| At this point you may attach the patient to either a high pressure or low pressure system. Be familiar with the equipment in your area. A low pressure system (high flow O2 off a standard regulator) can achieve oxygenation but not ventilation. You can get oxygen into the lungs but not with enough pressure to make the chest rise and fall. This method gives you time to attain another form of airway. It will not sustain the patient indefinitely, however, as the patient will retain CO2 and become acidotic. | | | |
