Oxygen for respiratory tract infection?
Posted: Tue Nov 24, 2015 4:43 pm
My child is CNVS-dependent and has a respiratory tract infection and his O2 sat is in the 80s. The doctors want to give oxygen. What should I do?

Supplemental oxygen and/or sedative medications can “turn off” breathing, cause the CO2 to soar and cause one to stop breathing entirely, and it makes the oximeter useless as a gauge of ventilation, airway secretions, and lung disease (e.g. pneumonia) since each of these can cause the O2 sat to decrease below 95%. Never use supplemental O2 in the home instead of maintaining normal O2 sat by providing noninvasive ventilatory support (NVS) and MIE as needed to clear airway secretions. If the baseline O2 sat stays below 95% despite effective use of CNVS and/or MIE, then the person needs to be hospitalized.
Emergency personnel will also want to administer O2, which can cause one to stop breathing. O2 should not be administered unless there is someone present who can intubate the patient. O2 can be administered while one is intubated because lung ventilation is controlled by the machine in this situation, but it should be discontinued and the baseline O2 sat normal (95% or greater) on room air (without supplemental O2) for 24 hours before one is extubated.
