➔ Pull the Snap Tab™ of the flush device and release immediately. ➔ Observe the pressure signal on the patient monitor. ➔ Compare the wave form with the figures to determine the dynamic response. If necessary repeat to verify maximum dynamic response.
CAUTION: An over- or under dampened wave may be the result of one or more of the following: - 3 way stopcock partially closed pressure line kinked or squeezed - Air in the pressure tubing and/or in the catheter - Loose connections in the system - Blood clots in catheter or in the pressure tubing - Catheter tip touching the vessel wall - Lumen too narrow - Use of foreign or addition pressure tubing or material

Advanced Thermodilution Curve Analysis
MTt: Mean Transit time -̂- time when half of the indicator has passed the point of detection in the artery
➔ For correct calculation of CO, only a fraction of the total injected indicator needs to pass the detection site. Simplified, only the change of temperature over time is relevant. ➔ The algorithm is capable of computing each single stroke volume (SV) after being calibrated by an initial transpulmonary thermodilution. ➔ After calibration, the pulse contour algorithm is able to follow the cardiac output Beat by Beat.

Press when performing further thermodilution measurements. Recalibrate 8 hourly or more frequently if patient condition unstable, if one measurement does not closely correspond to others, delete and re-perform.
➔ After central venous injection of the indicator, the thermistor at the tip of the arterial catheter measures the downstream temperature changes. ➔ Cardiac output is calculated by analysis of the thermodilution curve using a modified Stewart-Hamilton algorithm:

CALIBRATION
➔ The intrathoracic compartments can be considered as a series of “mixing chambers” for the distribution of the injected indicator (intrathoracic thermal volume).
PULSIOCATH
➔ The largest mixing chamber in this series are the lungs, here the indicator (cold) has its largest distribution volume (largest thermal volume). Patient-specific calibration factor (determined by thermodilution)

➔ ITBV and GEDV have been shown to be far more sensitive and specific to Cardiac Preload than the standard cardiac filling pressures CVP plus PCWP, and also right ventricular enddiastolic volume.
ITTV = CO * MTt
ITBV = 1.25 * GEDV
PTV = CO * DSt
GEDV = ITTV - PTV
➔ The striking advantage of ITBV and GEDV is that they are not adversely influenced by mechanical ventilation and give correct information regarding the preload status under any condition. ➔ Global End-Diastolic Volume (GEDV) is the volume of blood contained in the 4 chambers of the heart.
EVLW* = ITTV - ITBV
Troubleshooting: If the device shows an error message (E), please confirm with and check the system for correct setup and settings. Do a further Thermodilution Measurement. For detailed trouble shooting please refer to the PiCCO plus Operator’s Manual or contact your PULSION representative. In the case where you observe any product defect on disposables or accessories, please keep the product to be handed to your PULSION representative for further investigation.

➔ Extravascular Lung Water (EVLW)* is the amount of water content in the lungs. It allows bedside quantification of the degree of pulmonary edema.
➔ EVLW* has shown to have a clear correlation to severity of ARDS, length of ventilation days, ICU-Stay and Mortality and to be superior to assessment of lung edema by chest x-ray and CT scan.
Injectate temperature problem - Injection not detected - Injectate temperature sensor error
Possible cause - No signal transfer - Blocked sensor housing
Suggested remedy - Change injectate temp. sensor cable or housing - Change sensor housing
Thermodilution signal problem - TD curve does not appear - No TB (Blood Temperature) - TB incorrect
Possible cause - Defective catheter / cable - Defective catheter / cable - Catheter / calibration of system defective
Suggested remedy - Remove catheter / cable - Remove catheter / cable - Change cath. / call PULSION representative
Arterial blood pressure problem - Arterial pressure dampened - Arterial line flat or absent

➔ SVV reflects the sensitivity of the heart to the cyclic changes in cardiac preload induced by mechanical ventilation. ➔ SVV can predict whether stroke volume will increase with volume expansion ➔ SVV is only applicable in fully ventilated patients with regular heart rhythm
➔ EVLW* assessed by transpulmonary thermodilution has been validated against dye dilution and the reference gravimetric method.
➔ Intrathoracic Blood Volume (ITBV) is the volume of the 4 chambers of the heart plus the blood volume in the pulmonary vessels.
Interpretation Technically good measurement Error in determination of Tinj. Injection error Inject faster than 10 s Error in calculation of thermodilution curve parameters Time out (Thermodilution curve longer than 90s) Blood temperature lower than injectate temperature Invalid PCCO calibration
➔ Stroke Volume Variation (SVV) represents the variation of stroke volume (SV) over the ventilatory cycle.

Indications: Patients in whom cardiovascular and circulatory volume status monitoring are necessary. This includes patients in surgical, medical, cardiac and burn specialty units, as well as other specialty units where cardiovascular monitoring is desired, and patients undergoing major surgical interventions where cardiovascular monitoring is necessary. In short, every patient who requires a central venous and arterial catheter for monitoring. Contraindications: Patients in whom there are arterial access restrictions, for example due to femoral artery grafting or severe burns in areas where the arterial catheter would normally be placed. Note: The Axillary or Brachial artery can be used as an alternative site. Additionally a long radial artery catheter can also be placed for short term use. The PiCCO-Technology may give incorrect thermodilution measurements in patients with intracardiac shunts, aortic aneurysm, aortic stenosis, mitral or tricuspid insufficiency, pneumonectomy, macro lung embolism and extracorporeal circulation (if blood is either extracted from or infused back into the cardiopulmonary circulation). As is the case with all arterial catheters adequate perfusion downstream of the puncture site has to be assured. Adequacy of perfusion can be monitored using clinical inspection, surface temperature measurement, or by applying a pulse oximetry sensor to a digit downstream from the puncture site to continuously establish pulsatile flow.
Possible cause - Air in arterial line - Additional /foreign pressure line - Catheter kinked - Catheter clotted - No pressure in flush device - Defective cable - Defective pressure transducer - Calibration of system defective
Suggested remedy - Remove air from pressure line - Remove additional / foreign line - Avoid bending of catheter - Secure continuous flushing - Add pressure to flush device - Replace cable - Replace pressure transducer - Call PULSION representative

The catheters are also available as complete kits (e.g. PVPK2015L20-46), including a disposable pressure transducer and the injectate temperature sensor housing. Optionally, these kits can be ordered with an additional pressure line for intermittent central venous pressure monitoring. Catheters should be selected depending on patient size, weight and insertion site.
