Venous hypertension alarm
Jingmai Yakao
When the venous pressure is high, the first thing to do is to keep the pipeline unobstructed, and replace the isolator in time when blood or water enters. If the ultrafiltration is high, the dialysis time can be extended appropriately. Dialyzers without heparin cause clotting and resistance, so blood cannot return to the body. At this point, the clot should not be returned to the patient. If the tubing is all clotted, stop the pump and replace the dialyzer and tubing, flush the IV tubing with saline, and identify the site of the clotted blockage.

At this point, you will want to check the venous line for holes in the ports and joints, the correct venous pressures, and clogged filters, and check the alarm limits for venous pressures. High ultrafiltration may result in lower venous pressure.
Arterial low pressure alarm

At this time, check the arterial pipeline for air ingress and pipeline pressure; if the arterial blood pressure doesn't continue to fall after reducing the blood flow, it means that the arterial flow is insufficient, mostly because of arterial stenosis or improperly positioned arterial needles. When a patient's blood pressure drops, arterial blood flow also drops, so blood pressure should be routinely monitored.
Air alarm
Controlling air to preserve Jing
When the air alarm is activated, check to see if there is a large amount of air in the machine entering the blood pathway. Arterial depressions create air bubbles, dialysate bubbles enter the bloodstream, and the venous line can deteriorate; if no air bubbles are found in the bloodstream, reinstall the venous jug and tubing and change the detection position so that the venous jug and tubing are properly connected to the air detector probe. A small amount of water or cream can also be used to fill the gap between the wall of the tubing and the probe. Check that the line fittings are tight, that the clamps on the infusion end are tight, and that the line is not damaged or leaking, and replace it immediately if it is damaged. Do not enter too much air during blood and saline transfusions. In the event of a severe vacuum in the dialysis system, especially if the IV jug is empty, do not attempt to pump out air bubbles or infuse blood back into the patient while dialysis continues.
Conductivity Alarm

At this point, check for the correct concentration by lifting the concentrate pipette and observing if the concentrate is aspirated. If aspirated, check that the dialysate flow rate is correct. If not, check that the concentrate tubing is not twisted or kinked, that the filter is not clogged, and that the connections are not leaking.
Blood leakage alarm

Blood leakage alarm, first check whether the dialyzer has a rupture of the membrane, a large amount of air into the dialysis fluid, blood leakage detection has dirt deposits, the detector is not working. Treatment measures are to observe the color of the dialysate and take a sample from the dialysis outlet if necessary. If the membrane ruptures, this usually occurs when the ultrafiltration rate is too high and the dialysate tubing is loose from the dialyzer connection. Poor degassing of the dialysate can also produce large amounts of air bubbles. If there is no blood leakage and no air or bubbles, dialysis should be stopped and the machine cleaned. If necessary, the blood leakage detector should be removed and cleaned before use.
Therefore, to prevent adverse events from hemodialysis machines, it is important to standardize the configuration of dialysate, dialysate water, and concentrates.
Hemodialysis machines differ from other commonly used electronic devices. During the dialysis process, the slightest problem with each unit can cause downtime and affect the normal course of treatment. Therefore, to ensure the normal operation of the machine, it is very important to carry out strict and meticulous maintenance and regular inspection and maintenance management. Routine maintenance of dialysis machine should be carried out in conjunction with the machine manual and in the off state. The surface of the machine should be kept clean and free from dust, liquid traces and blood stains. Dampen the cloth with water, clean the cannula with flexible detergent if necessary, disinfect the venous clamps and optical sensors, and keep the blood monitoring, bubble monitoring and air monitoring places clean and bright to avoid false alarms. If there is contamination, test with a semi-wet cotton swab
