Introduction
Feeling constantly tired or short of breath even during light activity? Your body might be low on oxygen and could need immediate attention.
Low blood oxygen levels (hypoxemia) often go unnoticed, especially among the elderly, post-COVID patients, those with asthma, or lung issues. This guide explains the signs of oxygen deficiency, common causes, and how to boost oxygen safely at home.
1. What Is Low Oxygen (Hypoxemia)?
Hypoxemia is a condition where the oxygen level in the blood falls below the normal range:
Normal range: 95% – 100% (SpO2)
Danger level: Below 90% (requires urgent care)
You can check your oxygen levels using a pulse oximeter, a small and affordable digital device.
2. Signs Your Body Is Low on Oxygen
Look out for these symptoms:
Fatigue or general weakness
Shortness of breath or gasping
Dizziness or headaches
Blue lips or fingertips
Fast heartbeat
Difficulty sleeping or feeling restless
⚠️ Elderly patients and those with chronic illness may show subtle symptoms — regular checks are important.
3. Common Causes of Oxygen Level Drop
These are typical causes of hypoxemia:
Lung infections (e.g., pneumonia, COVID-19)
Asthma or COPD (Chronic Obstructive Pulmonary Disease)
Heart failure
Severe anemia
Poor ventilation or exposure to polluted air
4. Dangers of Untreated Oxygen Deficiency
Without treatment, low oxygen levels can lead to:
Organ damage
Brain and heart failure
Loss of consciousness
Sudden death
According to WHO, low oxygen saturation was one of the major contributors to COVID-19-related deaths.
5. How to Increase Oxygen Levels at Home
You can try these home remedies:
Use or rent an oxygen concentrator — it delivers pure oxygen continuously
Improve ventilation by opening windows
Practice deep breathing exercises
Elevate the head during sleep
Avoid smoking or enclosed, stuffy areas
Oxygen machines are highly recommended for elderly or long-term respiratory care patients.
Did You Know?
Oxygen concentrators can deliver 5–10 litres of oxygen per minute depending on the model
Over 30,000 machines were rented during the COVID-19 peak in Malaysia
Most families prefer renting over buying for cost-effectiveness and convenience
Conclusion
Low oxygen is not something to take lightly — it can be life-threatening if not treated early. If you’re experiencing symptoms like breathlessness or fatigue, get your oxygen level checked and seek medical help.
The most practical solution? Use an oxygen machine at home. Whether renting or buying, always choose a trusted provider.
