Ventilatory Burden vs AHI - Gideon - 09-20-2023 Sharing Quote:Huge Breakthrough in Sleep Apnea Scoring Link to referenced study https://www.mountsinai.org/about/newsroom/2023/mount-sinai-researchers-develop-novel-automated-measure-of-sleep-studies-to-determine-severity-of-obstructive-sleep-apnea?utm_source=MarketingCloud&utm_medium=email&utm_campaign=9-16%20Sleep%20Medicine%20Weekly%20Insider&utm_content=Automated%20measure%20of%20OSA%20severity&utm_term=678654 RE: Ventilatory Burden vs AHI - Jay51 - 09-20-2023 Thank you for posting this Gideon. I read through the article and found a few other statements about it on the internet: "Automated ventilatory burden, which represents the proportion of overnight breaths with <50 percent normalized amplitude, can measure the severity of obstructive sleep apnea (OSA)," "The Mount Sinai Sleep and Circadian Analysis Group developed an automated breath-by-breath measure called ventilatory burden that assesses the proportion of small breaths during a routine sleep study." I am trying to understand this (it seems important to me). It sounds like "tidal volume" is a huge stat to look at during sleep. Not so much respiratory rate per say, but the total # of shallow breaths per night - they theorize that this causes the most damage to the body (cardiovascular, etc.). It would seem to me that with OSA, use EPAP pressure (and possible soft cervical collar for positional apnea) to combat this. With CSA, use a back up rate to ensure at least enough normal # of breaths. (The standard treatments for both OSA and CSA). So according to the measure, a person with a lower respiratory rate, but normal or higher than normal tidal volume would fair better than a person with a higher respiratory rate and lower tidal volume? RE: Ventilatory Burden vs AHI - Gideon - 09-20-2023 Volume varies by the "size" of a person, thus the new term of burden which should account for this. in determining "normal" volumes we take gender and height into consideration. This is also the first time I've seen AI influencing the treatment of sleep apnea. RE: Ventilatory Burden vs AHI - CPAPfriend - 09-21-2023 This is an exciting development. Overdue for an update in diagnostics. I think there were some earlier findings that sort of already said this, but worded it as flow limitation being highly associated with disease severity, but the automated algo with aspirations of refining it with machine learning to optimize its ability to screen for PAP-compliant patients is new and pretty cool. I've always wanted a clean answer as to why some patients respond to PAP and others do not, but none of the top healthcare professionals I've had the chance to have consultation with have provided a satisfying answer. RE: Ventilatory Burden vs AHI - Gideon - 09-21-2023 I think this screams of a (very) long term shift to IVAPS where volume is maintained. That said Fixed or CPAP mode will be needed for individuals intolerant of pressure changes. |
