Understanding the dashboard of your dialysis equipment

Understanding the information displayed on a hemodialysis machine is crucial for ensuring a safe and effective treatment. Here's a breakdown of key aspects:

Key Monitoring Parameters:

• Blood Flow Rate (Qb):
  • This indicates the speed at which blood is being pumped from your body to the dialyzer.
  • It's essential to maintain the prescribed blood flow rate for optimal clearance of waste products.
• Dialysate Flow Rate (Qd):
  • This refers to the speed at which the dialysate solution (the cleaning fluid) is flowing through the dialyzer.
  • This also must be at the presribed rate to insure proper cleaning of the blood.
• Ultrafiltration Rate (UFR):
  • This measures the rate at which excess fluid is being removed from your blood.
  • Careful monitoring of the UFR is vital to prevent complications such as hypotension (low blood pressure).
• Arterial and Venous Pressures:
  • These readings indicate the pressure of blood entering and returning from the dialyzer.
  • Abnormal pressures can signal problems with the vascular access (fistula or graft) or the tubing.
• Dialysate Temperature:
  • The temperature of the dialysate solution is monitored to ensure patient comfort and prevent complications.
• Conductivity:
  • This measures the concentration of electrolytes in the dialysate, ensuring the proper balance of minerals in your blood.
• Air Detector:
  • This crucial safety feature detects the presence of air in the bloodline, triggering an alarm to prevent air embolisms.
• Blood Pressure and Heart Rate:
  • The machine often monitors these vital signs throughout the treatment.
• Heparin Delivery:
  • If heparin is used, the machine monitors the delivery rate of this anticoagulant, to prevent blood clotting in the extracorporeal circuit.

Why Monitoring Is Important:

• Safety:
  • Monitoring ensures that the treatment is proceeding safely and that potential complications are detected and addressed promptly.
• Effectiveness:
  • Monitoring helps to ensure that the prescribed amount of waste products and fluid is being removed from your blood.
• Patient Comfort:
  • Monitoring helps to prevent discomfort and side effects such as muscle cramps, nausea, and dizziness.

What to Do During Dialysis:

• Pay attention to any alarms: If the machine alarms, notify your dialysis nurse or technician immediately.
• Report any unusual symptoms: If you experience any discomfort or unusual symptoms, such as chest pain, shortness of breath, or severe headache, inform your healthcare provider.
• Follow your healthcare provider's instructions: Adhere to your prescribed treatment schedule and dietary and fluid restrictions.

Important Note:

• It is crucial to receive proper training from qualified healthcare professionals on how to understand and interpret the information displayed on your hemodialysis machine, especially if you are conducting home hemodialysis.
• Hemodialysis machines can vary between manufactures, and models. Always follow the training provided by your medical team.
