31、nitions given in EN 10601:1995 and EN 10603:1997 and the following apply. 3.1 neonatal mode mode, specified by the manufacturer of the sphygmomanometer for the measurement of neonates/infants 3.2 paired measurements parallel blood pressure measurements carried out by the observers and the device und

EN 1060-4:2004 (E) 6 4 Requirements 4.1 General information on the non-invasive reference methods The clinical i

33、nvestigation shall be performed in accordance with EN ISO 141551 and EN ISO 141552. The auscultatory blood pressure measurements described shall be carried out by two observers by means of a double stethoscope. The auscultatory reference value will then be the mean value of the two values determined

34、 by the observers. The difference between both values shall not exceed 4 mmHg. Any measurements with observer-to- observer differences greater than 4 mmHg shall not be included in the data set. The number of discarded measurements shall not be greater than the number of the required valid measuremen

35、ts. NOTE 1 Reading of the values on the reference manometer should be as accurate as possible. When reading the value on the reference manometer(s) the observers should avoid parallax errors. Rounding to zero and five has a negative effect on the result of the investigation. More information and rec

36、ommendations are given in annex D. The calibrated reference manometers shall comply with the requirements of EN 1060-1 to EN 1060-3 but shall not exceed error limits of 1 mmHg (0,1 kPa) with dropping cuff pressure prior to the start of the clinical investigation. NOTE 2 The reference manometer shoul

37、d be calibrated before and after the clinical investigation. When the reference manometer is linked to the pneumatic system of the tested device (e.g. test method N2), an aneroid manometer should be used. Mercury manometer may alter pneumatic characteristics (resonant frequency, damping coefficient)

38、 and should not be used in this case. 4.2 General information on the invasive reference methods The clinical investigation shall be performed in accordance with EN ISO 141551 and EN ISO 141552. The invasive blood pressure measuring system consisting of catheter, pressure transducer, monitor and reco

39、rding device shall be statically calibrated so that the indicated values do not deviate from the values indicated by the reference manometer (see 4.5.1.1 a) by more than 2 mmHg. Prior to and after each series of measurements the resonant frequency and damping coefficient of the system shall be deter

40、mined 1. Except for devices measuring in the neonatal mode, the comparison shall be carried out by invasive and non- invasive blood pressure measurement on the same arm. The simultaneous measurement on opposite arms is permissible if no lateral difference has been determined by additional measuremen

41、ts. NOTE Intra-arterial methods are invasive and should not be used for patients or subjects solely for the purpose of validating instrument performance, but conducted on clinical patients in whom an intra-arterial line has already been placed for reasons other than sphygmomanometer verification. 4.

42、3 Selection of clinical test method The selection of the clinical test method is dependent on the measurement technique, the application of the sphygmomanometers to be tested and the intended application of the device and shall be in accordance with Table 1.
