چکیده

To the Editor: Myers et al.1 in their article “Comparison Between an Automated and Manual Sphygmomanometer in a Population Survey” compared blood pressures (BPs) measured with a standard mercury sphygmomanometer and an oscillometric sphygmomanometer and concluded that “conventional manual BP readings taken using mercury sphygmomanometry can be replaced by (readings taken using) a validated, automated recorder”. We contend that this conclusion is not supported by their study, which is invalid for four reasons.

Validity of Selected WBC Differentiation Flags in Sysmex XT-1800i

Background: Automatic Cell Counter devises make the CBC differential very easy and delivering the results in few second. However, the problem with this device is facing a flag requires a time-consuming microscopic review of the specimen which causes unacceptable wait times for patient as well as costs for laboratories. In this study, we calculated the validity of WBC d...

Hematopathology / ELIMINATION OF REFLEX MANUAL DIFFERENTIAL COUNTS

Automated peripheral blood leukocyte differential counts (LDCs) are widely accepted in routine practice. However, many laboratories still reflexively perform manual LDCs based solely on abnormal automated results or instrument “flags,” before any manual triage step. We describe our transition to a procedure that uses manual methods to validate, rather than to replace, automated LDCs (an approac...

Defects in sphygmomanometers: an important source of error in blood pressure recording.

Almost half the sphygmomanometers in a teaching hospital group had defects in the control valve which interfered with accurate blood-pressure reading. Ward staff should be taught to check sphygmomanometers regularly and replace control valves; time consumption and cost are low. The cuffs in general use in these hospitals, and of the standard size sold in Britain, had rubber bags which did not e...

Ambulatory blood pressure monitoring evaluation of a semi-automated device.

The accuracy of a semi-automated ambulatory blood pressure monitoring device (the Instrumedix 'Personal Blood Pressure Transmitter') was assessed in 36 patients undergoing diagnostic cardiac catheterisation. Blood pressure readings measured by the device and by a standard manual sphygmomanometer were compared with simultaneous intra-aortic pressure measured directly via the catheter. No measure...

مقایسه شمارش خودکار با شمارش دستی نوتروفیل‌ها در تشخیص پریتونیت باکتریال خود به خودی

Introduction: Spontaneous bacterial peritonitis (SBP) is a prevalent complication in the patients with cirrhosis and ascites, which leads to high intrahospital mortality. Diagnosis is made when ascetic fluid neutrophils is ≥250 cells/mm3. Manual counting of neutrophils is time-consuming, technically difficult, expensive and in many cases individual-dependent. In contrast, automated counting ...
