Bibliography

This Part of CEN/TS 14507 refers to EN 60601 1:1990 "Medical electrical equipment - Part 1: General requirements for safety", as amended by its amendments 1 (1991) and 2 (1995). For brevity Part 1 is referred to in this Part of CEN/TS 14507 either as the General Standard or as the General requirements. The scope given in clause 1 of the General Standard applies except that 1.1 is replaced by the following: 1.1This Part of CEN/TS 14507 specifies particular requirements for inhalational nitric oxide delivery systems and their modules. It covers devices which can be supplied in combined units, integrated into another medical device, for example a lung ventilator, or as individual devices. This Part of CEN/TS 14507 addresses the monitoring of nitric oxide and oxygen delivery to the patient and minimization of the production of nitrogen dioxide. This Part of CEN/TS 14507 covers the requirements for inhalational nitric oxide delivery systems intended for medical use, for example, in critical care, anaesthesia, and emergency/transport environments.NOTEIt is recognized that from time to time innovations and designs will appear that offer advantages and yet are not covered by specific safety-related design or performance aspects of this Part of CEN/TS 14507; such innovations are not to be discouraged. As the techniques and technologies in these innovations advance, it is essential that the safety objectives of this Part of CEN/TS 14507 are considered as minimum requirements.The requirements of clause 1.3 of the General Standard apply with the following additions:The numbering of clauses and subclauses of this Part of CEN/TS 14507 corresponds to that of the General Standard. The changes to the text of the General Standard are specified by the use of the following words: ´Replacement´ means that the clause or subclause of the General Standard is replaced completely by the text of this Part of CEN/TS 14507.(...)
