Datex-Ohmeda Spot Phototherapy Lamp provides a very high irradiance but only over a small area19,31 and the Hill-RomMicro-Lite Phototherapy System provides a medium irradiance but over a limited area. Ohmeda BiliBlankets have a high irradiance but small effective treatment area, but this disadvantage is offset by the versatility of the device.
We can conclude that not all phototherapy devices are equally effective. When their characteristics are compared to
the three important criteria identified more informed decisions can be made about the device chosen to administer
phototherapy. Care must be taken in choosing a device which will be effective and also be easy to use and acceptable to
the clinical users and parents.
