Editor's Notes

1. Reservoirs are: Nadopharynx for Canulla, Oropharynx for Nasal Catheter and The mask itself for simple mask Nasal Canulla communication and access to oral intake. FiO2 increases by 3% to 4% with each 1 L increment in flow Simple Mask flow rate of a simple mask should never be <5 L/min; below this level, carbon dioxide rebreathing may occur, along with an increased resistance to inspiration are also more uncomfortable, making eating and communicating challenging. Because they cover the mouth, aspiration is a risk with any mask. Reservoir Masks has an attached reservoir of 600 to 800 mL, resting below the patient’s chin flow between 8 and 15 L/min, which keeps the reservoir bag at least half full. In Partial rebreather patient exhales approximately the first one-third of the expired tidal volume into the reservoir. In Non rebreather oxygen flow should be set high enough to prevent deflation of the reservoir bag—usually about 15 L/min 
2. HFNC- Has PEEP of 4cm H20. Must be cautious about Barotrauma
3. ASV: Adaptive servo-ventilation
