“…The resolution is even 35 times better than achieved by Macknet et al . 27 In addition, as discussed in earlier Sec. III D, since SNR of above methods requires a very fine tuning of wavelength combination, therefore, operating at a single wavelength with the proposed SPR-based scheme is another huge advantage in terms of ease of hemoglobin determination.…”

Surface plasmon resonance (SPR) sensor for the detection of hemoglobin concentration in human blood is proposed. Previous experimental results describing variation of refractive index of human blood with hemoglobin concentration at different wavelengths are considered for theoretical calculations. The angular interrogation method along with silica substrate and gold layer is considered. The sensor's performance is closely analyzed in terms of well-defined performance parameters: sensitivity, accuracy, resolution, and signal-to-noise ratio, in order to achieve reliable and accurate hemoglobin detection. The influence of operating wavelength on the performance of sensor scheme is critically investigated. Performance comparison for two different substrates is carried out. The results are explained in terms of light coupling and plasmon resonance condition. The proposed biosensor has the potential to provide high sensitivity, accuracy, and large operating range of hemoglobin detection, along with much higher resolution compared with existing methods, thereby opening an easy and reliable window for biomedical applications.

“…Moreover, by assessing the Rad7 in cardiac surgery patients, our results are more relevant to clinical practice than results from healthy volunteers. In another abstract, Lamhaut et al 21 reported a good correlation between the Masimo reading and the laboratory result in patients undergoing a urologic surgical procedure with risk of hemorrhage. However, the standard deviation was 1.11 g/dL so that the Hb bias in 95% of patients ranged between Ϯ2 g/dL, which is quite high.…”

Our study demonstrates poor correlation between hemoglobin measured noninvasively by multiwavelength pulse oximetry and a laboratory hematology analyzer. The difference was greater when the pulse oximetry perfusion index was low, as may occur in shock, hypothermia, or vasoconstriction patients. The multiwavelength pulse oximetry is not sufficiently accurate for clinical use in a cardiovascular intensive care unit.

“…For instance, multi-wavelength pulse oximetry method [19][20][21], spectrophotometry, and RBC count method [22] are a few examples. Different methods have their different performance parameters depending on the methodology.…”

Phase interrogation based surface plasmon resonance (SPR) biosensor is proposed for the determination of Hb concentration. Previous experimental results describing variation of refractive index of human blood with Hb concentration at different wavelengths are considered for design simulations. The biosensor design with silica substrate and gold layer is considered. The sensor's performance is closely analyzed in terms of phase sensitivity and resolution. The influence of operating wavelength on biosensor's performance for Hb measurement is critically investigated, which points to carry out the Hb measurement at a shorter wavelength as phase sensitivity and resolution increase significantly with decrease in wavelength. The results are explained in terms of suitable physical concepts such as radiation damping. Use of contamination-preventing biochemical layer ascertains the stability of measurement with the intended SPR biosensor probe. The simulation results also highlight that the resolution of Hb measurement achievable with the proposed biosensor is much higher compared with several existing methods.
