The Relationship

Background: The relationship between increase in body temperature, heart rate, and respiratory rate has only been studied in young, healthy subjects. Aim: To show the changes in heart and respiratory rate associated with fever in acutely admitted medical patients. Design: A prospective observational cohort study Methods: Vital parameters from 4,493 patients were retrospectively extracted. Linear and multiple variable regression analysis was used to calculate the change in heart and temperature rate for every degree rise in temperature (i.e. ΔHR/°C and ΔRR/°C) in the entire study group and in those with low (<36.1°C), normal (36.1-38°C) and high (>38°C) body temperatures. Results: The ΔHR/°C and ΔRR/°C was 7.2±0.4 beats per minute (bpm) and 1.4 ±0.1 (1.2 to 1.62) breaths per minute (bpm). Adjusting for age, oxygen saturation and mean blood pressure, the results were 6.4±0.4 (5.7 to 7.1) bpm and 1.2±0.1 (1.0 to 1.4) bpm. In low, normal and high body temperature the ΔHR/°C were 2.7±1.9, 6.9±1.9 and 7.4±0.9 bpm, respectively; for ΔRR/°C the values were -0.5±0.5, 1.5±0.5 and 2.3±0.3 bpm, respectively. Conclusions: We only found a modest association between fever and changes in heart rate and respiratory rate.

The Relationship

Addressing the emotional and mental health of the bedridden elderly is necessary as they are more likely to be depressed being isolated and dependent on a caregiver for a prolonged time. Several studies have been carried out to identify the mental stress of patients through their skin conductivity. The variations in the sympathetic nervous system reflect the emotional state of a person. This is demonstrated by the Galvanic Skin Response and thus can be used as a denotation of psychological or physiological arousal. Such arousal causes the blood capillary dilation, increment of sweat gland activities making the skin further conductive to electricity. In this study we develop a sensor module composed of a Galvanic Skin Response sensor for the bed ridden elderly and identify the relationship between body temperature, heart rate and GSR of them. The experiment is conducted upon 10 bed ridden elderly aged from 60 – 80 years of the Mihinthale region. The observations demonstrate a correlation between the heart rate, body temperature, skin conductivity and the human physiological states.

Background: The World Health Organization (WHO) recommends the use of tachypnea as a proxy to the diagnosis of pneumonia. Objective: The purpose of this study was to examine the relationship between body temperature alterations and respiratory rate (RR) difference (RRD) in children with acute respiratory infections(ARI). Methods:This cross-sectional study included 297 children with age 2-60 months who presented with cough and fever at the pediatric emergency and outpatient clinics in the Department of Pediatrics, Baskent University Hospital, from January 2016 through June 2018. Each parent completed a structured questionnaire to collect background data. Weight and height were taken. Body temperature, respiratory rate, presence of the chest indrawing, rales, wheezing and laryngeal stridor were also recorded. RRD was defined as the differences in RR at admission and after 3 days of treatment. Results: Both respiratory rate and RRD were moderately correlated with body temperature (r=0.71, p<0.001 and r=0.65, p<0.001; respectively). For every 1°C increase in temperature, RRD increased by 5.7/minutes in overall, 7.2/minute in the patients under 12 months of age, 6.4/minute in the female. The relationship between body temperature and RRD wasn’t statistically significant in patients with rhonchi, chest indrawing, and low oxygen saturation. Conclusion: Respiratory rate should be evaluated according to the degree of body temperature in children with ARI. How- ever, the interaction between body temperature and respiratory rate could not be observed in cases with rhonchi and severe pneumonia.

To effectively use vital signs as indicators in children, the magnitude of deviation from expected vital sign distribution should be determined. The purpose of this study is to derive age-specific centile charts for the heart rate and respiratory rate of the children who visited the emergency department. This study used the Korea’s National Emergency Department Information System dataset. Patients aged <16 years visiting the emergency department between 1 January 2016 and 31 December 2017 were included. Heart rate and respiratory rate centile charts were derived from the population with normal body temperature (36 to <38 °C). Of 1,901,816 data points retrieved from the database, 1,454,372 sets of heart rates and 1,458,791 sets of respiratory rates were used to derive centile charts. Age-specific centile charts and curves of heart rates and respiratory rates showed a decline in heart rate and respiratory rate from birth to early adolescence. There were substantial discrepancies in the reference ranges of Advanced Paediatric Life Support and Pediatric Advanced Life Support guidelines. Age-based heart rate and respiratory rate centile charts at normal body temperature, derived from children visiting emergency departments, serve as new evidence-based data and can be used in follow-up studies to improve clinical care for children.

1. Three calves were exposed in a climatic room to an environment of 40° C. dry-bulb and 38° C. wet-bulb temperature for up to 110 min. each day for 1-2 weeks.2. These exposures produced progressive changes in the physiological reactions of the animals to heat:(a) Rectal temperature and skin temperature (for a given time of exposure) declined. In consequence there was a marked increase in the tolerance time, i.e. in the time for which the animals could withstand the hot environment before reaching a rectal temperature of 42° C.(b) Respiratory rate rose earlier and assumed higher levels (for given levels of body temperature).(c) Heart rate decreased markedly.3. These changes are discussed in relation to heat loss and heat production and have been interpreted as reflecting chiefly a reduction in the metabolic heat production of the animals.

     The aim of this study was to evaluate three regimens in induction and maintenance of general anesthesia in local breed bucks and the investigation of the best protocol of them based on different parameters. Eighteen healthy adult bucks weighing (27.50 ± 0.682 kg), aged (1.989 ± 0.135 years) were used. Animals were divided randomly into three equal groups to undergo pre-experiment preparation. All groups were premedicated intravenously with (0.5 mg/ kg) Diazepam, ten min. Later, the induction for first group was done by Propofol (3 mg/kg B.W), second group was done by Ketamine Hcl (2 mg/kg B.W), while in the third group was done by Thiopental sodium (3mg/kg B.W). After intubation with suitable endotracheal tube, maintenance of the three groups was done by (1.3-1.5%) isoflurane and nitrous oxide with oxygen at ratio 2:1. All the three groups underwent the measurement of the following parameters; (Induction, recovery and duration times) Clinical parameters (heart rate, respiratory rate and body temperature); Clinical signs, analgesia, muscle relaxation; Liver enzyme (Aspartate Amino Transferase and Alanine Amino Transferase). The complete randomized design within statistical analysis system (SAS) program were used for statistical analysis as relevant with a significance level set at P<0.05. The results of this study showed that the induction of the anesthesia was smooth and uneventful in all the three groups and recovery time was shorter in 3rd group in comparison with 2nd and 1st groups. The three regimens showed no significant differences in heart rate. The 2nd group recorded a sharp decrease in respiratory rate and body temperature in comparison with 1st and 3rd groups. Analgesia was very suitable in all the three groups. There were significant changes among groups concerning Alanine Amino Transferase and, Aspartate Amino Transferase. It was concluded that all the three protocols were safe and caused no hazard effect on the animals.

The aim of this study was to evaluate the anesthetic effects of xylazine-ketamine (XK), xylazine-tiletamine-zolazepam (XTZ) and tiletamine-zolazepam (TZ) using hematological and biochemical parameters in rabbits. A total of 18 rabbits were divided into three equal treatment groups (n = 6). The rabbits in the XK, XTZ, and TZ groups were administered xylazine (5 mg/kg) and ketamine (50 mg/kg), xylazine (5 mg/kg) and TZ (15 mg/kg), and TZ (15 mg/kg), respectively, via the intramuscular route. Following the injection, their reflexes were tested every 5 minutes. Heart rate, respiratory rate, and body temperature were determined before the injection (0 min) and at 5, 15, 30, 45, 60, 75, 90, and 120 min after injecting the anesthetic combinations. Furthermore, hematological and biochemical (alanine transaminase [ALT], aspartate transaminase [AST], alkaline phosphatase [ALP], bilirubin, blood urea nitrogen [BUN], and urea) analyses were also performed before, during, and after anesthesia administration. The duration of anesthesia and loss of reflexes were significantly longer in the XTZ group than in the other groups. However, in the TZ group, reflexes were remained. Respiratory rate and body temperature decreased in all the groups. Moreover, heart rate reduced only in the XK and XTZ groups, and the hematological parameters of all groups were comparable. Serum AST and ALP levels increased in the XTZ group compared to that in the XK and TZ groups, respectively. However, these increases were within the reference limits. The post-anesthesia serum BUN and urea levels significantly increased in the XTZ group (p &lt; 0.05) compared to that in the other groups. Thus, although the XTZ combination provided satisfactory anesthetic effect in rabbits, it may be nephrotoxic. Therefore, its use for anesthesia induction in invasive renal procedures and experimental nephrotoxicity studies is not advisable..
