Lung Function Monitoring During Hypoxemia Episodes

"Electrical impedance tomography (EIT) will be used to assess changes in lung aeration prior and during hypoxemia episodes to classify them into four different subtypes.~FE subtype: Defined as HEs preceded by reduction in EELI below the baseline.~Apnea subtype: Defined as HEs not meeting the criteria for FE subtype and preceded by cessation of breathing.~Mixed subtype: Defined as HEs meeting the criteria for both FE and apnea subtypes.~Unclassified: Defined as HEs not categorized into any of the above parameters."
