Impact of ultrasound settings on lung vertical artefacts: an observational stud...
Leote, João; Gonçalves, Andreia; Fonseca, Júlia; Loução, Ricardo; Dias, Maria Hermínia Monteiro Brites; Ribeiro, Maria Inês; Meireles, RicardoThe number of vertical artefacts (VAs) in lung ultrasound (LUS) impacts patients' clinical management. This study aimed to demonstrate the influence of ultrasound settings on the number of VAs in patients under invasive mechanical ventilation (IMV). Methods: Patients under IMV were recruited for LUS, including three breathing cycles with a motionless curvilinear probe on the thoracic region with the most VAs. T...
Diaphragm ultrasound for muscle strength assessment: a systematic literature re...
Leote, João; Monteiro, Margarida; Rocha, Cláudia; Rodrigues, Carolina; Pereira, Marco; Antunes, Maria Luz; Dias, Maria Hermínia Monteiro BritesObjective: To assess if diaphragmatic ultrasound (DU) reflects diaphragmatic muscle strength when compared to respiratory tests and neurophysiological studies. Methods: A systematic literature review was conducted on adults undergoing DU, compared to any respiratory or neurophysiological technique. The search strategy was applied in PubMed, Scopus, and Web of Science, and the analysis was conducted using the PR...
To B or not to B-lines [editorial]
Gonzalez, Filipe André; Bacariza, Jacobo; Leote, João; EchoCrit GroupWith great interest, we have read the paper from Boero et al. titled “Lung Ultrasound among Expert Operators: Scoring and Inter-rater Reliability Analysis (LESSON study), a secondary COWS study analysis from the ITALUS group”, which provides a focused evaluation of lung ultrasound (LUS). The author’s analysis reflects the increasing use of LUS as a valuable diagnostic and monitoring tool for assessing pulmonary...
Impact of ultrasound settings on B-lines: observational study in IMV patients
Gonçalves, A.; Fonseca, J.; Leote, João; Loução, R.; Dias, Hermínia Brites; Ribeiro, I.; Meireles, R.; Varudo, R.; Bacariza, J.; Gonzalez, F.Currently, there are no lung ultrasound (LUS) established guidelines for the identification of B-lines. This study aimed to evaluate if the US settings have an impact on the number of B-lines in invasively ventilated patients.
Contributo da ultrassonografia pulmonar no diagnóstico de pneumotórax
Ramos, Andreia; Barros, Joana; Almeida, Márcia; Leote, João; Dias, Hermínia BritesA ultrassonografia pulmonar tem vindo a ganhar destaque no diagnóstico de patologias da pleura, nomeadamente no pneumotórax, onde apresenta vantagens em relação às duas técnicas gold standard, a radiografia do tórax e a tomografia computorizada (TC). É uma técnica que tem obtido cada vez mais visibilidade, e que não é de aplicação específica de um grupo profissional, pelo que pode vir a ser uma futura competênc...
Machine learning for the real-time assessment of left ventricular ejection frac...
Varudo, Rita; Gonzalez, Filipe; Leote, João; Martins, Cristina; Bacariza, Jacobo; Fernandes, Antero; Michard, FredericBackground: Machine learning algorithms have recently been developed to enable the automatic and real-time echocardiographic assessment of left ventricular ejection fraction (LVEF) and have not been evaluated in critically ill patients. Methods: Real-time LVEF was prospectively measured in 95 ICU patients with a machine learning algorithm installed on a cart-based ultrasound system. Real-time measurements taken...
Automation of sub-aortic velocity time integral measurements by transthoracic e...
Gonzalez, Filipe; Varudo, Rita; Leote, João; Martins, Cristina; Bacariza, Jacobo; Fernandes, Antero; Michard, FredericPoint-of-care ultrasound techniques are increasingly used for the bedside assessment of cardiac function and haemodynamics in critically ill patients. The sub-aortic or left ventricular outflow tract velocity time integral (VTI) can be measured using pulsed-Doppler ultrasonography from a transthoracic apical 5-chamber view. Quantifying VTI is useful to discriminate between vasoplegic states (hypotension with no...
