How Pulse Oximetry Works
Pulse oximetry is a safe and painless test used to measure the oxygen saturation levels (SpO2) and pulse rate (PR). This test measures how much oxygen there is in the patient's blood and how efficiently the oxygen is being carried to the patient's extremities. This test is fulfilled with pulse oximeter devices, which are non-invasive devices with a probe that attaches to a part of the patient's body. Typically, the probe will connect to a finger, toe, earlobe, or even head. The test is made possible with red and infrared light. One side of the probe shines red and infrared LEDs through the skin and the light is received at the other end. The ratio of red to infrared light transmitted through the blood provides the oxygen saturation measurement due to deoxygenated hemoglobin's absorption of more red light than infrared. Pulse oximeters are available if various other forms as well, such as fingertip pulse oximeters.
When to Use a Pulse Oximeter
In addition to general diagnostics and routine checks, there are a wide range of circumstances that indicate the use of pulse oximetry. Pulse oximeters are mainly used with individuals who have preexisting health conditions or are under clinical situations that may affect oxygen saturation levels.
- Routine Checks
- General Diagnostics
- Cardiac Arrest
- Any Type of COPD
- Acute Respiratory Distress Syndrome
- Endotracheal Intubation
- Sleep Apnea
- Any Other Respiratory Complaints
Frequenty Asked Questions (FAQ)
Q: What is considered to be a normal SpO2 level?
A: The level of SpO2 is dependent on the patient's circumstances. A normal level for healthy individuals is more than or equal to 95%. Normal levels for people with COPD may range from 88 to 92%. A hypoxic patient should be within 85 to 94%, while a severely hopoxic patient is considered normal at less than 85%.
Q: What are the limitations of a tabletop oximeter?
A: Pulse oximeters use red and infrared light to read SpO2 levels and pulse rate. Because of this, anything obstructing the natural pigment of the site skin may lead to an improper reading due to the obstruction absorbing the emitted light. Additionally, any exposure to bright light may negatively affect the readings. Lastly, erratic patient movement may cause the reading to be innacurate.
Q: What are the benefits of a tabletop oximeter?
A: On top of being versatile and simple to use, tabletop pulse oximeters are an efficient, non-invasive, and painless option. These devices are essential in the monitoring of certain chronic illnesses and health conditions. They can also help users keep oxygen use accurate and can help with continuing the monitoring of patients with certain sleep conditions. Pulse oximetry is common in the medical industry, making a reusable tabletop oximeter a necessary device.
