HAEMODIALYSIS
The sessions can last upto
4, 6, 8, 12 and 24 hours
The process of purifying the blood when a person’s kidneys are not functioning properly. The dysfunction is because of diseases which may be acute or chronic.

Suggested Improvements
Using distinct sounds
for different situations, indicating the error to
the technician better and helping solve the problem faster
The dialysis machine alarm should be different from the ECG monitor, which are currently quite similar
Using backlit displays for certain areas of the machine.
Organizing the blood line in a manner to make the buttons easily accessible. Also to make the patients and the attendants feel at ease.
Using a larger light indicator to indicate the state the machine
is in.
Heparin pump settings once entered cannot be reduced, so a double check system can solve this problem.
