1322 incubator humidity with different humidity reservoir baffle systems

ABSTRACT Although important in reducing heat and water losses from newborns, incubator humidities are difficult to predict and control. A removable metal baffle for use in an incubator


humidity reservoir has been recently modified by one manufacturer and contributes to this unpredictability. Using an electric hydrometer, the relative humidities (R.H.) of 7 Air-Shields


incubators were measured 1) with no baffle in the humidity reservoir, 2) with the manufacturer's older and larger iron baffle and 3) with a recently introduced smaller steel “W” shaped


baffle. Incubator temps. were servo controlled to 34°C, and full humidity reservoirs were opened to maximum settings. Both baffles increase incubator humidity, but the variability was


greater with the smaller steel baffles, and the 3.7% increase with this steel baffle is significantly less (p<0.01) than the 14.1% increase with the larger iron baffle. Since this


observation, excess heat and water losses from newborns have been corrected by replacing the newer and smaller baffles with the larger iron baffles. This experience reinforces the opinion


that incubators must not only be designed and modified carefully, but also used knowledgeably. ARTICLE PDF AUTHOR INFORMATION AUTHORS AND AFFILIATIONS * Department of Pediatrics, U.
