Only battery-operated devices are safe. Failure to use child safety plugs in all outlets, and keeping children away from electrical cords. Adjusting prongs of an electrical cord that are too wide or narrow them with your fingertips while simultaneously plugging the cord into the power mains. The power plug used in the UK and some Commonwealth countries provides limited protection (Type G, with the lower half of the live prongs insulated), but all others do not. Not following manufacturer safety instructions for electrical appliances. This includes not using and immediately unplugging any appliance with a damaged electrical cord. If this cannot be done safely (i.e. damage is too close to the plug), the circuit breaker should be turned off beforehand. Touching metallic areas of an AC electrical appliance while also simultaneously touching faucets, water pipes, another metallic AC appliance, or being even partly immersed in water (including wet feet). This could ground the body through metal or water, with the risk that a faulty appliance is electrically "hot" on its outside cover or chassis. Not installing Ground Fault Circuit Interrupter (GFCI) outlets or circuit breakers in all areas with plumbing, bare concrete flooring, exposed to the elements, or outdoors by a qualified electrician. (Many newer homes already have these devices pre-installed.) Running an extension cord from non-GFCI areas such as bedrooms and hallways defeats this safety feature. Oral burns (above) cannot be prevented by GFCI.
As metabolic bicarbonate production becomes exhausted, and extraneous bicarbonate infusion can no longer reverse the extreme buildup of carbon dioxide associated with uncompensated respiratory acidosis, mechanical ventilation will usually be applied. Fetal respiratory acidemia
In the fetus, the normal range differs based on which umbilical vessel is sampled (umbilical vein pH is normally 7.25 to 7.45; umbilical artery pH is normally 7.20 to 7.38). In the fetus, the lungs are not used for ventilation. Instead, the placenta performs ventilatory functions (gas exchange). Fetal respiratory acidemia is defined as an umbilical vessel pH of less than 7.20 and an umbilical artery PCO2 of 66 or higher or umbilical vein PCO2 of 50 or higher. See also
