ABSTRACT

Background: Hypothermia generates potentially severe complications in operating or recovery room. Forced air warmer is effective to maintain body temperature. Extremely low frequency electromagnetic field (ELF-EMF) is harmful to human body and mainly produced by electronic equipment including convective air warming system. We investigated ELF-EMF from convective air warming device on various temperature selection and distance for guideline to protect medical personnel and patients.

Methods: The intensity of ELF-EMF was measured as two-second interval for five minutes on various distance (0.1, 0.2, 0.3, 0.5 and 1meter) and temperature selection (high, medium, low and ambient). All of electrical devices were off including lamp, computer and air conditioner. Groups were compared using one-way ANOVA. P<0.05 was considered significant.

Results: Mean values of ELF-EMF on the distance of 30 cm were 18.63, 18.44, 18.23 and 17.92 milligauss (mG) respectively (high, medium, low and ambient temperature set). ELF-EMF of high temperature set was higher than data of medium, low and ambient set in all the distances.

Conclusion: ELF-EMF from convective air warming system is higher in condition of more close location and higher temperature. ELF-EMF within thirty centimeters exceeds 2mG recommended by Swedish TCO guideline.

Figure 3: ELF-EMF on the distance of 30cm

Mentions: ELF-EMF from long distance represented lower value in all kinds of temperature. Mean value of 0.3 meter distance was 18.637, 18.447, 18.239 and 17.928 mG respectively (high, medium, low and ambient temperature) over Swedish TCO guideline 2mG (Fig. 3). Measured values from the distance of 1 meter were under Swedish TCO guideline.
