*5.2.5 Use of restraints*

Airway management is made possible during spaceflight using restraints, allowing the operator's hands to be free to hold and guide the endotracheal tube into the airway [38]. Use of restraints are absolutely necessary to hold instruments, patients and personnel in place. For surgical procedures, it has been demonstrated that it is possible to restrain instruments in microgravity using various supplies ensuring sterility, operator accessibility, safe waste disposal, while maintaining ergonomic capability [48, 49].
