Are you planning to purchase a durasensor? You can find them at various sites such as euroenergy.co.uk. It’s helpful to know how the units work so you can pick the right one for your needs and understand the basic mechanics of the device.
A pulse oximeter measures the quantity of hemoglobin contained in blood is holding oxygen. This is also known as “oxygen saturation.” These devices are actually quite common in the healthcare industry. They’re found in various places including operation rooms, critical care, recovery, ambulances, wards, and so on.
Durasensors are common for various reasons. /For example, they’re:
- Detect hypoxemia fast
These are some of the key benefits of using oximeters. In many cases, they’re more effective than other methods. For example, they can detect hypoxemia better than visual detection. This is important because it can help to prevent emergency situations with the patient.
It’s important to know the basics about “oxygen saturation.” A pulse oximeter measures oxygen saturation, which is a key factor in learning how oximeters work. Oxygen is critical for life so when people have various lung conditions like COPD and asthma it’s important to know when this figure is too low. As a general rule, the oxygen saturation level should always be above 90%.
Oxygen enters a person’s lungs then passes into their blood. Next, the blood transports the oxygen to the body’s different organs. The main way oxygen is transported in the blood is through hemoglobin. One way to think of hemoglobin molecules is as “cars” and the vehicles’ “roads” being human blood vessels. So in a sense, the molecules of oxygen climb into the cars then travel around the body until they arrive at their final destination.
The hemoglobin that lacks oxygen is called “de-oxygenated hemoglobin.” Meanwhile, the hemoglobin that contains oxygen is called oxygenated hemoglobin. Oxygen saturation is just the percentage of hemoglobin that’s available to carry oxygen. The percentage of hemoglobin units can range from 0% to 100%.So the oxygen saturation levels reveal the percentage of the person’s total hemoglobin that’s carrying oxygen.
Another important term to be familiar with is “pulse oximetry.” This is the process of using light to calculate oxygen saturation. Light sources emit light. It then moves across the pulse oximeter probe, then gets to the light detector.
The amount of light that the finger absorbs is based on various physical properties. The pulse oximeter uses the properties to determine the person’s oxygen saturation. Meanwhile, the quantity of light that’s absorbed is based on various factors.
The device includes light sensors that emit light. They’re located above the finger. An artery is located in the finger’s artery that transports blood. The artery carries blood that the oximeter reads. There’s also a vein where the blood exits the finger.
Another important issue is that an oximeter uses Beer’s Law and Lambert’s Law. The problem is that these laws have strict rules in physics to be very accurate. For example, blood contains various irregular items including red cells. This causes light to scatter. As a result, the durasensors must be calibrated.
