In EN 60601-1 this type of European Standard is referred to as a Particular Standard. As
34、stated in 1.3 of EN 60601-1 : 1990, the requirements of this European Standard take precedence over those of 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 items in lettered lists
35、 are lettered beginning aa). The approximate measurement of haemoglobin saturation through the use of pulse oximetry has become an increasingly common practice in many areas of clinical medicine, such as anaesthesia, respiratory therapy, paediatrics, and intensive care. The minimum safety requiremen
36、ts given in this European Standard are based on 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
37、 that have been incorporated in this standard. Clauses and subclauses marked with R after their number have corresponding rationales contained in annex AA.

38、 one. General 1 Scope Clause 1 of EN 60601-1 : 1990 applies except that 1.1 is replaced by the following: 1.1 This European Standard specifies requirements for the safety of pulse oximeters, as defined in 3.12 of this standard, intended for use in the approximate measurement of the saturation of hum
39、an arterial haemoglobin, non-invasively. The field of application includes, but is not limited to: a) perioperative use; b) adult critical care application; c) paediatric and neonatal applications; d) general determination of saturation on hospitalized and non-hospitalized patients. Pulse oximeters
40、intended for use in laboratory research applications and bench type oximeters that require a blood sample from the patient are outside the scope of this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These norma
41、tive references are cited at the appropriate 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 refer
42、ences the latest edition of the publication referred to applies: Annex L of EN 60601 : 1990 applies with the following additions: EN 475Medical devices Electrically-generated alarm signals EN 60601-1 : 1990Medical electrical equipment Part 1: General requirements for safety (IEC 601-1:1988) EN 60601

44、mpatibility for industrial-process measurement and control equipment Part 2: Electrostatic discharge requirements 3 Terminology and definitions For the purposes of this standard, clause 2 of EN 60601-1 : 1990 applies with the following additions. 3.1 alarm Signal that is activated when a monitored v
45、ariable equals or crosses the alarm limit. 3.2 alarm set point Setting of the adjustment control or display value which indicates the SpO2reading, at or beyond which the alarm is intended to be activated. NOTE. Terms such as alarm limits or alarm threshold are frequently used to describe the same fu
46、nction. 3.3 alarm system Those parts of the pulse oximeter which: a) establish the alarm set point(s); b) activate an alarm when the SpO2is less than or equal to the low alarm set point or is equal to or greater than the high alarm set point. 3.4 calibration range Range over which SpO2values have be
47、en calibrated and validated by appropriate in vivo or in vitro methods. 3.5 default setting; default limits Parameters first active on power up of the device. 3.6 display range Range of SpO2values indicated by the pulse oximeter. 3.7 display update period Intervals between updates of the displayed v
48、alues. 3.8 fractional saturation That saturation given by the oxyhaemoglobin (O2Hb) divided by the total haemoglobin (Hbtotal), represented mathematically as: O2Hb Hbtotal 3.9 functional saturation That saturation given by the oxyhaemoglobin divided by the sum of the oxyhaemoglobin and the deoxyhaem
49、oglobin (HHb), represented mathematically as: O2Hb (02Hb + HHb) 3.10 probe Part of the pulse oximeter intended to sense the signal from the patient from which the SpO2is derived. 3.11 probe fault Condition including, but not limited to a probe component failure or the disconnection of the probe from either the pulse oximeter, or from the patient.
