    The following is what is in the dot phrase<\/strong><\/h2>\n\n\n\n

    NOCTURNAL OXIMETRY INTERPRETATION<\/p>\n\n\n\n

    DURATION <\/p>\n\n\n\n

    • Duration of the study is < 5 hours.  Consider repeating the study if results are non-revealing. <\/li>
    • Duration of the study is \u2265 5 hours <\/li><\/ul>\n\n\n\n

      ARTIFACT <\/p>\n\n\n\n

      • There are no significant breaks\/artifact in the saturation waveform. <\/li>
      • There are minor beaks in the saturation waveform consistent with artifact (less than 20% of the total waveform). <\/li>
      • There are major beaks in the saturation waveform consistent with artifact (more than 20% of the total waveform). <\/li><\/ul>\n\n\n\n

        MEAN NOCTURNAL SATURATION <\/p>\n\n\n\n

        • Mean nocturnal saturation is \u2265 92% on room air (within normal limits) <\/li>
        • Mean nocturnal saturation is < 92% on room air.  In the absence of untreated sleep apnea and hypoventilation, low mean saturation may indicate underlying cardiopulmonary disease <\/li>
        • Mean nocturnal saturation > 88% on oxygen therapy.  In the absence of untreated sleep apnea and hypoventilation, requiring oxygen therapy to maintain adequate saturation suggests underlying cardiopulmonary disease. <\/li>
        • Mean nocturnal saturation \u2264 88% on oxygen therapy; may need to increase oxygen therapy.    In the absence of untreated sleep apnea and hypoventilation, requiring oxygen therapy to maintain adequate saturation suggests underlying cardiopulmonary disease. <\/li><\/ul>\n\n\n\n

          Please note that oxygen prescription (based upon Medicare criteria) requires a cumulative time of 5 minutes or more with saturation \u2264 88%. <\/p>\n\n\n\n

          ODI (OXYGEN DESATURATION INDEX) <\/p>\n\n\n\n

          Defined as defined as the mean number of 4% desaturations or greater divided by recording time (hours).<\/p>\n\n\n\n

          There is a decreased sensitivity of the ODI in detecting sleep apnea if the study is performed on supplemental oxygen therapy.<\/p>\n\n\n\n

          • ODI < 10: moderate to severe sleep apnea is less likely but sleep apnea is not excluded and polysomnography (PSG) should be considered if the patient has clinical symptoms of sleep apnea and\/or the waveform is suggestive of sleep apnea <\/li>
          • ODI is between 10 and 30: suggests moderate to severe sleep apnea <\/li>
          • ODI is \u2265 30: highly suggestive of moderate to severe sleep apnea <\/li><\/ul>\n\n\n\n

            SAWTOOTH PATTERN<\/p>\n\n\n\n

            This pattern is characteristic of repeated, cyclical desaturation and increases concern for underlying sleep related breathing disorder such as obstructive sleep apnea.<\/p>\n\n\n\n

            • Is there a sawtooth pattern noted on the oxygen tracing curve? {YES NO:21982}<\/li><\/ul>\n\n\n\n
