Ear-wearable health monitoring system

An apparatus, comprising:

• a wearable device configured to be positioned on an ear of a wearer, the wearable device including a first body portion, a second body portion, and a connection member mechanically coupled to each of the first body portion and the second body portion, at least one of the first body portion or the second body portion having a processor, a memory operably coupled to the processor, and a sensor set including at least one of a pulse oximeter, a photoplethysmography (PPG) sensor, an accelerometer, a temperature sensor, a proximity sensor, an ambient light sensor, or a gyroscopic sensor, the memory storing instructions to cause the processor to calculate a blood oxygen saturation level of the wearer and at least two of:
• calculate a pulse rate of the wearer;
• calculate a blood pressure level of the wearer;
• calculate a blood flow rate of the wearer;
• identify a cardiac output/rhythm of the wearer;
• calculate a blood sugar level of the wearer;
• calculate a blood carbon monoxide level of the wearer;
• calculate a blood nitrous oxide level of the wearer;
• generate an electrocardiogram associated with the wearer;
• estimate a risk of one of dementia or Alzheimer's disease of the wearer by analyzing at least one of blood pressure variability (BPV), pulse wave velocity (PWV), and pulse transit time (PTT);
• or
• detect peripheral artery disease (PAD) of the wearer based on a pulse wave form detected via the wearable device.
