Pulse oximetry is a non-invasive method employed by medical professionals to monitor a person's oxygen saturation level. In its simplistic form, a pulse oximeter is a small device that clips onto a patient's finger, toe, or earlobe. It operates on the principle of spectrophotometry, emitting light of two different wavelengths into the body part it is attached to. The device then measures the light absorption of oxygenated and deoxygenated blood, thereby providing an estimate of oxygen saturation.
This portable device is particularly useful in EMS (Emergency Medical Services) settings where real-time, dynamic patient information is required for immediate clinical decision-making. In the next section, we will discuss what the data from pulse oximetry means and why it's essential in EMS.
The What: Interpreting the Readings
The display from a pulse oximeter reads something like “93% SpO2 (oxygen saturation)”. This number is an estimate of how much oxygenated hemoglobin is in the patient’s blood, relative to the total amount of hemoglobin present. A healthy person typically has an oxygen saturation of 97-99%, while a low reading could be indicative of conditions such as pulmonary diseases, cardiac diseases, and anemia.
In an EMS setting, the use of pulse oximetry can help clinicians diagnose and treat a range of medical conditions quicker than before. By taking readings during transport or in the ambulance, it provides clinicians with real-time data that can help them make informed decisions quickly.
The Why: Clinical Significance of Pulse Oximetry
In the past, oximetry was used mostly in hospitals to monitor patients who were already ill or had undergone a surgical procedure. However, with the advent of portable pulse oximeters, EMS clinicians can now get real-time data on a person’s oxygen saturation level and adjust their treatment accordingly. This has led to improved patient outcomes and reduced time spent in the hospital.
Pulse oximetry is also useful for patients with chronic conditions such as asthma or COPD (chronic obstructive pulmonary disease). With regular monitoring, EMS professionals can identify early signs of exacerbation or deterioration and take appropriate action.
The use of pulse oximetry is especially important in the early detection of hypoxia, a condition characterized by inadequate oxygen supply to tissue. Early detection and treatment can reduce the risks associated with prolonged hypoxia, which includes damage to organs such as the brain, heart, and lungs.
Conclusion
Pulse oximetry is an essential tool in the arsenal of EMS professionals. The data provided by a portable pulse oximeter can help clinicians diagnose and treat medical conditions quickly and accurately, leading to better patient outcomes. Furthermore, with regular monitoring of oxygen saturation levels, it can also enable early detection of hypoxia and other serious conditions.
