Robotic surgery, computer-assisted surgery, and robot-assisted surgery are terms for various technological developments that currently are developed to support a range of surgical procedures.

Robot-assisted surgery was developed to overcome limitations of minimally invasive surgery. Instead of directly moving the instruments the surgeon uses a computer console to manipulate the instruments attached to multiple robot arms. The computer translates the surgeon’s movements, which are then carried out on the patient by the robot. Other features of the robotic system include, for example, an integrated tremor filter and the ability for scaling of movements (changing of the ratio between the extent of movements at the master console to the internal movements of the instruments attached to the robot). The console is located in the same operating room as the patient, but physically separated from the operative workspace, or in another place. Since the surgeon does not need to be in the immediate location of the patient while the operation is being performed, it can be possible for specialists to perform remote surgery on patients. Robots can also perform surgery without a human surgeon.

Life Support[]

"The following definition appears in the glossary of the JCAHO 2009 Comprehensive Accreditation Manual:

Life Support Equipment: Any device used for the purpose of sustaining life and whose failure to perform its primary function, when used according to manufacturer’s instructions and clinical protocol, will lead to patient death in the absence of immediate intervention (examples include ventilators, heart-lung bypass machines).

Defibrillation is a response to life-threatening cardiac arrhythmias, ventricular fibrillation and ventricular tachycardia. Defibrillation consists of delivering a therapeutic dose of electricity to the affected heart with a defibrillator. The dose of electricity restores a normal heart rhythm, allowing the heart to continue to function in the patient. Therefore, the Joint Commission considers defibrillators life support equipment.

As it is required that organizations maintain an inventory of all medical equipment or selected medical equipment categorized by physical risk associated with use (including all life support equipment), defibrillators must be included in an organization's medical equipment inventory.

Maintenance activities then must be identified for equipment on the inventory. A maintenance strategy for defibrillators could include a range of activities from a visual inspection of the single-use AED (automatic external defibrillator) to the daily testing of a defibrillator in clinical use settings based on organization policy."[1]
