35、 Introduction This European Standard is one of a series based on European Standard EN 60601-1 : 1990. In EN 60601-1 this type of European Standard is referred to as a Particular Standard. As stated in 1.3 of EN 60601-1 : 1990, the requirements of this European Standard take precedence over those of
36、EN 60601-1 : 1990. Clauses and subclauses additional to those in EN 60601-1 : 1990 are numbered beginning 101. Additional annexes are lettered beginning AA. Additional figures are numbered beginning 101 and additional tables are numbered beginning 101. Additional items in lettered lists are lettered
37、 beginning aa) . The measurement of carbon dioxide in a gaseous mixture has become an increasingly common practice in many areas of clinical medicine, such as anaesthesia, respiratory therapy, paediatrics and intensive care. The minimum safety requirements given in this European Standard are based o
38、n parameters that are achievable within the limits of existing technology. Annex AA contains a rationale for the most important requirements. It is included to provide additional insight into the reasoning that led to the requirements and recommendations that have been incorporated in this standard.
39、 Clauses and subclauses marked with R after their number have corresponding rationales contained in annex AA.

40、 1990 applies except that 1.1 is replaced by the following: 1.1 This European Standard specifies requirements for the safety of capnometers as defined in 3.6 of this standard. It applies to capnometers used with adults, children, and neonates. It does not apply to devices intended for use as transcu
41、taneous monitors. Capnometers intended for use in laboratory research applications are outside the scope of this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropr
42、iate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publicat
43、ion referred to applies. Appendix L of EN 60601-1 : 1990 applies with the following additions: EN 475Medical devices.

48、s approximating to the true value of the quantity measured. 3.2 alarm Signal that is activated when a monitored variable equals or crosses the alarm limit. 3.3 alarm limit Reading of a monitored variable at which the alarm is first activated. 3.4 alarm set point Setting of the adjustment control or
49、display value which indicates the monitored variables reading, at or beyond which the alarm is intended to be activated. NOTE. Terms such as alarm limits or alarm threshold are frequently used to described the same function. 3.5 alarm system Those parts of the capnometer which: a) establish the alarm limit(s); b) activate an alarm when the carbon dioxide reading is less than or equal to the low alarm set point, if provided, or is equal to or greater than the high alarm set point. 3.6 capn
