In the Keisha study, we explain the importance of measuring a service user’s oxygen saturation (blood oxygen) levels. A pulse oximeter, the tool you use to take these readings, (in the case study this was part of the WHZAN tool) is being nationally rolled out in care settings, particularly to monitor service users with suspected or identified Covid-19.
