The increasing integration of digital technologies in the healthcare field has raised questions about the accuracy of these devices. Therefore, this study aims to support, through scientific evidence, its use in critical environments. The main objective of the article was to evaluate the accuracy and reliability of digital blood pressure monitors used to monitor the blood pressure of patients in critical health units. To carry out the analysis, a qualitative approach was adopted that involved the review and analysis of a set of ten previously published studies, which were selected from highly reliable academic and medical sources. The choice of a qualitative approach was based on the need to carry out a thorough and detailed examination of the studies available in the scientific literature, with the purpose of identifying patterns, trends and limitations in the use of digital blood pressure monitors in critical healthcare settings.During the review and analysis process of the ten selected studies, special attention was given to several key aspects. Firstly, the methodology used in each of the studies was evaluated, paying particular attention to their methodological quality. Likewise, the measurement techniques used, the sample size, the population studied and the conditions were examined. environments in which the measurements were carried out. The results obtained from this analysis revealed interesting trends regarding the accuracy and reliability of digital blood pressure monitors in blood pressure monitoring. Overall, digital devices demonstrated satisfactory accuracy and reliability in blood pressure measurement. However, it is important to highlight that some limitations and variations in the results are identified, which can be attributed to various factors. One of the factors identified as influencing the precision of the measurements was the obesity of the patients, since in these cases digital blood pressure monitors can provide less precise measurements. Additionally, the position of the arm during measurement can also influence the results, underscoring the importance of standardizing position to obtain consistent and reliable measurements.On the other hand, poor quality cuffs can affect the accuracy of blood pressure measurements. Therefore, the use of high-quality cuffs in clinical practice is strongly recommended. Finally, the environmental conditions under which measurements are made can influence the results. Factors such as temperature and humidity can affect the function of digital blood pressure monitors, highlighting the importance of controlling these conditions for accurate and reliable measurements. In conclusion, digital blood pressure monitors have emerged as valuable tools in monitoring blood pressure in critical health units. However, its successful implementation requires careful evaluation of the circumstances and precise calibration.
