Background:Examining the heart and lungs is necessary for critically ill patients, as these individuals may have abnormalities with either or both of these organs. This review systematically determined how the auscultation of the heart and lungs using a wireless stethoscope affected the results. Methods: The research design used was a systematic review following preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Databases were searched using the search terms “auscultation," "critical patients," and "stethoscope wireless” and associated MeSH terms. The abstracts of the selected articles were examined independently by two researchers. A systematic search was conducted through several databases (Scopus, PubMed, JSTOR, and Springer-link), which were published from July 2012 to July 2022 .After reading the full content of the included studies, key themes and concepts were extracted and synthesized. Results: In total 142 articles were screened. Five articles met the inclusion criteria and were analyzed. The analysis revealed that wireless stethoscopes have increased sensitivity with indicators capable of diagnosing abnormal auscultation results in patients who have abnormal aucultation results on the gold standard. Three out of five studies suggested that the auscultation of the heart and lungs by wireless stethoscopes are more sensitive, while two other studies stated that wireless stethoscopes have the same sensitivity as manual acoustic stethoscopes. Conclusion: Based on this systematic review, a wireless stethoscope may be more sensitive than an acoustic one. Nevertheless, due to limited studies, a more well-controlled human study is warranted to be done.

<p><strong><em>Background: </em></strong><em>A stethoscope is an acoustic medical device commonly utilized for listening to internal sounds in the human body. Since its invention, the stethoscope has undergone several transformative improvements, including the introduction of electronic systems in the last two decades. Through the Center of Excellence in the Higher Education of Science and Technology (PUI-PT), Center for Bio Mechanics, Bio Material, Bio Mechatronics, and Bio Signal Processing (CBIOM3S), the Diponegoro University has developed a wireless stethoscope to enable the user to examine the patients quickly without being constrained by tubing, unlike the manual stethoscope. The wireless stethoscope supports health workers in performing their work. This new technology creates various perceptions from its users, one of whom is nurses. </em></p><p><strong><em>Objectives: </em></strong><em>This study aims to provide an overview of nurses' perceptions regarding the usefulness and ease of use of a wireless stethoscope to perform auscultation of the heart and lungs of critically ill patients. </em></p><p><strong><em>Methods: </em></strong><em>The research method employed was a pilot study, and 40 nurses working in the critical care units, including the Intensive Care Unit, High Care Unit, and Stroke Unit in a private hospital in Palembang City, were chosen as respondents for a total sampling technique. </em></p><p><strong><em>Results: </em></strong><em>Nurses' perceptions of the ease and usefulness of a wireless stethoscope were measured using the perceived usefulness and perceived ease of use questionnaires. The nurses' perception of the use of wireless stethoscopes exhibited a mean score of 4.27, while the nurses' perception of the ease of use of wireless stethoscopes showed a mean score of 4.35. Those results indicate that nurses in the critical care units accepted wireless stethoscopes in terms of ease of use and usefulness as a device for performing auscultation of the heart and lungs of critically ill patients. </em></p><p><strong><em>Conclusions: </em></strong><em>Nurses get new technology like a wireless stethoscope because it can work more quickly and is easy to use thereby assisting nurses in conducting cardiac and pulmonary auscultation in critical patients.</em></p>
