This is an observational, proof-of-concept, feasibility study that aims to evaluate the feasibility of a monitoring system that integrates clinical data, high-resolution waveforms from the bedside monitor, regional oxygenation (via cerebral and splanchnic near-infrared spectroscopy), and regional ventilation (via electrical impedance tomography) from 20 extremely low birth weight infants at high-risk of reintubation.
The primary aim of this proof-of-concept study is to evaluate the feasibility and acceptance of a monitoring system that integrates clinical data and biomedical signals from multiple modalities in a cohort of extremely preterm infants at high-risk of clinical instability on non-invasive respiratory support.
Secondary aims will be to longitudinally describe peripheral oxygen saturation, cerebral oxygen saturation, splanchnic oxygen saturation and regional lung ventilation in extremely low birth weight infants with or without reintubation during the 7 days post extubation.
The application of this multimodal monitoring approach using both clinical and physiological data during the postextubation period will help by making the assessment of clinical stability more comprehensive, more objective, more accurate, more standardized, and more reflective of important end-organ function. Thus, the proposed multimodal monitoring could lead to more informed decisions about reintubation and more individualized treatment plans during this critical period, hence potentially leading to better outcomes.

| Near infrared spectroscopy sensors | Device | The cerebral and splanchnic regional oxygen saturation signals will be acquired continuously for 168h post extubation using two near infrared spectroscopy sensors (Masimo ROOT platform, MasimoCorp, Irvine, LA), one placed on the forehead for cerebral oxygenation and one on the abdomen (for splanchnic oxygenation). |
|
| Electrical impedance tomography | Device | The regional lung ventilation will be measured using Electrical Impedance Tomography (TIMPEL, USA) at three time points:

|
| 168 hours |
| To describe longitudinal cerebral oxygen saturation patterns for infants with and without reintubation during the 7 days post-extubation | The variable will be longitudinally described and graphically displayed using mean (standard deviation), median (interquartile range), or number (percentage) for the hour pre-extubation and for each 24-hour bin post-extubation, and compared between infants requiring reintubation and those not requiring reintubation during the 7 days after extubation. | 168 hours |
| To describe longitudinal splanchnic oxygen saturation patterns for infants with and without reintubation during the 7 days post-extubation | The variable will be longitudinally described and graphically displayed using mean (standard deviation), median (interquartile range), or number (percentage) for the hour pre-extubation and for each 24-hour bin post-extubation. Repeated measures one-way ANOVA or Friedman test will be used to evaluate for differences in the variables over time. | 168 hours |
| To describe regional lung ventilation from the immediate pre-extubation period until 72-96 hours post-extubation. | The variable will be longitudinally described and graphically displayed using mean (standard deviation), median (interquartile range), or number (percentage) for the hour pre-extubation and for each 24-hour bin post-extubation. Repeated measures one-way ANOVA or Friedman test will be used to evaluate for differences in the variables over time. | 96 hours |
