You can estimate your oxygen level without specialized equipment by monitoring your respiratory rate. While this doesn't provide a precise oxygen saturation percentage (SpO2) like a pulse oximeter, it offers an indication of your breathing efficiency.
Estimating Oxygen Levels Through Respiration Rate
One method involves timing your breaths. Set a timer for 30 seconds and count how many times you breathe in and out. Double this number to get your respiratory rate per minute. A respiratory rate significantly above 24 breaths per minute might suggest a potential issue that warrants further investigation by a healthcare professional. However, a normal respiratory rate doesn't guarantee adequate oxygen levels. Other factors affect oxygen saturation.

Procedure:
- Find a comfortable, quiet place to sit or lie down.
- Set a timer for 30 seconds.
- Count your breaths (inhales and exhales) during the 30 seconds.
- Multiply the count by two to estimate your breaths per minute.

Interpretation: While a respiratory rate of less than 24 breaths per minute is often considered within the normal range, it's crucial to remember that this is just a rough estimate. Other factors like heart rate and overall health influence blood oxygen levels. This method is not a substitute for professional medical advice.
Important Note: This method is a very rough estimate and shouldn't replace seeking professional medical advice if you suspect low oxygen levels. Symptoms such as shortness of breath, chest pain, or bluish discoloration of the skin require immediate medical attention.
Limitations of this Method
This method only assesses breathing rate, not the efficiency of oxygen uptake. Many factors influence blood oxygen levels, including lung capacity, heart function, and the presence of underlying health conditions.
Smartphone Technology (Future Possibilities)
Research is exploring using smartphone cameras and flash to measure blood oxygen levels. While not yet widely available, this technology shows promise for future at-home monitoring. See this Washington University research.
