Which of the following is an example of healthcare IT *physical* infrastructure?

Biomedical devices represent an example of healthcare IT physical infrastructure because they involve tangible, physical equipment used in medical settings. These devices include a variety of instruments such as ventilators, monitoring devices, and imaging systems, all of which play a critical role in patient care and medical diagnostics.

In a healthcare setting, physical infrastructure refers to the essential hardware or equipment required to support health IT functions. Biomedical devices fall squarely into this category, as they are the actual machines that healthcare professionals utilize in the delivery of care.

The other options, while important components of healthcare informatics, do not embody physical infrastructure. Clinical protocols are guidelines for treatment and patient care; electronic communication protocols define the standards for data communication but do not represent physical assets; and cloud storage is a virtual solution for data management rather than a physical entity.
