STAFF Normal medical department staffing is four staff physicians (of which at least one must have training in emergency medicine), three medical technicians, and twelve registered nurses. Normal on-duty medical complement for first and second shifts is one staff physician, two nurses, and one medical technician. During the night shift, normal staffing drops to two nurses. These staffing figures are subject to upward adjustment, depending on patient load. In emergency situations, cross-trained personnel from other departments can be made available for medical duty. Approximately 40% of all crew personnel are cross-trained for various secondary medical functions. A staff of eight to twelve additional research and laboratory personnel are also attached to the medical department. These individuals are typically attached to various research projects, but are available to assist with medical lab assignments on a priority basis as needed. Æ
