Intra-treatment Monitoring and Vital Signs
Key Takeaways
- Trend vital signs against the pre-treatment baseline and the ordered prescription.
- Observe the patient, access, bloodlines, pressures, alarms, and ultrafiltration throughout treatment.
- Report abnormal findings promptly instead of waiting for the next routine check.
- Documentation should reflect what was assessed, what changed, who was notified, and the response.
Monitoring During Treatment
Intra-treatment monitoring is active surveillance, not just recording numbers. Compare each vital sign, machine reading, and patient comment with the pre-treatment baseline, the dialysis prescription, and recent trends. A normal-looking single value can still matter if it is moving quickly in the wrong direction.
What to Watch
| Area | Examples | Why It Matters |
|---|---|---|
| Patient | Blood pressure, pulse, respirations, pain, nausea, cramps, dizziness, mental status | Early signs may appear before a severe event. |
| Access | Needle position, bleeding, swelling, infiltration, securement | Access problems can cause blood loss or poor treatment. |
| Circuit | Arterial and venous pressures, air detector, clamps, dialyzer appearance | Pressure changes may signal needle, line, or clotting issues. |
| Prescription | Blood flow rate, dialysate settings, UF goal, UF rate, treatment time | The machine should match the ordered treatment. |
Exam-Safe Monitoring Habits
- Look at the patient before trusting the machine display.
- Recheck unexpected readings with proper technique.
- Keep bloodlines visible and connections secure.
- Ask focused questions when the patient reports feeling different.
- Notify the RN or qualified staff for abnormal findings per protocol.
Documentation should be timely, factual, and complete. Record vital signs, machine parameters, symptoms, interventions done within role, staff notified, and patient response. Do not chart an assessment that was not performed, and do not delay reporting because a value has been entered in the record.
During routine monitoring, a patient's blood pressure drops from 148/82 pre-treatment to 104/60, and the patient says they feel lightheaded. What is the best first technician action?
