Pneumonia caused by fluid accumulating in the lungs of a bedridden person with a weak heart.
Pneumonia occurring in elderly or bed-ridden patients who remain constantly in the same position. Ventilation is greatest in dependent areas; remaining in one position causes hypoventilation in many areas, causing alveolar collapse (atelectasis) and creating a pulmonary environment that supports the growth of bacteria or other organisms. Development of this condition is prevented by having the patient change positions and take deep breaths to inflate peripheral alveoli.
Accumulation and blockage in the lower regions of the lungs, commonly observed in elderly patients who are bedridden and remain immobile for extended periods.
