What is a pneumogram? A pneumogram is an overnight recording of breathing effort, heart rate, oxygen level, and air flow from the lungs during sleep. It is also called a cardiorespiratory scan, CR scan, pneumocardiogram, or PCG. It can be done in the hospital or at home.
A pneumothorax (pneumo- + thorax; plural pneumothoraces) is an abnormal collection of air or gas in the pleural space that causes an uncoupling of the lung from the chest wall.Like pleural effusion (liquid buildup in that space), pneumothorax may interfere with normal breathing.n a minority of cases, the amount of air in the chest increases markedly when a one-way valve is formed by an area of damaged tissue, leading to a tension pneumothorax.
