the goal of FoCUS is not a full anatomical or functional evaluation&#46; In FoCUS&#44; the clinician performs a simplified but systematic examination to try to obtain key information regarding the physiology of the haemodynamically unstable patient &#40;why does the patient have low blood pressure&#63; Would the patient benefit from administration of fluids&#63; Would it be better to initiate inotropic therapy&#63; &#91;<a class="elsevierStyleCrossRef" href="#fig0010">Fig&#46; 2</a>&#93;&#41; or to detect critical conditions such as cardiac tamponade&#46; The routine FoCUS examination includes the subcostal window &#40;long axis and inferior vena cava&#41;&#44; the apical window and the parasternal window &#40;long axis and short axis&#41;&#46; The key elements of FoCUS are the assessment of the pericardium&#44; the relative size of the chambers&#44; systolic function and volume status&#46; There is evidence that in patients with shock&#44; FoCUS allows the detection of the predominant underlying mechanism &#40;cardiogenic&#44;

a non-invasive&#44; safe&#44; repeatable technique that can be useful in everyday clinical practice if performed by a skilled individual&#44; is already widespread in different fields in paediatrics in several countries&#44; including Spain&#46;<a class="elsevierStyleCrossRefs" href="#bib0225"><span class="elsevierStyleSup">5&#44;7</span></a> Some international guidelines include recommendations for use in paediatrics&#44; for instance for lung ultrasound in critical paediatric patients or for FoCUS&#46;<a class="elsevierStyleCrossRefs" href="#bib0255"><span class="elsevierStyleSup">11&#44;29</span></a> However&#44; with the exception of its use in paediatric emergency care in the United States&#44;<a class="elsevierStyleCrossRefs" href="#bib0225"><span class="elsevierStyleSup">5&#44;23</span></a> there are no clinical guidelines specifying the basic applications of PoCUS in the field of paediatrics or how training on this technique should be delivered and accredited&#46; We believe that this is a key aspect for the adequate introduction of PoCUS&#44; whose application&#44; as is the case of other methods&#44; requires adequate knowledge of the technique and its limitations&#44; and must always fit the clinical situation of the patient&#46; Disregarding these prerequisites could lead to mistakes in clinical decision-making and have a negative impact on patients&#46;<a class="elsevierStyleCrossRef" href="#bib0205"><span class="elsevierStyleSup">1</span></a></p><p id="par0165" class="elsevierStylePara elsevierViewall">An essential aspect that must be underscored is that PoCUS is to be used as an adjunct to the customary clinical evaluation to address specific questions relevant to the management of the patient&#44; and never in place of a comprehensive ultrasound evaluation by the cardiologist or radiologist when one is needed&#46;</p><p id="par0170" class="elsevierStylePara elsevierViewall">Some authors have reported that the learning curve for some ultrasound applications is relatively quick&#44; so that only a few additional ultrasound studies need to be performed after theoretical and practical training for an adequate educational outcome&#46;<a class="elsevierStyleCrossRefs" href="#bib0285"><span class="elsevierStyleSup">17&#44;37</span></a> Another advantage of PoCUS is that several of its applications are used across subspecialities&#44; as is the case of lung ultrasound&#46;</p><p id="par0175" class="elsevierStylePara elsevierViewall">In light of all of the above&#44; we advise the definition of a minimum set of PoCUS applications that ought to be included in the educational curriculum of medical residencies in paediatrics at different levels of care and its different subspecialities&#46; This should be accompanied by the establishment of criteria for the maintenance of these competencies&#44; such as the minimum number of PoCUS studies that must be performed per year&#46;</p><p id="par0180" class="elsevierStylePara elsevierViewall">Another necessary step is for the different paediatric societies in Spain and Europe to establish their positions regarding the use of PoCUS&#44; which would foster the development of specific training programmes and thus promote a more widespread and better integration of this technique in clinical practice&#46;</p><p id="par0185" class="elsevierStylePara elsevierViewall">Last of all&#44; further evidence is required on the use of PoCUS in different fields within paediatrics for the purpose of establishing clear recommendations for its use as well as adequate educational programmes&#46;</p></span><span id="sec0045" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0065">Conflicts of interest</span><p id="par0190" class="elsevierStylePara elsevierViewall">The authors have no conflicts of interest to declare&#46;</p></span></span>"
