Complications from utilizing a pulse oximeter are rare. However, it is critical to concentrate on the probe site as blisters or nail damage may occur with extended use. Tissue harm might also occur within the setting of incompatible probes or throughout a substitution within the type of electrical shock or burns. Additionally it is important to know the way to enhance the measurements of pulse oximeters. One significant threat of utilizing a pulse oximeter is the potential of treating an incorrect reading as correct. False-destructive results for hypoxemia and false-positive results for normoxemia or hypoxemia can happen. In these conditions, a affected person might obtain inappropriate therapy, leading to harm. False regular or high readings can occur in a number of totally different settings. Carboxyhemoglobin absorbs mild at 660 nanometers, roughly the identical as oxyhemoglobin. Thus, in conditions where carboxyhemoglobin is high, a false regular reading might occur. When glycohemoglobin A1c levels are greater than 7%, resembling in patients with kind 2 diabetes, arterial oxygen saturation could also be overestimated. These conditions may require an arterial blood gasoline to find out oxygen saturation precisely. It's also mandatory to contemplate the clinical analysis when evaluating a patient with hypoxemic symptoms, as within the case of carbon monoxide toxicity. False low readings may occur in a number of settings. Below are some situations that will cause falsely low readings to happen.
