Baby Breathing

I asked Chat GPT what Mike Leshner has done in the field of infant breathing...   this is what it said:

Michael Leshner, P.E., is a consulting professional engineer specializing in infant product safety, particularly focusing on breathability and firmness to mitigate breathing hazards. He chairs the ASTM Ad Hoc Juvenile Product Firmness and Breathability Task Group, leading efforts to develop standardized test methods for evaluating infant product safety. His work includes:

   •    ASTM Subcommittee Leadership: Leshner leads ASTM’s consumer products committee (F15) subcommittee on Firmness and Breathability of Juvenile Products (F15.12). This subcommittee addresses the need for infant-specific testing methods, focusing on surface firmness, airflow resistance, and carbon dioxide re-breathing. 

   •    Development of Test Methods: He is involved in creating test methods such as WK84613, WK84614, and WK84615, which cover surface firmness, airflow resistance, and carbon dioxide re-breathing, respectively. These methods aim to quantify “breathability” in infant products, providing manufacturers and laboratories with standardized guidelines. 

   •    Research and Testing: Leshner has conducted independent laboratory tests comparing various infant mattresses, including the numu® air™ baby sleep surface. His studies assess factors like air resistance, carbon dioxide dispersion, and heat dissipation to determine product safety and breathability. 

   •    Publications: He has authored studies on evaluating infant bedding materials, including “Thermal Rebreathing Model for Evaluation of Infant Bedding Materials,” published in the ASTM Journal of Testing and Evaluation. 

   •    Advocacy and Consultation: Leshner has engaged with regulatory bodies, such as the U.S. Consumer Product Safety Commission (CPSC), to discuss baby product safety and breathability research, contributing to policy discussions and safety standards.
