I've noticed my SPO2 levels usually range from 96 to 98, but sometimes they drop to 90 before going back up to 96. I'm not sure which reading I should pay attention to. Also, my BPM is consistently over 100. Meanwhile, my mom, who's 51, has a normal BPM between 72 and 80. I'm worried if these symptoms could be related to any heart or lung issues, especially since I haven't had COVID. Could you give me some advice on this?

Understanding SPO2 Levels

• Normal SPO2 is typically 95-100%. Occasional drops to 90% can occur due to factors like poor circulation or device error.
• Consistent monitoring is key. If dips are frequent, consult a healthcare provider.

Elevated Heart Rate (BPM) Considerations

• A resting heart rate over 100 bpm may indicate conditions like anxiety, dehydration, or thyroid issues.
• Seek medical advice if accompanied by symptoms like dizziness or chest pain.

Potential Heart and Lung Issues

• Conditions such as arrhythmias or asthma could cause these symptoms. COVID absence doesn't exclude other causes.
• A thorough evaluation is recommended to rule out underlying issues.

Recommended Next Steps

• Monitor symptoms closely. Seek medical attention if they persist or worsen.
• Consider tests like pulse oximetry, ECG, or chest X-ray for further assessment.

Lifestyle and General Health Tips

• Support heart and lung health by staying hydrated, avoiding smoking, and managing stress.

When to Seek Emergency Care

• Immediate attention is needed for persistent low SPO2, chest pain, severe breathlessness, or fainting.
