MSC15-Bili : Blue Light Spectrum
Product Descriptions
Blue light phototherapy
Blue light phototherapy is the most common therapeutic intervention used for the treatment of unconjugated neonatal hyperbilirubinemia.
The effectiveness of phototherapy is influenced by several parameters. These include the light spectrum, the distance between the light source and the exposed surface, the irradiation intensity, the exposed surface area and the irradiation time. Light in the spectral range of approximately 400 to 500 nm, with a peak at 460 nm +/-10 nm, is considered the most effective for the treatment of hyperbilirubinemia.
The usual light sources are blue fluorescent tubes and blue-emitting light emitting diodes (LED).
Every light source ages
As light sources age, their radiation intensity usually decreases with the number of operating hours. For this reason, it is common practice for the light intensity of phototherapy devices to be measured at routine intervals either by clinicians or specialist technicians.
Not every light source ages the same
This periodic control requires predictable aging behavior of each individual lamp. If a light source ages faster, there is a risk of too low an irradiation dose resulting in extended or ineffective treatment.
In the UK for example, the latest guidelines used by the National Health Service (NHS) as issued by NICE (National Institute for Excellence in Health and Care) now recommend the measurement of irradiation intensity prior to each therapeutic treatment.
Spectral light meter MSC15-Bili
The MSC15-Bili is a compact spectral light meter for measuring irradiation intensity in blue light phototherapy. The meter is designed to measure the average and integrated irradiance. It does not require correction values for different phototherapy systems.
The meter provides individual display screens for each of the following metrics:
• AAP 2004 Guidance, 430 nm – 490 nm average irradiance in μW/cm2/nm
• AAP 2011 Guidance, 460 nm – 490 nm average irradiance in μW/cm2/nm
• IEC 60601-2-50 Total irradiance for bilirubin, Ebi, 400 nm – 550 nm in mW/cm2
• Spectral irradiance 360 nm – 830 nm including lux, CCT and x,y chromaticity
