Effective ventilation is the single most vital intervention to improve outcome of resuscitation in the neonatal population. Assessments of effective ventilations are based on clinical parameters, but may be difficult due to inexperienced personnel as well as observer variability. End tidal CO2 detectors (ETCO2) have been shown to improve effective ventilation in manikin model as well as in video recordings of selective infants where obstructive breaths were recognized objectively by means of lack of colour change.
This is a trial evaluating the use of a qualitative end tidal CO2 monitor device during mask ventilation in the delivery room. The investigators hypothesize that using a colorimetric carbon dioxide detector during mask ventilation, it could facilitate recognition of obstructed breaths and reduce the duration of bradycardia and desaturations.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Monitor | Experimental | Qualitative End Tidal Co2 detector will be attached to the face mask used to provide mask ventilation to the preterm baby before connected to the T piece resuscitator. Respiratory function monitor sensor will be placed within circuit to measure parameters e.g. PIP, PEEP, FiO2, tidal volume. |
|
| Control | No Intervention | face mask used to provide mask ventilation to the preterm baby will be connected directly to the T piece resuscitator. Respiratory function monitor sensor will be placed within circuit to measure parameters e.g. PIP, PEEP, FiO2, tidal volume. |
