ICU Physiology in 1000 Words: Hidden Hemodynamics in Respiratory Mechanics

Jon-Emile S. Kenny MD [@heart_lung] Hemodynamic assessment, by any means, demands a shrewd familiarity with mechanical heart-lung interaction.  The two ventricles communicate in series and in parallel; each ventricle’s pressure-volume characteristics and loading conditions pulsate between systole and diastole.  And around the heart and pericardium lies the respiratory pump – the lungs within the thorax [... read more]

IVC filters’ benefits and risks remain unclear; overused anyway

Inferior vena cava filters (IVCF) are placed to prevent deep venous thromboses (DVT) from traveling to the heart and lungs, causing pulmonary embolism (PE). IVC filters' rationale makes sense, but despite their wide use, the benefits and risks of IVCF remain unclear. With about 50,000 IVC filters placed annually in the U.S., that's a lot of unclarity.

New 2017 GOLD Guidelines for COPD Released

The Global Initiative for Obstructive Lung Disease (GOLD - because GIOLD sounded weird) is an international collaboration of experts in chronic obstructive pulmonary disease (COPD). Every so often the GOLD gang releases another update of their standard-setting GOLD guidelines. (Read PulmCCM's 2014 GOLD guideline review and our COPD Review.) Get the full 2017 GOLD guidelines or the 36 page [... read more]
