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>2< 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>2<. One can determine the minimum measured airflow rate that is effective to provide a minimum adequate level of CO>2< 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>2< and reduce the risk of SIDS. |
