Comparative StudyMaximizing the stability of oxygen delivered via nasal cannula.
The effective fractional inspired oxygen concentration (FiO2) of supplemental oxygen provided to infants via nasal cannula may be adjusted by changing cannula flow rate or oxygen concentration, factors within our control. However, FiO2 also varies with changes in the patient's breathing, factors beyond our control. While a stable oxygen delivery is desirable, combinations of flow and concentration that maximize stability over time need to be studied. ⋯ To minimize variability in oxygen delivery via nasal cannula to infants, cannula flow should be reduced to the lowest possible flow by using undiluted (100%) oxygen. Supplemental oxygen may then be weaned by making small reductions in cannula flow. Cannula oxygen concentration should be reduced below 100% only after the minimum calibrated flow rate is reached. Such a strategy may maximize the stability of delivered oxygen over time as well as minimize the size of changes in delivered oxygen at each step of the weaning process.

Association between bicycle helmet legislation, bicycle safety education, and use of bicycle helmets in children.
To determine the association between bicycle helmet legislation and bicycle safety education and the use of bicycle helmets by children under age 16 years. ⋯ There was a dramatic association between reports of increased helmet use and bicycle helmet legislation plus education; the association was stronger than that found with legislation only.
