values may be wrong. Zero ad justment of the
pressure transducer is mandatory.
When restoring the calibration in the PCCO and ScvO
2
calibration menu an old calibration factor m ay be
used. Ensure that the values are plausible after having used this option.
If the displayed pulse contour parameters are not plausible, they should be checked b y a thermodilution
measurement. The pulse contour cardiac output measurement will be recalibrated automaticall y.
As the pulse contour cardiac output of children ha s not been sufficiently validated so far the CO should be
checked by thermodilution before therapeutic inter ventions.

Version 3.1
Recalibration is recommended with signifi cant changes in haemodynamic conditions, such as volume
shifts or changes to medication.
If the option of the continuous CVP measurem ent is not used, CVP should be updated as soon as a new
value is obtained to accurately calculate SVR and PCCO.
Faulty measurements can be caused by incorrectly placed catheters, interfering signal transmission e.g. of
arterial pressure, defective connections or sen sors or by electromagnetic interference (e.g. electric
blankets, electric coagulation).
Due to an aortic aneurysm the displayed bloo d volume (GEDV/ITBV) derived by a thermo dilution
measurement can be erroneously high.

B Principles of Measurement and Parameters
1 Introduction
The PiCCO
2
is a device for continuous cardiac output meas urement combined with monitoring of cardiac
preload volume, extravascular lung water, arterial and centr al venous oxygen saturation and global liver
function.
The PULSION PiCCO
2
computes the CO continuously, utilizing an improv ed arterial pulse contour analysis
algorithm. The Pulse Contour Cardiac Output (PCCO) is calibrated by means of a transpulmonary
thermodilution measurement. A cold or room-temperate bol us (e.g. normal saline 0.9%) is injected throu gh a
central venous catheter. A thermodilution curv e is recorded by an arterial thermodilution c atheter, which also
serves for pressure monitoring. In addition to ca libration of the PCCO, transpulmonary ther modilution also
yields cardiac preload by means of global end-diastolic vol ume (GEDV) and an estimation of both,
intrathoracic blood volume (ITBV) and extra vascular lung water (EVLW).
Furthermore the PiCCO
2
continuously measures the central venou s oxygen saturation (ScvO
2
) after
calibration with blood gas analysis results a nd can continuously calculate oxygen deli very (DO
2
) and oxygen
consumption (VO
2
).
Detection of concentration and determination of the eli mination rate of a diagnostic drug, Indocyanine Green,
provide information about the global liver function. The device indicates the Plasma Disappearance Rat e
(PDR) and the Retention Rate of ICG after 15 minutes (R15).
To derive parameters, the PiCCO
2
combines transpulmonary thermodilution technique w ith continuous arterial
pulse contour analysis and fiberoptic oximetry and pulse oximetry/densitometry. Oximetry measurements use
different wave lengths for the determination of the elimination rate of Indocyanine Green.
If a patient´s weight, height, category and gen der are entered, the PiCCO
2
presents the derived parameters
indexed to the patient´s body characteristic s.

Version 3.1
2 Transpulmonary Thermodilution Techni que
2.1 Principle
To accomplish thermodilution determination a know n volume of a suitable indicator (at least 10°C bel ow blood
temperature) is injected intravenously as qui ckly as possible. The recorded downstream te mperature change
is dependent on the flow and the volume through wh ich the cold indicator has passed. As a result, a
thermodilution curve can be recorded. The PiCCO
2
detects the cold indicator in the arterial system (preferably
in the femoral artery).
Figure 1: Heart-lung circulation and resulting ther modilution curve
2.2 Transpulmonary Cardiac Output
Cardiac Output (CO) is the volume of blood being pum ped by the heart in one minute.
Cardiac output by thermodilution is calculated according to t he Stewart-Hamilton formula (see Appendix)
using the area under the thermodilution curve.

2.3 Transpulmonary volume determination
Specific volumes can be calculated by multip lying cardiac output with characteristic time variables of the
thermodilution curve.
The parameters can alternatively be displayed a s absolute parameters or indexed to the patient´s body
characteristics.
The PiCCO

GEDV ITBV
Figure 2: GEDV / ITBV
Global End-Diastolic Volume (GEDV) is the total amount of blood left in all four heart chambers, i. e. atria and
ventricles, at the end of diastole.
Intrathoracic Blood Volume (ITBV) represents the t otal amount of blood in the thorax.
GEDV and ITBV reflect the circulatory volume stat us and are excellent indicators of cardia c preload. GEDV
and ITBV are used for managing the patient´s va scular filling status and guiding volume therapy.
CAUTION: Aortic aneurysms may cause the d isplayed blood volume (GEDV/ITBV) derived by
thermodilution measurement to be erroneously high.

2.3.2 EVLW
EVLW quantifies the extravascular fluid volu me in the lungs. It is used to alert the clin ician to the existence or
development of pulmonary edema. When measuring lun g water the intra-alveolar, intracellular and inter stitial
lung water are considered. However, a pleural effusion d oes not influence measurements.

2.3.3 Additional Thermodilution Parameters
2.3.3.1 GEF:
GEF mainly depends on right and left ventricular co ntractility and can be used to detect right and/or left
ventricular dysfunction. GEF is derived from the rat io of four stroke volumes divided by Global End-
Diastolic Volume (GEDV).
Figure 4: Global Ejection Fraction (GEF)
2.3.3.2 CFI:
CFI represents the ratio between cardiac output a nd global end-diastolic volume (GEDV).
2.3.3.3 PVPI
PVPI shows the relationship between EVLW and PBV (Pulm onary Blood Volume) and can help to
distinguish between hydrostatic and permeabilit y caused pulmonary edema.

3 Continuous Pulse Contour Analysis
3.1 Principle
The relationship between blood flow out of the a orta and pressure measured near the aorta (femoral arter y or
other large artery) is determined by the compliance function. The compliance function can therefore be
characterized by measuring blood pressure and bl ood flow (cardiac output) simultaneously . Transpulmonary
thermodilution cardiac output determined simultaneo usly with continuous arterial pressure measurement is
utilized to calibrate the pulse contour analysis to each individual patient´s aortic complianc e function.
3.2 Calibration of the Pulse Contour Cardiac Output
To calibrate the measurement of continuous cardiac outpu t, a reference thermodilution cardiac output is
necessary. The PiCCO
2
uses the transpulmonary thermodilut ion as reference method.

Moreover, central venous pressure (CVP) in m mHg can be measured continuously.
3.3.1 MAP / CVP / HR
MAP (Mean Arterial Pressure)
Mean arterial pressure is the mean value of the blood pressure in the arterial system.
CVP (Central Venous Pressure)
Central venous pressure is the average blood pressure directly before the right heart.
HR (Heart Rate)
Heart rate is the number of heart beats per minute.
3.3.2 PCCO
Pulse contour cardiac output is the continuously determ ined cardiac output from the pulse contour analysis.
CAUTION: As the pulse contour cardiac output of children has not been sufficiently validated thus
far, the CO should be checked by thermodilution befor e therapeutic interventions.
Recalibration is recommended with signifi cant changes in haemodynamic conditions, such as
volume shifts or changes to medication.

Figure 7: PPV
In mechanically ventilated patients without arrh ythmias SVV and PPV enable an estimation of the volume
responsiveness. Large variations in stroke volume or pulse pressure induced by mechanical vent ilation
indicate that volume loading will lead to an increas e in cardiac ejection (volume responsiv eness).
3.3.4 SVR
SVR represents the resistance the blood encounter s as it flows through the vascular syste m. The SVR value
is often used by clinicians as an estimate of afterload.
3.3.5 CPO
The CPO is the product of cardiac output and mean arter ial pressure, thus reflecting the cardiovascular blood
flow related to the counteractive resistance. CPO serve s as an indicator for the overall performance of the
heart.
3.3.6 dPmx
dPmx is the abbreviation for ΔP
max
/Δt. This parameter indicates how fast the aortic pres sure is rising during
systole. It allows a close approximation of the contractility of the left ventricle. In additio n to CFI/GEF, dPmx
can be used to manage the administration of posit ive inotropic and cardiovascular agents.

4 Central venous oximetry
4.1 Principle
The PiCCO
2
measures central venous oxygen saturation (S cvO
2
) by spectrophotometry. Spectrophotometry
involves the use of light emitting diodes (LED) that produ ce light of various wavelengths in red and infrared
spectra. The light is transmitted to the blood through a fiberoptic in the probe, reflected off the red bl ood cells
and transmitted back through a separate fiberoptic to a n optical module.
Figure 9: The principle of spectrophotometry
The wavelengths are selected in a way that the abs orption characteristics of haemoglobin and
oxyhaemoglobin are different. Given both the a mount of total haemoglobin and the amount of haemoglob in
bound to oxygen, oxygen saturation can be cal culated.
4.2 Determination of ScvO
2
ScvO
2
reflects the oxygen saturation of the haemoglobin in th e blood in the superior vena cava directly bef ore
the right atrium. It is an early indicator of an imb alance between oxygen delivery and oxygen consumption.
Thus this parameter early indicates a threat to global tissue oxygenation.

5 Pulse oximetry and pulse dye densitometry
5.1 Principle of pulse oximetry
Pulse oximetry measures the percentage oxygen satur ation of the haemoglobin. The principle of pulse
oximetry is based on the transmission and absorption of light waves in the visible and near-infrared spectrum
by haemoglobin. Light of different wavelengths is sent through the tissue non-invasively and is subsequently
detected by a sensor. The received light signal is used to determine the oxygen saturation. This measuremen t
is entirely non-invasive.
Pulse oximetry is used to measure the partial ox ygen saturation of haemoglobin i.e. only oxygenated and
deoxygenated haemoglobin is included. However, not included is e.g. carboxyhaemoglobin or
methaemoglobin.
WARNING: External influences: carboxyhaemoglob in can result in incorrect high values for SpO
2
.
The degree of elevation is approximately equal to the amo unt of carboxyhaemoglobin present.
Dye (e.g. Indocyanine Green) or other substance s which contain dyes which usually modify the
light absorption capacities, can lead to faulty m easurement values of the oxygen saturatio n.
WARNING: The measurement of SpO
2
is not recommended for patients weighing less tha n
20 kg (44lbs).
5.2 Principle of pulse dye densitometry
The principle of pulse dye densitometry and with it, the measurement of th e plasma disappearance rate of
Indocyan ine Green (ICG) is based on pulse oximetry. The difference is that other light wavelengths are u sed
than with pulse oximetry.

Version 3.1
5.3 Principle of ICG elimination detection
ICG has an absorption maximum of approximately 805 nm. The determination of ICG concentration within thi s
range (optical window) is not disturbed by other b lood components.
The trend in ICG concentration over time is u sed to calculate the relative change in perce nt per minute. The
plasma disappearance rate (PDR) of ICG is a measure of the excretory capacity of the liver and thus glo bal
liver function. It is influenced by the function of liver cells as well as the liver perfusion. Depending on th e
patients underlying disease the PDR helps to ass ess the patient´s liver function and/or liver perfusion. As the
liver is part of the splanchnic area, splanch nic perfusion can be indirectly estimated.
Figure 11 : Schematic representation of the ICG el imination curve
The figure above shows a typical ICG concentrat ion curve with the initial peak and its cour se over
500 seconds. The elimination measurement start s after thorough mixing of ICG with the circulating blood
volume. The starting point of the PDR measurement is determined dynamically dependent on the circulation
time derived from the first peak. The ICG curve ana lysis continues for five to ten minutes, dependent on the
quality of the curve.
The starting point represents 100%. The algorithm d etects a percentage decrease per minute and indicates
the PDR in percent per minute.
NOTE
For information on the diagnostic drug, Indocyanine Green, please refer to the corresponding
SPC (summary of pro duct characteristics) or PIL (patient info rmation leaflet) of ICG.
