COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Patients with pulmonary infection and COVID 19 will have their respiratory management during ICU admission decided in one of two ways
Method 1. Lung ultrasound will be used to make management decisions - this is a non-invasive way of ultrasounding the lungs
One hospital site will use method 1
Three hospitals will use method 2
Both methods are currently standard at the respective hospitals
The comparator treatment will be decided by the attending intensivist. The treatment will be different in every patient. Depending on the results of the auscultation and waveform analysis, a different method of mechanical ventilation or respiratory physiotherapy may be chosen.

Respiratory physiotherapy may be different in each case but will consist of either ventilator hyperinflation, positioning or manual techniques. The senior respiratory physiotherapist will decide the type of physiotherapy treatment delivered based on COVI 19 guidelines.
This will be from admission to ICU to 28 days post hospital discharge

Diagnosis / Prognosis
Comparator / control treatment
Method 2. Management will be decided by using chest x-ray, ventilator readings and auscultation
One hospital site will use method 1
Three hospitals will use method 2. This will be used throughout their admission to ICU.
Both methods are currently standard at the respective hospitals

The comparator treatment will be decided by the assessment above. The treatment will be different in every patient. Depending on the results of the auscultation and waveform analysis, a different method of mechanical ventilation or respiratory physiotherapy may be chosen
This will be from admission to ICU to 28 days post hospital discharge

Statistical methods / analysis
1. A t-test for unmatched groups will compare days on ventilation, ventilator free days, length of stay (hospital and ICU) between St .Vincent’s Hospital and the other three hospitals to investigate whether adding LUS to the assessment criteria improved outcome. A chi-square will compare rates of ventilation between groups, mortality (ICU and 28 day) between the two groups and a Kaplan Meir curve will investigate time until death.

2. Measurements PaO2/FiO2 ratio, static compliance (Cstat), will be compared at the four time points by an ANOVA during all routine physiotherapy management in these patients.

Summary
Brief summary
COVID-19 patients in intensive care will have their ongoing respiratory & ventilator management decided in one of two ways either
1. Using Lung Ultrasound imaging
2 The traditional method of using auscultation, arterial blood gases and ventilator settings such as static compliance
Number of patients ventilated, length of stay (intensive care, hospital (time on ventilator , ventilator free days, mortality (in intensive care and at 28 day ) will be recorded and compared between the two groups. Both methods of management are standard in the intensive care units.
