1. Pulse oximetry

2. Pulse oximeters measure how much of the hemoglobin in blood is carrying oxygen (oxygen saturation). Pulse oximeters are in common use because they are: Non invasive Cheap to buy and use Can be very compact Detects hypoxemia earlier than you using your eyes to see cyanosis. Oxygen is carried in our blood is by means of hemoglobin. INTRODUCTION

3. Pulse oximetry uses light to measure oxygen saturation. Light beams go through your finger into a light detector on the other side of the pulse oximeter. Some of the light beams will make it through the finger, while others will absorb into the finger. The amount of light that the finger absorbs depends on several factors: The concentration of the substance that’s in between the light beams and the light detector. The length of the light path in that substance. The amount of oxygenated hemoglobin. The amount of deoxygenation hemoglobin. HOW A PULSE OXIMETER WORKS?

4. TYPES There are six main types of pulse oximeters: Fingertip Handheld Benchtop Phone-based Wearable (e.g. watches) Multimodal (e.g. integrated into other types of monitors)

5. PURPOSE Purpose of pulse oximeter Measures the arterial oxygen saturation of hemoglobin. To relieve cyanosis by detecting hypoxia and severe respiratory failure. Access the effectiveness of oxygen administration.

6. When do you need pulse oximetry? If you have hypoxia If you have respiratory complaints In order to monitor oxygen levels To monitor the effectiveness of oxygen therapy If you have sleep apnea If you are sedated If you are hemodynamically unstable INDICATIONS

7. Contraindications of pulse oximetry: Intravenous dyes Skin pigmentation External interference Nail painting/polish Irregular signals Hemoglobin deficiency Carbon monoxide Blood volume deficiency CONTRAINDICATIONS

8. Pulse oximeters measure blood oxygen levels and heart rate. They're used for: Medical Monitoring: In hospitals, clinics, and homes for patients with respiratory issues. Physical Activity: Athletes track oxygen levels during workouts. High Altitude: Travelers monitor oxygen in high-altitude areas. Sleep Apnea: Diagnosing and managing sleep disorders. Chronic Conditions: Tracking health over time. Home Monitoring: Periodic health checks at home. COVID-19 Monitoring: Monitoring respiratory health, especially during the pandemic USES

9. Generally we measured on various sites like: Fingers Nose Toes Ear (Pinna) Forehead Infants Sole Palm Big toe or thumb. LOCATIONS

10. The pulse oximeter gives inaccurate reading in following conditions: Cyanosis Anemia Incorrect placement Abnormal hemoglobin Poor peripheral perfusion Movement Colored dyes Optical shunting Room light Injury or infection Calibration FALSE READING
