Brief summary
The goal of this trial is to compare the time to first heart rate displayed for iRes Warmer with ResusView and using iRes Warmer without ResusView when used in the resuscitation (e.g. Cardiopulmonary resuscitation or breathing assistance) of premature newborns (23 to 32+6 weeks gestation).
Detailed description
This is a prospective interventional randomized control trial. Infants born between 23+0 and 32+6 estimated gestational age will be randomized using a computer generate allocation sequence stratified by gestational age. Randomization cards will be placed in opaque envelopes. For the intervention group, the care team will use the Panda iRes Warmer with ResusView Bed during resuscitation interventions in the first 10 minutes of life. During use of the iRes-warmer, standard nursing care of an infant on a radiant warmer will be followed. Participants assigned to the control group will receive interventions using the same model Panda bed without ResusView. There is no minimum time for monitoring, and the maximum time depends on clinical determination for use of heart rate feature for each resuscitation event. Data including the infant's gestational age, Electrocardiogram lead type and activities that occurred during resuscitation will be recorded for the first 10 minutes of life.
Interventions
Rapid heart rate display utilizing optimized ECG algorithm in iRes Warmer in babies delivered between 23+0 and 32+6 weeks estimated gestational age
Electrocardiogram monitoring using external ECG monitor in babies delivered between 23+0 and 32+6 weeks estimated gestational age
