Acute respiratory distress syndrome

This chapter will review the targets for ultrasound assessment, including biventricular function, extravascular water, and systemic volume assessment. Importantly, it will discuss how to differentiate cardiogenic from non-cardiogenic pulmonary oedema, how to recognize acute cor pulmonale, and when to look for a patent foramen ovale. The advanced section will introduce Doppler-based methods to evaluate right ventricular systolic function and pulmonary arterial systolic pressure, which can both become compromised in acute respiratory distress syndrome.
