How often should you reassess a patient on NIPPV?

• A. Reassess every 15 minutes
• B. Reassess only when vital signs worsen
• C. Reassess every 5 minutes and document
• D. Reassess every 60 minutes

Answer: (C)

Regular reassessment is essential when a patient is on NIPPV because clinical status and device performance can change quickly, and timely adjustments are needed to ensure effective ventilation and patient safety. Reassessing every five minutes allows you to monitor oxygenation, ventilation (including work of breathing and CO2 clearance), mask seal and comfort, and hemodynamic stability, and to adjust pressure settings or FiO2 as needed. Documenting these reassessments creates a clear record of how the patient responded, supports handoffs, and guides future decisions about continuing, escalating, or stepping down therapy.

Intervals like every 15 minutes or every 60 minutes can miss rapid changes in tolerance or deterioration, and reassessing only when vital signs worsen delays recognition of problems such as poor seal, excessive leaks, or inadequate ventilation.
