Version 3.1 A-1
AGeneral Information
1Intended Use
The PULSION PiCCO2´s intended use is the minimally invasive determination and monitoring of
cardiopulmonary and circulatory variables. Along with other bedside monitors and the clinical evaluation, the
PiCCO2 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 units as well as for perioperative monitoring. If a patient´s correct
weight and height are entered, the PiCCO2 presents the derived parameters indexed to the patient´s body
characteristics.
The PiCCO2 uses up to four technologies:
1. Transpulmonary thermodilution measurement for discontinuous determination of cardiac output and intra-
and extravascular fluid volumes.
2. Arterial pulse contour analysis for the continuous determination of cardiac output, volume responsiveness
and other derived parameters.
3. Fiberoptic reflective measurement for the determination of oxygen saturation in the blood.
4. Pulse oximetry for continuous monitoring of the functional oxygen saturation of arterial haemoglobin
(SpO2) and pulse densitometry for the determination of the concentration of Indocyanine Green, a dye
approved as a diagnostic drug.
The transpulmonary thermodilution technique and the arterial pulse contour analysis are not classified as
measuring functions as stated in the Council Directive 93/42/EEC.
The PiCCO2 is intended for use in hospitals and hospital-like facilities and by trained health care
professionals.
The PiCCO2 can be used in environments stated in the IEC 60601-1-1 Standard.
2Indications
The use of the PiCCO2 is indicated in patients where cardiovascular and circulatory volume status monitoring
is necessary. This includes patients undergoing surgical interventions of such magnitude that cardiovascular
monitoring is necessary.
Continuous monitoring of central venous oxygen saturation is indicated in all intensive care patients
particularly in the case of sepsis and multi-organ failure; management of early goal directed therapy in severe
sepsis; for intra-operative monitoring of high risk surgical patients and in emergency medicine and acute-care
for fast track evaluation of the patient´s haemodynamic condition.
The Indocyanine Green concentration and elimination measurement is indicated in all patients with persistent
or expected limitations of the global liver function (cellular function or perfusion).

General Information
Page A-2 Operator’s Manual PiCCO2
Version 3.1
3Contraindications
The invasive technologies in the PiCCO2 should not be used in patients where the placement of an indwelling
arterial catheter or a central venous catheter is contraindicated. The PiCCO2 should only be used in patients
where the expected results are reasonable in comparison to the risks. Patients on intra-aortic balloon counter
pulsation (IABP) cannot be monitored with the pulse contour analysis of the device. Transpulmonary
thermodilution however works during IABP support.
WARNING: Federal (USA) law restricts this device for sale by or on the order of a physician.
The device is intended for use in hospitals and hospital-like facilities by trained and informed health
care professionals.
For contraindications of the diagnostic drug, Indocyanine Green, please refer to the corresponding SPC
(summary of product characteristics).

Position the equipment in such a manner that neither the device nor other equipment attached to the
device can fall on the patient. Never lift or carry the device by the mains supply cable or the cable attached
to the patient.
When using the provided assembly facilities pay attention to a correct installation. The used system must
be sufficiently stable and tilt resistant as well as medically approved. In order to ensure a secure
connection with the mounting system the locking mechanism of the universal adapter plate must be
completely snapped in place.
Place the cables attached to the patient carefully so that the patient is not in danger of becoming
entangled or strangulating him/herself with the cables.
Medical:
The device enables the monitoring of physiological parameters. The clinical significance of changes in the
monitored parameters must be determined by a physician.
If a new patient is connected to the device without the device being shut down, the procedure "New
Patient" must be selected. Otherwise data from the last patient is still displayed.
The PiCCO2 may only be regarded as a device providing early warning. If there is an indication of a trend
towards de-oxygenation of the patient, blood samples must be taken and tested on a laboratory oximeter
in order to arrive at a decision concerning the condition of the patient.
The device must not be used for monitoring breathing.
The device must not be used for monitoring heart rate, arterial blood pressure and body temperature.
Before using the device the setting of the alarm limits and the alarm volume must be checked regarding
their suitability for the respective patient.

General Information
Page A-4 Operator’s Manual PiCCO2
Version 3.1
If an alarm condition arises while the alarm is suppressed, only the optical warning will be given.
During the start up procedure an acoustic sound appears at the end of the activation time. If this sound
does not appear no acoustic alarm can take place.
External influences: carboxyhaemoglobin can result in incorrect high values for SpO2. The degree of
elevation is approximately equal to the amount of carboxyhaemoglobin present. Dye (e.g. Indocyanine
Green) or other substances which contain dyes which usually modify the light absorption capacities, can
lead to faulty measurement values of the oxygen saturation.
The measurement of SpO2 is not recommended for patients weighing less than 20 kg (44lbs).
Do not use the device while a NMR scan is being carried out. An induced voltage can result in potential
burns.
Disposables:
When placing the arterial catheter into a large artery (e.g. femoral, brachial or axillary artery) do not
advance the tip of the catheter into the aorta.
An intracardiac blood pressure measurement is not allowed. This means that the measuring position
(i.e.catheter tip) must not be in the heart.
Further use of disposable items is not allowed. Re-sterilization of disposables may cause infections in the
patient.
Incorrect use of the ScvO2 probe can lead to vessel perforation. Therefore check the correct position of the
probe as indicated in the probe´s instructions for use.
Electrical:
Do not use damaged probes or patient cables. Do not use any probes with exposed optical or electrical
components.
Do not reconnect the PiCCO2 to electrical power if liquid has entered the device. A short circuit may
damage the device and cause hazardous conditions for patient and user.
Remove patient cables which are not needed. The used components are not galvanically isolated from
each other.
The PiCCO2 always has to be connected with the protective earth conductor. Never use mains supply
cable or extension lines without protective earth conductor.
Connect the potential equalization at the back of the device with the potential equalization system of the
treatment room.

5Safety instructions
CAUTION
General:
Do not expose the PiCCO2 to temperatures above 40 °C (104 °F) or below 10 °C (50 °F). The accuracy of
the measured values may be affected.
Do not pull on the probes or cables in order to remove them from the device. Observe the instructions for
use for the probes in order to ensure that a technically correct procedure is carried out.
Do not place other equipment or containers with liquid on top of the PiCCO2.
Never place the cables in water or other cleaning solutions. The cables and connections are not water-
tight. Never sterilize the cables by radiation, steam or gas.
Do not use abrasive or sharp-edged tools to clean the optical module as this may damage or destroy
optical components.
If the device is not standing on a slip-proof surface and to prevent displacement, hold the unit securely
while the function keys are being pressed.
Preparations for Use:
The user must assure him-/herself of the safe and fully functional condition of the equipment before using
it.
If the PiCCO2 appears to be damaged, contact your local PULSION representative. Do not use the PiCCO2
if the device appears to be damaged.
If the system check detects a failure, no function will be available and “SERVICE” is displayed on the
screen. Turn the PiCCO2 off and contact your local PULSION representative. Do not attempt to use or
repair the PiCCO2.
When the PiCCO2 is connected to a bedside monitor, perform a zero adjustment of the PiCCO2 before
zeroing the bedside monitor.
Medical:
If the zero adjustment is not performed, the blood pressure values may be wrong. Zero adjustment of the
pressure transducer is mandatory.
When restoring the calibration in the PCCO and ScvO2 calibration menu an old calibration factor may 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 by a thermodilution
measurement. The pulse contour cardiac output measurement will be recalibrated automatically.
As the pulse contour cardiac output of children has not been sufficiently validated so far the CO should be
checked by thermodilution before therapeutic interventions.

General Information
Page A-6 Operator’s Manual PiCCO2
Version 3.1
Recalibration is recommended with significant changes in haemodynamic conditions, such as volume
shifts or changes to medication.
If the option of the continuous CVP measurement 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 sensors or by electromagnetic interference (e.g. electric
blankets, electric coagulation).
Due to an aortic aneurysm the displayed blood volume (GEDV/ITBV) derived by a thermodilution
measurement can be erroneously high.
Electrical:
The PiCCO2 is subject to specific precautions concerning EMC (Electromagnetic compatibility) and is only
allowed to be installed and used according the EMC advice contained in this user´s manual. Portable and
mobile high frequency communication devices may influence the PiCCO2.
Any additional item of equipment which is connected to the digital interface must satisfy the EMC
requirements of the IEC specification 60601-1-2.
Furthermore, all configurations have to meet the system standard IEC 60601-1-1. Any person who
connects additional devices to the signal input or signal output of the PiCCO2 is changing the system
configuration and is responsible for observing the requirements of the IEC 60601-1-1 standard.
When high frequency devices are used during surgery, the applying standards for high frequency devices
for surgery have to be followed.
Check the battery state of charge when using the device. Only when the battery is fully charged, the
use of the device can be ensured for the stated time without being connected to the mains.
If the connection to the protective earth conductor cannot be ensured, separate the device from the mains
supply and only use the device on battery power.

Principles of Measurement and Parameters

Version 3.1 B-1
BPrinciples of Measurement and Parameters
1Introduction
The PiCCO2 is a device for continuous cardiac output measurement combined with monitoring of cardiac
preload volume, extravascular lung water, arterial and central venous oxygen saturation and global liver
function.
The PULSION PiCCO2 computes the CO continuously, utilizing an improved 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 bolus (e.g. normal saline 0.9%) is injected through a
central venous catheter. A thermodilution curve is recorded by an arterial thermodilution catheter, which also
serves for pressure monitoring. In addition to calibration of the PCCO, transpulmonary thermodilution also
yields cardiac preload by means of global end-diastolic volume (GEDV) and an estimation of both,
intrathoracic blood volume (ITBV) and extravascular lung water (EVLW).
Furthermore the PiCCO2 continuously measures the central venous oxygen saturation (ScvO2) after
calibration with blood gas analysis results and can continuously calculate oxygen delivery (DO2) and oxygen
consumption (VO2).
Detection of concentration and determination of the elimination rate of a diagnostic drug, Indocyanine Green,
provide information about the global liver function. The device indicates the Plasma Disappearance Rate
(PDR) and the Retention Rate of ICG after 15 minutes (R15).
To derive parameters, the PiCCO2 combines transpulmonary thermodilution technique with 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 gender are entered, the PiCCO2 presents the derived parameters
indexed to the patient´s body characteristics.

Principles of Measurement and Parameters

Version 3.1
2Transpulmonary Thermodilution Technique
2.1 Principle
To accomplish thermodilution determination a known volume of a suitable indicator (at least 10°C below blood
temperature) is injected intravenously as quickly as possible. The recorded downstream temperature change
is dependent on the flow and the volume through which the cold indicator has passed. As a result, a
thermodilution curve can be recorded. The PiCCO2 detects the cold indicator in the arterial system (preferably
in the femoral artery).
Figure 1: Heart-lung circulation and resulting thermodilution curve
2.2 Transpulmonary Cardiac Output
Cardiac Output (CO) is the volume of blood being pumped by the heart in one minute.
Cardiac output by thermodilution is calculated according to the Stewart-Hamilton formula (see Appendix)
using the area under the thermodilution curve.

Version 3.1 B-3
2.3 Transpulmonary volume determination
Specific volumes can be calculated by multiplying cardiac output with characteristic time variables of the
thermodilution curve.
The parameters can alternatively be displayed as absolute parameters or indexed to the patient´s body
characteristics.
The PiCCO2 uses predicted body weight (PBW) to index intrathoracic volumetric parameters.

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 total amount of blood in the thorax.
GEDV and ITBV reflect the circulatory volume status and are excellent indicators of cardiac preload. GEDV
and ITBV are used for managing the patient´s vascular filling status and guiding volume therapy.
CAUTION: Aortic aneurysms may cause the displayed blood volume (GEDV/ITBV) derived by
thermodilution measurement to be erroneously high.

Version 3.1
2.3.2 EVLW
EVLW quantifies the extravascular fluid volume in the lungs. It is used to alert the clinician to the existence or
development of pulmonary edema. When measuring lung water the intra-alveolar, intracellular and interstitial
lung water are considered. However, a pleural effusion does not influence measurements.
Figure 3: Extravascular Lung Water (EVLW)
2.3.3 Additional Thermodilution Parameters
2.3.3.1 GEF:
GEF mainly depends on right and left ventricular contractility and can be used to detect right and/or left
ventricular dysfunction. GEF is derived from the ratio of four stroke volumes divided by Global End-
Diastolic Volume (GEDV).

2.3.3.2 CFI:
CFI represents the ratio between cardiac output and global end-diastolic volume (GEDV).
2.3.3.3 PVPI
PVPI shows the relationship between EVLW and PBV (Pulmonary Blood Volume) and can help to
distinguish between hydrostatic and permeability caused pulmonary edema.

3Continuous Pulse Contour Analysis
3.1 Principle
The relationship between blood flow out of the aorta and pressure measured near the aorta (femoral artery or
other large artery) is determined by the compliance function. The compliance function can therefore be
characterized by measuring blood pressure and blood flow (cardiac output) simultaneously. Transpulmonary
thermodilution cardiac output determined simultaneously with continuous arterial pressure measurement is
utilized to calibrate the pulse contour analysis to each individual patient´s aortic compliance function.
3.2 Calibration of the Pulse Contour Cardiac Output
To calibrate the measurement of continuous cardiac output, a reference thermodilution cardiac output is
necessary. The PiCCO2 uses the transpulmonary thermodilution as reference method.

3.3 Continuous haemodynamic determination
The following parameters are derived by the PULSION PiCCO2 , analyzing the arterial pressure curve beat by
beat. The parameters can alternatively be displayed as absolute parameters or indexed to the patient´s body
characteristics.

Moreover, central venous pressure (CVP) in mmHg 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 determined 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 before therapeutic interventions.
Recalibration is recommended with significant changes in haemodynamic conditions, such as
volume shifts or changes to medication.
