What is one characteristic feature of the disposable portable system NPWT?

  1. Requires multiple healthcare professionals for application

  2. Utilizes negative pressure for shallow wounds

  3. Involves complex machinery

  4. Only applicable for chronic wounds

The correct answer is: Utilizes negative pressure for shallow wounds

The characteristic feature of the disposable portable system for negative pressure wound therapy (NPWT) is that it utilizes negative pressure specifically for promoting healing in shallow wounds. This system applies negative pressure directly to the wound bed, which aids in the removal of exudate and infectious materials, reduces edema, and promotes angiogenesis. This mechanism makes the system versatile, as it can be effective for various types of wounds, including shallow ones, by creating a conducive healing environment. The design of disposable portable NPWT systems allows for ease of use and patient mobility, making them ideal for outpatient settings. While utilizing negative pressure is essential to the function of NPWT, the other choices describe elements that are not aligned with the characteristics of the portable system. For instance, NPWT does not necessarily require multiple healthcare professionals for application; trained personnel can typically manage it independently. Additionally, these portable systems are designed to be user-friendly, avoiding the complexities often seen in traditional NPWT machines. Lastly, portable NPWT is not limited to chronic wounds, as it can be used on various wound types, including acute wounds, underscoring its versatility in clinical practice.
