How long should a patient wear a NPWT system?

• A. At least 22 hours a day to aid in wound healing
• B. 8 hours per day
• C. 12 hours per day
• D. 24 hours per day

Answer: (A)

Negative Pressure Wound Therapy works best when the negative pressure is applied almost all the time. Keeping the NPWT system on for the majority of the day ensures continuous drainage, reduced edema, increased perfusion, and stimulation of granulation tissue. The recommended minimum is to wear it for at least 22 hours in a 24-hour period. Shorter wear times—like eight or twelve hours—would interrupt the therapeutic window and slow healing. While a 24-hour schedule is possible, the guideline emphasizes a minimum of 22 hours to allow brief, necessary pauses for dressing changes and care while still maintaining the wound under consistent suction.
