Diagram Of Atelectasis. Pneumonia is usually caused by infection with viruses or bacteria and less commonly by other microorganisms. Shallow monotonous breathing may decrease ventilation to dependent lung regions and may contribute to the development of atelectasis.
Diagram shows display of volume flow and pressure waveforms as seen in the cmv mode. The shaded areas marked with e represent the expiratory phase. Atelectasis lung collapse.
Pneumonia is usually caused by infection with viruses or bacteria and less commonly by other microorganisms.
Several muscles that span several regions of the body such as the thoracic wall itself neck shoulder girdle and abdomen act upon this structure. In the case of atelectasis pulmonary compliance decreases due to a decrease in the volume of the lung and requires higher pressure to inflate the alveoli. Severe retraction of the ear drum may necessitate ear tube surgery or a surgery to rebuild the ear drum tympanoplasty. The commonest of these complications is pulmonary atelectasis though pneumonia is considered to be the main cause of mortality kips 1997.
