Assessments and exercises of cough strength in critically ill patients: a literature review.

ABSTRACT:

Background and objective

Airway clearance is essential for maintaining patency in critically ill patients and relies on the mucociliary escalator, expiratory flow, and cough strength. A weak cough significantly increases the risk of therapy failure in patients receiving noninvasive ventilation (NIV) or high-flow nasal cannula (HFNC). This review aims to summarize current practices for assessing and exercising cough strength in critically ill patients.

Methods

A comprehensive literature search was conducted in PubMed, Embase, and ScienceDirect using specific keywords related to cough assessment and exercises. A total of 281 articles on cough assessment and 1,407 on cough exercises were identified, with 26 and 73 studies included in the review, respectively.
