“…In commercial pulse oximeters, which are the standard way for measuring oxygen saturation, the accuracy is 2-4% for saturation levels of 70-100%. Below these saturation levels the accuracy is decreased [8,9]. Although the accuracy level achieved in these experiments is slightly higher, it is not dependent on the material ratio and therefore encouraging.…”

This study's objective is to validate a method for the measurement of two compound phantoms as a proof of concept for oxygen saturation level measurement via a thermal imaging bundle. The method consists of a thermal imaging system and an algorithm which estimates the compound concentration according to temperature rise. A temperature rise is obtained by illuminating the tissue with a laser with different wavelengths in the NIR range and measured using a thermal camera. A coherent thermal imaging bundle was used for image transmittance for minimal invasive transendoscopic use. The algorithm's estimation ability was evaluated using agar phantoms of varying Methylene Blue and ICG ratios as well as blood samples The Methylene Blue ratio in each phantom was estimated and the calculated average RMS of the error was 9.38%, a satisfying value for this stage, verifying the algorithm's and bundle's suitability for the use in a minimal invasive system.

Objective Determine whether the SpO2/FiO2 ratio correlates with the PaO2/FiO2 ratio in burned children with smoke inhalation injury (SII), with the goal of understanding if the SpO2/FiO2 ratio can serve as a surrogate for the PaO2/FiO2 ratio for the diagnosis of acute respiratory distress syndrome (ARDS). Design Retrospective chart review. Setting Shriners Hospitals for Children - Galveston. Patients All burned children with SII who were admitted from 1996 to 2014 and had simultaneously obtained SpO2, FiO2, and PaO2 measurements. Interventions None. Measurements and Main Results Two hundred seventy-three patients (63% male, 8 ± 5 years, 53 ± 24% total body surface area burns) were analyzed. SpO2/FiO2 ratios were divided into 4 subgroups based on SpO2 values (≤ 100%, ≤ 98%, ≤ 95%, ≤ 92%). Significance was accepted at r2 > 0.81. The r2 (number of matches) was 0.66 (23,072) for ≤ 100%, 0.87 (18,932) for ≤ 98%, 0.89 (7,056) for ≤ 95%, and 0.93 (4,229) for ≤ 92%. In the subgroup of patients who developed ARDS, r2 was 0.65 (8,357) for ≤ 100%, 0.89 (7,578) for ≤ 98%, 0.89 (4,115) for ≤ 95%, and 0.91 (2,288) ≤ 92%. Conclusions PaO2/FiO2 and SpO2/FiO2 strongly correlate in burned children with SII, with a SpO2 of <92% providing the strongest correlation. Thus, SpO2/FiO2 ratio may be able to serve as surrogate for PaO2/FiO2, especially when titrating FiO2 to achieve a SpO2 of 90–95% (i.e., in the ARDS range).

“…Conventional pulse oximeters employ transmission sensors with light emitters and detectors located on opposite sides of the tissue bed, and suitable for measurements from fingertips, toes or earlobes [37,38]. Pulse oximeter probes using reflectance sensors (with emitter and detector placed adjacently) have also become available, which can obtain measurements from the forehead [39].…”

“…The oximetry readings can be affected by the presence of dyshemoglobins (carboxyhemoglobin and methemoglobin), intravenous dyes, low perfusion states, skin pigmentation, anemia, use of nail polish, motion artifacts as well as poor operator knowledge [38].…”

The worldwide number of smokers exceeds one billion, and about 6 million people die per year, due to tobacco use. Smoking and its hazards exert a heavy toll on healthcare expenditure as well, in countries around the world. Patients with a history of smoking have a greater risk for pulmonary complications following surgical procedures.The Conventional technology relies on the use of arterial blood gas (ABG) analysis for monitoring gas saturation parameters in the blood but is invasive, expensive and cumbersome. Pulse CO-oximetry is a widely employed, operator-friendly, non-invasive monitoring method that yields comparable results to laboratory CO-oximetry and facilitates multi-parametric monitoring of the patients. It can accurately measure arterial oxygen saturation levels in heavy smokers who might have higher levels of circulating carboxyhemoglobin.The technology is cost-effective, can facilitate early detection of post-operative pulmonary complications and has the potential to reduce healthcare costs and improve clinical outcomes.Though clinical trials are yet to show benefit in patient monitoring from this technology, it is assumed to hold considerable promise in patients with risk factors for surgical complications.
