2020年7月31日 · The maximum WOB was 4.3 (95% CI 3.6 to 5.0), contributed primarily by respiratory rate with a score of 3.6 (95% CI 3.2 to 4.0) and infrequent use of respiratory accessory muscles. All 10 patients survived without need of intubation.

We compared total WOB scores between groups and performance of total WOB for predicting extubation failure with receiver operating characteristic curves. Of 61 subjects enrolled, 9.8% (n = 6) required re-intubation, and 50.8% (n = 31) required any …

2019年10月7日 · The ideal clinical WOB score is a simple and relatively short list of signs of effort of breathing, performing with high absolute interobserver agreement and good discrimination between patients with varying respiratory distress.

2020年11月9日 · Our data suggest that patients with COVID-19 pneumonia can be supported for extended periods using HFNC despite tachypnea provided there is only infrequent use of respiratory accessory muscles, corresponding to a WOB scale ≤ 4, prompting closer assessment for possible intubation when WOB > 4.

Spontaneous breathing frequency (f) and a patient's breathing pattern in general are commonly used to infer the work of breathing (WOB) or respiratory muscle afterload during ventilatory support. 1 A normal or tolerable WOB is inferred when f is approximately 15 to 25 breaths/min for adults 2 and accessory respiratory muscles, such as the ...

Work of breathing (WOB) has been considered to be the best predictive factor in weaning. This study evaluated patient WOB as a predictive measure of weaning and extubation. Blinded, descriptive evaluation of the accuracy of preextubation values of patient WOB in predicting successful extubation.

2024年5月26日 · This review discusses the physiology, measurement, and clinical assessment of WOB, highlighting its utility in the recognition of pneumonia in under-resourced settings, where access to diagnostic imaging may be limited.

2020年12月1日 · Unrecognized WOB increase leads to respiratory muscle fatigue, cessation of respiratory function, and cardiac arrest. We previously developed a WOB Scale for bedside use adding points ...

We compared total WOB scores between groups and performance of total WOB for predicting extubation failure with receiver operating characteristic curves. Of 61 subjects enrolled, 9.8% (n = 6) required re-intubation, and 50.8% (n = 31) required any …
