Pulse Oximeter
Introduction It is a mechanical device used to measure the oxygen saturation in the body which means the amount of hemoglobin in the blood carrying the oxygen
•Normal saturation is 95-100 in adults •<94 considered as abnormal •<90 is worrying issue

Working Principle It has red (R) and Infrared (IR) light emitting LED’s and a photo detector. Oxygenated hemoglobin absorbs more IR light and Deoxygenated hemoglobin absorbs more red light.
Calculation of O2 Saturation Saturation= C (HbO2) 100 C (HbO2)+C(Hb)

Uses 1. Used in Operation Room 2. ICU 3. Wards 4. Emergency department 5. Cardiac catheterization units 6. Delivery rooms
Common Factors affecting measurement of oxygen saturation 1. Blood pressure less than 80 mmhg is difficult to assess (should always be more than 80mmhg) 2. Vascular impingement 3. AV fistula 4. Compression by the probe 5. Cardiac arrest 6. Heart rate extremes (> 200 or <30)
Specific Factors affecting measurement of oxygen saturation Falsely High SPO2 • presence of abnormal Hb • Anemia (<10) Falsely Low SPO2 • High venous pressure (CCF) • Use of nail polish • Skin colour
Technical factors • Problem with sensing • Low flow states • Ambient light
