Posted by e-Medical PPT Tuesday, May 12, 2015
Objectives
Indication/contraindication of OLV
Physiology changes of OLV
Selection of the methods for OLV
Management of common problems associated with OLV, especially hypoxemia

One-lung ventilation, OLV, means separation of the two lungs and each lung functioning independently by preparation of the airway
OLV provides:
Protection of healthy lung from infected/bleeding one
Diversion of ventilation from damaged airway or lung
Improved exposure of surgical field
OLV causes:
More manipulation of airway, more damage
Significant physiologic change and easily development of hypoxemia

Indication
Absolute
Isolation of one lung from the other to avoid spillage or contamination
Infection
Massive hemorrhage
Control of the distribution of ventilation
Bronchopleural fistula
Bronchopleural cutaneous fistula
Surgical opening of a major conducting airway
giant unilateral lung cyst or bulla
Tracheobronchial tree disruption
Life-threatening hypoxemia due to unilateral lung disease
Unilateral bronchopulmonary lavage...
