If the pandemic taught us anything, it is that oxygen levels can be just as important to keep an eye on as blood pressure or temperature. That is where a pulse oximeter comes in. These small fingertip devices measure your blood oxygen saturation (SpO2) and pulse rate within seconds, giving you a quick snapshot of how well your body is delivering oxygen.
Once considered equipment only for hospitals and clinics, pulse oximeters are now common in households, especially for people managing conditions like asthma, COPD, sleep apnea, or recovering from respiratory infections. Athletes, hikers, and even frequent flyers also find them useful for monitoring oxygen levels during physical activity or at high altitudes.
But not all pulse oximeters are built the same. Some models focus only on basic SpO2 and heart rate readings, while others add extra features like perfusion index, memory storage, or Bluetooth connectivity for data tracking. Accuracy, ease of use, display quality, and battery life also vary widely between brands.
