Anxiety in patients under Coronary Angiography leads to changes in cardiopulmonary parameters. The current study aimed to compare the effect of virtual reality and rhythmic breathing on the physiological parameters of patients undergoing coronary angiography.

In this clinical trial, 90 patients admitted to the cardiac care ward were studied in 2019-2020. They were selected by convenience sampling and randomly allocated into three groups: virtual reality, rhythmic breathing and control. Virtual reality and rhythmic breathing groups received intervention and the control group received routine care. Systolic and diastolic blood pressure, heart rate; respiration rate and arterial oxygen saturation were measured before, half an hour and one hour after the intervention in three groups.

Findings revealed that the pattern of changes of the mean of respiration and heart rate was significantly different in all the three stages of measures in the three groups (P˂0.001). In the case of systolic and diastolic blood pressure and arterial oxygen saturation, the pattern of changes did not show a significant difference in the three groups (P>0.05).

The use of these methods can lead to modification of some physiological parameters. This means nurses can use these methods as non-invasive, without side effects, cheap and applicable methods in order to improve patients’ physiological parameters.

Data were analyzed by SPSS-16 using repeated measures analysis of variance and Chi-square.   

The results showed that the pattern of changes of the mean of respiration and heart rate was significantly difference in three times of measures in the three groups (p = 0.001). In the case of systolic and diastolic blood pressure and arterial oxygen saturation, the pattern of changes did not show a significant difference in the three groups (p >0.05).

The use of these methods can lead to modification of some physiological parameters, so the nurses can use these methods as non-invasive, without side effects, cheap and applicable to improve patients’ physiological parameters.

Workers in many industries (oil, gas, petrochemicals, cement, steel, glass, and textile) and even at home, offices are exposed to various noises with different frequencies causing hearing and non-hearing impairments. The present study aimed to investigate the effect of noise at different frequencies on physiological responses and cognitive functions of oil drilling industry personnel and urban gas pressure reducing station.

This descriptive-analytical study was conducted in 2019 with the participation of 50 employees of oil drilling rigs (low frequency noise) and city gas pressure reducing stations (high frequency noise). Physiological parameters examined included (heart rate, systolic and diastolic blood pressure, and tympanic body temperature). The participantschr cognitive functions were assessed using advanced reaction timer, continuous performance and working memory tests before, during and after the activities. Also, the relationship between variables was investigated using structural equation modeling (SEM).

The study results indicated that was exposed to noise at high and low frequencies, physiological responses, including heart rate, systolic and diastolic blood pressure and tympanic temperature increase, and this increase was statistically significant (p <0.001). Exposure to noise also has a negative effect on cognitive functions (such as working memory, sustained attention, and advanced reaction timer).

Low frequency noise has a greater effect on physiological responses and cognitive function than high frequency noise. Obviously, further research in this area is suggested in the industry.

Despite the negative opinions of intensive care unit staff about the presence of the family next to the patient, many studies have shown that family-centered care can be effective in meeting this need as well as the comfort and physiological parameters of patients. The purpose of this study was to determine the effect of family-centered care on physiological parameters of patients of brain injury patients admitted to intensive care unit in selected hospitals in Isfahan, in 2020.

This study was a quasi-experimental study. A total of 30 brain injury patients referred to selected hospitals in Isfahan in 2020 were included in the study by available sampling and were assigned to two groups of 15 intervention and control by random assignment of permutation. In the intervention group, the patientschr('39') first-degree families were present at the patientchr('39')s bedside for 3 days and twice a day at 10:00 AM and 3:00 PM and performed a family-centered care program. The control group received routine ward care. Physiological parameters were recorded and measured 15 minutes before, during and after care.

The findings showed that the mean of physiological parameters such as heart rate, systolic blood pressure, and arterial blood oxygen saturation in the intervention group was significant difference than the control group (P< 0.05). However, there was no significant difference in physiological parameters such as diastolic blood pressure of the intervention group (P >0.05).

The results of this study showed that family-centered care on the patientchr('39')s bedside causes significant changes physiological parameters that cause relaxation in the patient and balance in the patientchr('39')s physiological parameters. Therefore, it should be possible for the closest family member to be present at the patientchr('39')s bedside at the appropriate time with adequate training in family-centered care.

Determining methods for assessing heat stress in different work environments is one of the major challenges for researchers in this field. The purpose of this study was to validate WBGT index and heat pressure assessment (HPA) by some physiological responses in Iranian South Oil Company.

This descriptive-analytical study was carried out on 154 employees of Kharg, Asalouyeh and Mahshahr oil terminals recruited from three different working conditions including indoor, outdoor and rest environments in the summer. The amount of heat stress in the workplace was evaluated by WBGT index HPA method. To meet this purpose, the environmental parameters i.e., temperature, wet temperature, radiation temperature, relative humidity, water vapor pressure and air flow rate were determined. In addition to the direct reading method by the WBGT meter, ISO 7243 was used to calculate the WBGT index. In order to validate the heat stress indicators, physiological parameters of oral temperature, tympanic temperature and work metabolism were measured.

The results of paired sample t-test showed a significant difference between WBGT index and HPA in indoor and outdoor environment (P<0.05). Moreover, there was a significant difference between the physiological indices of oral and tympanic temperatures and work metabolism in the indoor and outdoor environment (P<0.05). Furthermore, the correlation test was significant between WBGT index as an independent variable and HPA as a dependent variable (P<0.05)  and showed a high correlation (R2=0.914) between WBGT index with oral temperature and tympanic temperature . Also, the rate of work metabolism was significantly related with the aforementioned parameters (P<0.05) and was equal to R2=0.423, R2=0.335, R2=0.552, respectively. The correlations were also significant between HPA with Oral temperature, tympanic temperature and work metabolism (P<0.05)and were equal to R2=0.632, R2=0.605, R2=0.557, respectively. The results showed also that the correlation rate between the HPA with physiological parameters is stronger than that between physiological parameters with the WBGT index.

This study showed that WBGT and HPA methods are useful for assessing the heat stress of Iranian South Oil Company. Also, the HPA method is more reliable for assessing heat stress in these regions.

 Anxiety is one of the most common accompanying symptoms in pregnant mothers and is associated with adverse maternal and neonatal consequences. The aim of the present study was to examine the impact of mindfulness-based counseling on the levels of anxiety during the pregnancy period and on newborns’ physiological parameters.

 This study was a semi experimental pretest-posttest with a control group. Sixty primiparous pregnant women who referred to the health clinics of Kermanshah were selected using convenient sampling and were randomly assigned into either experiment or control group. The control group received routine prenatal care, and the experimental group underwent eight groups mindfulness-based counseling sessions (60-90min) twice a week, in addition to routine prenatal care. Before, immediately after and one month after the intervention, both groups completed the Vandenberg Gestational Anxiety Questionnaire. In addition, after delivery, the newborns’ physiological parameters (weight, height, gestational age and Apgar score) checklist was completed. The data was analyzed using Mann-Whitney, Independent t-test, and Friedman's tests using SPSS- 25.

 Pregnancy anxiety was not significant between the control and intervention groups before the intervention (p = 0.694). However, immediately and one month after the intervention the difference was significant (p≤ 0.001). After delivery, the physiological parameters of infants born to women in the intervention and control groups were not significantly different.

 According to the study results, mindfulness-based counseling was effective in reducing pregnancy anxiety, but did not affect the physiological parameters of newborns at birth.

One of the challenges of cesarean section is the control of pain in the mother. Whether neonatal-related complications occur with pethidine if the mother's pain is relieved? or not ,   It should be given more attention.
The aim of this study was to investigate the effect of pethidine on physiological parameters of newborns of Non-emergency cesarean section mothers in spinal anesthesia in Amir al-Momenin Hospital of Gherash in2017.

An experimental clinical trial study was performed on 116 neonates Whose mothers underwent non-emergency cesarean section by spinal anesthesia,. Study mothers randomly assigned in intervention and control groups with binary blocks design. Intervention included routine care (100mg of diclofenac suppository) for control group and a single dose of 100 mg pethadine administered intervention group by an anesthetist as an intravenous infusion.  The physiological parameters of neonates in both groups were recorded by the researcher and her assistant within 48 hours of hospitalization.

Despite the fact that the mean heart rate of neonates in the group of pethidine (141.12) during the first 48 hours of birth was higher than that of the control group (40.41), the independent t-test did not show any significant difference between the two groups in terms of the mean of neonatal heart rate (p = 0.354) and the percent of arterial blood oxygen (p = 0.580). The mean of respiratory rate in the 48 hours of birth in the control group was higher than that of the pethidine group (p = 116). The mean of body temperature of infants in the two groups was negligible (p = 0.335).

The administration of single dose of pethidine on the physiological parameters of newborns of non-emergency cesarean mothers by spinal method had no statistically significant effect.

One of the most common methods of treatment in alternative medicine is reflexology foot.

The aim of this study was to determine the effects of foot reflexology on fatigue, pain and physiological parameters of patients after coronary angiography in BaqiyatallahAzam hospitals in Tehran, Iran.

The study is a randomized controlled trial which contains 70 patients who are admitted in Critical Care Unit wards2016. Who entered in the study very easily, then divided randomly into two equal control and experimental groups. In the intervention group after measure and recorded basic information, prepared and warmed up the foot.  After the massage, foot reflexology, pain and fatigue in patients used the visual analog scale pain and fatigue and physiological parameters, including heart rate, respiratory rate, systolic and diastolic blood pressure using a pressure gauge and a clock with a second hand on two occasions 2 hours and 4 hours after foot reflexology measured. It was used statistical test Chi-square test, Fisher exact test, Independent t test and paired t test and Bonferroni test for analysis.   

Results showed significant differences in pain and fatigue and systolic and diastolic blood pressure levels after the intervention among both groups (p<0.001), but wasn’t significant differences in heart rate, respiratory rate after the intervention among both groups (p<0.05).

According to this study, foot reflexology massage, is a useful nursing intervention.

Improving the respiratory function of patients for weaning mechanical ventilation is one of the caring challenges in intensive care settings. Acupressure maybe improves physiological criteria. Therefore, this study aimed to determine acupressure therapy on physiological criteria in female patients being weaned from mechanical ventilation.

This randomized controlled trial was conducted in intensive care units of a teaching hospital affiliated to Qazvin University of Medical Sciences, Qazvin, Iran. Eighty patients were recruited based on inclusion criteria and randomly allocated to experimental (n=40) and placebo (n=40) groups. While the experimental group received acupressure for 20 minutes and placebo group received pressure only on the thumb. Physiological checklist (respiratory rate, heart rate, and oxygen saturation and mean blood pressure) recorded in the interval before, immediately, and 20 minutes after the intervention, on the T-piece, after extubation, 20 min after extubation. Data were analyzed using descriptive and inferential statistics and analyzed using SPSS- v 20.

After the intervention, respiratory rate and mean blood pressure were not significantly different between the groups (P > 0.05). However, ANOVA test showed that the heart rate and oxygen saturation were significantly different between the groups (P < 0.05).

Implementation of acupressure can have positive effects on physiological criteria in female patients being weaned from mechanical ventilation and is recommended as a non-pharmacological intervention.
