A pulse oximeter is a non-invasive medical device used to measure the oxygen saturation level (SpO2) and pulse rate of an individual. It typically clips onto a fingertip, though it can also be attached to other body parts such as the earlobe or toe. The device works by emitting light through the skin and measuring the amount of light absorbed by oxygenated and deoxygenated blood.
Key features of a pulse oximeter include:
Display Screen: Shows the oxygen saturation percentage and pulse rate.
LED Sensors: Emit red and infrared light to measure blood oxygen levels.
Battery Operated: Often powered by batteries for portability.
User-Friendly: Usually simple to operate, requiring minimal training.
Pulse oximeters are widely used in medical settings, during surgeries, and by individuals at home to monitor respiratory conditions.

I say World’s best teas so as not to limit the excellence of Vahdam teas to a single leaf. I know there might be some argument about this statement by some but if so, they surely haven’t tried Vahdam teas. It is and will always be my go-to purchase as I like to indulge myself with the freshest and best.

I don\’t know if there is something wrong with this bag of tea in particular. The taste is bad. I tried 1 regular cup and was instantly nauseated. I tried another very diluted cup and I was still sick. I am returning the tea.

Firm yet soft, perfect support. Smelled like chemical death when it first arrived but after a few weeks it has no smell. Cured my backpain and I can fold it into a sofa against the wall during the day!
