Connection of the Filter. Which filter is chosen for therapy and why. Point out the direction of the blood flow and why this is important. Connection of the filtrate port to the upper side port on the filter. Why is the port placed here? Would it make a difference to connect the filtrate port to the lower side port on the filter? 3

4 SET UP (Continued) Connection of the predilution / Dialysate port. What is the significance / benefit of predilution? When would dialysate be used and why? Why does dialysate run countercurrent to the blood flow? Connection of the drainage bag to the Access line. Why is this bag connected to the Access line?

5 PRIMING Commence Priming. Prime the Aquarius circuit successfully according to company recommendations and unit policy. Priming commenced at 80ml/min. Why? How long does priming of the Aquarius circuit take. Priming at 150ml/min. Why? What do you do if part of the circuit fails to prime? CLAMP AND PRESSURE TEST Navigates to the Clamp and Pressure test post priming. Moves Access line to the same saline bag as return line. Perform Clamp and pressure test accurately and successfully. What is the clamp and pressure test trying to achieve. Successful completion of clamp and pressure test. 5

6 RECIRCULATION Navigate to Recirculation mode. Put the Aquarius machine into Recirculation Mode Commence recirculation successfully What is the purpose of recirculation? How long should you / could you re-circulate for. At what other times could you use recirculation? Explain how you would change bed spaces with the Aquarius. PROGRAMMING Are the medical orders complete and correct and reasonable? Programme Aquarius as per medical orders and commence therapy. Navigate to the programming screen. Programme Aquarius according to medical orders for the Blood flow rate Time Goal? Fluid loss and goal loss Predilution / dialysate rate and Post dilution rate Anticoagulant rate Temperature goal. Reset option discuss. 6

7 CONNECTION Connect patient to the Aquarius Haemofiltration machine Connect patient to the Aquarius using hospital procedure and protocol. Have you chosen a double or a single connection and why? What are the pros and cons of both? Have all equipment to connect to patient Does the vascath flush well? If not, potentially why not and what could be done to overcome this? Commence filling circuit with blood. Remain with the patient after pressing the blood pump key to start. What is the default speed for the blood pump during connection? In single connection, when does the clamp come on? Commence therapy Monitor the patients haemodynamic response to commencement of therapy Observe access site and all connections Chart initial pressures Explain the anticoagulation protocol Explain why anticoagulation is used Identify when blood samples are taken to check anticoagulation levels State what target APTT range is 7

8 OPERATION Explain potential indications and complications related to Identify and explain the potential complications of CRRT. Infection Fluid imbalances Electrolyte imbalances Bleeding Heparinisation Circuit clotting Filter clogging Fractured filter fibres Accidental disconnection / removal / dislodging of vascath Spontaneous hypotension Bradycardia Cardiac Arrest OPTIMISATION OF THERAPY Navigate to the more screen Discuss the Prefilter pressure and its relevance to your circuit. Discuss the UF variation and its relation to the balance system What is the meaning of the Filtration Ratio Discuss the Filtrate Pressure 8

9 Alarms Demonstrate knowledge of the alarms and the ability to troubleshoot the Aquarius accordingly. Explain alarm system signals - the status lights, the audible alarm and screen messages Demonstrate the use of the help screen Demonstrate and discuss Error Help Discuss possible causes of the following alarms. Discuss potential action taken to rectify alarm. Balance Alarm Access alarms pressure too high or too low Return pressures too high or too low High Pre-filter pressure High TMP High Pressure drop Temperature too high 9

10 Performance and Options Demonstrate competent and confident user knowledge of the machine and flexibility. Navigate to the History Screen. Identify where fluid loss can be found. Identify pressure records. Identify alarm history and discuss. Navigate to where you would need to go if you wanted to change the anticoagulant syringe and complete the change. Demonstrate the recirculation procedure. When would this be used and why? Reconnect to treatment mode. Perform and change of therapy eg : CVVHDF to CVVH and why you may want to do this. Circuit take down and Shut Down User to demonstrate cessation of therapy, safe and competent removal of the circuit and machine shut down. Identify reasons for electively taking down the circuit. Navigate to where circuit take down and machine shut down can be located. Can demonstrate safe and effective pressure removal from the circuit. Can identify appropriate circumstances when you may or may not return the patient s blood. Demonstrate removal of circuit according to the user manual. See criteria below. 10

11 Shut down (continued) Demonstrates End Treatment Correct equipment collected for disconnection 1L bag 0.9% saline 1 x single spike 1 x dressing pack 2 x 10ml 0.9% saline amps 2 x 10ml syringes 2 x 2ml syringes Heparin to hep-lock vascath Clamp and disconnect the access line Connect the access line to a bag of Normal Saline using a spike Follow the prompts on the screen Unclamp the access line and press the blood pump to start reinfusion of blood back to patient. Disconnect return line and reconnect to return chamber air port. Unclamp. Circuit Removal Identify pressures for safe removal of the Aqualine circuit. What do these pressures mean and how could these pressures influence your decisions? Ensure all the clamps on the access and return lines are off. Flush vascath lumens with Normal Saline and Heparin lock both lumens with Heparin according to unit protocol. Open the pump doors 11

12 Circuit Removal (continued) Remove the filtration tubing from the filtrate pump in the direction of the arrow then remove the filtrate pressure dome from the filtrate sensor. If return pressure <400mmHg remove the pressure dome from pressure sensor. Is the return pressure >400mmHg? Decrease the pressure by connecting a syringe to the top of the return chamber and fill the syringe with fluid until the pressure on the screen is below 400mmHg. Remove the return pressure dome from the return pressure sensor. Carefully remove the blood pump tubing by rotating in the opposite direction (anti clock wise) Is the access pressure >400mmHg? Decrease the pressure by connecting a syringe to the access infusion port before the access sensor and fill with fluid until the value is below 400mmHg. Remove the access pressure dome from the access sensor. Is the TMP >200mmHg? Decrease pre-filter pressure by connecting a syringe to the pre dilution port and fill the syringe with fluid until the TMP is below 200mmHg. Proceed with complete removal of the Aqualine circuit and all the bags from the machine Select Aquarius off on the screen to turn off the machine. All equipment must be removed from the Aquarius and scales before the machine is switched off. Failure to remove circuit and bags from the machine prior to machine shut down will constitute a failure of this section of competency. Dispose of equipment according to unit policy and OH&S guidelines. Ensure patient is comfortable 12
