INSUFFLATION

Listen to Audio

-blowing of anesthetic gases across a patient's face
-anesthetic technique that avoids direct connection between a breathing circuit and patient's airway
-often useful intially in pediatric patients due to thier resistance of face mask, I.V lines, etc.
-insufflation of high flows (ex. oxygen > 10L/min) may prevent accumulation of carbon dioxide under sterile drapes
-lack of rebreathing on exhaled gases
-uncontrolled ventilation
-unpredictable amounts of inspired gas exits into atmopshere (ex. operating room environment)
-insufflating the trachea with a cathetor, arterial oxygenation can be briefly sustained during small procedures (ex. bronchoscopy)
