1、Designation:F 1415 92(Reapproved 2000)Standard Specification forPulse Oximeters1This standard is issued under the fixed designation F 1415;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parenthe
2、ses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe approximation of hemoglobin saturation through the use of pulse oximetry has become anincreasingly common practice in many areas of clinical medicine.T
3、hese areas include,but are notlimited to anesthesia,respiratory therapy,pediatrics,and intensive care.A variety of devices arecurrently available that are intended for these applications.This specification covers minimum safetyand performance requirements based on parameters that are believed to be
4、achievable within the limitsof existing technology.Appendix X1 contains a rationale for the most important requirements.It is included to provideadditional insight into the reasoning that led to the requirements and recommendations that have beenincorporated in this specification.This specification
5、references IEC 601-1 for many of the general requirements for safety.Requirements specific to pulse oximeters not included in IEC 601-1.1.Scope1.1 The scope given in Clause 1 of IEC 601-1 applies exceptthat 1.1 shall be replaced by the following:1.1.1 This specification includes requirements for the
6、 safetyand performance of pulse oximeters,as defined in 3.2.9intended for use in approximating the saturation of arterialhemoglobin,non-invasively,from a light signal transmittedthrough the tissue,taking into account the pulsatile nature ofvolume changes with blood flow.1.2 The field of application
7、includes,but is not limited to:intraoperative and perioperative use;adult critical care appli-cation;pediatric and neonatal application;and general deter-mination of saturation on hospitalized and non-hospitalizedpatients.1.3 Pulse oximeters intended for use in laboratory researchapplications and“be
8、nch”type oximeters that require a bloodsample from the patient are outside the scope of this specifi-cation.2.Referenced Documents2.1 The following standards contain provisions that,through reference in this text,constitute provisions of thisspecification.At the time of publication,the editions indi
