Ever wondered what that SpO2 reading at the doctor's office means? It's short for peripheral capillary oxygen saturation, and it essentially tells you how much oxygen your red blood cells are carrying. Knowing your oxygen levels is crucial for understanding your overall health.
A healthy SpO2 reading typically falls between 95% and 100%. Readings below 90% are considered low (hypoxemia) and may indicate an underlying respiratory or circulatory issue. Conditions like asthma, COPD, pneumonia, and even heart problems can affect your oxygen saturation.
Factors like altitude, age, and pre-existing medical conditions can influence what's considered 'normal' for you. While home pulse oximeters can be helpful, they're not a substitute for professional medical advice. If you're concerned about your oxygen levels, especially if you experience shortness of breath, chest pain, or dizziness, consult your doctor immediately. Understanding your SpO2 is the first step towards proactive health management!
