Hi Everyone, I've taken the NRP online exam and completed it but am to do the skills eval soon and do not know the ans to this ques which not only will I need to know but want to know for real life purposes. I've looked through the textbook and even googled it and can not seem to find the ans.... with a premature infant..I read that you use an O2 blender and titrate to the expected spO2 based on age in mins but if apneic or in resp distress how much O2 % do you initally administer when you first begin PPV? Just RA or 30% etc? Since the concern is to avoid significant O2 changes in too short a time it seems a very sensitive topic to me... Thank you for any info!:)
