Fresenius 5008 Machine Procedure Manual
The Fresenius 5008 machine is a hemodialysis system that offers various modes of therapy, such as high-flux hemodialysis, online hemodiafiltration (HDF), and online hemofiltration (HF). The machine is designed to provide high-quality and individualized treatment for patients with chronic kidney disease. The machine has several features that enhance safety, efficiency, and comfort, such as the AutoSub plus function, the Venous Access Monitor (VAM), the Blood Temperature Monitor (BTM), and the bibag system .
This article will provide a brief overview of the procedure manual for the Fresenius 5008 machine, which covers the following topics:
- Starting system and set-up
- Preparing and connecting the extracorporeal blood circuit (EBC)
- Preparing and connecting the dialysate circuit
- Starting treatment
- Monitoring treatment
- Ending treatment
- Cleaning and disinfection
- Troubleshooting and maintenance
The procedure manual is based on the operating instructions and the service manual of the Fresenius 5008 machine . The manual is intended for trained and qualified personnel who are familiar with the principles and practice of hemodialysis. The manual is not a substitute for the manufacturer's instructions, but rather a supplement that provides additional information and tips. The manual assumes that the user has access to the necessary equipment, supplies, and accessories for the Fresenius 5008 machine.
Starting system and set-up
The first step in using the Fresenius 5008 machine is to start the system and set up the parameters for the desired therapy mode. The following steps summarize the procedure:
- Switch on the main power switch at the rear of the machine.
- Select the language and confirm with OK.
- Select either Treatment or Disinfection from the main menu.
- Connect the concentrate lines and the bibag to the corresponding ports on the machine. Ensure that the correct concentrate type is selected in the dialysate menu.
- The T1 test will start automatically. This test checks the conductivity, temperature, and pressure sensors of the dialysate circuit. Wait until the test is completed.
- Open the EBM doors and follow the on-screen instructions for lining. Connect the arterial line first, ensuring that a sound is generated when inserting the red alpha clip into the blood pump segment. Then connect the venous line, ensuring that a sound is generated when inserting the blue alpha clip into the SafeLine segment.
- Select either HDF or HF from the therapy menu. Adjust the therapy parameters according to the prescription and confirm with OK.
- The T2 test will start automatically. This test checks the functionality of the blood pump, SafeLine, BTM, VAM, online pumps, and ultrafiltration. Wait until the test is completed.
- The system is now ready for EBC connection.
Preparing and connecting the extracorporeal blood circuit (EBC)
The next step in using the Fresenius 5008 machine is to prepare and connect the EBC to the patient's vascular access. The following steps summarize the procedure:
- Prime the EBC with saline solution. Use the prime function on the machine to fill the EBC with saline until all air bubbles are removed. Check the pressure and conductivity values on the screen.
- Connect the heparin pump to the heparin line. Set the heparin dose and bolus according to the prescription and confirm with OK.
- Prepare the patient's vascular access. Use aseptic technique to insert two needles or catheters into the patient's fistula or graft. Secure the needles or catheters with tape or dressing.
- Connect the arterial and venous lines to the patient's needles or catheters. Ensure that the clamps are closed and that there are no kinks or twists in the lines.
- Open the clamps on the arterial and venous lines. Press OK on the machine to start blood flow. Adjust the blood flow rate according to the prescription and confirm with OK.
- The VAM will start automatically. This function monitors the venous pressure and detects any disconnection or infiltration of the venous needle or catheter. Follow the on-screen instructions to perform a VAM test. Wait until the test is completed.
- The BTM will start automatically. This function monitors the blood temperature and adjusts the dialysate temperature accordingly. Follow the on-screen instructions to perform a BTM test. Wait until the test is completed.
- The EBC is now connected and ready for treatment.
Preparing and connecting the dialysate circuit
The next step in using the Fresenius 5008 machine is to prepare and connect the dialysate circuit to the EBC. The dialysate circuit consists of the dialyzer, the online filter, and the online fluid line. The following steps summarize the procedure:
- Select the dialyzer type from the dialyzer menu. Confirm with OK.
- Connect the dialyzer to the EBC. Ensure that the red port of the dialyzer is connected to the red port of the EBC, and that the blue port of the dialyzer is connected to the blue port of the EBC.
- Connect the online filter to the online fluid line. Ensure that the white port of the online filter is connected to the white port of the online fluid line, and that the black port of the online filter is connected to the black port of the online fluid line.
- Connect the online fluid line to the machine. Ensure that the white connector of the online fluid line is inserted into the white port of the machine, and that the black connector of the online fluid line is inserted into the black port of the machine.
- The T3 test will start automatically. This test checks the functionality of the dialyzer, online filter, and online fluid line. Wait until the test is completed.
- The dialysate circuit is now connected and ready for treatment.
Starting treatment
The next step in using the Fresenius 5008 machine is to start the treatment mode. The treatment mode can be either HDF or HF, depending on the prescription and the patient's preference. The following steps summarize the procedure:
- Press the Start button on the machine to start the treatment mode. The machine will display the therapy parameters and the treatment time.
- Adjust the ultrafiltration rate and the sodium profile according to the prescription and the patient's condition. Confirm with OK.
- Adjust the substitution rate and the substitution fluid type according to the prescription and the patient's condition. Confirm with OK.
- The AutoSub plus function will start automatically. This function optimizes the substitution rate and fluid type based on the patient's hematocrit and blood volume changes. Follow the on-screen instructions to perform an AutoSub plus test. Wait until the test is completed.
- The treatment mode is now started and running.
Monitoring treatment
The next step in using the Fresenius 5008 machine is to monitor the treatment progress and the patient's condition. The machine provides various indicators and alarms that help the user to ensure the safety and quality of the treatment. The following steps summarize the procedure:
- Check the screen regularly for the treatment parameters and the treatment time. The screen displays the blood flow rate, dialysate flow rate, ultrafiltration rate, substitution rate, blood pressure, blood temperature, conductivity, and hematocrit.
- Check the patient regularly for any signs of discomfort, such as nausea, cramps, headache, dizziness, or chest pain. If the patient experiences any symptoms, adjust the therapy parameters accordingly or stop the treatment if necessary.
- Check the EBC regularly for any signs of clotting, air bubbles, leaks, or disconnection. If any problem occurs, follow the on-screen instructions to resolve it or stop the treatment if necessary.
- Check the dialysate circuit regularly for any signs of contamination, leaks, or disconnection. If any problem occurs, follow the on-screen instructions to resolve it or stop the treatment if necessary.
- Check the machine regularly for any alarms or warnings. The machine will alert the user with audible and visual signals if any abnormality is detected. If any alarm or warning occurs, follow the on-screen instructions to resolve it or stop the treatment if necessary.
- The treatment is monitored and running.
