19、amendment A1:2006 (+ corrigendum October 2006).This European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 93/42/EEC. See Annex ZZ. This European Standard constitutes a

20、collateral standard to EN 60601-1:2006, hereafter referred to as the general standard. This EN 60601-1-8 was revised to structurally align it with EN 60601-1:2006 and to implement the decision of IEC SC 62A that the clause numbering structure of collateral standards written to EN 60601-1:2006 would

21、adhere to the form specified in ISO/IEC Directives, Part 2:2004. The principle technical changes are in Clause 4, which now recognizes that there is a general requirement for a risk management process in EN 60601-1:2006. In the 60601 series of publications, collateral standards specify general requi

22、rements for safety applicable to a subgroup of MEDICAL ELECTRICAL EQUIPMENT (e.g. radiological equipment); or a specific characteristic of all MEDICAL ELECTRICAL EQUIPMENT, not fully addressed in the general standard (e.g. alarm systems). In this collateral standard the following print types are use

23、d: requirements and definitions: in roman type; test specifications: in italic type. In addition, in Annex A text in italics indicates guidance that describes means to achieve the safety objectives of this collateral standard; informative material appearing outside of tables, such as notes, examples

24、 and references: in smaller type. Normative text of tables is also in a smaller type; TERMS DEFINED IN CLAUSE 3 OF THE GENERAL STANDARD, IN THIS COLLATERAL STANDARD OR AS NOTES: IN SMALL CAPITALS. In referring to the structure of this standard, the term “clause” means one of the six numbered divisio

25、ns within the table of contents, inclusive of all subdivisions (e.g. Clause 6 includes Subclauses 6.1, 6.2, etc.); “subclause” means a numbered subdivision of a clause (e.g. 6.1, 6.2 and 6.2.1 are all subclauses of Clause 6). latest date by which the national standards conflicting with the EN have t

References to subclauses within this standard are by number only. In this standard, the conjunctive

27、“or” is used as an “inclusive or” so a statement is true if any combination of the conditions is true. The verbal forms used in this standard conform to usage described in Annex H of the ISO/IEC Directives, Part 2. For the purposes of this standard, the auxiliary verb “shall” means that compliance w

28、ith a requirement or a test is mandatory for compliance with this standard; “should” means that compliance with a requirement or a test is recommended but is not mandatory for compliance with this standard; “may” is used to describe a permissible way to achieve compliance with a requirement or test.

ALA

43、RM SIGNALS are frequently used to indicate unsatisfactory physiological PATIENT states, unsatisfactory functional states of the MEDICAL ELECTRICAL EQUIPMENT or MEDICAL ELECTRICAL SYSTEM or to warn the OPERATOR of HAZARDS to the PATIENT or OPERATOR due to the MEDICAL ELECTRICAL EQUIPMENT or MEDICAL E

44、LECTRICAL SYSTEM. INFORMATION SIGNALS convey information that is independent of an ALARM CONDITION. Surveys of healthcare personnel have indicated significant discontent with ALARM SIGNALS. Problems include difficulty in identifying the source of an ALARM SIGNAL, loud and distracting ALARM SIGNALS,

45、and the high incidence of FALSE POSITIVE or NEGATIVE ALARM CONDITIONS 161). Surveys of MANUFACTURERS of medical monitors demonstrated a wide variety of DEFAULT ALARM PRESETS. The leading reason for disabling ALARM SIGNALS is the large number of ALARM SIGNALS associated with FALSE POSITIVE ALARM COND

46、ITIONS. See also bibliography. Safety of PATIENTS depends on the ability of the OPERATOR to correctly discern the characteristics of ALARM SIGNALS. USABILITY is an important element in the design of ALARM SIGNALS that are readily discernible without being unnecessarily distracting or disturbing. Thi

47、s approach is intended to rationalize the current situation, to reduce confusion by limiting proliferation of ALARM SIGNALS and their control states, and to minimize distraction for other people. This collateral standard was developed with contributions from clinicians, engineers and applied psychol

48、ogists. The terminology, requirements, general recommendations and guidance of this collateral standard are intended to be useful for MANUFACTURERS of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS and for technical committees responsible for particular standards. The effectiveness of a

49、ny ALARM SYSTEM depends critically on its implementation by the RESPONSIBLE ORGANIZATION. It is important that the RESPONSIBLE ORGANIZATION configure the ALARM SYSTEM so that an OPERATOR is not able to compromise it. 1) Figures in brackets refer to the bibliography. 6 BS EN 60601-1-8:2007+A1:2013 EN 60601-1-8:2007+A1:2013 (E)MEDICAL ELECTRICAL EQUIPMENT Part 1-8: General requirements for basic safety and essential p
