Ventilation in anesthetized animals
Accumulation of CO₂, causing respiratory acidosis = Hypercarbia Reduced oxygen uptake, risking tissue hypoxia = Hypoxemia Partial collapse of alveoli due to insufficient lung expansion = Atelectasis
- = -
Manual ventilation
Manual ventilation
Performed every 2–5 minutes to expand alveoli and prevent atelectasis. = Periodic ! = ! Required for cases of preexisting heart or lung disease. = Intermittent mandatory @ = @
