Echocardiography in critically ill patients has become essential in the evaluation of patients in different settings, such as the hospital. However, unlike for other matters related to the care of these patients, there are still no recommendations from national medical societies on the subject. The objective of this document was to organize and make available expert consensus opinions that may help to better incorporate echocardiography in the evaluation of critically ill patients. Thus, the Associação de Medicina Intensiva Brasileira, the Associação Brasileira de Medicina de Emergência, and the Sociedade Brasileira de Medicina Hospitalar formed a group of 17 physicians to formulate questions relevant to the topic and discuss the possibility of consensus for each of them. All questions were prepared using a five-point Likert scale. Consensus was defined a priori as at least 80% of the responses between one and two or between four and five. The consideration of the issues involved two rounds of voting and debate among all participants. The 27 questions prepared make up the present document and are divided into 4 major assessment areas: left ventricular function, right ventricular function, diagnosis of shock, and hemodynamics. At the end of the process, there were 17 positive (agreement) and 3 negative (disagreement) consensuses; another 7 questions remained without consensus. Although areas of uncertainty persist, this document brings together consensus opinions on several issues related to echocardiography in critically ill patients and may enhance its development in the national scenario.

The use of echocardiography by physicians who are not echocardiographers has become common throughout the world across highly diverse settings where the care of acutely ill patients is provided. Echocardiographic evaluation performed in a point-of-care manner can provide relevant information regarding the mechanism of causes of shock, for example, increasing the rates of correct diagnosis and allowing for faster informed decision-making than through evaluation methods. Considering that the accurate diagnosis of life-threatening situations is essential for professionals working with acutely ill patients, several international associations recommend that physicians responsible for critically ill patients acquire and develop the ability to perform bedside ultrasound examinations, including echocardiographic examinations. However, there is no consensus in the literature regarding which specific applications should be included in the list of skills for nonechocardiographer physicians. Taking into account the multiplicity of applications of echocardiography in different scenarios related to acutely ill patients; the differences in the published protocols, with regard to both the teaching methodology and competence verification; and the heterogeneity of training among highly diverse specialties responsible for their care at different levels, this consensus document aimed to reflect the position of representatives of related Brazilian medical societies on the subject and may thus serve as a starting point both for standardization among different specialties and for the transmission of knowledge and verification of the corresponding competencies.
