What are the five P’s of a neurovascular assessment?
This article discusses the process for monitoring a client’s neurovascular status. Assessment of neurovascular status is monitoring the 5 P’s: pain, pallor, pulse, paresthesia, and paralysis. A brief description of compartment syndrome is presented to emphasize the importance of neurovascular assessments.
How long does acute limb ischemia last?
