Growing evidences are showing the usefulness of lung ultrasound in patients with COVID-19. Sars-CoV-2 has now spread in almost every country in the world. In this study, the investigators share their experience and propose a standardized approach in order to optimize the use of lung ultrasound in covid-19 patients. The investigators focus on equipment, procedure, classification and data-sharing.
Description: Scoring procedures Score 0: The pleura line is continuous, regular. Horizontal artifacts (A-line) are present. These artifacts are generally referred as A-lines. Score 1: The pleura line is indented. Below the indent, vertical areas of white are visible. Score 2: The pleura line is broken. Below the breaking point, small to large consolidated areas (darker areas) appear with associated areas of white below the consolidated area (white lung). Score 3: The scanned area shows dense and largely extended white lung with or without larger consolidations At the end of the procedure, the clinician will write for each area the highest score obtained.Measure: Lung ultrasound grading system for COVID-19 pneumonia Time: At enrollment.
COVID-19 is a rapidly spreading and very contagious disease caused by a novel coronavirus that can lead to respiratory insufficiency. In many patients, the chest radiograph at first presentation be normal, and early low-dose CT-scan is advocated to diagnose viral pneumonia. Lung ultrasound (LUS) has similar diagnostic properties as CT for diagnosing pneumonia. However, it has the advantage that it can be performed at point-of-care, minimizing the need to transfer the patient, reducing the number of health care personnel and equipment that come in contact with the patient and thus potentially decrease the risk of spreading the infection. This study has the objective to examine the accuracy of lung ultrasound in patients with proven COVID-19 pneumonia.

This observational study is designed to assess whether focused lung ultrasound examination can improve the diagnosis of COVID-19 lung disease and/or make an alternative diagnosis at a patient's initial hospital presentation. For patients with confirmed COVID-19 the study will also assess whether surveillance lung ultrasound examination can predict clinical outcome over the course of their hospital admission.

The COVID-19 disease has been subject to numerous publications since its emergence. Almost 20% of people suffering from COVID-19 develop severe to critical symptoms and require hospitalization, often in Intensive Care Unit (ICU). Respiratory failure is the main reason for admission in ICU of these patients. Therapeutic strategies implemented for the management of critically-ill patients may often lead to short-term muscular and functional alterations resulting in ICU-Acquired Weakness (ICUAW). These lead to long-term disabilities expressing trough dependence and quality of life impairment of survivors. The purpose of this study is to assess the quality of life, dependence and survival at one year in patients who survived from COVID-19 in ICU and are admitted in post-ICU setting for difficult weaning purpose. Ancillary studies aim to assess the course of muscle function (atrophy, structural modifications), lung function (loss of aeration) and safety of early mobilization.

ADL scale range from 0 to 6, 6 indicating a better autonomy in activities daily living.Measure: Mean in autonomy score on the Activities Daily Living (ADL) scale Time: At enrollement, 6 months and 1 year

Description: Lung aeration will be assessed using the Lung Ultrasound Score (LUS). Patient is in semi-recumbent position (30°). Lung ultrasound will be performed in 12 thorax area: anterior, lateral and posterior, each area divided in superior and inferior area, for each hemithorax. Lung Ultrasound Score will be recorded using a convex probe with a transverse view. For each thorax area a subscore is calculated: 0 = normal profil; 1 = multiple and well-defined B-lines; 2 = confluent B-lines; 3 = lung consolidation. Sum of this subscores allows calculation of the total score out of 60. Presence of pleural thickening and subpleural consolidations will be also recorded.Measure: Change from baseline in lung ultrasound aeration score Time: Day of enrollement, day 14, day 21, day 28 and day 35 from initial admission in ICU
Description: Diaphragm Ultrasound will be used to assess diaphragm thickness and excursion. Patient is in semi-recumbent position (30°).

Diaphragm excursion will be measured using a subcostal anterior view with convex probe. Excursion measurement is performed in M-mode as the distance between end-inspiration and end-expiration. Three measures of both DTF and excursion will performed and the better will be kept.Measure: Change from baseline in diaphragm ultrasound thickness and excursion Time: Day of enrollement, day 14, day 21, day 28 and day 35 from initial admission in ICU

In light of the ongoing COVID-19 epidemic in Norway, it is paramount to develop and utilize clinical tools for assessing and risk stratifying patients with suspected coronary infection in the emergency departments. Diagnostic use of ultrasound in viral pneumonias, including COVID-19 has proved to be very useful. The use of ultrasound will assist in quick detection of lung pathology compatible with increasing severity of the COVID-19 disease. At the same time, the use of ultrasound diagnostics in the emergency department could improve logistics and reduce potential exposure of the corona virus to other health personnel. The purpose of the study is to assess whether ultrasound findings correlates with physical examination, labs, and other imaging diagnostics in patients with suspected or diagnosed COVID-19 disease, as well as assessing whether ultrasound diagnostics can assist in risk stratification. The project is conducted as a prospective multicenter study where ultrasound diagnostics will be performed on patients with suspected coronary infection in the emergency departments. Data collection takes place as part of the daily clinical evaluation of acute patients in the emergency departments. The project is planned to be completed towards the end of 2025.
