Advantages of Transtracheal O2? 1. Technically Simple 2. 50%-75% reduction in O2 flow 3. Higher PaO2/SaO2 at same flow 4. Modest FIO2 increase over standard cannula
Disadvantages of Transtracheal O2? 1. Performance varies with VT & f 2. Some may be obtrusive 3. Difficult to determine FIO2 4. May interfere with purse lip breathing
