The aim of this study was to investigate the effect of acute aerobic exercise on arterial blood hemoglobin oxygen saturation in athletes.36 healthy male athletes participated voluntarily with the age (20.9 ± 1.6 yrs), weight (69.8 ± 5.5 kg) and height (169.6 ± 3.7 cm), who studied at school of physical education and practiced 90 minutes of exercise 6 days a week,. This study was conducted with the approval of Ethics Committee of Health Sciences Institute with session date specified in article of Ethics Committee, dated in 13.09.2017.The heights, body weights and VO2 max values of participants were determined by VO2 max shuttle run test once, pre- and post-shuttle run heart rates and oxygen saturations were determined by pulse oximetry. The statistical analysis of data was made in SPSS 21.0 for windows package program. The normality test of data was done by Kolmogorov-Smirnov test, and it was found that data was not normally distributed. The Wilcoxon test, a nonparametric test, was used to determine for difference between pre-test and post-test. The significance value was taken at level 0.01.As a result of statistical analyses, it was determined that there was a statistically significant difference between oxygen saturations and heart rates of participants before and after exercise. In conclusion, it can be said that acute aerobic exercise can reduce oxygen saturation.

In anaesthetic practice the risk of hypoxia and arterial blood gas disturbances is evident, as most anaesthetic regimens depress the respiratory function. Hypoxia may be extended during recovery, and for this reason we wished to investigate if oxygen supply during a one hour post-operative period reduced the development of hypoxia and respiratory acidosis in rats anaesthetized with fentanyl/fluanisone and midazolam. Twelve Sprague Dawley rats underwent surgery and were divided in two groups, breathing either 100% oxygen or atmospheric air during a post-operative period. The peripheral blood oxygen saturation and arterial acid-base status were analyzed for differences between the two groups. We found that oxygen supply after surgery prevented hypoxia but did not result in a significant difference in the blood acid-base status. All rats developed respiratory acidosis, which could not be reversed by supplemental oxygen supply. We concluded that oxygen supply improved oxygen saturation and avoided hypoxia but did not have an influence on the acid-base status.

Abstract: During physical activity, blood flow and oxygen usage will increase in order to transport oxygen which is required by muscles during exercise. One of the parameters to check the amount of oxygen that is bound to hemoglobin is oxygen saturation. This study aimed to determine the level of blood oxygen saturation of those who consumed mineral water and high oxygenated water during zumba gymnastics. This was an analytical experiments method with pre and post test approach. Total samples were 31 people who met the criteria and were willing to become the respondents. Data were analyzed using Wilcoxon Test. The results showed that the oxygen saturation before and after consuming mineral water (97.5±0.9) and (97.7±1.03) meanwhile before and after consuming high oxygenated water (97.6±0.75) and (98.7±0.44). The Wilcoxon test showed that there was a significant difference of blood oxygen saturation between before and after consuming high-oxygenated water (p=0.000) whereas for other respondents who consumed mineral water, there was no significant difference in their condition before and after consuming mineral water (p=0.198). Conclusion: There was a higher increase in blood oxygen saturation value before and after consuming oxygenated water compared to before and after consuming mineral water.Keywords: oxygen saturation, mineral water, and oxygenated water.Abstrak: Ketika beraktivitas fisik, aliran darah dan penggunaan oksigen akan meningkat untuk mengangkut oksigen yang diperlukan pada otot selama latihan.

Abstract One hundred and twenty-six yearling angus steers (initial body weight 445.87 ± 7.13 kg) were utilized in a 2 x 2 factorial design to evaluate the impacts of bunk management and modified distillers grains plus solubles (mDGS) inclusion on feedlot performance, hydrogen sulfide concentrations and blood oxygen saturation. Treatments included bunk management strategy either control bunk management (CON; clean bunks at the time of next day’s feeding) or long bunk management (LONG; feed remaining at time of next day’s feeding), and two inclusion rates of mDGS either 25% or 50% (DM Basis). On d 0, 7, 14, 21, 28 and 35 rumen gas samples were collected via rumenocentesis, and arterial blood samples were collected on two steers from each pen. No differences (P ≥ 0.09) were observed for dry matter intake, average daily gain and gain-to-feed ratio for bunk management or mDGS inclusion. Hot carcass weight, ribeye area, marbling score and quality grade were not affected (P ≥ 0.48) by either bunk management or mDGS inclusion. Back fat was greater (P = 0.04) for CON steers compared to LONG (1.30 vs 1.12 ± 0.05cm, respectively), but was not affected (P = 0.59) by mDGS inclusion. Steers on CON had greater (P = 0.03) yield grades compared to LONG (3.21 vs 2.96 ± 0.11, respectively). Bunk management strategy did not impact hydrogen sulfide concentrations or blood oxygen saturation (P = 0.82). Hydrogen sulfide concentrations increased (P < 0.001) with increasing mDGS inclusion. Blood oxygen saturation was influenced by day of sampling (P = 0.01). Blood oxygen saturation was not affected (P = 0.07) by mDGS inclusion. The fact that ruminal hydrogen sulfide concentrations increased while blood oxygen saturation remained similar raises questions about the quantity of hydrogen sulfide and metabolic fate of excess hydrogen sulfide in the blood of ruminant animals.

We present the use of Extended Modified Lambert–Beer model for optical monitoring of mean blood oxygen saturation ( S m O 2) via a fitting procedure. This work focuses on the absorption characteristics of hemoglobin derivatives in the wavelength range of 520–600 nm to give the best estimates of S m O 2. The study of the feasibility of applying this analytic method to skin oximetry is via spectroscopy data collected from fingertips of four healthy volunteers both at rest and during arterial blood occlusion condition. The results revealed a decrease in the mean of mean and standard deviation of S m O 2 value of fingertips from 94.5 ± 2.19% when volunteers were at rest to 56.76 ± 5.8% during the arterial blood occlusion measurement. The larger variation in the value estimated for blood occlusion condition could be a result of differences in volunteers' physical fitness and hypertension status. These estimated S m O 2 values agreed reasonably well with the value reported in most of the previous studies. This work concluded that the proposed technique can potentially be used as a complementary technique to clinical assessment of skin grafts and burnt skin.

This paper presents the use of a handheld technology for noninvasive prediction of one’s transcutaneous blood oxygen saturation, StO2, via an in-house developed skin oxygenation system. The quantification strategy involved the use of wavelength dependent Modified Lambert Beer law and is based on light signals of wavelengths 532 nm, 560 nm and 650 nm reflected from the selected skin site. This study performed at rest and arterial blood occlusion experiment on left palm of the hand of five healthy Asian volunteers to evaluate the performance of the system and to verify the validity of the predicted results. The preliminary results revealed a considerable decrease in the predicted mean percent StO2 value from 63.7 ± 13.2 % for at rest condition to 52.2 ± 11.4 % after a pressure of 140 mmHg was applied on upper left arm of these recruits for 120 seconds. This work concluded that the developed optical system is able to provide comprehensive information on spatially dependent StO2 and it has unlimited skin access, hence may be potentially used in field applications to assess the skin oxygen level of those in workforce whose job is at risk of exposure to poisonous gases.

Snoring gets no respect.  It also gets little to no medical therapy.  Why is this?  How can something that is clearly pathological based on epidemiologic research not be diagnosed and treated with effective therapy?  The problem is the lack of a credible, objective index of pathology during snoring.  Pulse oximetry detects drops in arterial blood oxygen saturation (SpO2) associated with obstructive sleep apnea and hypopnea events in polysomnographic (PSG) testing.  When no desaturation is present, evidence of sleep disturbance is required to indicate the presence of pathology.  However, obstruction at the mild end of the continuum of sleep disordered breathing (SDB) can occur without producing a drop in SpO2 or sleep disturbance; in which case it is referred to as ‘primary snoring.’ Although statistically associated with co-morbidities of SDB, without there being a drop in SpO2 or sleep disturbance, primary snoring is not thought to be pathologic enough to warrant diagnosis or treatment.  One promising means of detecting the pathological processes associated with primary snoring is molecular tissue oximetry, which detects skin tissue oxygen need, vs. oxygen supply.   In cases of hypoxic challenge, regulatory mechanisms restrict blood flow to the skin to preferentially maintain blood oxygen supply to more vital organs.  As a result, molecular tissue oximetry of the skin is a more sensitive measure of inadequate breathing than pulse oximetry measuring blood oxygen saturation.  In this article we review molecular tissue oximetry technology and methodology and make the case that it is a promising tool for identifying pathology occurring in association with primary snoring.

Introduction: The aim of this study was to compare ionized calcium (iCa) concentrations in arterial heparinized blood and venous serum and to investigate time-dependent variation of iCa in serum samples centrifuged and analysed at different times. Materials and methods: Ionized calcium was measured (N = 25) in arterial blood within 20 min after puncture, and in serum within 10 min after centrifugation conducted 30 min after sampling. Effect of time between sampling and centrifugation was examined in three tubes (N = 30) centrifuged 15, 30 and 60 min after sampling, and analysed within 10 min. Effect of time between centrifugation and analysis was investigated in three tubes (N = 31) centrifuged 30 min after sampling and analysed: 0-10, 30-40 and 90-100 min after centrifugation. Ionized calcium was measured on the Siemens RapidLab 348EX analysers. Statistical significance was tested using Wilcoxon test and ANOVA analysis. Clinical significance was judged against reference change values (RCV). Results: No statistically significant difference was found between iCa in arterial blood and serum (P = 0.274). A statistically significant decrease was found: in tubes centrifuged 60 and 15 min after sampling versus 30 min (P = 0.005, P = 0.003); and in tubes analysed 30-40 and 90-100 min after centrifugation versus 0-10 min (P = 0.021, P = 0.027). Clinically significant changes were observed: 60 versus 30 min (centrifugation) and 90-100 versus 0-10 and 30-40 min (analysis). Conclusions: Timely analysed arterial blood and serum samples can be used interchangeably. To avoid clinically significant variations, serum tubes should be centrifuged within 30 min after sampling, and analysis should be performed within 30 min after centrifugation.

Abstract Objectives. Although multiple mechanisms, including autonomic dysfunction, seem to link sleep-disordered breathing (SDB) with dyslipidemia in animal studies, the data in clinical studies are limited. The aim of this study was to explore the association of lipoprotein levels with SDB measures in healthy habitual snorers. We supposed that autonomic dysfunction is the linking mechanism. Methods. We enrolled 110 previously healthy subjects with complaints of habitual snoring. To assess SDB, polysomnography was performed. Blood samples for the analysis of total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein cholesterol (LDL), and triglycerides (TG) were obtained in a fasting condition after the polysomnography. Baroreflex sensitivity (BRS) was used to assess the autonomic dysfunction. Results. In stepwise multiple linear regression analysis, minimal nocturnal blood oxygen saturation (beta=–0.240, p=0.020) and neck circumference (beta=0.224, p=0.03) were the only significant contributors in model predicting TG. SDB measures were not identified as significant contributors in models predicting TC, LDL, and HDL. We failed to find any significant difference in BRS in SDB subjects when compared according to the presence or absence of hypercholesterolemia/ hypertriglyceridemia. In SDB subjects, the area under the curve in a receiver operating curve to predict hypercholesterolemia and hypertriglyceridemia by BRS was 0.468 (95% CI: 0.328–0.608) and 0.425 (95% CI: 0.304–0.546), respectively. Conclusions. Our results suggest that minimal nocturnal blood oxygen saturation is significant contributor in model predicting TG. No significant decrease in BRS was found in SDB subjects with hypercholesterolemia and hypertriglyceridemia. In SDB subjects, the role of autonomic dys-function in the development of dyslipidemia remains controversial.
