The CO2 laser wavelength falls in the mid-infrared region of the electromagnetic spectrum. This wavelength is invisible to the human eye. Carbon dioxide laser energy is readily absorbed by water in tissue. Since soft tissue is comprised primarily of water, CO2 laser energy can be used effectively for the excision, incision, ablation, vaporization, and coagulation of soft tissue.
The laser is shipped directly from the factory to your site. Your local Lumenis representative initially uncrates, inspects, sets up and installs the laser to ensure that it is ready for use. In addition, Lumenis provides inservice training to ensure that your staff is experienced with the operation and safety considerations of the laser. Thereafter, you or the staff at your facility will perform the daily maintenance routines associated with the laser and with any delivery systems and/or accessories used during surgery, including inspecting and cleaning the laser and delivery systems; sterilizing and connecting/ disconnecting the accessories. These procedures are detailed in this manual.

Overview
AcuPulse
Most nursing staff prefer to inspect the laser and delivery systems daily, usually prior to scheduled cases and before patients are premedicated. Doing so will ensure adequate time to troubleshoot a problem or seek professional service with the least disruption to patient care. These routine tasks may be performed outside of the sterile field; in this case, ensure enough time to sterilize any components, as necessary, before scheduled cases.
1.4. Scope of This Manual
This manual is intended to provide the surgeon and other personnel who operate or maintain the system with information regarding the operating principles, controls, safety precautions, installation and maintenance of the system. While this manual is intended to aid in the in the use and care of the equipment, it does not serve as a substitute for proper training in the clinical applications of medical laser devices. This operator's manual incorporates the following chapters:

Chapter 2 Laser Safety
2.1. Introduction
Operators must take precautions to prevent exposure of laser energy to the eyes and skin from either direct or diffusely reflected laser beams, except as a therapeutic application. Additional precautions must be taken to prevent fire, electrical injury, and explosion. Lumenis does not make recommendations regarding the practice of medicine. Laser treatment parameters are provided as a guide. Individual treatment should be based on clinical training, clinical observation of laser-tissue interaction, and appropriate clinical endpoints. Patient safety should always be the clinician's first concern. This chapter of the manual includes the minimum information required to operate the system safely. In addition to the guidelines presented here, follow all applicable institutional procedures. Read this chapter completely before attempting a procedure with the AcuPulse laser system. This chapter includes:
• Basic institutional requirements, including responsibilities of the Laser Safety Officer
• How and why the laser impacts tissue, and how this is controlled • Hazards associated with unsafe laser use • Safety features of the AcuPulse • Notes, precautions, cautions and warnings associated with the AcuPulse
2.2. Training and Institutional Requirements
Caution No one should use the AcuPulse, or any other medical laser, without specific training in both medical laser use and laser safety.
Both user and safety training is available from Lumenis. Contact your Lumenis representative to inquire about seminars in your area.

Laser Safety
2.2.1. Laser Safety Guidelines
AcuPulse
American National Standards Institute specification ANSI Z136.3-2005 and Z136.1-2000 include a very thorough discussion of laser safety and guidelines for medical laser use. These standards were developed in the earliest days of lasers and are routinely revised to keep up with growing technology. ANSI Z136.3 is written specifically for the use of lasers in medicine. While non-binding, the guidelines are excellent guides for an office or institution seeking to set up a formal safety program. Lumenis strongly recommends that the operators read these two ANSI standards before using a laser in clinical practice.
2.2.2. Laser Safety Officer
Large institutions are following the prescriptions of ANSI 136.3 by setting up Laser Safety Committees and appointing Laser Safety Officers to manage laser use. Even the smallest office should have one person to act in the capacity of Laser Safety Officer. ANSI Z136.3 requires the Laser Safety Officer to fulfill the following responsibilities: 1. Classify, or verify classification of, lasers and laser systems. 2. Evaluate hazards of laser treatment areas. 3. Assure that the prescribed control measures are in effect and recommend or approve alternates when the primary ones are not feasible. 4. Approve operational procedures, including any procedural checklists. 5. Recommend or approve protective equipment, and assure that it is periodically inspected to ensure proper working order. 6. Approve wording on signs and equipment labels. 7. Approve installation and equipment prior to use, and modifications to existing equipment and facilities. 8. Assure adequate safety education and training is provided for all personnel. The Laser Safety Officer may also assume other responsibilities, such keeping laser use and maintenance logs. The Laser Safety Officer should become familiar with the periodic maintenance requirements in the Maintenance chapter of this manual.

AcuPulse
2.2.3. Laser Treatment/ Operating Area
Laser Safety
According to ANSI Z136.3, the Laser Safety Officer is responsible for the area in which laser treatments are carried out. In meeting this requirement, the Laser Safety Officer should ensure that: 1. The surroundings are safe for both the patient and the operator. 2. The floor is uncluttered and clear access is maintained to the footswitch. Cables are secure and not crimped. 3. The operating area is occupied only by authorized personnel. 4. Appropriate warning signs are posted in the operating area and just outside of it. The AcuPulse is a Class IV laser; the door warning sign for the AcuPulse is shown in Figure 2-1.

2.3. Understanding and Controlling Laser Impact on Tissue
AcuPulse
Warning The AcuPulse system contains a Class IV, CO2 laser which produces an invisible beam of high energy infrared radiation. Improper use could result in serious personal injury. Observe all safety precautions for Class IV lasers.
Many different types of lasers have been developed for multitudes of different uses. Each type of laser has a certain potential for harm if misused. Even lasers designed for use on living tissue must be used and applied carefully in order to avoid:
• Hazards to the patient or clinical personnel • Hazards to the physical surroundings For this reason, it is important to understand the basics of how laser energy affects living tissue and how to control this energy so as to avoid misapplication. The tissue damage that a misused laser may do depends on the following factors:
• Class of the laser • Wavelength of the laser • Tissue variability of the area in contact with a laser beam • Spot size or beam diameter • Power • Exposure, or time duration of beam contact The following sections describe these factors in more detail.
