Purpose: To find the effects of semi-Fowler's position on the post-operative recovery for patients with laparoscopic abdominal surgery in recovery room. Method: The research was performed by nonequivalent control group non-synchronized quasi-experimental design. The subjects are forty patients who had laparoscopic abdominal surgery in a hospital from Aug. thru Nov. of 2003. Post-recovery scores and $O_2$saturation degree were measured. The experimental group was place in semi fowler's position while the control group was placed in supine position. The homogeneity between the control group and experimental group was analyzed using the Chi-square, and the hypothesis were tested using t-test. Result: 1. The patients in the experimental group placed in semi fowler's position showed significant higher post-recovery scores than those in the control group who were in a supine position. 2. The patients in the experimental group who were in semi Fowler's position showed no significant higher $O_2$ saturation degree than those in the control group who were in supine position. Conclusion: Based on the results described above, it is considered that the semi-Fowler's position might be effective in enhancing the post-operative recovery score of the patients with laparoscopic abdominal surgery in recovery room.

The purpose of this study was to identify the effect of body positioning on $PaO_2$, $SpO_2$, systolic blood pressure, diastolic blood pressure, pulse, and respiration(above all defined physiologic index), of patients with unilateral lung disease. The subjects for this study were eleven patients admitted to I.C.U. of K.H.M.C. with a diagnosis of unilateral lung disease confirmed by chest X-ray and the attending doctor, from January 30th. to April 20th. 1999. A quasi-experimental repeated-measures cross-over design was used to compare three body positions(semi-Fowler's, lateral decubitus with good lung dependent, and lateral decubitus with diseased lung dependent). Each subject spent 30 minutes in semi-Fowler's position and 2 hours in good lung dependent position and diseased lung dependent position. Starting in the semi-Fowler's position, then in the lateral position with the good lung dependent or the diseased lung dependent as assigned in random order. Thirty minutes after each positioning, arterial blood sample was analyzed. Measurements of all physiologic index were recorded at the specified intervals(0, 30, 60 90, and 120 minutes) in good lung dependent and diseased lung dependent position. Statistical comparison of $PaO_2$ value was done using the Wilcoxon Signed Rank Test, and Multivariate repeated-measures analysis of variance was performed to analyse the within-subject effect of two dependent position for 2 hours on the five dependent variables: (1) $PaO_2$ (2) $SpO_2$ (3) systolic blood pressure (4) diastolic blood pressure (5) pulse. The results obtained were as follows: 1. The $PaO_2$ value in the good lung dependent position was significantly higher than the $PaO_2$ value in the diseased lung dependent position(Z=-2.8451, p=.002). 2. The $PaO_2$ value in the good lung dependent position was significantly higher than the $PaO_2$ value in the semi-Fowler's position (Z=-2.6673, p=.003). 3. The difference between the $PaO_2$ value in the semi-Fowler's position and the $PaO_2$ value in the diseased lung dependent position was not significant(Z=-1.2448, p=.10). 4. There were no statistically significance in the trends of physiologic index in the good lung dependent position and the diseased lung dependent position. From the results, it may be concluded that the good lung dependent position is the most effective position for patients with unilateral lung disease that improve oxygenation. Identification of positioning over time may be need further studies.

Purpose: The study was done to investigate whether positioning relieves the back pain and enhances comfort during bed rest after transhepatic arterial chemoembolization(TACE). Methods: A quasi-experimental design with non-equivalent control group non-synchronized design was used. The experimental group was placed semi Fowler's position for the first 2 hours. The following 4 hours the position was rotated hourly between 30 degrees laterally inclined position and a semi Fowler's position. The control group was maintained in a supine position for the 6 hours. Data were analyzed using t-test, $x^2$-test, Fisher's exact test and repeated measures ANOVA. Results: 1) Back pain intensity significantly decreased in the experimental group compared to the control group. 2) Comfort level significantly decreased in both groups, but there was no significant difference between the two groups. 3) There were no hematoma and bleeding complication in either group. In addition, there was no significant difference in urinary retention between the two groups. 4) Analgesics were less frequently taken by the experimental group. Conclusion: These results suggest that positioning relieves back pain without causing an increased incidence of hematoma and bleeding formation after TACE and this nursing intervention might help patients be more comfortable during the treatment of TACE.

Purpose: This study was to test the effects of the positional change on low back pain, discomfort, and bleeding complications during the period of bed rest following transarterial chemoembolization (TACE). Methods: The research design for this study was a non-equivalent control group quasi-experimental design. The participants were 23 patients for the experimental group, and 23 patients for the control group. The experimental group received positional change of taking the semi-Fowler's position and the 30-degree lateral position alternatively during the period of bed rest after TACE for 4 hours at one-hour intervals. The control group maintained the supine position continuously during the period of bed rest after TACE. Results: There were statistically significant differences in low back pain and discomfort between the experimental and the control group after intervention. And no significant difference was found in bleeding complication between two groups. Conclusion: The results of the study suggest that the positional change is an effective nursing intervention to reduce low back pain and discomfort without increasing the risk of bleeding after TACE.

Purpose: This study was to develop an algorithm for emergency nursing care of dyspneic patients. Methods: This methodological study was done through reviews of medical records and literatures, checklists of emergency nursing care for dyspneic patients, interviews with nurses, and experts' validity. Results: Firstly, the initial assessment confirmed the identification of airway patency, accessory muscle usage, RR, $SpO_2$, v/s, skin color, and mental status. Immediate emergency care provided oxygen, checked ABG, EKG, and chest X-ray, established a semi-fowler position, maintained IV routes, administered medication orders, and conducted careful monitoring. Secondly, if the patient exhibited $SpO_2$ of less than 90%, the nurse considered the patient's condition to be aggravated. Thirdly, if the patient showed improvement of more than 90% $SpO_2$, the nurse administered secondary assessment and carried out specific nursing care. However, if the patient continuously showed $SpO_2$ of less than 80%, the nurse assisted the intubation and then executed ventilator therapy. Conclusions: This study suggests that the algorithm is an effective decision tool and utilizing the algorithm is expected to improve the emergency nursing care for dyspneic patients.

Background: The international organization for standardization (ISO) 80601-2-61 dictates that the accuracy of a pulse oximeter should be assessed by a controlled desaturation study. We aimed to characterize the relationship between the fraction of inspired oxygen (FiO₂) and peripheral oxygen saturation (SpO₂) using a turnover model by retrospectively analyzing the data obtained from previous controlled desaturation studies. Materials and Methods: Each volunteer was placed in a semi-Fowler's position and connected to a breathing circuit to administer the hypoxic gas mixture containing medical air, oxygen, nitrogen, and carbon dioxide. Volunteers were exposed to various levels of induced hypoxia over 70-100% arterial oxygen saturation (SaO₂). The study period consisted of two rounds of hypoxia and the volunteers were maintained in room air between each round. FiO₂ and SpO₂ were recorded continuously during the study period. A population pharmacodynamic analysis was performed with the NONMEM VII level 4 (ICON Development Solutions, Ellicott City, MD, USA). Results: In total, 2899 SpO₂ data points obtained from 20 volunteers were used to determine the pharmacodynamic characteristics. The pharmacodynamic parameters were as follows: k_out = 0.942 1/min, Imax = 0.802, IC₅₀ = 85.3%, γ = 27.3. Conclusion: The changes in SpO₂ due to decreases in FiO₂ well explained by the turnover model with inhibitory function as a sigmoidal model.
