Braun CRRT machine operation flow
1, plug in the power supply, turn on the machine power supply, and enter the "self"
Test "working status, working status is displayed in the upper right corner of the screen. (At this time, make sure that nothing is installed on the machine. If yes, delete all. ).
2. The machine automatically performs the following three self-tests. If the shutdown time is not long enough, items (2) and (3) will not appear. Ongoing self-check items, such as "ROM"
"Test" shows the next line in the working state, and the next line under the self-inspection item shows the corresponding self-inspection process.
(1) "ROM test": Perform a software check (CRC), and all six indicators on the panel are lit.
(2) "Display test": If it is correct, press the [EQ] key to confirm, and the alarm will sound for 2 seconds.
(3) "Empty load cell test": If it is empty, the value is between +60 and-60g, press the [EQ] key to confirm.
3. After the power-on self-test is completed, the machine automatically enters the "treatment selection" working state.
4. Select the treatment type, and then select Continuous.
5. Select the treatment item, select CVVH, and then press [EQ] to confirm. The machine enters the "ready" working state.
6. Skip the hardware self-check: press and hold V, BE and▲ at the same time, and press the [EQ] key to confirm.
7. Install the pipeline
[1], installed on the scale: (1) displacement liquid (conventional formula: NS3000ml+5%GS 1000ml+ calcium chloride 1g +25% magnesium sulfate).
3.2 ml).
(2) Ultrafiltrate collection bag.
2, install blood filter, vein end up.
[3] Install the arterial line (red). Connect the saline bag, PA, blood pump, heparin, PBE and blood filter.
[4], pretend to be a policeman selling official roads (blue). Connect to blood filter, PV, venous air monitor and venous clamp.
5], the installation of rehydration road (green). Connect to the liquid replacement bag, liquid replacement air monitor, PD 1, heater, arterial line (before replacement) or venous line (after replacement).
[6] Install the ultrafiltration pipeline (yellow). Connected to a blood filter (near the venous end), a blood leakage monitor, a PD2, an ultrafiltration pump and an ultrafiltrate collection bag.
8. Open all pipe clamps and conduct pre-flushing/self-inspection.
9. Apply black primer and start pre-washing. Turn on the blood pump according to the machine prompt, and the machine will automatically perform pre-flushing/self-inspection. After the self-inspection, the machine automatically flushes the pipeline. After washing is completed, the washing machine will have a music prompt and display "Ready" in the upper right corner of the screen.
Treatment (ready to enter treatment) ".
10. Parameters can be set during pre-flushing/self-checking/flushing. Black parameter
Set to enter the parameter setting screen. All the parameters of the machine have been automatically preset to the default values, and there is no special requirement to modify, mainly by setting the alternative process and UF.
Rate (net ultrafiltration rate) and cycle time (treatment time).
(1), press ▲ or ▼ to move the cursor to the data to be modified, and the data adjustable range will be displayed in the upper right corner of the screen.
(2) Press Enter once and the data will be highlighted, indicating that you are ready to modify this data.
(3) Press ▲ or ▼ to adjust the data to the required value.
(4) Press Enter again to indicate that the data has been changed. If necessary, press the EQ key to confirm that the data is normal and true.
(5) Repeat (1)-(4) Set other parameters.
(6) Press the Enter key three times quickly after (4) to exit the parameter setting screen.
1 1, press enter in black.
For treatment (entering treatment), press EQ key to confirm that the machine enters the treatment working state. First, I'm waiting to connect the patient (standby). The machine calibrates the blood leakage zero point. If the pipeline in the blood leakage monitor is full of liquid and there is no blood or air, press EQ to confirm.
12, connecting patients.
(1), blood pump;
(2) connecting the arterial line to the patient;
(3) Start the blood pump, and the blood flow is 50-60ml/min;
(4) Check whether the arterial pressure is within the allowable range;
(5) When the venous line can be connected to the patient, stop the blood pump and connect the venous line to the patient;
(6) Turn on the blood pump and adjust the blood flow to an appropriate value according to the patient's condition;
(7) Check the arterial pressure and static pulse pressure displayed on the screen.
13, after 2-3 minutes of blood circulation, if there is no alarm, blacken the treatment, enter the treatment operation and start the treatment timing.
14, pay attention to observe various parameters, and eliminate the alarm. Blacked out the grand total overview, and you can see the grand total. Blackening pressure
Overview (total pressure display) can view the filter pressure chart.
15, change the package. Changing the total weight of the scale without informing the machine (hanging the replacement liquid bag on the scale, taking anything off the scale, touching the items on the scale) will cause an alarm. When the package needs to be replaced:
(1), black package change (package change);
(2) changing the package;
(3), blackening therapy (treatment).
16, end of treatment.
(1) When the treatment is extinguished, the machine enters the working state of ending the treatment;
(2) Stop the blood pump. Disconnect the arterial line on the patient, connect the saline bag and start the blood pump;
(3) When enough saline is inhaled, take out the saline bag;
(4) Blood transfusion: when there is an air alarm, the blood pump will automatically stop, mute, blacken sadness, eliminate the prohibition of air alarm, and press EQ to confirm;
(5) Turn on the blood pump, and the blood pump will stop automatically after running for several seconds, and the blood or normal saline in the venous pipeline will just return to the patient's body;
(6) Remove the venous catheter on the patient and all consumables on the machine. Dispose of all used materials according to regulations;
(7) extinguish the new therapy and return to the working state of treatment selection.
