Apnea, Positive Pressure Ventilation, Preterm Infants
Conditions
Brief summary
Positive pressure ventilation (PPV) is the most important intervention in neonatal resuscitation. During PPV, it is important to hold the face-mask with care, as applying excessive pressure could cause injury to the infant, while insufficient pressure could be a contributor of mask leak and reduced effective ventilation. Application of positive pressure to face structures may trigger a vagally mediated reflex via the trigeminal nerve that innervates the skin of the face leading to apnoea and a decrease in heart rate (TCR, trigeminal-cardiac reflex). In neonatal manikins, ventilation with a partially or fully inflated face mask does not seem to result in differences in mask leak. The force exerted by providers to improve mask seal might result in pressure lesions and in the elicitation of the trigeminal-cardiac reflex. However, information about the applied forces is unknown.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Applied forces on the manikin face | 1 minute | The forces applied by the participants to the manikin face will be measured by sensors positioned on the manikin face |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cuff pressure | 1 minute | The pressure inside the mask will be measured during the procedure |
| Percentage of ventilation time with leak less than 25% around the mask | 1 minute | The mask leak willbe measured by using a respiratory function monitoring during theprocedure |
Other
| Measure | Time frame | Description |
|---|---|---|
| Participants' opinion on the procedures | 5 minutes | Participants will be asked to rate both procedures by using a Likert scale (Likert scale from 1 lowest grade to 5 highest grade) |
