Heart Rate (Pulse)
Heart rate indicates how many times the heart beats per minute (BPM). It varies based on activity, age, emotions, and fitness level.
Normal Resting Heart Rate: 60–100 BPM
Athletes: Often 40–60 BPM due to stronger heart muscle
A consistently high heart rate (tachycardia) or low heart rate (bradycardia) can signal underlying health issues such as arrhythmias, heart disease, or hormonal imbalances.
Ways to Monitor:
- Manually via the radial pulse (wrist)
- Wearable devices (smartwatches, fitness bands)
- Medical monitors (ECG, pulse oximeters)
Blood Vitals offers a clear, one-touch solution.
Blood Oxygen Level (SpO2)
SpO2 measures the oxygen saturation in the blood, reflecting how efficiently oxygen is being transported to the organs.
Normal SpO2: 95%–100%
Levels below 90% indicate hypoxemia, which can be life-threatening and may be caused by:
- Lung diseases (COPD, asthma, pneumonia)
- Sleep apnea
- COVID-19 and other infections
- Anemia or circulatory issues
Pulse oximeters, clipped to a finger, provide quick and non-invasive readings. Monitoring SpO2 is especially important for patients with respiratory or cardiac conditions.
