Abstract
A method for quantifying airflow, in the form of a measured airflow rate, through a porous surface. The method is particularly useful for ventilated sleep surfaces used to prevent SIDS. Provided that one knows the correlation between air flow rate and CO washout times, the resulting measured airflow rate provides an indication of whether a ventilated sleep surface is providing sufficient airflow to effectively dissipate the CO . One can determine the minimum measured airflow rate that is effective to provide a minimum adequate level of CO dispersal. Thus, a ventilated sleep surface system that produces an air flow sufficient to result in the minimum airflow rate, as measured by a suitable airflow meter, can effectively dissipate CO and reduce the risk of SIDS.
