Summary Ultrasound imaging of the lung and associated tissues may play an important role in the management of patients with COVID‐19–associated lung injury. Compared with other monitoring modalities, such as auscultation or radiographic imaging, we argue lung ultrasound has high diagnostic accuracy, is ergonomically favourable and has fewer infection control implications. By informing the initiation, escalation, titration and weaning of respiratory support, lung ultrasound can be integrated into COVID‐19 care pathways for patients with respiratory failure. Given the unprecedented pressure on healthcare services currently, supporting and educating clinicians is a key enabler of the wider implementation of lung ultrasound. This narrative review provides a summary of evidence and clinical guidance for the use and interpretation of lung ultrasound for patients with moderate, severe and critical COVID‐19–associated lung injury. Mechanisms by which the potential lung ultrasound workforce can be deployed are explored, including a pragmatic approach to training, governance, imaging, interpretation of images and implementation of lung ultrasound into routine clinical practice.

Use of TUS by physiotherapists is an emerging area in both diaphragm and lung diagnostics. A wide range of patient populations may benefit from physiotherapists using TUS. Papers in this review are heterogeneous making any generalisability difficult but does show its potential for varied uses. TUS is an innovative skill in the hands of physiotherapists, but more research is needed.

IntroductionIt is well-recognised that the detection of rib fractures is unreliable using chest radiograph. The aim of this systematic review was to investigate whether the use of lung ultrasound is superior in accuracy to chest radiography, in the diagnosis of rib fractures following blunt chest wall trauma.MethodsThe search filter was used for international online electronic databases including MEDLINE, EMBASE, Cochrane and ScienceDirect, with no imposed time or language limitations. Grey literature was searched. Two review authors completed study selection, data extraction and data synthesis/analysis process. Quality assessment using the Quality Assessment of Diagnostic Accuracy Studies Tool (QUADAS-2) was completed.Results13 studies were included. Overall, study results demonstrated that the use of lung ultrasound in the diagnosis of rib fractures in blunt chest wall trauma patients appears superior compared with chest radiograph. All studies were small, single centre and considered to be at risk of bias on quality assessment. Meta-analysis was not possible due to high levels of heterogeneity, lack of appropriate reference standard and poor study quality.DiscussionThe results demonstrate that lung ultrasound may be superior to chest radiography, but the low quality of the studies means that no definitive statement can be made.

Introduction Physiotherapists are learning to perform diagnostic thoracic ultrasound but it is currently unknown how they are learning, how they are using thoracic ultrasound in their practice, or any factors affecting the implementation of thoracic ultrasound into practice. The aim of this survey was to explore the use of thoracic ultrasound by physiotherapists. This information could be used to aid training and implementation strategies to assist physiotherapists to integrate thoracic ultrasound safely into their practice. Methods A questionnaire comprising of open/closed questions was distributed to respiratory physiotherapist. Distribution was at three national study days and via a specialist newsletter containing a link to a SurveyMonkey™ questionnaire. Results A total of 133 questionnaires were returned with 31 reported that they used thoracic ultrasound imaging and 101 reporting they did not. The most common roles of thoracic ultrasound in practice were to: enhance the ability to differentially diagnose respiratory pathologies, aid respiratory assessment and support clinical reasoning. Of the 133 respondents, 58 reported that they had undertaken training in thoracic ultrasound imaging and 75 had not. The most common factors identified regarding thoracic ultrasound implementation were team support, ultrasound machine availability/cost, time pressures and mentor availability. Discussion This survey has provided an understanding of thoracic ultrasound practice amongst respiratory physiotherapists in the UK. The survey results demonstrated the barriers that inhibit current practice and highlighted the importance of mentor support. There was a good understanding by all respondents regarding the clinical application of thoracic ultrasound. These findings are being used to develop professional guidance and ensure safe practice of thoracic ultrasound.
