Abstract: A device performs oxygen flight planning calculations for estimating oxygen usage. The device includes a storage device, an input device for inputting a known flight parameter value into the storage device, and an output device for outputting the known flight parameter value input by the input device. A logic device is configured to control the storage device, the input device, the output device and provide to the output device a further flight parameter. A value of the further flight parameter is calculable by the logic device from the known flight parameter value previously input into the storage device. Upon the further flight parameter being selected by use of the input device, the logic device calculates the value of the further flight parameter and provides the value of the further flight parameter to the output device.

Abstract: A noninvasive system for monitoring the oxygen saturation level of a person subjected to reduced atmospheric pressure for avoiding hypoxemia. The system monitors a person's oxygen saturation level, comparing the saturation level to a predetermined level. When the measured saturation level is less than the predetermined level, the person is then supplied with an oxygen mixture for increasing the subject's oxygen saturation level to a safe level. The person's exposed reduced atmospheric pressure is also compared with a predetermined range of pressure levels. If this predetermined range of pressure levels is exceeded or maintained for a predetermined time duration, the person is then supplied with an oxygen mixture. Additionally, a device is provided for performing oxygen flight planning calculations for estimating oxygen usage for a predetermined flight plan that is based on the above system.
