Aneroid sphygmomanometers. An assessment of accuracy at a university hospital and clinics

Progestogen-only pills (POPs) and body weight

“…Moderate cervical traction straightens the uterus and the routine use of a tenaculum theoretically makes insertion of an IUD safer. 3 This study confirms my personal experience. Even though the GyneFix inserter tube is quite stiff, insertion up to the fundus is easy, as long as sufficient traction is exerted on the cervix.…”

“…The authors provided no justification on the grounds of accuracy for their decision to change mercury devices for aneroid devices. Indeed, there have been many reports of aneroid device inaccuracy, 3 and when we performed a similar study that included both site inspection and validation studies on all the devices within a large maternity hospital, we found aneroid devices to be surprisingly inaccurate. Of 39 aneroid and 36 mercury sphygmomanometers, 31 (86%) of the mercury devices and 36 (92%) of the aneroid devices were in adequate working condition and suitable for analysis.…”

“…I was puzzled by the letter from Cooper. 3 If injectable contraceptives are less effective in underweight patients, why give double dose DMPA to overweight patients? I followed up the reference to Guillebaud's book and found that he was quoting Sapire.…”

“…As the GyneFix is frameless and flexible, it is unlikely that the device is forced through the uterine wall by uterine contractions, as is suspected with framed IUDs reported by Tatum (the inventor of the T-shaped IUD) and Connell. 3 In their review article, published in 1989, they make the following comments about perforation: 'The incidence of this complication ranges from 0.0 to 8. 7 …”

“…8 However, the aneroid sphygmomanometers could likewise be unreliable and operator-dependent and were discovered to be inaccurate in 80% of the units assessed at a university hospital and clinic. 9 Several reports now showed that the average difference between the results of daytime ABPM and HBPM was -1.7/1.2 mmHg, which was not clinically important. [10][11][12][13] With the establishment of strict accuracy standards by the Association for the Advancement of Medical Instrumentation (AAMI) 14 and that of the British Hypertension Society, 15 reports confirming accuracy were published 16,17 and public buying AAMI and BHS certified devices could be assured of reliability of the monitors.…”
