In this video, you'll learn how to assess aortic stenosis in a patient with reduced flow, despite apparently normal left ventricular function.

In this video, we'll look at the evidence for (and against) the use of NIV in patients with acute asthma exacerbations and consider when NIV might be useful in this cohort.

In this video, we look at how to use CPAP with pulmonary edema patients in order to avoid endotracheal intubation.

In this video, we'll look at how NIV may be used to treat post-extubation respiratory failure or prevent respiratory failure before it occurs.

In this video, from our Blood Gas Analysis Essentials course, you'll learn about the pathophysiologic consequences of a functional state of regional lung ventilation unaccompanied by blood flow—physiological dead space.

In this video, we'll cover the anatomical and physiological factors that determine how well different parts of the lung are ventilated, key equations you need to know that describe this heterogeneity, and how this affects your clinical decision-making.

In this video, you'll learn about the use of colour flow mapping and spectral Doppler-based techniques to locate and visually assess the severity of pulmonary regurgitation.

In this video, we'll review the mechanisms by which NIV can improve ventilation.  

In this video, we'll take a look at the importance of diffusing capacity, as a measure of gas exchange, and consider the clinical factors that affect it.

In this video, you'll learn about the Doppler measurements used to identify the presence of tricuspid valve stenosis.
