“…Recent studies have in fact shown that the correlation between SpHb and LHb is reduced in patients with significant haemorrhage or at risk of haemorrhage [4,25,35]. In contrast, other studies have found that significant intraoperative haemorrhage or controlled hypotensive anaesthesia have no major effect on SpHb [36,37]. Further work is needed to clarify the possible role of these factors.…”

Background: The accuracy and reliability of non-invasive oximetry for haemoglobin measurements were reported in operating rooms and intensive care units, though few studies evaluated this technology in emergency departments. The purpose of this study was to evaluate the accuracy and reliability of non-invasive SpHb readings from a portable device, in emergency department patients, compared to synchronous LabHb measurements. The authors sought to minimise external variables that could influence device performance, including learning curves and patient conditions, thus performed measurements by one trained user on stable adults only.

“…In addition there were several reports suggesting that the SpHb was significantly correlated with the laboratory Hb during surgical procedures with substantial blood loss [9,10] . The present study revealed that noninvasive SpHb measurement with pulse co-oximetry was significantly correlated with laboratory measurement of Hb.…”

Background: Total Hemoglobin(Hb) measurement is one of the most common and important parameter that is investigated in the laboratory. This non invasive method allows pain free continuous online patient monitoring with minimum risk of infection and facilitates real time data monitoring allowing immediate clinical reaction to the measured data. The objective of the study is to test the efficacy of pulse co-oximeter .Methods: Present study is a prospective comparative study. A total of 261 patients enrolled for the study after their consent. Non invasively measured SpHb values and invasively measured Hb values were then compared by using Bland Altman statistical analysis .Result: Pulse co-oximeter recorded/displayed SpHb in 90.8% patients and did not display SpHb in 9.2% of patients. Out of which 73-75% patients Hb showed variation of less than or equal to 2gms and 20-24% patients Hb showed variation of more than 2 gms. On Bland Altmann comparative analysis of SpHb and Hb revealed bias and limits of agreement was 0.2+3.3gm/d and 95% of the measurements fell within two standard deviation of the mean difference and P value < 0.001 represents good correlation between SpHb and Hb of Lab1 and Lab 2. Conclusion:Pulse co-oximeter can be used as a screening tool for Hb measurement . It determines Hb instantly and non invasively with 73-75% of the values show variation of less than or equal to 2gms. Further studies are needed to determine financial aspects and needs upgradation in terms of accuracy of the instrument.

“…The current investigation was integrated into a larger study pertaining to efficacy, safety, and pharmacodynamics of praziquantel in preschool-aged (2-5 years) and schoolaged (6)(7)(8)(9)(10)(11)(12)(13)(14)(15) The study staff was skilled at both Hb measuring systems. The same study staff used the Hb-measuring devices throughout the study.…”

“…Several devices are now commercially available and have been studied in a variety of settings with somewhat mixed results when compared with both invasive point-of-care devices and venous blood samples processed on a laboratory analyzer. [11][12][13][14][15] A recent meta-analysis identified 39 relevant studies and concluded that noninvasive Masimo Pronto-7 ® devices provide an unbiased, pooled estimate of laboratory Hb, yet have lower precision and wider 95% limits of agreement than invasive HemoCue devices. 16 Representative data on anemia are sparse in settings where anemia is most prevalent and particularly in settings without clinical facilities, where noninvasive methods are welcomed by both patients and medical personnel.…”

Abstract. Anemia remains a major public health issue in many African communities. We compared a novel, commercially available noninvasive hemoglobin (Hb)-measuring device to direct Hb measurements by finger-prick samples in a pediatric cohort in rural Côte d'Ivoire. Noninvasive Hb measurements were attempted in 191 children 2-15 years of age and obtained in 102 (53.5%) children. The median Hb for the 102 children was 12.0 g/dL (interquartile range [IQR] = 11.3-12.7 g/dL) for conventional absorptiometry and 13.3 g/dL (IQR = 12.1-14.2 g/dL) for noninvasive measurements. A Bland-Altman analysis demonstrated a median bias of +1
