A cloud based pulse oximetry system and method is provided that incorporates both a software and hardware component. The hardware component includes a limited use pulse oximetry probe having an energy source and data transmitting capabilities. The probe houses a light source and a light detector that compare and calculate the differences in the oxygen-rich versus oxygen-poor hemoglobin in the body part to which, it is attached. Data from the probe is collected, analyzed, and communicated using a cloud based computing system. The system may be used for collecting and analyzing pulse oximetry data for any medical need such as diagnosis of obstructive sleep apnea.
