How we source clinical content

Every clinical statement on PediaSuite is checked against primary sources, and each calculator and article lists the references it relies on. The core sources are:

• American Academy of Pediatrics and American Heart Association, Textbook of Neonatal Resuscitation, 9th edition (2025).
• Lee HC, et al. Part 5: Neonatal Resuscitation. 2025 AHA/AAP Guidelines for CPR and Emergency Cardiovascular Care. Circulation. 2025. doi:10.1161/CIR.0000000000001367
• Liley HG, et al. Neonatal Life Support: 2025 ILCOR Consensus on Science With Treatment Recommendations. Circulation. 2025. doi:10.1161/CIR.0000000000001363
• Peer-reviewed studies and AAP clinical reports for specific formulas and doses, cited on the page where they're used and verified against PubMed.

How pages are reviewed

Each calculator shows who reviewed it and when. Content is re-checked when a new NRP edition or AHA/AAP guideline update is published, and dosing tools are checked against the cited source before any change goes live.

Corrections

If you find an error or a statement that doesn't match the current guideline, email support@pediasuite.com with the page and the source. Clinical corrections are reviewed and fixed as a priority.
