Pulse Oximeter (Fingertip Device)
Non-invasive, painless tool available over-the-counter
Clips onto your finger and reads oxygen saturation (SpO₂) in seconds
Use tips:
Rest for 5 minutes before checking
Avoid cold hands or nail polish (can interfere)
Take multiple readings at different times
⚠️ Home devices are helpful for tracking — but not diagnostic. Always follow up with a doctor.
When to Seek Immediate Medical Help
Seek emergency care if you have:
Sudden shortness of breath
Chest pain or pressure
Blue lips or face
Confusion or fainting
Rapid breathing or heart rate at rest
These could signal a life-threatening issue like a heart attack, stroke, or pulmonary embolism.
For chronic conditions (like COPD), work with your doctor on an action plan — including when to adjust medications or oxygen therapy.
❌ Debunking the Myths
❌ “If I don’t feel breathless, my oxygen is fine”
False — some people adapt to low levels without obvious symptoms
❌ “I can boost oxygen by breathing deeply all day”
Not true — only helps temporarily; won’t fix underlying cause
❌ “Low oxygen only happens with lung disease”
No — heart issues, anemia, and sleep disorders also affect it
❌ “Home oximeters are always accurate”
They vary — use reputable brands and confirm concerns with a doctor
