Determination of intensity and spread of light to the surrounding in conventional phototherapy and comparison with novel converging photo unit — an observational study

Abstract Background Blue light phototherapy used extensively in the management of hyperbilirubinemia has many side effects like dry eyes, blurring, headache, and altered circadian rhythm. Healthcare providers working around are unduly exposed to these effects. Altered rhythm results disruption sleep-wake cycle affecting healthcare particularly during night shift. The constant glare blue interrupts clinical observation baby on phototherapy. With intent providing effective with minimal exposure providers, a source called photo unit was designed developed. objective this study estimate intensity spread surrounding conventional compare same newly developed converging unit. Results therapeutic range irradiance noted up 22 inch diameter compared only 7 our seen beyond 50 all directions whereas confined 19-inch Conclusion Photo by authors divergence surrounding, thereby mitigating people vicinity. Multiple units can be make device.
