摘要
An apparatus and method for titrating the oxygen content delivered to a patient via an open delivery system and reduce fire risk. The apparatus may include a nasal cannula or face mask and an anesthesia machine having an air flowmeter. The cannula may be in fluid connection with one or more gas outlets on the anesthesia machine. The cannula may provide a user-adjustable reduced O2 content gas flow to the patient. By providing an O2 gas mixture having a lower concentration of O2, the present invention significantly mitigates the risk of surgical fires. The apparatus may also include an anesthesia machine having an electronic flowmeter, either alone or in conjunction with the cannula, for maintaining oxygen saturation at a selected level. The apparatus may also include an anesthesia machine having an additional operating mode for use with an open delivery system.
