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.

Changes in visuospatial cognitive performance, blood oxygen saturation and heart rate due to the highly concentrated oxygen administration were observed in this study. Six male ($25.8 \pm$1.0) and six female (($23.8 \pm$ 1.9) adults were asked to perform 20 visuospatial tasks with the same level of difficulties by supplying two different oxygen levels (21%, 30%). Experiment consisted of Rest1 (1 min.), Control (1 min.), Task (4 min.), and Rest2 (4 min.) and physiological signals such as blood oxygen saturation and heart rate were measured through each stage. The result showed the accuracy of task performance increased significantly at 30% oxygen concentration compared with 21%, which means oxygen supply has positive effects on visuospatial cognitive performance. When 30% oxygen was supplied, blood oxygen saturation during control and task phases was increased and heart rate was decreased compared with 21%. It means that 30% oxygen can stimulate brain activities by directly increasing the actual level of blood oxygen concentration during cognitive performance, and enough oxygen supply during cognitive performance make heart rate decrease.

Purpose: This study aimed to confirm the effect of routine suctioning at a nursery for healthy newborns who have undergone immediate oronasopharyngeal bulb suctioning after birth in a delivery room through the observation of their oxygen saturation level, heart rate, respiration rate, the vomiting sign, and the number of instances of vomiting. Methods: Data were collected for 62 days from March 15 to May 15, 2009 at the nursery of a hospital located in Seoul. One hundred forty newborns were assigned to one of three groups: a no suction group, an oropharyngeal suction group, or a orogastric suction group. Collected data were analyzed with the SPSS WIN 15.0 program using ANOVA, cross tabulations and an independent 2-sample t-test. Results: Routine suctioning to healthy newborns resulted in decreasing oxygen saturation levels and increasing the heart and respiration rate regardless of the kind of suctioning. Stabilization of the oxygen saturation level and vital signs was also observed without suctioning. Conclusion: To prevent healthy newborns from the side effect of suctioning, selective suctioning is recommended.

Purpose: Packing the nose is a common procedure after the closed reduction of a nasal bone fracture to prevent postoperative complications, such as bleeding and adhesion formation as well as to stabilize the framework of the nasal bone. On the other hand, it is difficult for a patient to endure nasal packing because of breathing difficulties, headaches, chest discomfort, insomnia, general weakness and hypoxia. This study examined the availability of a bronchodilator to improve the decreased oxygen saturation and postoperative symptoms on nasal packing. Methods: From February, 2010 to July, 2010, a prospective randomized comparison of the incidence of a range of postoperative signs and symptoms was conducted on 60 patients, who did (n=30) and did not (n=30) undergo bronchodilator infusion (aminophylline 250 mg/10 mL + normal saline 100 mL IV qd) following nasal packing. The postoperative symptoms and oxygen saturation in the two groups were compared. Results: Patients who had infused the bronchodilator showed improved oxygen saturation. Nevertheless, there were no significant differences in the postoperative uncomfortable symptoms (dyspnea, headache, chest discomfort, insomnia, general weakness) between the two groups. Conclusion: A bronchodilator after nasal packing improves oxygen saturation by dilating the airway tract but it cannot reduce the uncomfortable symptoms caused by nasal obstruction. Overall, the bronchodilator is a useful medication for improving the level of oxygen saturation.

Pulse oximeter to monitor oxygen saturation during pediatric dental sedations enables early detection of hypoxemia. The purpose of this study was to monitor the hemoglobin oxygen saturation level and pulse rate of nonmedicated pediatric patients during routine restorative procedures to study the effect of procedure and treated jaw. We obtained data from 53 children treated at the Department of Pediatric Dentistry, Chonbuk national university hospital. Pulse rate and oxygen saturation were measured and recorded using pulse oximetry at each step of treatment. The results are as follows: 1. In non-anesthesia group, steep increase of pulse rate was observed during rubber dam application in the maxilla and during cavity preparation in the mandible. 2. In anesthesia group, pulse rate started to decrease after the rubber dam application in the maxilla, while its decrease observed since cavity preparation step in the mandible. 3. In non-anesthesia group, oxygen saturation level was relatively constant during all steps in the maxilla, but in mandible, it was higher during operation compared to its pre and post operation baseline. 4. In anesthesia group, oxygen saturation level was observed at 99% level through all steps in both jaw groups, and there was no statistical significance between the maxilla and the mandible groups(p>0.05). The purpose of this study was to evaluate the effect of routine dental treatment on the pulse rate and oxygen saturation level in nonmedicated pediatric patients during routine restorative procedures in the maxilla and mandible.

The simple imcroprocessor device was provided for the control of dissolved oxygen(DO) level. The DO analog signal output from fementer was used as a measurement variable and the agitation speed of fermenter was used as a manipulatio variable. Agitation speed was manipulated to maintain DO level above 10% of saturation condition during cell growth period with microprocessor. Since the experimental resultsshowed that the DO level was maintained above 10% and agitation speed was inverse proportional to DO level ithis simple control device can be used for the DO control of fermenter.

Methemoglobinemia is a blood disorder in which an abnormal amount of methemoglobin is produced, and prilocaine is one of the drugs that can cause this disorder. The maximum recommended dose of prilocaine is 8 mg/kg. We report a case of methemoglobinemia caused by the administration of 4.2 mg/kg of prilocaine without other methemoglobinemia-inducing drugs during general anesthesia. A 17-year-old girl with hyperthyroidism and anemia was scheduled to undergo maxillary sinus floor elevation and tooth extraction. The patient's peripheral oxygen saturation (SpO₂) decreased from 100% at arrival to 95% after receiving prilocaine with felypressin following induction of general anesthesia. However, the fraction of inspired oxygen was 0.6. Blood gas analysis showed that the methemoglobin level was 3.8% (normal level, 1%-2%), fractional oxygen saturation was 93.9%, partial pressure of oxygen was 327 mmHg, and arterial oxygen saturation was 97.6%. After administration of 1 mg/kg of methylene blue, her SpO₂ improved gradually to 99%, and the methemoglobin value decreased to 1.2%. When using prilocaine as a local anesthetic, it is important to be aware that methemoglobinemia may occur even at doses much lower than the maximum recommended dose.

Purpose: This study was conducted to examine the effects of Pericardium Kimek (K9) and Nei-Guan (P6) acupressure on relief of the anxiety, nausea, retching and physiologic changes (oxygen saturation, blood pressure, heart rate, temperature and respiration) in the patients undergoing unsedated esophagogastroduodenoscopy. Methods: A quasi-experimental research design was used. The participants were assigned into the listed three groups, i.e., the control group, the first experimental group (E1: K9 acupressure group) and the second experimental group (E2: P6 acupressure group). A total of 60 participants were included for analysis. Results: The severity of nausea (F=3.503, p=.037), the oxygen saturation (F=5.417, p=.007). and the respiration rate (F=7.270, p=.002) showed statistically significant differences in three groups. Conclusion: Based on the results of the present study, K9 acupressure with moxa pellets and P6 acupressure with wristbands (Sea-Band) are considered to be safe and an easy-to-apply intervention to relieve nausea and maintain the level of oxygen saturation and respiration rate in patients undergone unsedated esophagogastroduodenoscopy.
