Identification of expired CO 2 to verify correct positioning of an endotracheal tube or laryngeal mask. Inthe ASA American "Standards mandating capnography monitoring devices" of Anesthesiologists Committee on Standards of Care continued its ongoing efforts to refine and update the ASA "Standards for Basic Anesthetic Monitoring," which were first adopted in their original form in and have been modified several times since.
Two substantive amendments that were somewhat different from the Committee's proposals were adopted by the ASA House of Delegates in October and become effective July 1, Members and other interested parties will find the full text of all the monitoring standards on pages of the ASA Directory of Members.
The first and most general point in the "methods" section of the ventilation monitoring standard was modified in such a way as to Standards mandating capnography monitoring devices capnography as a standard for "every patient receiving general anesthesia. Quantitative monitoring of the volume of expired gas is strongly encouraged. This strengthening of ventilation monitoring was intended by the committee as both recognition of the extremely valuable role of capnography and as a logical lead-in to the following standard previously modified to require identification of expired CO 2 to verify correct positioning of an endotracheal tube or laryngeal mask.
Testimony during the proposal and evaluation process raised two main issues.
With the recent potential blurring of the distinction between intravenous sedation and general anesthesia, it was recommended that a clear definition of general anesthesia be developed. Also, concern was expressed about whether capnography will be required in brief, entirely noninvasive procedures such as cardioversion or electroconvulsive therapy during which an anesthesia machine may not even be used.
Further, the committee acknowledged the fact that the "end-tidal CO 2 " numerical value displayed on a monitor during mask anesthesia often may be influenced by gas mixing in the patient's airway and in the mask.
However, the patient-safety orientation, particularly the detection of the failure of ventilation, was seen as key, with the integral role of capnography relating to the basic questions: Is it clearly too high or too low?
