Surface electromyography signal processing and evaluation on respiratory muscles of critically ill patients: A systematic review.

Background: Surface Electromyography (sEMG) has been used to monitor respiratory muscle function and contractility in several clinical situations, however there is the lack of standardization for the analysis and processing of the signals.

Objective: To summarize the respiratory muscles most assessed by sEMG in the critical care setting and the assessment procedure details employed on those muscles regarding electrode placement, signal acquisition, and data analysis.

Methods: A systematic review of observational studies was registered on PROSPERO (number CRD42022354469).
