Phototherapy device controller

A controller of a phototherapy apparatus including a light source for illuminating a patient to treat an inflammatory condition, the controller including:

• memory and processor circuitry configured to:
• receive respiratory data from a respiration sensor of the phototherapy apparatus, wherein the respiration sensor comprises at least one of a breathing rate sensor or a blood oxygen sensor;
• store respiratory information in the memory based on the received respiratory data;
• receive blood test results of the patient comprising a measure of a compound in the blood, wherein the measured compound includes at least one of Interleukin 6, Interleukin 9, or C-reactive protein (CRP);
• store blood test information in the memory based on the received blood test results;
• and
• control emission of electromagnetic radiation by the light source based on the respiratory information and the blood test information by modulating a property of the electromagnetic radiation emitted by the light source, such that:
• the property of the electromagnetic radiation being emitted is decreased in response to a positive trend in the respiratory information over a duration of time, wherein:
• the positive trend in the respiratory information over the duration of time comprises at least one of
• a decrease in a breathing rate of the patient over the duration of time greater than a breathing rate change threshold;
• or
• an increase in the blood oxygen level of the patient over the duration of time greater than a blood oxygen change threshold;
• and
• when the blood test information includes a positive indication due to a decrease in the measured compound over the period of time, escalating the amount of the decrease in the property of the electromagnetic radiation being emitted in response to the positive trend in the respiratory information over the duration of time;
• or
• when the blood test information includes a negative indication due to an increase in the measured compound over the period of time, lessening the amount of the decrease in the property of the electromagnetic radiation being emitted in response to the positive trend in the respiratory information over the duration of time;
• and
• the property of the electromagnetic radiation being emitted is increased in response to a negative trend in the respiratory information over the duration of time, wherein:
• the negative trend in the respiratory information over the duration of time comprises at least one of:
• a decrease in the breathing rate over the duration of time less than the breathing rate change threshold;
• or
• an increase in the blood oxygen level over the duration of time less than the bloody oxygen change threshold;
• when the blood test information includes a positive indication due to a decrease in the measured compound over the period of time, lessening the amount of the increase in the property of the electromagnetic radiation being emitted in response to the negative trend in the respiratory information over the duration of time;
• or
• when the blood test information includes a negative indication due to an increase in the measured compound over the period of time, escalating the amount of the increase in the property of the electromagnetic radiation being emitted in response to the negative trend in the respiratory information over the duration of time;
• wherein the property of the electromagnetic radiation comprises at least one of optical dose, optical intensity, time duration of emission, fluence, wavelength, or optical power.
