Laboratory work for intensive care unit (ICU) patients can be laborious, time-consuming and repetitive for providers, as well as painful, draining and tedious for patients who are already among the sickest in the hospital. Hayward, Calif.-based startup Optiscan Biomedical Corp. aims to enable continuous, blood-based patient monitoring in the ICU that alerts care providers when vital measures stray out of range. Patients who remain in-range on these indicators have been shown to have fewer complications, shorter hospital stays and reduced costs.
