When should you check pulse, motor, and sensory (PMS) in patients?

Checking pulse, motor, and sensory (PMS) function is essential in assessing a patient's neurological and vascular status, particularly when they may have sustained an injury that could compromise these areas. The correct practice is to conduct this assessment before and after any splinting or immobilization, such as backboarding.

Performing PMS checks before splinting ensures that you have a baseline understanding of the patient's neurological and vascular integrity. This can help identify any changes or complications resulting from the injury itself, or from the intervention being applied. After splinting or backboarding, performing another PMS check is crucial to ensure that the intervention has not unintentionally impaired blood flow or nerve function.

This comprehensive approach helps in monitoring for any deterioration in status, which is especially critical in cases of suspected fractures or spinal injuries where manipulation can lead to further complications. By regularly assessing these factors, paramedics can make informed decisions about the urgency of transport and the care needed in the hospital.
