Carbon dioxide rebreathing induced by crib bumpers and mesh liners using an infant manikin.

Objectives: Quantify impaired respiration in currently marketed crib bumpers (CBs), mesh liners (MLs) and alternative products (ALTs) used to attenuate the interaction between the baby and the crib sides and elucidate the relationship between impaired respiration and permeability.

Methods: We experimentally quantified carbon dioxide rebreathing (CORB) via an infant manikin and air permeability via previously published test protocols, in commercially available CBs, MLs and ALTs.

Results: Differences in CORB in ML (median [m]=8.
