an oxygen mask; a fastener on an outer surface of the housing, wherein the fastener is capable of attaching the housing to an outer surface of the oxygen mask when the oxygen mask is placed over the mouth of the user; a temperature sensor connected to the housing via an adjustable arm and capable of detecting a surface temperature of the user's skin covered by the oxygen mask when the oxygen mask is placed over the mouth of the user; and one or more processors located within the housing, said one or more processors configured to execute machine executable code causing the one or more processors to: continuously receive data output from the temperature sensor, said data indicating a surface temperature of the user's skin; process the data received during a first period of time to identify an initial respiration rate of the user based solely on changes in surface temperature of the user's skin during the first period of time; process the data received during a second period of time to identify, one or more respiratory events corresponding to one or more deviations from the initial respiration rate; and generate an output indicating the one or more respiratory events. ### Claim 2 (depends on 1) The system of claim 1 further comprising a digital display located within the housing, wherein the machine executable code further causes the one or more processors to display on the digital display an alert indicating the one or more respiratory events. ### Claim 3 (depends on 1) The system of claim 1, wherein the temperature sensor is a thermopile and the system is configured to locate the thermopile adjacent to a vent in the oxygen mask. ### Claim 4 (depends on 3) The system of claim 3, wherein the thermopile is situated to receive thermal radiation from the user's skin surface through the vent in the oxygen mask. ### Claim 5 (depends on 1) The system of claim 1, further comprising an air pressure sensor and the system is configured to locate the air pressure sensor adjacent to a vent in the oxygen mask. ### Claim 6 (depends on 1) The system of claim 1, wherein the one or more respiratory events are one or more respiratory disorders selected from the group consisting of Tachypnoea, Bradypnoea, Apnea, Dyspnoea, Cheyne-Stokes, Ataxic Breathing, and Hyperventilation. ### Claim 7 (depends on 1) The system of claim 1, further comprising a vibration motor, wherein the output indicating the one or more respiratory events activates the vibration motor. ### Claim 8 (depends on 1) The system of claim 1, further comprising a speaker, wherein the output indicating the one or more respiratory events causes the speaker to emit an audible sound. ### Claim 9 (depends on 1) The system of claim 1, wherein the output indicating the one or more respiratory events is transmitted to another device. ### Claim 10 (depends on 1) The system of claim 1, wherein the output indicating the one or more respiratory events causes a telephony device paired with the system to transmit a message. ### Claim 11 A system for monitoring one or more respiratory attributes of a user, comprising: an oxygen mask having a vent; a temperature sensor located adjacent to the vent of the oxygen mask via an adjustable arm and capable of detecting a surface temperature of the user's skin covered by the oxygen mask when the oxygen mask is placed over the mouth of the user; and one or more processors located on the oxygen mask, said one or more processors configured to execute machine executable code causing the one or more processors to: continuously receive data output from the temperature sensor, said data indicating a surface temperature of the user's skin; process the data received during a first period of time to identify an initial respiration rate of the user based solely on changes in surface temperature of the user's skin during the first period of time; process the data received during a second period of time to identify one or more respiratory events corresponding to one or more deviations from the initial respiration rate; and generate an output indicating the one or more respiratory events. ### Claim 12 (depends on 11) The system of claim 11 further comprising a digital display located on the oxygen mask, wherein the machine executable code further causes the one or more processors to display on the digital display an alert indicating the one or more respiratory events. ### Claim 13 (depends on 11) The system of claim 11, wherein the temperature sensor is a thermopile and the thermopile is attached to the outside of the oxygen mask when the oxygen mask is placed over the mouth of the user. ### Claim 14 (depends on 13) The system of claim 13, wherein the thermopile is situated to receive thermal radiation from the user's skin surface through the vent in the oxygen mask. ### Claim 15 (depends on 11) The system of claim 11, wherein the system further comprises an air pressure sensor located adjacent to the vent in the oxygen mask. ### Claim 16 (depends on 11) The system of claim 11, wherein the one or more respiratory events are one or more respiratory disorders selected from the group consisting of Tachypnoea, Bradypnoea, Apnea, Dyspnoea, Cheyne-Stokes, Ataxic Breathing, and Hyperventilation. ### Claim 17 (depends on 11) The system of claim 11, further comprising a vibration motor, wherein the output indicating the one or more respiratory events activates the vibration motor. ### Claim 18 (depends on 11) The system of claim 11, further comprising a speaker, wherein the output indicating the one or more respiratory events causes the speaker to emit an audible sound. ### Claim 19 (depends on 11) The system of claim 11, wherein the output indicating the one or more respiratory events is transmitted to another device. ### Claim 20 (depends on 11) The system of claim 11, wherein the output indicating the one or more respiratory events causes a telephony device paired with the system to transmit a message.
