| [* black] And now, what you’ve been all waiting for: in-action shot of pulse oxymeter ([https://m.media-amazon.com/images/M/MV5BMjA0MDI1MTQ1Ml5BMl5BanBnXkFtZTcwMTQxMDQyMQ@@._V1_.jpg|light show|new_window=true]) | |
| [* icon_note] By bouncing a Christmas-y array of red, green, and infrared lights onto your skin, then watching how they bounce back with photodiodes, the sensor can tell how oxygenated your blood is. | |
| [* black] Blood that's oxygenated is bright red inside your body, dark red when it lacks for oxygen, and each reflects light differently. | |
| [* black] Having low blood oxygen, or hypoxemia, can indicate COVID-19 or other medial issues, as your lungs may not be absorbing enough oxygen, or your organs need more than normal to function. | |
