| Abstract | ObjectiveTo measure the irradiance in humidifi ed
incubator under three different overhead phototherapy
devices.
Design/methodsThe effective irradiance of three
phototherapy devices was assessed by taking a series
of irradiance measurements in the illuminated fi eld.
Measurements were made with a fi xed bandwidth
broadband radiometer (380–530 nm). The distance
between the light source and the radiometer was
35 cm for the daylight fl uorescent lamp , 40 cm for the
light emitting diode (LED) and 50 cm for the halogen
phototherapy. A double-wall incubator was kept at 36°C
and set at three different levels of humidity (60–70%,
80% and equal or above 90%).
ResultsThe irradiance under the overhead daylight
fl uorescent lamp phototherapy did not change with the
increasing humidity. However, above 90% humidity,
when water vapour inside the incubator was so
saturated to the point of totally condensing in the
incubator walls, the measured irradiance decreased 15%
of the initial values with the blue LED phototherapy and
45% with the halogen spotlight phototherapy.
ConclusionsHighly humidifi ed incubators are
frequently used to treat very low birthweight infants.
Health professionals should be aware that mist and
water condensation inside an incubator may signifi cantly
reduce the effi cacy of treatment. | pt_BR |
