Q: What are the two types of postobstructive pulmonary edema?
Answer: Type I and Type II
- Type I is due to the forceful inspiratory effort in acute airway obstruction,
- Type II is after relief of chronic partial airway obstruction (mostly surgical intervention)
Common Type I examples encountered in ICU/emergent setting is
- Postextubation laryngospasm
- Choking/foreign body/Strangulation
- Endotracheal tube obstruction
- Laryngeal tumor/Goitre
- Mononucleosis
- Postoperative vocal cord paralysis
- Near drowning
- Intraoperative direct suctioning of endotracheal tube adapter
Some examples of Type II are
- Post-tonsillectomy/adenoidectomy
- Post-removal of upper airway tumor
- Hypertrophic redundant uvula
