About This Manual…
About this manual…
The purpose of the 2008K Hemodialysis Machine Operator’s Manual is to instruct qualified patient-care staff in the function, operation, and maintenance of the 2008K hemodialysis machine. It is not intended as a guide for performing hemodialysis, a medical treatment that should only be performed under the supervision of a licensed physician.
This manual is organized to systematically guide a patient-care specialist through the set up, operation, and clean up of the 2008K hemodialysis machine in daily use. The book begins with an overview that introduces the operator to the major components and describes how they are organized on the machine. Next, the operator is guided through a daily set-up procedure. Once the machine has been prepared for daily use, a step-by-step guide to preparing the machine for a patient-specific treatment is provided. The operator is then provided a tour of the various treatment screen functions useful in monitoring the treatment, followed by instruction in terminating treatment and post-treatment clean up. Also included are sections on troubleshooting, maintenance, and treatment options.
The organization of the 2008K Hemodialysis Machine Operator’s Manual is as follows:

About Hemodialysis…
Indications
Hemodialysis is prescribed by physicians for patients with acute or chronic renal failure, when conservative therapy is judged inadequate. Dialysis therapy may be intermittent or continuous.
Contraindications
There are no absolute contraindications to hemodialysis, but the passing of a patient’s blood through an extracorporeal circuit may require anticoagulation to prevent blood clotting. In addition, the parameters of dialysis should be optimized to avoid discomfort to the patient.
Many patients are taking medicinal therapy prescribed by their physicians. Due to the dialysis treatment, some of the medication may be removed from the patient’s blood thereby lowering the therapeutic level in the blood. In other cases, medications may not be excreted as quickly as expected with patients with renal insufficiency and the level may be higher than expected. Therefore, the prescribing physician should determine the appropriate dosage of the medicine to obtain the desired medicinal response in the patient.
Some Side Effects of Hemodialysis
Dialysis therapy occasionally causes hypovolemia, hypervolemia, hypertension, hypotension and related symptoms, headache, nausea, cramping or other muscular discomfort in some patients. Hypothermia, hyperthermia, itching, anxiety, convulsions, seizure, and other neurologic symptoms associated with dialysis dementia may also be manifested by the patient. These symptoms are thought to occur if the patient’s blood volume or electrolyte balance is not maintained within acceptable limits. Other, more serious, complications arising from dialysis, such as hemorrhage, air embolism, or hemolysis, can cause serious patient injury or death. The prescribing physician must understand that prescribing insufficient bicarbonate may contribute to metabolic acidosis; excessive bicarbonate may contribute to metabolic alkalosis. Both conditions are associated with poor patient outcomes, including increased risk of mortality. Proper control of all elements of dialysis may prevent or control these physiological reactions or complications.
Pyrogenic reactions may occur which can result in patient injury. Generally it is thought that these may be controlled by maintaining the dialysate solution within the chemical and bacteriologic limits (see Water Quality on page 218 of the “Machine Specifications” section for more information). Failure to use these standards for water can also lead to accumulated toxic effects. A regular program for disinfection and testing of the water treatment system, piping, inlet lines, filters, concentrate feed containers or system, and the dialysate delivery machine must be established and followed. This program will vary from facility to facility.
2008K Hemodialysis Machine Operator’s Manual Rev P |

About This Manual…
Infections or pyrogen reactions may also result from contamination of the extracorporeal circuit or inadequate procedures used to reuse dialyzers.
Allergic reactions to chemical disinfectants may occur if insufficient procedures are used to remove or maintain the residual disinfectant at acceptable levels. Chemical disinfectants are used for dialyzer disinfection, machine disinfection, or for disinfection of water treatment and distribution systems.
All blood connections must be made using aseptic technique.
All tubes and connections must be secured and closely monitored to prevent loss of blood or entry of air into the extracorporeal circuit or errors in the ultrafiltration control system. The patient may require blood transfusion or other medical intervention to prevent respiratory or cardiac disorders if these occur.
The patient’s blood pressure and general physical status must be closely monitored during dialysis in order to initiate appropriate remedial measures or therapy. Of particular importance is the control of the patient’s serum potassium level to prevent cardiac dysrhythmia and the patient’s blood clotting time to prevent clotting disorders.
These instructions are for the 2008K hemodialysis machine. The machine must only be operated in accordance with these instructions. All operators of this machine must be thoroughly trained and have read this entire manual and any applicable appendices before using the machine. Improper care/use of this device may result in serious patient injury or death.
Blood Pressure Module Contraindications
The following are generally accepted contraindications for using a timed automatic blood pressure instrument utilizing the oscillometric principle:
Use of a heart lung machine
Peripheral circulation problems
Severe arrhythmia
Ectopic beats
Convulsions
Spasms
Tremors
Tachycardia
Use of incorrectly sized blood pressure cuffs may result in inaccurate blood pressure readings.
This is a guideline only. Final determination of the suitability of any medical instrument for use with any patient is the responsibility of the treating physician.

General Warnings
General Warnings
This section contains general warnings statements regarding the use and maintenance of the 2008K hemodialysis machine. It is not a complete summary, and additional warning statements specific to pertinent topics can be found within this manual.
Water
Warning! Connect water inlet according to the specifications for the machine. For further information, see Appendix B, “Machine Specifications.” The correct ionic concentration and bacterial quality can generally be achieved in the dialysate only with treated water that meets water quality standards (see Water Quality and Dialysate Quality on page 218 of the “Machine Specifications” section for more information). Be sure that all specifications are satisfied. The water source must be monitored periodically to detect fluctuations in water composition and quality that could have an adverse effect on the patient or dialysate delivery machine. Particular attention must be taken for chemicals such as aluminum, chlorine, and chloramine, as these chemicals can cause complications in dialysis patients.
Warning! Comply with all local regulations in respect of separation of devices in the water supply in case of back siphonage; an air gap must be created between the machine’s drain line and its drain.
Concentrates
Warning! The specific acid and bicarbonate concentrates, including the sodium, bicarbonate, and electrolyte compositions, must be prescribed by a physician.
Warning! Many concentrate types are available for use in dialysate delivery machines. Concentrates contain various amounts of dextrose, potassium, calcium, sodium, chloride, magnesium, and other components. Most concentrates are designed as a two-part system of acid and bicarbonate solutions which are mixed in the machine with water. Even within the subgroup of bicarbonate type concentrates, there are at least four methods of compounding the solutions. Each of these methods requires special calibrations or setups. Certain methods are not supported. It is mandatory that the acid and bicarbonate types be matched to each other. Be sure to use compatible solutions, labeling, and setups. These setups include machine calibration, special adapters for certain concentrate types, correct setting of concentrate option, and labeling. Failure to use the properly matched solutions and machine calibrations may allow improper dialysate to be delivered to the patient, resulting in patient injury or death. Verify composition, conductivity, and pH after converting to a different type of concentrate.
Warning: Acid concentrate, bicarbonate concentrate, and water must be of the appropriate quality to ensure safety and performance of the final dialysate are met (see Concentrate Quality on page 218 of the “Machine Specifications” section for more information).
Warning! Connection to a central acid or bicarbonate feed system requires the installation of certain mechanical parts. Contact Fresenius USA, Inc. for more information.

General Warnings
Warning! Bicarbonate and acid concentrates intended for other dialysate delivery machines will deliver safe dialysate solution only if the machine is set up for them. The selection of other dialysate concentrate types must be done by a qualified, authorized person. The 2008K hemodialysis machine can be set up for various concentrate types. Use Table 33 in Appendix B to ensure that you have compatible concentrates and configurations.
Warning! Acid concentrate products are used as one component in mixing dialysate bath. These acid products contain chemical compounds that, after mixing, yield acetate (and citrate in certain products) in the dialysate. (Please refer to the acid concentrate product labeling for specific acetate/citrate amounts.) After diffusion across the dialyzer membrane, acetate (and citrate when present) is metabolized by the liver to serum bicarbonate and adds to the serum bicarbonate that separately results from the diffusion of dialysate bicarbonate across the dialyzer membrane. During dialysis, the dynamic of diffusion and concentration gradients prevent serum bicarbonate concentration from exceeding the dialysate bicarbonate concentration. The bicarbonate concentration of the dialysate is the “bicarbonate” setting on the dialysis machine, and is the bicarbonate dose prescribed by the physician. On the 2008 series hemodialysis machines, the bicarbonate dose may be set in a range between 20 and 40 milliequivalents per liter, but may be set in different ranges in other machines.
When the dialysis session terminates, acetate (and citrate when present) that has not yet metabolized may remain in the blood and will be converted to serum bicarbonate after diffusion ceases, without possibility of diffusion out of the blood. The post dialysis metabolism of acetate (and citrate when present) could thus briefly increase serum bicarbonate concentration above the prescribed bicarbonate concentration of the dialysate. Physicians should consider this possibility in prescribing bicarbonate dose.
Prescription of insufficient bicarbonate may contribute to metabolic acidosis; excessive bicarbonate may contribute to metabolic alkalosis. Both conditions are associated with poor patient outcomes, including increased mortality risk.
Warning! Incorrect composition will result if the acid concentrate nozzle is not connected to the appropriate acid concentrate or the bicarbonate concentrate nozzle is not connected to the appropriate bicarbonate solution. The acid and bicarbonate concentrates must match those selected in the Dialysate screen. Patient injury or death may occur if incorrect dialysate solution is used. Fresenius USA, Inc. recommends the operator use the concentrate containers provided with the machine. These containers, being of different size and shape, help to reduce the chances of mismatching the acid and bicarbonate concentrates.
Warning! The operator should always check conductivity and approximate pH of the dialysate with an independent device prior to initiating treatment and whenever concentrates are changed during operation.
Warning! Use of an acid concentrate intended for a 1:44 mix ratio in any 1:34 proportioning dialysate delivery machine may result in a dialysate solution with a normal conductivity but without a physiological buffer. There may be no alarms in this event. Use of this improper dialysate solution may cause patient injury or death.
Warning! The machine must be labeled to indicate the type of concentrate for which it is configured. Check the composition (i.e., Na, Cl, K, Ca, Mg, HCO3) and pH of the dialysate solution after the machine is installed or after the machine is modified for different concentrate types. Check the conductivity and approximate pH of the dialysate solution with an independent device before initiating dialysis. Improper conductivity or pH could result in patient injury or death.

Cellular phones and WiFi connected devices may be conditionally allowed. However, if any interference is noted, such as false pressure readings that disappear when the external signal is removed, it is recommended to move the cellular phone at least ten feet away from the 2008K hemodialysis machine when making or receiving phone calls. If a WiFiconnected device (e.g. laptop computers, tablet devices, smartphones) is found to cause interference, it is recommended to use that device at least four feet away from the 2008K hemodialysis machine.
For exact separation distance recommendation, please refer to the Manufacturer’s EMC Declaration statement on page 224.
Warning! Never perform maintenance when a patient is connected to the machine. If possible, remove the machine from the treatment area when it is being serviced. Label the machine to ensure it is not accidentally returned to clinical use before the service work is completed. Disinfect the machine and test the dialysate for acceptable conductivity and pH values before returning the machine to clinical use. Always test the machine when maintenance is completed.
Warning! The electrical source must be single phase, three-conductor type provided with a hospital grade receptacle and a ground fault interrupter at 120 volts, 60 Hz. The proper polarity and ground integrity must be initially checked and maintained. Failure to do so may result in electrical shock or burn to the operator or patient. The machine must be plugged directly into the electrical outlet; extension cords and power strips are prohibited.
Warning! Shock hazard. Do not remove covers. Refer servicing to qualified personnel. Replace fuses only with the same type and rating.
Warning! Do not install the 9-Volt battery backwards in the machine, as it will damage the “No Power” alarm.
Warning! Proper functioning of the machine must be verified prior to initiating treatment. Unidentified malfunctions or alarm failure could potentially expose a patient to a serious health risk. Alarm limits for the arterial pressure monitor, venous pressure monitor, and transmembrane pressure (TMP) monitor are automatically set and delayed for pressure stabilization. Alarm limits for temperature and conductivity are calculated for the dialysate composition and may be somewhat adjusted by the operator. These must be maintained within safe physiological limits as specified by the prescribing physician.
Warning! Transducer protectors should be used between transducers and each pressure monitor line of the extracorporeal system to prevent the internal transducer protectors from getting wet. Wet transducer protectors must be replaced, as they will cause inaccurate pressure readings. If the external transducer protector and the internal transducer protector become contaminated with blood, the transducer protectors must be replaced and the transducer and associated parts must be disinfected or replaced.

General Warnings
Warning! Possible Explosion Hazard if used in the presence of flammable anesthetics.
Warning! A new, sterile transducer protector should be placed on all the air connections from the drip chambers to the machine pressure monitor ports. This will prevent contamination of the machine and filters air that enters the chambers through the monitor lines. If the transducer protector should get wet and air is not able to pass, replace the transducer protector and clear the monitor line.
Warning! The machine is compatible with a number of venous lines. The Level Detector module must be calibrated for the model venous line being used. In addition, verify that the venous line clamp is capable of fully occluding the model of bloodline that your facility uses.
Warning! To avoid damaging the equipment or personal injury, internal adjustments to the blood pressure module should only be made by a qualified technician.
Warning! Check all bloodlines for leaks after the treatment has started. Keep access sites uncovered and monitored. Improper bloodline connections or needle dislodgements can result in excessive blood loss, serious injury, and death. Machine alarms may not occur in every blood loss situation.
Warning! The dialysate path is a closed fluidics system. Discontinue use immediately if a fluid leak is detected. Do not attempt to administer or continue dialysis treatment with a machine which has a fluid leak, this could result in excessive fluid removal from the patient leading to serious injury or death. System leaks may also pose a slip-and-fall hazard. Clean up spills immediately.
Caution: System leaks may occur. Unattended operation of the machine (for example, during disinfection at night) may result in flooding and can cause property damage. Clean up spills immediately.
Caution: Be careful not to tip the machine when rolling over uneven surfaces. Push the machine from the middle when moving it.
Caution: Do not squeeze the blood pressure cuff when deflating it. Squeezing the blood pressure cuff may damage the machine's internal blood pressure module.
Note: A smoke detector should be properly installed in the room used for dialysis. Follow the manufacturer’s instructions. The alarm should be tested according to the manufacturer’s instructions. Replace the battery as specified.
Note: You must follow all environmental regulations regarding waste disposal and eventual machine disposal. Contact your clinic for more information. Prior to the disposal of your machine, any possible risk of infection from blood borne pathogens must also be eliminated by appropriate disinfection.
Note: The temperature of the bloodline and the durometer of the tubing affect the ability of the bloodline/blood pump system to prime during setup. Cold tubing may not prime as readily as warm tubing.
Fresenius Medical Care manufactures bloodlines for use with the model 2008K hemodialysis machine. The performance of bloodlines not manufactured by Fresenius Medical Care cannot be guaranteed by Fresenius Medical Care and are therefore the responsibility of the prescribing physician.

Chapter 1
Overview
The 2008K hemodialysis machine is designed to perform hemodialysis in hospitals, dialysis clinics, and at home with a qualified operator other than the patient. It can be used for patients suffering chronic or acute renal failure.
Function of the 2008K hemodialysis machine
The 2008K hemodialysis machine is designed to provide hemodialysis treatment by controlling and monitoring both the dialysate and extracorporeal blood circuits.
In the extracorporeal blood circuit, the blood is continuously circulated from the patient through a dialyzer, where toxins are filtered out through a semi-permeable membrane, before being returned to the patient. During this process, the extracorporeal blood circuit is monitored for venous and arterial blood pressures, and for the presence of air and blood. The 2008K hemodialysis machine can also administer heparin evenly throughout the treatment.
In the dialysate circuit, the dialysate concentrates are mixed with purified water, heated, degassed, and delivered to the dialyzer. Balancing chambers ensure that the incoming flow of the dialysate is volumetrically equal to the outgoing flow in order to control ultrafiltration from the patient.
Organization of the 2008K hemodialysis machine
The 2008K hemodialysis machine is designed for functional efficiency. The back of the machine houses the utility connections such as water source, drain, and electrical connections. By mounting them to the back, the water lines and power cord remain out of the way during treatment.
The front of the machine contains all of the controls the operator needs access to during hemodialysis. It can be broken down into three main sections. The top section contains the control panel and houses the computer that runs the treatment program. The middle section contains the modules used for the safe transmission of the blood to and from the dialyzer. Dialysate is the primary concern of the bottom section of the 2008K hemodialysis machine. Here the concentrates used to make up the dialysate are mixed and pumped to the dialyzer.
The following pages contain front and rear views of the 2008K hemodialysis machine and a brief description of the machine’s features. You should familiarize yourself with the location and purpose of these features.

The Control Panel
The control panel (see Figure 3) is located at the top, front of the 2008K hemodialysis machine and contains key pads that allow the user to control the operation of the 2008K hemodialysis machine. Located in the middle of the control panel is the touch screen that can display a variety of treatment screens which the operator uses to set treatment parameters and monitor the treatment.
The touch screen provides a means of setting the treatment parameters and monitoring the treatment and patient status during dialysis. The operator can access treatment screens and set treatment parameters by pressing specific, identified sites (buttons) on the screen. Most numbers and parameters selected on the touch screen must then be confirmed by pressing the CONFIRM key on the control panel. This feature was designed to prevent a change in a treatment value if the touch screen is accidentally bumped.

Prime the extracorporeal blood circuit. Pressing Prime will keep the blood pump running when air is sensed in the venous blood chamber and a level detector alarm is present (as is the case during initial set up when the blood circuit tubing is empty). The pump will run for:
Two minutes, or
Until an adequate fluid level is detected by the ultrasonic sensors in the level detector module, or
Until the volume set in Service Mode is reached.
Start an unscheduled, manual blood pressure measurement when the cuff is deflated, or instantly deflate the inflated blood pressure cuff.
Note: Certain versions of the blood pressure module require a 30 second delay between blood pressure measurements.
Turn the heparin pump on or off. When the heparin pump is on, the green, triangular light is illuminated. This light will flash when heparin pump is interrupted.
In the event of a blood leak or the detection of air in the extracorporeal blood circuit, the blood warning lights illuminate and are accompanied by an audible alarm. For detailed descriptions and instructions regarding remedial actions, see chapter 6, “Alarms and Troubleshooting.”
