Recently, the problem of hypoxia caused by jogging is attracting attention. To solve this problem, this paper proposed a new solution. This paper proved that as a vocalization method of reading aloud, it is possible to increase air intake and activate lung function to exchange more air and obtain more oxygen. Then, blood oxygen saturation was used as an evaluation index for the body's oxygen content level to prove its effectiveness. A photoelectric pulse oximeter developed on the basis of different light absorption principles in blood was used to test blood oxygen saturation. Experimental results show that a certain degree of hypoxia is induced when a lot of oxygen is required due to jogging. Therefore, it was proved that the new vocal breathing method by reading books can increase the blood oxygen saturation of the body and improve the hypoxia of the body. Reading vocal breathing is a simple and efficient oxygen saturation recovery breathing method.

Since the current tendencies show us the increasing number of cerebral palsy children and the standard longevity, we need to find out more research about the following various problems. Therefore I have tried to figure out the difference of oxygen saturation and heart rate between before ambulation and after. Objects chosen are 17 C.P children on the process of treatment those who were able to walk and 8 normal children in Ah-San hospital, Gang-Nung. They haven't had either any operation or suffered heart disease and I measured their oxygen saturation and heart rate by using pulse-oximeter and are analyzed by SPSS (10.07 version). Results are the followings; 1. There was no difference of oxygen saturation and heart rate between pre-ambulation and post-ambulation of normal and spastic hemiplegia children. 2. There showed the significant statistic difference of oxygen saturation, heart rate between pre-ambulates and post-ambulation of normal and spastic diplegia(p<.05). 3. There was no difference of oxygen saturation, heart rate in C.P between(p>.05), but shows the significant statistic difference in heart rate(p<.05). As I compared the oxygen saturation and heart rate of spastic and normal children on between pre-ambulation and post-ambulation, theres is significant statistic difference on both items (p<.05). However there was no difference of oxygen saturation among hemiplegia, normal and diplegia children while the pulse rate showed the significant difference(p<.05). According to this clinical research, CP children's oxygen saturation and heart rate had no change between pre and post compared to normal children. But there was difference in diplegia. This is why we need to invest time to study these kinds of research about various analysis and comparison of oxygen saturation and heart rate, and furthermore making use of pulse-oxymetry in physical therapy room for the children involved would be beneficial to calculate in accuracy without any discomfort for the patient as well.

Purpose: This study aimed to compare the oxygen saturation measured at fingertips with unpolished and self-artificial nails (sticker, tip) using a portable pulse oximeter. Methods: The sample comprised 27 women who had used nail care services. Using a pulse oximeter, oxygen saturation was measured at fingertips with unpolished nails in a stable state. Self-fabricated sticker and tip nails were attached to the right and left hands, respectively, using five nail colors (black, blue, green, purple, and brown). Oxygen saturation was measured at fingertips with self-fabricated nails first in the usual manner and then measured again by rotating the oximeter by 90°. Values of oxygen saturation were compared and analyzed using the Friedman test and Wilcoxon signed-rank test with Bonferroni correction using IBM SPSS 26.0. Results: Oxygen saturation values were significantly different among colors for both sticker nails (p=.036) and tip nails (p=.000), with black self-artificial nails tending to demonstrate lower oxygen saturation. Moreover, oxygen saturation values obtained by measuring the usual way on unpolished nails was significantly different than those obtained by rotating the oximeter by 90° on thumb with sticker (p=.001) and tip nails (p=.001). Conclusion: The findings of this study suggest that oxygen saturation should be measured on other fingers except for thumb instead of removing the self-artificial nails in emergency situations. For patients with black self-artificial nails, is the findings recommend measuring oxygen saturation at other body parts such as toes, earlobes, forehead, etc.

In this study, changes in verbal cognitive performance, blood oxygen saturation and heart rate due to 30％ concentration oxygen supply were observed. Five male (24.6±0.9) and five female (22.2±1.9) college students were asked to perform 28 verbal cognitive tasks of the same difficulty during two types of oxygen (concentration 21％, 30％) administration. The experimental sequence consisted of Rest1 (1 min.), Control (1 min.), Task (4 min.), and Rest2 (4 min.) and the physiological signals such as blood oxygen saturation and heart rate were measured throughout the stages. The experimental result showed that the performance increased significantly at 30％'s concentration of oxygen rather than 21％'s, which shows oxygen supply has positive influence on verbal cognitive performance. When 30％ concentration oxygen is supplied, the oxygen saturation in the blood significantly increased comparing to 21％. The heart rate showed no significant difference. Significant correlations were found between changes in oxygen saturation and cognitive performance. It is suggested that 30％ oxygen can stimulate brain activation by increasing actual blood oxygen concentration in the process of cognitive performance.

There is a delicate balance between too little and too much supplemental oxygen exposure in premature infants. Since underuse and overuse of supplemental oxygen can harm premature infants, oxygen saturation levels must be monitored and kept at less than 95% to prevent reactive oxygen species-related diseases, such as retinopathy of prematurity and bronchopulmonary dysplasia. At the same time, desaturation below 80 to 85% must be avoided to prevent adverse consequences, such as cerebral palsy. It is still unclear what range of oxygen saturation is appropriate for premature infants; however, until the results of further studies are available, a reasonable target for pulse oxygen saturation ($SpO_2$) is 90 to 93% with an intermittent review of the correlation between $SpO_2$ and the partial pressure of arterial oxygen tension ($PaO_2$). Because optimal oxygenation depends on individuals at the bedside making ongoing adjustments, each unit must define an optimal target range and set alarm limits according to their own equipment or conditions. All staff must be aware of these values and adjust the concentration of supplemental oxygen frequently.

The purpose of this study was to examine differences between male and female in blood oxygen saturation due to 93% oxygen administration of the three levels (1L/min, 3L/min, 5L/min). Ten healthy male ($25.0{\pm}1.8$ years) and ten female ($23.7{\pm}1.9$ years) college students were selected as the subjects for this study. The experiment consisted of three runs, i.e., the three levels of 93% oxygen administration, respectively. The each run consisted of three phases, i.e., Rest 1 (5 min), Hyperoxia (10 min), and Rest 2 (5 min). Blood oxygen saturation were measured throughout the three phases. By increasing the supply rate of highly concentrated oxygen, rising rate of blood oxygen saturation was increased. Blood oxygen saturation of female was higher than male regardless of supply rate of highly concentrated oxygen and phases.

Purpose: The purpose of this study was to examine the effects of the one-time aerobic exercise on pulmonary function, oxygen saturation, and smoking in male college students in their 20's. Methods: The experiment was performed on 11 healthy men who had no musculoskeletal or neurological diseases and who smoked. The subjects performed an aerobic exercise for 30 minutes, using a step box. Before and after the exercise, forced vital capacity (FVC), forced expiratory volume for one second (FEV1), and oxygen saturation were measured. Results: Between the two measurements, there were no significant differences in oxygen saturation (p>.05). However, the differences in FVC and FEV1 were statistically significant (p<.05). Conclusions: The results of this study demonstrate that a one-time aerobic exercise improves pulmonary function.

Purpose: To investigate the effect of nonnutritive sucking(NNS) on the heart rate, oxygen saturation, and behavioral state of premature infants. Method: From December 15, 2004 to February 15, 2005, 20 premature infants hospitalized in the neonatal intensive care units were assigned to an experimental group (10), or a control group (10). Circular pacifiers for premature infants (Johnson, U.S.A.), which had been packed with $2{\times}2$ gauzes to create a vacuum, were used for 5 minutes, one hour after feeding for 5 days. Heart rates and oxygen saturation were checked every minute for 10 minutes once a day and behavioral states were monitored through video recording at the same time. Results: Changes in heart rate, oxygen saturation and behavioral state were found to show significant differences between the experimental group and the control group according to the point in time, and interactions were found between the group and the point of time. However, for behavioral state, no significant difference was found between the experimental group and the control group after the NNS was removed. Conclusion: From the results of this study it is possible to conclude that NNS is a positive intervention to bring about increased oxygen saturation and soothed behavioral state for premature infants.

Purpose: The purpose of this study was to compare the difference of change in oxygen saturation, vital signs and suction time taken for the suctioning during endotracheal suctioning performed with closed suction system and with opened suction system. Methods: Data were collected from 31 adult patients with ventilator treatment who were admitted to a university hospital in Seoul and the collection period was from July 1 to November 15, 2005. Oxygen saturation, heart rate, respiration rate and mean arterial pressure were collected immediately prior to the suctioning intervention, during and 1 and 5 minutes after the suctioning from opened suction system and closed suction system. Results: 1) The difference in oxygen saturation was statistically significant in recovery time for oxygen saturation to return to baseline values after suctioning was significantly rapid on closed suction system (p<.05). 2) The difference in heart rate, respiration rate and mean arterial pressure was statistically insignificant 3) The suction time was shorter in closed suction system. Conclusion: Closed suction system is more efficient, as compared with the open suction system in the ventilator treatment.

Blood oxygen saturation ($SpO_2$) is so important to be called bio-signal of the fifth. The measurement of blood oxygen saturation based on broad-ban light source has advantages of simple testing facility and easy understanding. This paper proposes a LabVIEW program which measures blood oxygen saturation based on broad-band light source. It combines LabVIEW and MATLAB, utilizing different light absorptions of oxyhemoglobin and deoxyhemoglobin in the visual wavelength range of 450nm-750nm to determine blood oxygen saturation. In order to improve accuracy through reducing the impact of hand shaking, the probe is fixed to the motor stage and then move a constant distance between the probe and the sample to be measured. Experimental results show that the proposed method noticeably increases the accuracy and saves time compared with the conventional methods.
