The warm exhaled CO2 is detected by an infrared camera. Rapid jets are exhaled from an unmasked person whereas the warm exhaled air is slow down by a mask and rises due to buoyancy.

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. Lung Injury - Wikimedia Resource Increased interventricular interaction in a patient with constrictive pericarditis. Increased interventricular interaction in a patient with constrictive pericarditis. Transthoracic apical 4 chamber view in a patient with constrictive pericarditis reveals the increased interventricular interaction (with left ventricular volume decrease there is a corresponding increase in right ventricular volume). Pericarditis - Wikimedia Resource Phasic variation in cardiac volumes caused by cardiac tamponade, visualized in transthoracic apical 4 chamber view. Phasic variation in cardiac volumes caused by cardiac tamponade, visualized in transthoracic apical 4 chamber view. The intermittent collapse of the free walls of the right atrium and right ventricle visualized in the transthoracic apical 4 chamber view in a patient with cardiac tamponade. Cardiac Tamponade - Wikimedia Resource Phasic variation in cardiac volumes visualized in transthoracic basal short axis view caused by cardiac tamponade. Phasic variation in cardiac volumes visualized in transthoracic basal short axis view caused by cardiac tamponade. Transthoracic basal short axis view in a patient with cardiac tamponade demonstrates diastolic collapse of the free walls of the right atrium and right ventricle.
