Pulse Oximeter (Finger Blood Oxygen)
Having a pulse ox at home may help with your desire to have some control during an overwhelming situation like a pandemic -- but it may also create more stress. If you are short of breath from climbing a set of stairs, you may have not noticed before, but experts worry that people without a medical degree might jump to conclusions.
Pulse oximeters are medical devices that monitor the level of oxygen in a patient's blood and alert the health-care worker if oxygen levels drop below safe levels, allowing rapid intervention. These devices are essential in any setting in which a patient's blood oxygen levels requires monitoring like operations, emergency and intensive care, and treatment and recovery in hospital wards.
