A major concern in pediatric dentistry is maximizing risk management through optimal monitoring of respiratory function during sedation techniques, and Pulse Oximeter is one of the most popular devices for these purpose. Pulse Oximeter is non-invasive device for detecting the sensitive fraction between the saturated & desaturated hemoglobin. Several Studies proved that there is no significant difference between the $SpO_2$ and $SaO_2$. In this article, We examined three Pulse Oximeter $(3300MX^{(R)},\;OX90^{(R)},\;BPM200^{(R)})$. The Pulse Oximeter using shorter pulse beat averaging showed more sensitive reaction to the statue of the patient and lower saturation data. We compared pair of Pulse Oximeter applied to one patient at one time. and $BPM200^{(R)}$(using shorter pulse beat averaging) showed statistically low saturation.

Since the operative mortality rate of the Acute aortic dissection has been reducing, a more extensive primary repair of the dissected aorta is preferred for acute aortic dissection to reduce the needs of secondary procedures. We performed a total aortic arch replacement with distal stent-grafting in acute type A aortic dissection. The patient was a 50-years old man. He recovered from the operation and was followed up for 7 months. The pseudolumen in the descending aorta was obliterated with the stent.

As low power, low cost wireless communication technology like Bluetooth, Zigbee, RFID has been put to practical use together with the wellbeing trend, the concern about ubiquitous health care has been greatly increased and u-Health is becoming one of the most important application in the sensor network field. Especially, development of the medical services to be able to cope with a state of emergency for solitary senior citizens and the aged in silver town is very meaningful itself and their needs are also expected to continuously increase with a rapid increase in an aging population. In this paper we demonstrate the feasibility of extracting accurate heart rate variability (HRV) measurements from photoelectric plethysmography(PPG) signals gathered by a ring type pulse oximeter sensor attached to the finger. For this, we made 2 types of ring sensor, that is reflective and pervious type, and developed the remote monitoring system which is able to collect HR data from ring sensor, analyze and cope with a state of emergency.

Dipyridamole is an agent that may be used to noninvasively evaluate coronary artery disease. The effect of dipyridamole infusion its generally related to its induced peripheral vasodilatory effect. In normal person, heart rate is generally increased slightly while blood pressure decrease, but the achieved double product and related myocardial oxygen consumption have no significant change. The purpose of this study is to examine the effect and side effect of dipyridamle, and to compare different response to dipyridamole among the patients. We evaluated 847 patients who underwent dipyridamole stress myocardial SPECT. 93.6% of them had induced hypotension, 0.9% showed no change of blood pressure, 5.5% had increased blood pressure. 8.3% had no change of pulse rate more than 10% of basal pulse rate. Among diabetes, 16.9% was not change of pulse rate, 6.7% in non-diabetes. There was no significant correlation between age and rate pressure product rest(RPPr), in patiens without perfusion defects on SPECT(y=7.1x+ 48.4 r=0.13 p>0.01). As increasing age, RPPs/RPPr was declined(y= -11.6x+68.9 r=0.17 p<0.01), similar results were obtained in patients with perfusion defect. The size of perfusion defect on myocardial SPECT have no correlation between RPPr and RPPs/RPPr. The side effects of dipyridamole included chest pain and chest tightness, headache, abdominal pain, dizzness, nausea, and dyspnea. As increasing age, dipyridamole-induced cardiac work at rest was increased, cardiac response to dipyridamole was decreased.

The purpose of this study was to examine the effects of aroma foot reflexology and foot reflexology on blood pressure, pulse rate and blood lipid level of elderly essential hypertensive patients in a rural area. The research method was a non-equivalent control group pretest-posttest quasi-experimental design and the participants were consisted of 71 elderly patients with essential hypertension who were being registered at C health Clinic(G gun, Chungnam province). Here, we compared experimental group I(aroma foot reflexology) 24 persons, experimental group II(foot reflexology) 27 persons and control group(conventional treatment) 20 persons to measure the effect. The data were analyzed with SPSS/WIN 12.0. The systolic blood pressure(p<.05), the diastolic blood pressure(p<.05), and the pulse rates(p<.01) of experimental group I and II after intervening respectively with aroma foot reflexology, and foot reflexology for 6 weeks were significantly decreased than the control group, but the blood lipid level was no significant difference among 3 groups(p>.05). In conclusion, both of aroma foot reflexology and foot reflexology had positive effects to decrease the blood pressure and pulse rates of the elderly essential hypertensive patients in a rural area and would be utilized as a nursing intervention for them.

In the past decades there has been a growth of interest in the use of stellate ganglion block (SGB) as part of the diagnosis and therapy for the disease of the head, neck and upper extremities. For the evaluation of changes in hemodynamics and temperature of the affected extremity after the SGB, unilateral SGB (either right or left) was performed by local injection of 10 ml of 1% lidocaine without epinephrine in 45 patients (right side SGB: 25, left side SGB: 20) with various diseases. Systolic and diastolic blood pressure, pulse rate and skin temperature of the ipsilateral hand were studied before and 1, 2, 3, 4, 5, 10, 15, 30 and 60 minutes after the block. The results were as follows: 1) Changes of blood pressure: Systolic and distolic blood pressure after either right or left side SGB showed no statistically significant change. 2) Changes of pulse rate: While the left side SGB showed a mild decrease without statistical significance, the right side SGB showed a statistically significant decrease at 30 and 60 minutes after the block (p<0.05). 3) Changes of skin temperature of the blocked hand: Either side SGB produced a gradual increase in temperature with time and showed statistical significance from 10 minutes in the left side block (p<0.01), and a from 10 minutes after the block in the right side (p<0.01). Both sides SGB showed a maximal increase at 30 minutes after the block and a small decrease at 60 minutes after the block compared to the 30 minutes value. 4) Despite the successful SGB. 4 of 45 patients failed to produce a significant increase in skin temperature on the affected upper extremity. In conclusion, unilateral SGB with 1% lidocaine at the 6th cervical vertebral level is a safe method for use on an outpatient basis, and an increase in skin temperature in the affected upper extremity is necessary to confirm the successful therapeutic effect on disease of the upper extremity.

Purpose: The purpose of this study was to evaluate the effect of the subjects after visiting the Gyorae forest on the activity of the autonomic nervous system. Methods: Before and after the forest bath, it was measured using a ubiquitous machine. Results: After the bath there was no significant difference in the sympathetic nerve activity (LF) of the control group, but the difference was significant in the experimental group by increasing (p<.038), and in the variance analysis, there was a significant difference between the groups (p<.014), between pre-and post-bath (p<.026), and also between the groups and pre-and post-bath (p<.018). The changes in parasympathetic activity (HF) were not significant in both the control and experimental. In the LF/HF ratio, the experimental group was significantly increased, and in the analysis of variance, there was also significant difference between group and before and after bath (p<.04). Mean pulse rate in the experimental group was a significant increase after bath (p<.026). In the change of pulse standard deviation, the value of the control and the experimental groups by variance analysis was a significant difference between the groups (p<.014). There was no difference between the mean values of the control and the experimental groups in the change of mean heart rate deviation. Conclusions: The autonomic nervous systems were activated after Gyorae forest bathing, where may be useful place for healing.
