COVID Risk Chart

Oxygen saturation is one of the most sensitive and consequential metric in the early intervention and care of someone who is potentially challenged with COVID pneumonia. The early stages of COVID pneumonia causes low oxygen and low carbon dioxide. The combination of this physiology is experienced subtly as rapid breathing but not necessarily shortness of breath.

Experiencing these symptoms may not be so alarming that a person will immediately seek medical attention even though actual oxygen levels could be critically low (hypoxemia).   CIRCUL informs the wearer of this underlying low blood oxygen level so they can speak to their caregiver or physician and not miss this potentially severe condition.  Earlier intervention in COVID pneumonia development can save lives and reduce hospital stays.  ALWAYS consult with your physician before taking any action or inaction if you have any symptoms.
