Filter by:The assessment of respiratory muscle function is critical within both clinical and research settings. Tools for the assessment of respiratory muscle function are especially useful in diagnosing, phenotyping, understanding pathophysiology, and assessing treatment responses in patients with respiratory symptoms, including critically hill patients and patients with respiratory and/or neuromuscular diseases. Respiratory muscle function is most commonly assessed using flow (i.e. spirometry) and pressure measurements during spontaneous ventilation, voluntary respiratory efforts, or artificially evoked responses using magnetic or electrical stimulation. Some of these approaches may be limited within patients suffering from neuromuscular diseases. The study hypothesis is the 18F-FDG PET technology, heavily used for clinical oncology purposes (diagnostic, staging, response to treatment, prognosis), could be an interesting alternative to invasive measurement of the respiratory muscle activity. In addition, it may contribute to further validate metrics based on multiparametric ultrasound imaging.
Ultrasonographic evaluation of respiratory muscle thickness in stroke patients, determination of its correlation with pulmonary function test (PFT) , and the first evaluation method to determine respiratory rehabilitation goals and to use it in the follow-up of the effectiveness of the treatment.
Currently, there are few studies that have been established that consist of a variety of established and coherent approaches that sought to profile the determinants of recovery, nor used interrogative procedures to understand lasting physical impairment. In this context, measurements obtained from an assessment of cardio-respiratory responses to physiological stress could provide an important insight regarding the integrity of the pulmonary-vascular interface and characterisation of any impairment or abnormal cardio-respiratory function [4]. Indeed, current approaches are being developed to support patients using previous knowledge from other acute respiratory infections (e.g. Acute Respiratory Distress Syndrome; ARDS and Middle Eastern Respiratory Syndrome; MERS), approaches that do not consider the novel challenges presented by COVID-19. The knowledge obtained from the proposed research plan will inform the development of COVID-19 specific rehabilitation and clinical management guidelines which can be implemented globally to increase patient wellbeing, physical capacity, and functional status which will be directly related national and international health and wellbeing, economical and societal impacts.
Diaphragm ultrasound non-invasively explores the diaphragm function and it can be useful in several clinical situations. Diaphragm ultrasound is able to evaluate the cranio-caudal displacement of the diaphragm and its thickening fraction at the end of inspiration, in relation to the end-expiratory value. While several studies have been conducted in the evaluation of educational programmes for echocardiography, to date data lack regarding this aspect in diaphragm ultrasonographic assessment. Based on the experience gained in some specialization schools in Anaesthesia and Intensive Care, the investigators hypothesize that the participation in a two-hour course, including a theoretical part and a practical training, allows to acquire the appropriate theoretical and practical skills necessary to correctly perform the measurement of the diaphragm excursion and thickening fraction, compared to the theoretical lesson only, followed by a brief explanation by an expert tutor, on the practical use of the ultrasound. The investigators hypothesized that the association of the theoretical part and of the practical training is able to obtain: 1. Passing the theoretical test with at least 70% of the correct answers; 2. The correct identification of the areas where the probe is affixed; 3. The appropriate measure of Diaphragmatic thickening and displacement.
The investigators seek to understand how reflexes from the breathing muscles influence blood pressure during exercise. Furthermore, the investigators are determining if increasing breathing muscle strength (via inspiratory muscle training) influences the respiratory muscle contribution to blood pressure during exercise.
