(Greek: imperfect, incomplete)

atelectasis (s); atelectases (pl)
1. An incomplete expansion of the lungs at birth, because of a lack of breathing force.
2. A total or partial collapse of the lungs, because of bronchial obstruction.
3. The absence of gas from all or a part of the lungs, due to a failure of expansion or resorption of gas from the alveoli.
4. A collapsed or airless state of the lung, which may be acute or chronic, and may involve all or part of the lung.

The primary cause of atelectasis is obstruction of the bronchus serving the affected area. In fetal atelectasis the lungs fail to expand normally at birth.

1. Pertaining to or characterized by atelectasis (a partial or total collapse of a lung).

atelesis (s) (noun), ateleses (pl)
Absence of integration or successful completion of an objective or a purpose: Dr. Swift, the psychiatrist, diagnosed Tina as having atelesis or a disintegration and a dissociation of different psychic functions because of her schizophrenic disjunction (separation of something normally joined together) between her inner and outer worlds.

Atelesis has been used by psychiatrists to refer to three major disjunctions that are well known in schizophrenic psychopathology:

  • Disjunction of a person's inner world and environment (autism or phantasies, delusions, hallucinations, etc.).
  • Disjunction of one's ego and the contents of consciousness (splitting or incomplete ego development).
  • Disjunction of someone's experience contents and the elementary forms of mental perception (destruction of conscious and willful focusing on one object or one component at a time).
