Benefits of Pulse Oximetry vs Arterial Blood Gas in Small Animal Research

Blood gas and pulse oximetry are two types of measurements that provide insight into blood gas exchange.  There are significant differences in how each is measured.  Blood gases are measured by removal of a small sample of blood, which is then delivered into a device that measures parameters directly from the blood.  Blood gas machines conduct […]

Animal Monitoring in the Laboratory with Pulse Oximetry

Several types of pulse oximeters were developed in the mid 1900’s, but the modern version used throughout hospitals today was invented in 1972. In 1980, modern pulse oximetry was first commercialized, making it readily available – it quickly grew in popularity. Because of its ease-of-use, low cost and non-invasive nature, pulse oximetry is mandated in […]
