Introduction: In hypertensive patients M position (sitting, right arm at the level of heart and both plantar surface of foots on the floor) is the standard position for measurment of blood pressure since it reveals the “true” pressure. Materials and

Methods: It is a quaziexperimental study that compares effect of different positions of limbs on blood pressure of hypertensive patients. The sample size was consisted of 100 hypertensive patients. A questionnaire and a check list for systolic and diastolic blood pressure of the patients in different positions were used. One researcher collected all of the data. At first demographic data, weight and hight were recorded. After 5 minutes in sitting position in 3 different comparing positions, M (sitting, right arm at the level of heart and both plantar surface of foots on the floor), A (sitting, right arm hanging beside the body and both plantar surface of foots on the floor) and B (sitting, right arm hanging beside the body and right foot on the left knee), blood pressure was measured and recorded. The study methods included interview and physiologic measurement. The paired t-test for related measure was applied in order to analyse the data.

Results: The results showed that the difference of mean systolic and diastolic blood pressure in “A & M”, “B & M” and “B & A” positions was significant (paired t test, p<0.0001) and the mean of systolic and diastolic blood pressure in “A” position was more than “M” position, “B” position was more than “M” position and “B” position was more than “A” position.

Conclusion: According to the findings of this study, “B” position has the greatest effect and “M” position has the lowest effect on increasing the systolic and diastolic blood pressure. This research indicated that attention to the limbs position during the measurement of blood pressure is very important.

Background & Aim: One of the nurses' roles in patient care is frequent position change in patients undergoing mechanical ventilation. Because of attaching many lines and tubes to these patients, they are in supine or lateral positions most of the time. Nurses prefer these positions due to making care simple. Many studies have shown that prone position has positive effects on oxygenation and ventilation. However, other studies have shown some negative effects. The aim of this study was to determine the effect of prone position on oxygenation in patients undergoing mechanical ventilation.

Methods & Materials: In this quasi-experimental study, 36 patients were selected using simple sampling method. Data were collected using a questionnaire and oxygenation data sheet. First, patients were put in supine position. After 30 and 120 minutes, oxygenation was assessed. Then they were changed to prone position and after 30 and 120 minutes oxygenation was reassessed. Data were analyzed using paired t test, spearman, and fisher exact tests in SPSS.

Results: The results indicated that there was significant differences between prone position and the amount of spo2 and sao2 oxygenation after 30 and 120 minutes (P<0.001).

Conclusion: Prone positioning was effective on oxygenation after 30 and 120 minutes so nurse should use this position in their care.

Background & Aim: The prevalence of cardiovascular diseases is high in most of the countries. Cardiac catheterization is a routine diagnostic test for coronary heart diseases. In order to minimize the post-procedure complications, patients are restricted to bed for 8-24 hours in flat position. The aim of this study was to assess the effect of changing position and early ambulation on back pain and the amount of bleeding after cardiac catheterization.
Methods & Materials: In this quasi-experimental study, 90 patients undergoing diagnostic angiography were selected using convenience sampling method in Shariati hospital. The patients were allocated in two intervention and control groups. The control group remained in supine position for 8-24 hours and the sandbag remained for eight hours. The patients&apos position in the intervention group was intermittently changed during the first hour after catheterization. The head of bed was set at 15 degree angle. In the second hour, the position changed to flat and the head of bed raised to 30 degree. In the third hour, the head of bed angle was set in 45 degree. In the first three hours sandbag was placed in catheter insertion site. After the third hour, patients could rest in any position (15-30 degree). Patients were ambulated in the sixth hour. Back pain intensity and level of bleeding were assessed immediately after admission, in the sixth, 24^th hour and after the seventh day of catheterization.
Results: The results indicated that there was no statistically significant difference in age, gender, education level, back pain intensity, and the level of bleeding immediately after the catheterization. Back pain intensity was lower in the intervention group than the control one after 6 and 24 hours of catheterization (P<0.001). There was no statistically significant difference between the intervention and control groups in the level of bleeding after 6 hours, 24 hours, and seven days of catheterization (P>0.05).
Conclusion: Patients should be allowed to change their positions in bed cardiac catheterization. Patients can be ambulated earlier (in the sixth hour) after cardiac diagnostic catheterization.
