Description

For clinicians, the ability to accurately predict which infants will successfully extubate is essential. Doctors and nurses routinely use a combination of vital signs (heart rate, respiratory rate, oxygen saturations), physical examination and spontaneous breathing trials to determine a baby's readiness to have their breathing tube removed. A spontaneous breathing trial is routinely done in our NICU and involves reducing the support that the baby receives from the breathing machine while leaving the breathing tube in place. These methods do not always accurately predict which babies are ready to be extubated.

This prospective observational pilot study will measure work of breathing (how hard or how easy a baby breathes) before, during and after the routine spontaneous breathing test is done. The study will also measure work of breathing before and after removal of the breathing tube, if a baby's medical team decides the baby is ready to have their tube removed.

Work of breathing indices will be measured through respiratory inductive plethysmography (RIP). Soft elastic cloth bands will be placed around the baby's chest and abdomen. These bands measure how well the chest and abdomen work together when a baby breathes. We hypothesize that PneuRIP can predict extubation failure.
