A series of video clips showing healthy volunteers coughing. Ten healthy (4 females) volunteers (age 21–28 years) coughing freely, then into their sleeves to demonstrate the effectiveness of this intervention (as recommended by the US CDC: https://www.cdc.gov/flu/protect/covercough.htm ) in limiting the dissemination of the cough aerosol. The first 5 volunteers cough into short sleeves, and the second 5 volunteers cough into long sleeves. It can be seen that in many cases, the cough plume tends to bifurcate into separate streams passing above and below the intervening arm, in some cases with little noticeable loss of momentum. This effectiveness of this intervention is necessarily subject to the degree with which the individual has time to carefully cover the nose and mouth completely with the sleeve, which may not be always possible in various everyday situations.

Additional File 1 A Quick Time movie file demonstrating the high stability of subpleural alveoli during tidal ventilation in the normal lung. Notice the minimal movement with each breath of the alveoli in the two dimensions that can be seen using our in vivo microscopic technique. Each sphere is an individual alveolus.

Additional File 2 A Quick Time movie file demonstrating the change in alveolar mechanics (the dynamic change in alveolar size and shape with tidal ventilation) that occur with acute lung injury. The alveoli in this movie were injured by Tween 20 instillation. Tween 20 deactivates pulmonary surfactant and has been used as model of ARDS for several decades. Notice that alveoli are now very unstable, with some alveoli collapsing totally during expiration and than re-expanding during inhalation.

Transthoracic parasternal long axis view of the left ventricle recorded with normal respiration revealing a decrease in the quality of the echocardiographic image with inspiration.

Transthoracic short axis view recorded during normal respiration. The heart moves medially with inspiration.

Image acquisition during suspended respiration (held end-expiration) in a patient with excessive translational motion of the heart with normal respiration. Transthoracic short axis view. Excessive translational motion can be avoided by acquiring images during held end-expiration. Respiration - Wikimedia Resource Improvement in the quality of the echocardiographic image recorded during held end expiration. Improvement in the quality of the echocardiographic image recorded during held end expiration. Transthoracic parasternal long axis view of the left ventricle recorded during held end expiration showing a significant improvement in the quality of the echocardiographic image. Exhalation - Wikimedia Resource Influence of pulmonary interference on echocardiographic visualization of cardiac structures during normal respiration. Influence of pulmonary interference on echocardiographic visualization of cardiac structures during normal respiration. Transthoracic apical 4 chamber view recorded during normal respiration. During inspiration pulmonary interference does not allow the visualization of cardiac structures.
