BACKGROUND: Transnasal esophagogastroduodenoscopy (EGD) without sedation has been reported to be safe and tolerable. It has recently been used widely in Japan for the detection of upper gastrointestinal disease. Alternatively, transoral examination using a thin endoscope has also been reported to be highly tolerable.OBJECTIVE: To examine the cardiocirculatory effects of transoral versus transnasal EGD in an attempt to determine the most suitable endoscopic methods for patients ≥75 years of age.METHODS: Subjects who underwent monitoring of respiratory and circulatory dynamics without sedation during endoscopic screening examinations were enrolled at the New Ooe Hospital (Kyoto, Japan) between April 2008 and March 2009. A total of 165 patients (age ≥75 years) provided written informed consent and were investigated in the present study. Patients were randomly divided into three subgroups: UO group – thin endoscope; SO group – standard endoscope; and UT group – transnasal EGD. Percutaneous arterial blood oxygen saturation, heart rate and blood pressure were evaluated just before EGD and at five time points during EGD. After transnasal EGD, patients who had previously been examined using transoral EGD with a standard endoscope were asked about preferences for their next examination.RESULTS: There were no statistical differences in the characteristics among the groups. Percutaneous oxygen saturation in the UT group showed a transient drop compared with the SO and UO groups at the beginning of the endoscopic procedure. Heart rate showed no significant differences among the SO, UO and UT groups; Systolic blood pressure in the UO group was lower immediately after insertion compared with the SO and UT groups. The rate pressure product in the UO group was comparable with that in the UT group during endoscopy, and the SO group showed a continuously higher level than the UO and UT groups. More than one-half (54.4%) of patients were ‘willing to choose transnasal EGD for next examination’.CONCLUSIONS: For elderly patients, unsedated transnasal EGD failed to show an advantage over unsedated standard endoscopy. Transoral thin EGD was estimated to be safe and tolerable.

Objective To study the safety and feasibility of implementation of precise radiotherapy with inducement of an apnea-like condition. Methods Two patients with lung tumors underwent precise radiotherapy under an apnea-like condition. The apnea-like condition was induced 11 times between the two patients for tumor localization and treatment. The changes in the blood oxygen saturation, blood pressure, heart rate, and end-tidal carbon dioxide during the apnea-like periods were observed, and the incidence of adverse reactions was recorded. Results The average apnea-like time was 6.2 minutes (range, 3–9 minutes), and the average radiotherapy time was 4.6 minutes (range, 1–7 minutes). The lowest blood oxygen saturation level was 97%, with a change of <1%. The heart rate and average arterial blood pressure increased during the apnea-like periods. Contact sores appeared on the patients’ posterior pharyngeal wall after the first apnea-like period; no other adverse events occurred. Conclusion Precise radiotherapy under an apnea-like condition is safe and feasible for patients with lung tumors.

Pulse oximetry has gained widespread use in neonatal oxygen monitoring. However, because specific morbidity in neonates has been related to abnormal levels of oxygen partial pressure (Pao2), it is essential to demonstrate that pulse oxygen saturation values (Spo2) are highly accurate and reflect with precision the simultaneous Pao2. In this report, data is presented that describe the accuracy of the Ohmeda Biox 3700 pulse oximeter. Spo2 was highly correlated with arterial blood oxygen saturation (r = .99) measured on arterial (catheter) blood using a two-wavelength Radiometer OSM2 Hemoximeter. When compared with Pao2, Spo2 values of 92% ± 3% (mean ± range) excluded all of the measured Pao2 values less than 45 mm Hg and greater than 100 mm Hg. Spo2-tcPo2 (transcutaneous Po2) and Spo2-Pao2 (catheter or percutaneous arterial Po2) correlations showed that bronchopulmonary dysplasia, percutaneous arterial sampling, and nipple feeding skewed the tcPo2 but not the Pao2 correlations with Spo2, indicating that Spo2 is not sensitive to peripheral factors that affect tcPo2. Spo2-Pao2 correlation was not affected by gestational age. A high degree of accuracy of Spo2 values and Spo2 prediction of normal appearing Pao2 values are defined by these results.

Use of technology in healthcare is growing importance as a result of the tendency to acquire chronic disease like heart attack and high blood pressure. Heart rate and blood oxygen saturation is a couple of such biometrics that is monitored in this project to provide information regarding the health of the body. By measuring the intensity change of light transmitted through tissue due to arterial blood, heart rate is measured. Furthermore, oxygenated blood has different light absorption characteristics than deoxygenated blood under red and infrared wavelengths. Comparing the absorptions produce an estimate of the oxygen saturation of blood. The purpose is to examine how heart rate and the oxygen saturation of subject is measured from finger and then processed and displayed. The design, is small in size, easy to use, allows a non- invasive, real time method to provide information regarding health. This enables an efficient and economical means for managing the health care. This document is intended to be used by engineers, medical equipment developers, anyone related to medical practice and interested in understanding the operation of pulse oximeter and heart rate monitoring system.
