Which signal is a sign of dialyzer clotting?

• A. Infiltration
• B. Dark blood in dialyzer
• C. Air detector alarms
• D. Increased venous pressure

Answer: (C)

The signal most associated with dialyzer clotting is the air detector alarm. When the dialyzer begins to clot, blood flow becomes irregular and turbulence can introduce or trap air in the blood circuit. The machine’s air detector is designed to sense any air in the line and will trigger an alarm to stop treatment for patient safety. This immediate alert prompts you to pause, assess the circuit, and replace the dialyzer and tubing as needed. Other signs like infiltration (needle dislodgement), dark blood in the dialyzer (indicating poor flow or clotting), or a rise in venous pressure (indicating increased resistance) can point to problems, but the air detector alarm specifically signals a potentially dangerous air in the circuit and requires urgent action.
