| 60% – 51% | 8% – 9% | Organ Failure Stage | Multiple Organ Failure 🔥 | ❌ Extreme Risk | ICU + Ventilator + Life Support |
| 50% – 41% | 6% – 7% | Near Death | Brain Damage 🧠❌ | ☠️ Fatal Risk | Life Support + Critical Care |
| Below 40% | Below 6% | Death Stage | No Brain Activity ⚰️ | ☠️ Death Risk | No Recovery Possible |
1. Normal (100% – 96%) ✅
You’re living the dream, bro! This is how your body is supposed to be — no symptoms, lungs working perfectly 🫁, and your brain firing up 💪. Chill out, nothing to worry about 🔥.
2. Mild Hypoxemia (95% – 91%) ⚠️
Okay, now you’re starting to feel a little breathless 🫁. This happens at high altitudes or during sickness. It’s low risk but don’t ignore it — keep monitoring your oxygen levels.
3. Moderate Hypoxemia (90% – 86%) 🔥
Bro, this is where your body starts freaking out. Dizziness, fatigue 😓, and tired vibes all day long. You need oxygen support ASAP — don’t play with this level!
4. Severe Hypoxemia (85% – 81%) 🔴
Confusion kicks in 💥, chest pain starts, and your brain slows down 🧠. This is high risk, bro! You need immediate oxygen therapy or you’ll end up in the ICU 🚨.
5. Critical Hypoxemia (80% – 71%) 🚨
Now you’re in the danger zone! Your lips turn blue, you feel unconscious, and your organs are starving for oxygen. Without emergency medical help, your body is seconds away from shutting down ❌.
6. Life-Threatening (70% – 61%) ⚠️❌
Bro, you’re one step away from death! Organs are shutting down, shock is setting in, and your body can’t survive without ICU and ventilator support. This is extreme danger — only hospital vibes can save you now.
7. Organ Failure Stage (60% – 51%) 🔥❌
At this point, your organs are dying one by one 🔥. Brain, liver, heart — everything is failing. Ventilators and life support machines are your only hope.
8. Near Death (50% – 41%) ☠️
Brain damage is kicking in 🧠❌, and recovery chances are almost zero. Without critical care, it’s game over, bro.
9. Death Stage (Below 40%) ☠️💀
No brain activity, no heartbeats — this is the final stage. At this level, recovery is not possible. The body shuts down completely, and death is certain ⚰️.
Final Advice 🔥
Oxygen is life, bro! If your SpO₂ level goes below 95%, don’t ignore it. Get medical help, use oxygen support, and stay hydrated. Your body can’t survive without oxygen — protect your lungs at all costs 🫁💪.
