Journal of Clinical Nursing Apr 2016The research was conducted to evaluate oxygen saturation values measured in healthy individuals in different body positions.
AIMS AND OBJECTIVES
The research was conducted to evaluate oxygen saturation values measured in healthy individuals in different body positions.
BACKGROUND
Changes in position affect ventilation-perfusion rates, oxygen transport and lung volume in normal lungs. There have been few studies and not enough information about which positioning of a healthy individual can increase oxygenation.
DESIGN
A descriptive study.
METHODS
A sample of 103 healthy individuals with no chronic disease, anaemia or pain was included in the research. Individuals were positioned in five different positions: sitting upright, supine position, prone position, lying on the left side and lying on the right side. Oxygen saturation and pulse rates were then measured and recorded after the individuals held each position for ten minutes.
RESULTS
It was found that the average oxygen saturation value when measured while sitting in an upright position in a chair was significantly higher than that measured when the individual was lying on the right or left side of the body. Oxygen saturation values measured in the five different body positions were significantly higher in women, in individuals below the age of 35, in those with Body Mass Indexes of below 25 kg/m(2), and in nonsmokers.
CONCLUSION
All of the oxygen saturation values measured in the five different body positions were in the normal range. Although oxygen saturation values were within the normal range in the five different body positions, post hoc analysis showed that the best oxygenation was in the 'sitting upright' position while the lowest oxygenation was in the supine position.
RELEVANCE TO CLINICAL PRACTICE
Based on the results of this research, it can be concluded that the differences among oxygen saturation values according to the different body positions were statistically significant.

Review
PURPOSE OF REVIEW
Why is pulse oximetry a standard monitor, whereas tissue oximeter is not? Is this a double-standard treatment?
RECENT FINDINGS
There appears to be a lack of enthusiasm for a continual investigation into whether the use of pulse oximetry leads to reduced morbidity and mortality in acute care although there is no robust evidence attesting to its outcome benefits. In contrast, research investigating the outcome effectiveness of tissue oximetry-guided care is consistently ongoing. A recent randomized controlled trial involving 800 patients who underwent laparoscopic hysterectomy found that, although muscular tissue oxygen saturation-guided care did not reduce the overall occurrence of postoperative nausea and vomiting for all patients, it did reduce the occurrence of these symptoms in patients who had a body mass index ≥25. It was also observed that muscular tissue oxygen saturation increases when blood pressure falls following the administration of nicardipine. These studies highlight the persistence of interest in understanding the value of tissue oximetry in patient care.
SUMMARY
Pulse oximetry and tissue oximetry are treated differently although neither monitor has robust evidence attesting to its outcome benefits. This difference may root in the difference in the physiology they monitor, the cost, the ease of use/interpretation/intervention and the relevance to patient safety and care quality. Pulse oxygen saturation represents a vital sign, whereas tissue oxygen saturation is likely a quality sign; however, further research endeavors are required to fully understand how to best use tissue oximetry.

Comparative Study
We studied 54 neonates with acute cardiorespiratory illness and 21 infants with bronchopulmonary dysplasia, to evaluate the accuracy of a nonheated pulse oximeter in predicting arterial oxygen saturation (SaO2). We also studied the accuracy of transcutaneous oxygen tension (tcPO2) in estimating arterial oxygen tension (PaO2) in infants with bronchopulmonary dysplasia. We compared pulse oximeter SaO2 with simultaneously measured SaO2 (range 78% to 100%) using a co-oximeter. Over a wide range of values for heart rate, blood pressure, hematocrit, PO2, PCO2, and pH, linear regression analysis revealed a close correlation between in vivo pulse oximeter readings and in vitro SaO2 measurements in patients with acute (r = 0.86, Y = 29.64 + 0.68X) and chronic (r = 0.91, Y = 6.29 + 0.96X) disease. Regression analysis of tcPO2 versus PaO2 showed an r value of 0.76 in infants with bronchopulmonary dysplasia. In these patients the mean difference between pulse oximeter SaO2 and in vitro SaO2 was 2.9% +/- 1.8% (SD), whereas the mean difference between tcPO2 and PaO2 was -14.5 +/- 11.1 mm Hg. Fetal hemoglobin ranged from 4.3% to 95%. We conclude that pulse oximetry is an appropriate alternative to tcPO2 for continuous oxygen monitoring in newborn infants with acute cardiorespiratory illnesses and chronic lung disease.

OBJECTIVE
The World Health Organization and Centers for Disease Control and Prevention recommend the use of face masks in public. This study aimed to evaluate the effects of face masks on pulse rate and partial blood oxygen saturation in patients without cardiorespiratory disorders.
METHODS
A total of 150 volunteers of both sexes were divided into three groups (n=50) according to age (children, young adults, and older adults). The partial blood oxygen saturation and pulse rate were measured for each volunteer using a digital oximeter while wearing a facial mask and remaining at rest. The masks were removed for two minutes, and partial blood oxygen saturation and pulse rate were remeasured. The materials and types of masks used were recorded. The t -test for paired samples was used to compare the mean values obtained before and after removing the masks.
RESULTS
The most frequently used mask was a two-layered cloth (64.7%). A decrease in pulse rate was observed after removing the face mask in males, particularly in children (p=0.006) and young adults (p=0.034). Partial blood oxygen saturation levels increased in young adult males after mask removal (p=0.01).
CONCLUSION
The two-layer cotton tissue face masks are associated with a higher pulse rate and reduced arterial blood oxygen saturation without associated clinical disorders, mainly in adult men with a lower tolerance to breathing and ear discomfort.

Randomized Controlled Trial
OBJECTIVE
To evaluate cardiorespiratory alterations due to a single session of hyperbaric oxygen therapy.
METHOD
Randomized study with patients: a control group and hyperbaric oxygen therapy. Evaluations occurred in the beginning, during, and after exposure to pure oxygen above atmosphere for 2 hours. Systemic blood pressure, peripheral oxygen saturation, pulse rate, lung volume and lung capacity, and maximal inspiratory and expiratory pressures were evaluated. Peripheral oxygen saturation, pulse rate, and systemic blood pressure were evaluated during the pressurizing in the first hour. Data were evaluated by means of ANOVA, Mann-Whitney, and independent t-test (p<0.05).
RESULTS
A total of 14 adult patients were evaluated. In the group under therapy (seven subjects), aged: 49.57±14.59 years, there was a decrease in the pulse rate of 16 beats per minute after 35 minutes of therapy (intragroup analysis), and the peripheral oxygen saturation was higher within the same period compared to the control group.
CONCLUSION
The hyperbaric oxygen therapy promotes cardiorespiratory alterations with the increase of the peripheral oxygen saturation and decrease of the pulse rate, without altering blood pressure levels and the strength, volumes, and respiratory capacities.

OBJECTIVE
Using fetal pulse oximetry, we sought to quantify the impact of maternal oxygen administration in the management of nonreassuring fetal heart rate patterns.
STUDY DESIGN
In fetuses with specified abnormal nonreassuring fetal heart rate patterns, oxygen was administered to the mother, and fetal oxygenation was monitored with fetal pulse oximetry. After the fetal oxygen saturation on room air was recorded as a baseline, oxygen was administered to the mother for 30 minutes at 40% fraction of inspired oxygen and then 30 minutes at 100% of inspired oxygen. The average fetal oxygen saturation during the last 15 minutes of each period was calculated. Paired Student t test was used for comparison to baseline values.
RESULTS
Compared with baseline values, a significant increase in fetal oxygen saturation was identified in women who received oxygen at 40% fraction of inspired oxygen (mean increase, 4.9%; P = .001) and at 100% of inspired oxygen (mean increase, 6.5%; P = .003).
CONCLUSION
The administration of supplemental oxygen to laboring patients with nonreassuring fetal heart rate patterns increases fetal oxygen saturation substantially and significantly. Fetuses with the lowest initial oxygen saturations appear to increase the most.

Review
Pulse oximetry is commonly used to assist clinicians in assessment and management of newly born infants in the delivery room (DR). In many DRs, pulse oximetry is now the standard of care for managing high risk infants, enabling immediate and dynamic assessment of oxygenation and heart rate. However, there is little evidence that using pulse oximetry in the DR improves short and long term outcomes. We review the current literature on using pulse oximetry to measure oxygen saturation and heart rate and how to apply current evidence to management in the DR.

The purpose of the investigation was to determine the relative oxygen consumption (VO2), heart rate and oxygen pulse associated with the constituent elements of an exercise-to-music class. Six women exercise-to-music leaders with a mean(s.d.) age, weight and height of 33.2(5.2) years, 51.0(2.8) kg and 157.9(5.6) cm respectively, completed five distinct exercise-to-music movement elements. The movement elements were of a locomoter (circuit, jump and low impact) and callisthenic (prone and side/supine) nature. The movement elements were distinguishable from one another in terms of their movement patterns, posture and tempo. Relative VO2 values were greatest for the circuit element (40.6 ml kg-1 min-1) and least for the side/supine element (20.0 ml kg-1 min-1). The differences in VO2 between the locomotrr and callisthenic elements were significant (circuit approximately jump approximately low impact > prone approximately side/supine). However, effect size data suggested that the differences between the low impact and jump elements and the prone and side/supine elements were of practical significance (circuit approximately jump > low impact > prone > side/supine). With a single exception similar parametric statistics and effect size trends were identified for absolute heart rate. Specifically, the heart rate associated with the low impact element was not significantly greater than the prone element. The oxygen pulse associated with the locomotor elements was significantly greater than the callisthenic elements (circuit approximately jump approximately low impact > prone > side/supine). This suggested that heart rate may be an inappropriate index for making comparisons between exercise-to-music elements. Reasons for differences in oxygen uptake values between movement elements are discussed.
