Filter by:The goal of this observational study is to learn about the function of lung and diaphragm ultrasound during weaning from mechanical ventilation in COVID-19 patients. The aim of this study was that the lung ultrasound score and diaphragm muscle mobility could be a potential predictive factor of weaning success.
Evaluation of respiratory function is considered a crucial component in the assessment of patients with a wide range of respiratory diseases. Spirometry is considered a common method of measuring pulmonary function. Recently, Transthoracic ultrasound yields important diagnostic information within minutes. Respiratory muscle ultrasound is used to evaluate the anatomy and function of the respiratory system.
Aim: To evaluate real-time ultrasound in the evaluation of diaphragmatic thickening, thickening fraction and or excursion to predict extubation outcomes. The investigators aimed to compare these parameters with other traditional weaning measures.
In this study, a single‐center, prospective, observational study was adopted to set the cut-off values of diaphragmatic ultrasound results and arterial blood gas results,with the choice of non-invasive oxygen therapy as the gold standard,so as to evaluate the diagnostic value of diaphragmatic ultrasound in the selection of non-invasive oxygen therapy.
The Rapid Shallow Breathing Index (RSBI) is the ratio between respiratory rate (RR) and tidal volume (VT). It is routinely used to predict mechanical ventilation weaning outcome in ICU patients. However RSBI doesn't reflect the muscular contribution of diaphragm or accessory muscles in generating tidal volume. Actually, diaphragmatic dysfunction can even delay weaning process, because accessory muscles are more fatigable than the diaphragm. Hence, the investigators hypothesized that diaphragmatic displacement (DD) could be associated with RSBI in a new index named Rapid Shallow Diaphragmatic Index (RSDI) such as: RSDI = RSBI/DD. The aim of this study is to compare the ability of the RSDI versus the traditional RSBI to predict weaning success in ready-to-wean patients.
This study evaluates the correlation between maximum inspiratory pressure (Pi max) and the diaphragm maximum inspiratory excursion measured with ultrasound during the weaning from invasive mechanical ventilation.
