[0] Direct connection to common gas outlet (CGO) [1] Readily available in some anesthetizing locations, depending on the anesthesia machine Highly accurate control of gases delivered to the patient [2] Gas supply to anesthesia circuit is interrupted, which is problematic if the circuit is needed for positive pressure ventilation Actual Oxygen concentration is not measured Easy to deliver oxygen > 30% if air and oxygen are mixed Nitrous oxide can mistakenly be delivered [3] 
A connector is needed to adapt the CGO to the delivery system Only enough oxygen flow should be added to the air to get the desired concentration (see Table 2) Important reminder: Do not turn on the nitrous oxide
