A dialysis machine venous pressure alarm
the reason:
1, hematoma at the venipuncture.
2. The venous puncture needle is blocked by blood clots or fat droplets; the needle tip resists the blood vessel wall.
3. The venous puncture needles and venous line clamps are not opened when the venous line circuit is obstructed and twisted and folded or when dialysis starts.
4, patients with venous stenosis, hardening. The patient was placed in a lateral position to press the veins.
5, the patient's blood flow is too high, and the veins are too thin and elastic.
6, the patient is in a high coagulation state.
7, arterial flow is not good, no heparin dialysis or insufficient dosage, causing filter clogging.
deal with:
1. Carefully select blood vessels before puncture to avoid scars and hematomas.
2, check the venous puncture needle bleeding or hematoma.
3, adjust the needle position or needle oblique, if necessary, re-puncture.
4. Check for variability, folding, or compression of the venous line. The puncture needle and the line clamp are open.
5, if you suspect that patients with venous stenosis, feasible angiography or color Doppler ultrasound.
6. Avoid connecting the puncture tubing to the arterial puncture needle. Take care to avoid venous pressure when the patient turns over.
7. Rinse the venous line with saline to identify clotting sites. Observe whether there is any change in the color of the blood in the filter with or without blood clots, and adjust the amount of heparin in time. If there is no obvious change in the color of the filter and there is no blood clot, you can take a little saline to check the puncture needle for clogging. If there is a large blood clot in the filter and the transmembrane pressure is normal, the color of the dialyzer is normal and the venous line can be replaced immediately.
Second, dialysis machine venous pressure alarm
the reason:
1. The venous line is not closely connected with the puncture needle or the puncture needle is released.
2, arterial pipeline pressure, twisted, folded.
3. Patients with poor vascular conditions or unskilled puncture techniques lead to poor arterial flow. After blood pump ruptured blood vessel.
4, the dialyzer serious coagulation.
5, venous pressure sensor failure, venous pressure measurement mouth clip is not open.
6, protective cover damaged or blocked.
7, protective cover into the water.
deal with:
1. Check whether the pipe is connected tightly with the puncture needle and whether the puncture needle has come out.
2, check the venous pressure to determine whether the mouth clip is open, whether there is distortion of the arterial line, folding, pressure.
3, if the arterial flow is not good, you can adjust the puncture site or postoperatively puncture a needle to increase blood flow.
4. If the pipeline is damaged, it should be replaced immediately. If the dialyzer coagulates, the dialyzer will be replaced immediately.
5. Observe the patient's discomfort, such as cold sweat, pulse speed, arterial flow rate difference and blood pressure drop, etc., and if they find that immediately reduce the ultrafiltration volume and treat hemodialysis hypotension complications.
6. Check whether the venous pressure protection cover is abnormal before the machine is replaced; if the pressure sensor fails, notify the maintenance personnel immediately.
7. Check whether the protective cover is filled with water, if the water is pushed back with the syringe.
Third, dialysis machine air alarm
the reason:
1, the pipeline before the blood pump ruptured.
2. The arterial end tube is detached from the puncture needle or the arterial needle slides out of the blood vessel.
3. The clamp between the infusion port and the infusion set is not clamped.
4. When the arterial pressure is monitored, the arterial pressure tube clamp is not clamped.
5, arterial pressure monitor arterial pressure interface is not tight convergence, the occurrence of leakage. The arterial flow is poor and produces a lot of air bubbles.
6, abnormal air monitoring, induction failure. Air bubbles adhere to the wall of the veins. Venous canal fluid level is too low.
deal with:
1. Turn off the blood pump and check whether the above conditions are in the arterial line.
2, find out the reason, immediately after the correction of the open blood pump, low blood flow, bomb venous line, so that the bubble into the vein pot, the pop-up after the blood flow will be adjusted to the normal value.
3, check the blood tube before the machine is damaged.
4. If the pipeline is found to be damaged during the dialysis process, the pump should be replaced immediately.
5. Check whether the sensor is abnormal and correct it in time.
6. Adjust the page height in the vein pot, which is generally two-thirds of the entire vein pot.
Four, dialysis machine leak alarm
the reason:
1, the dialyzer membrane rupture.
2. A large amount of gas in the dialysate forms a false alarm.
3, the dialysate tube interface and the dialyzer connection is not tight.
4. Bad bypass degassing during pre-shooting.
5, blood leak detector abnormal failure.
deal with:
1. The color of the dialysate at the outlet of the dialyzer's arterial end dialysate can be visually observed first to see if the color of the dialyzed solution turns red or not. If the membrane is broken, the dialyzer should be replaced immediately.
2. Observe the location of air and air bubbles. A large amount of air bubbles in the dialysate inlet pipe suggest poor degassing of the dialysate.
3. Divert the bypass gas when the dialyzer is pre-punched.
4. If there is no leakage of blood, air or air bubbles, the blood leak detector may have dirt precipitation. If the patient changes the dialysis machine in time for treatment, it should be immediately repaired by the technician.
V. Dialysis Electromechanical Conductivity Alarm
the reason:
1. The type of concentrate is wrong, the composition of the concentrate is incorrect, and the A/B solution is reversed.
2. The suction tube of the concentrate is blocked, leaks, or inhales too much air due to the use of the concentrate, causing obstruction of the pipette.
3, lack of water flow or water pressure, dialysis water substandard.
4, the alarm line is set too high or too low, conductivity test system failure.
5, the machine's concentration ratio system failure, such as the concentration of the pump tube aging, deformation and so on.
6, machine disinfection, decalcification, flushing is not complete.
deal with:
1. Check that the concentrate is correct, or replace the barrel with concentrate.
2. Lift the pipette to see if the concentrate is inhaled. If inhaled, check the dialysate flow and alarm line settings are correct, if not inhaled, you can reconnect the concentrate interface back to the machine to flush or knock the filter to remove the filter air.
3, if the pump tube aging deformation should immediately replace the pump tube, such as machinery failure should immediately notify the technical staff maintenance.
4. After the maintenance of the machine's conductance, the concentration of the dialysate must be checked through the laboratory. It can be used after being normal.
Sixth, dialysis machine dialysate temperature and flow alarm
the reason:
1. Temperature monitoring failure causes the dialysate temperature to exceed the set point.
2. Failure of the dialysate flow control system leads to an unstable flow of dialysate.
3, water or dialysis water pressure is insufficient.
deal with:
1, check whether the dialysis water supply is sufficient.
2, the failure of the machine in a timely manner to notify technical personnel maintenance.
Seven, dialysis machine transmembrane pressure alarm
the reason:
1, the patient's ultrafiltration volume is too small.
2. Increase or decrease the amount of ultrafiltration within 30 minutes before the end of dialysis, so that the ultrafiltration rate is too high or too low in the unit time to cause the transmembrane pressure to be high or high or low alarm.
3. Patients with poor blood flow in a hypercoagulable state or blood clots in the dialyzer cause partial or complete coagulation of the dialyzer.
4. The dialysate tubes are compressed and folded with deposits or foreign matter entering the blockage.
5. The quick connector of the dialyzer leaks or is not tightly connected.
6, the dialysate pressure sensor is damaged.
7, lack of water for dialysis or stop water.
deal with:
1. Do not increase or decrease the amount of ultrafiltration in excess of 30 minutes before the end of dialysis.
2. Check if the quick connector is tightly connected with air or not, and replace it if damaged.
3, check whether the dialysate pipeline is compressed and unobstructed.
4. In case of increased transmembrane pressure, check whether the color of the dialyzer becomes darker. If it becomes dark, change the dialyzer immediately if the venous pressure is normal.
5. If there is no anticoagulant dialysis, return the blood immediately.
6. If the color does not change, you can flush the tubing with saline to see if it is clotting or which part of it is clotting.
7, the machine fails, such as dialysate pressure sensor failure, etc., should immediately ask the technical staff to repair.
Eight, dialysis machine disinfectant shortage alarm
the reason:
1, a. The lack of dialysis machine disinfectant
2, b. leaks into the inlet pipe

3, c. Check for power failure
4, d. re-sterilization.
Nine, dialysis machine blood concentration alarm
Cause: The amount of ultrafiltration per unit time is too large.
deal with;
1, check whether the amount of dehydration is set correctly
2, check whether the dialysis time is set correctly
3, carefully check the treatment data before the machine.
Tenth, heparin pump overload alarm
the reason:
1. Heparin has not been replaced in time due to the use of heparin
