SJN028 ~ 指夹式脉搏血氧仪 Fingertip Pulse Oximeter
🎀SJN028 ~ Fingertip Pulse Oximeter🎀
Price: RM25
🌟 Normal arterial SpO₂: 95–97%, venous SpO₂: ~75%
🌟 A pulse oximeter measures blood oxygen saturation (SpO₂), the percentage of hemoglobin bound with oxygen—covering both arterial and venous levels
🌟 Both arterial and venous oxygen come from the lungs. With normal lung function, oxygen supply is sufficient
🌟 If lung function is normal and hemoglobin levels and binding capacity are unaffected, arterial and venous SpO₂ will be adequate. Poor lung function reduces oxygen supply, lowers SpO₂, and leads to more CO₂ binding with hemoglobin, disrupting normal body functions
Additional Information:
Home-use oximeters measure arterial and venous SpO₂, which correlates with oxygen content.
Arterial: ~19.3 ml O₂/100g blood ≈ 95% SpO₂
Venous: ~12 ml O₂/100g blood ≈ 75% SpO₂
Abnormal SpO₂ often indicates low oxygen content, which may cause fatigue or drowsiness. Prolonged low oxygen can damage the brain cortex. If symptoms appear, check SpO₂ promptly and seek further evaluation.
