Spacelabs Healthcare is an American manufacturer of medical equipment and is a wholly owned subsidiary of OSI Systems () of Hawthorne, California and offers products and services from two divisions: patient monitoring and connectivity and diagnostic cardiology. The company headquarters are in Snoqualmie, WA and it employs over one thousand people around the world. History Spacelabs was founded in 1958 by two scientists to develop cardiac monitoring and telemetry systems for NASA to monitor astronauts' vital signs in the early space missions. They developed wireless vital signs monitoring for both Gemini and Apollo astronauts. The company went on to develop sophisticated medical monitoring systems with some significant 'firsts' resulting in them becoming one of the top US manufacturers in the 1980s. Spacelabs has had several owners. These include Squibb through Westmark, Instrumentarium Corporation and indirectly GE Medical during the GE acquisition of Instrumentarium and currently OSI Systems. Subsequently the company has made several acquisitions to expand its portfolio adding diagnostic cardiology and anesthesia products thus forming 'Spacelabs Healthcare' in 2005.
