What is an essential parameter that should be monitored during dialysis treatment?

Monitoring blood pressure and heart rate during dialysis treatment is crucial due to the significant hemodynamic changes that can occur. Dialysis can lead to shifts in fluid balance and changes in blood volume, which may cause hypertension or hypotension, and can affect the patient’s cardiovascular stability.

Abnormalities in blood pressure can indicate complications such as fluid overload or the body’s response to dialysis, potentially leading to symptoms of dizziness, cramping, or even more severe complications if left unmonitored. Heart rate is also important to assess as it can reveal the patient’s overall cardiovascular response during treatment. By keeping a close eye on these vital signs, healthcare providers can act quickly to address any issues and ensure patient safety throughout the dialysis session.

Other options, while relevant in the context of patient care, do not provide immediate and critical information regarding the patient's physiological status during the treatment process.
