Insert a part of the guidewire through the cannula into the artery.  Leave the guidewire in place and withdraw the cannula.  Enlarge the point of entry by performing a skin incision using a scalpel.  With a twisting motion, advance the dilator over the guidewire into the vessel.  Leave the guidewire in place and withdraw the dilator.  With a twisting motion, insert the catheter over the guidewire into the vessel.  Hold catheter at the desired position and withdraw guidewire.

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.

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)  Pulse Contour Analysis  Heart rate  Area under pressure curve  Aortic compliance  Shape of pressure curve  ➔ 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.

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  PULSION Benelux nv/sa +32-9-242 99 10 info@pulsion.be  ☎  ➔ 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.

Ltd., AUS +61-7-32 66 84 48 info@pulsionpacific.com.au  ☎  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  PULSION and PiCCO are registered tradenames of PULSION Medical Systems AG Munich.
