Abstract : One of the fastest growing forms of medical technology, pulse oximetry, provides continuous, noninvasive monitoring of a patient's arterial hemoglobin saturation (SaO2). It provides a quick indication of a patient's changing level of SaO2, allowing for medical intervention before significant hypoxia occurs. The 375th Aeromedical Airlift Wing (375 AAW/SGNL; now HQ Air Mobility Command/SG) requested Aeromedical Research Function (now a function of Armstrong Laboratory/CFTS) to evaluate the Biochem microSpan 1040A pulse oximeter for patient use in the aeromedical evacuation environment. It was found that an acceptable battery charger, rated at 110 VAC/60-400 Hz with a 1000 microF capacitor, would reduce the pulsation caused by the half-wave rectified charger. Internal battery securing screws must have lock washers in place to prevent them from loosening. The bonding of the mounting bracket knob to the shaft must be improved. The protruding wire between the circuit boards that allowed a 4 MHz signal to escape must be tucked between the circuit boards to shield this wire and prevent EMI. If these requirements are met, the Biochem microSpan 1040A pulse oximeter is a safe and reliable device for monitoring changing levels of patient oxygenation and is acceptable for aeromedical evacuation use....
