“…Similar results were found in children with respiratory diseases (-0.08<kappa<0.86) [23][24][25]. Direct comparisons between conventional and digital stethoscopes showed that, although digital stethoscopes have a better sound quality [26], the performance of health professionals to detect respiratory sounds is not enhanced by its use [27].…”

Respiratory physiotherapy is part of the routine management of patients with cystic fibrosis. It normally consists of airway clearance techniques and exercise training. The evidence of such interventions has been questioned. Nevertheless, the lack of evidence should not be interpreted as lack of benefit. Instead, attention to methodological issues, such as the selection of the outcome measures, is needed, as they may hamper the establishment of the effectiveness of respiratory physiotherapy techniques. Hence, this chapter presents and discusses the strengths and weaknesses of conventional and emerging outcome measures possibly to be used i in clinical practice before, during and after each session of respiratory physiotherapy to monitor its effectiveness ii before and after the respiratory physiotherapy treatment i.e., normally characterised by weeks of intervention and iii in applied research in respiratory physiotherapy used in the management for cystic fibrosis. " comprehensive overview of the available outcome measures is provided, with particular emphasis on their strengths and limitations that should be recognised when interpreting the results.

“…It is likely, however, that electronic capture of carotid sounds is more reliable based on the greater prevalence of bruits in FDS2 versus FDS1 of 6.1% versus 4.5% 3 and in other studies directly comparing the two methods. 11,12 The present study suggests that electronic auscultation is more accurate than a conventional acoustic stethoscope for the detection of carotid bruits in patients with diabetes, while offering the convenience of later interpretation if a skilled operator is not available when the patient is assessed. The presence of a bruit identified in this way should prompt (1) intensified cardiovascular risk factor management and (2) consideration of ultrasonography and perhaps other imaging with a view to revascularization, depending on symptoms and factors such as age and comorbidities.…”

“…4 The higher sensitivity and lower specificity found in the present study could be due to several factors. First, the better acoustic quality obtained using the electronic stethoscope 11,12 may have meant that more bruits were detected. This includes softer bruits both associated with reduced flow in severely stenosed vessels, 24 thus increasing sensitivity, and as a manifestation of low-grade stenoses or vascular tortuosity, which would attenuate specificity and positive predictive value.…”

“…These digital recordings are of better quality than those obtained using acoustic stethoscopes. 11,12 This technology has been applied successfully in clinically challenging situations such as in aviation medicine, 12 prisons, 13 and remote clinics. 14 The sensitivity and specificity of carotid bruits ascertained by electronic auscultation for ultrasonographically identified carotid stenosis and increased CIMT have not been examined previously.…”

Electronic recording of carotid sounds for later interpretation is convenient and reliable. Most patients with stenoses had an overlying bruit. Most bruits were false positives, but ultrasonography is justified to document extent of disease; CIMT measurement will identify increased vascular risk in most of these patients. The absence of a bruit was rarely a false-negative finding, suggesting that these patients can usually be reassured that they do not have hemodynamically important stenosis.

“…The electronic stethoscope has been found to be useful in the noisy environment of military flight medicine, where physicians contend with jet engines to listen to lung sounds. When using an electronic stethoscope aboard a Boeing C135 military transport airplane, physicians rated it better for hearing heart and lung sounds 12. A study by the same group using a “Sim-Man” mannequin in an environment simulating that aboard a C135 demonstrated better performance on pulmonary auscultation by a sample of four intensivists and a nurse anaesthetist when using an electronic stethoscope 13.…”

BackgroundElectronic stethoscopes are becoming more common in clinical practice. They may improve the accuracy and efficiency of pulmonary auscultation, but the data to support their benefit are limited.ObjectiveTo determine how auscultation with an electronic stethoscope may affect clinical decision making.MethodsAn online module consisting of six fictional ambulatory cases was developed. Each case included a brief history and lung sounds recorded with an analogue and electronic stethoscope. Internal medicine resident participants were randomly selected to hear either the analogue or electronic lung sounds. Numbers of correct answers, time spent on each case and numbers of times the recordings were played were compared between the groups who heard each mode of auscultation, with a p value of less than 0.05 indicating statistical significance.Results61 internal medicine residents completed at least one case, and 41 residents completed all six cases. There were no significant differences in overall scores between participants who heard analogue and electronic lung sounds (3.14±0.10 out of 6 correct for analogue, 3.20±0.10 out of 6 for electronic, p=0.74). There were no significant differences in performance for any of the six cases (p=0.78), time spent on the cases (p=0.67) or numbers of times the recordings were played (p=0.85).ConclusionWhen lung sounds were amplified with an electronic stethoscope, we did not detect an effect on performance, time spent on the cases or numbers of times participants listened to the recordings.
