    The effect of liquid between the electrode pads of AED(automated external defibrillator) on the output energy has been investigated by using the tap water, physiological saline water, and 3.5% NaCl water solution. The decrease in voltage, shorting of output time, and reduction of output energy were observed when the pathway was built up by physiological saline water or 3.5% NaCl water solution. In the case of the tap water and droplet of physiological saline water or 3.5% NaCl water solution, the remarkable change in the output voltage and energy were not observed. These results mean that the energy loss is negligible small if the pathway does not exist between the electrode pads of AED. Thus we need to wipe the liquid on the surface of patient in order to remove the pathway of it when the BLS is performed for the wet patient.

    We previously revealed the mechanisms of the bubble generation in infusion lines and investigated preventive methods of generating the bubbles. In the present study, we investigated the frequencies of the alarm activations for generating bubbles in infusion lines by the infusion pump under clinical settings. We compared the alarm frequency by the pumps used in general wards to that in the intensive care unit (ICU). Alarms in general wards were significantly frequently than those in the ICU. Quakes, which is derived from patients’ ambulation, might cause bubbles in infusion lines.

    The hyperbaric oxygen therapy (HBOT) is administered for sudden deafness, intestinal obstruction, carbon monoxide poisoning. If flammable materials such as silk, wool, synthetic textile materials or disposable body warmer which utilizing the exothermic reaction were brought into the HBOT monoplace chamber, it may cause fire or explosion. In order to avoid such accidents, the patient should understand the therapy principle and the dangerousness of such materials, and also the medical staffs should check carefully the patient's body whether the patient has such flammable materials involuntarily. Currently, the check is performed by a body search, in addition to visual inspection and oral questions by several staffs. However the disposable body warmer is hard to find especially when it's adhered to underwear because it's very thin and the medical staffs also have to concern the patient's privacy. In this study, we have developed a system which detects the disposable body warmer noninvasively and quantitatively by infrared thermal sensorsThe proposed system may be useful as complement of the current body search protocol.
