One of the most important measurements a first responder can take in a conscious person is the oxygen saturation in their blood. Fast, painless and noninvasive, this simple test can reveal a lot about a person’s condition in the first few seconds of assessment. Designed to measure the oxygen levels in the parts farthest from the heart a pulse oximeter is clipped onto the finger, toe or earlobe of the person in question. This painless clip contains an infrared light on one side and a light sensor on the other. Let’s assume the pulse oximeter is clipped onto a finger. Light is projected through the skin, soft tissue and bone of the finger and received by the sensor on the other side. Judging by how well the light is received on the other side, the pulse oximeter can measure the amount of hemoglobin in the blood and translate that into an oxygen saturation level.
While many larger monitoring systems include a built-in pulse oximeter, stand-alone systems are ideal for clinical and emergency applications. These devices are small, lightweight, easy-to-carry, and simple to use. However, they are also fragile pieces of medical equipment. When simply left in a drawer or cupboard without a protective case, they are prone to shorts in the cord, damage to buttons and display screens and breaks in the case of the device. This is why, like smartphones and laptops, pulse oximeters need a carrying case. From water resistant cases to bags with straps for easy carrying, pulse oximeter cases come in every shape and size for every device and situation. Some even come with a convenient belt for handy carrying when you need both hands free.
If you invest in a piece of medical equipment, why not invest in a protective carrying case to go with it?
