Key inclusion & exclusion criteria	Inclusion criteria: Adult patients (aged 18 years or older) admitted to general medicine unit at the Royal Melbourne Hospital with a cardiopulmonary diagnosis, expected to remain in hospital longer than 24 h. Exclusion criteria: Already admitted longer than 24 h Admitted for social reasons rather than medical Have received an echocardiography within four weeks before admission or a CT chest scan during the admission process before enrolment
Health conditions or problems studied	Heart failure, asthma, COPD, pneumonia, PE, unspecified dyspnea
Intervention	A bedside ultrasound done by a physician trained in POCUS. The ultrasound takes around 20 min to be performed. The quality of the report will be assessed by a second expert who will check the images and videos recorded.
Primary outcome	LOS at the hospital
Secondary outcome	Incidence of new diagnosis and Incidence of changing management. These two outcomes will be assessed only in the interventional group. The treating physician will be asked to fill in a form with the initial diagnosis and plan of management. This form is a checklist describing further investigations (blood test and imaging), consultation to another specialist and medication prescribed (diuretics, antibiotics, etc.). After performing and revealing to them the findings of the bedside ultrasound, the treating physician will be asked to fill a second form that is exactly the same than the first one. The difference between both will be analyzed as “change of management” due to our intervention. Health costs: this outcome will be assessed by the sum of the following three components: (1) cost per day at the hospital; (2) cost of the pathology investigation; (3) cost of the imaging tests.

COPD chronic obstructive pulmonary disease, IMFCU internal medicine focused clinical ultrasound, LOS length of stay, PE pulmonary embolism, POCUS point-of-care ultrasound
