Henry Heimlich choking-rescue guidelines of the American Heart Association and of the American Red Cross taught rescuers to first perform a series of backblows to remove the FBAO (foreign body airway obstruction); if backblows failed, then rescuers learned to proceed with the Heimlich maneuver (aka "abdominal thrusts"). After a July 1985 American Heart Association conference, backblows were removed from choking-rescue guidelines. From 1986 to 2005, the published guidelines of the American Heart Association and the American Red Cross recommended only the Heimlich maneuver as the treatment for choking; the National Institutes of Health still does apply it for conscious persons over one
Remote procedure call invocation. RMIs in turn fell in popularity with the rise of the internet, particularly in the 2000s. Remote procedure calls used in modern operating systems trace their roots back to the RC 4000 multiprogramming system, which used a request-response communication protocol for process synchronization. The idea of treating network operations as remote procedure calls goes back at least to the 1970s in early ARPANET documents. In 1978, Per Brinch Hansen proposed Distributed Processes, a language for distributed computing based on "external requests" consisting of procedure calls between processes. Bruce Jay Nelson is generally credited with coining the term "remote procedure
