Background: 3DCRT (three-dimensional conformal radiotherapy) and IMRT (intensity-modulated radiotherapy) has provided us with tools to delineate the radiation dose distribution of tumor targets. However, the precision of radiation can be compromised by respiratory motion, which usually limits the geometric and dosimetric accuracy of radiotherapy. The purpose of this study is to evaluate the imp...
BACKGROUND Respiratory rate (RR) is an important vital sign which is strongly correlated with in-hospital mortality. At the same time, RR is the most likely vital sign to be omitted when assessing a patient. We believe that one reason for this could be the difficulty in measure the RR, since it is not read off a monitor, but counted manually. Also there is the possibility of assessment bias and...
Background: Physical Activity improves the functional capacity of circulatory system with minimum myocardium stress. Objectives: This study was designed to assess exercise modulation and sex difference blood pressure (BP), respiratory rate (RR) pulse (PR) selected undergraduate students. Design: involved 360 students using convenience sampling method, aged between 18 35 years. Lecturers postgra...
introductionchildren with severe asthma attack are a challenging group of patients who could be difficult to treat and leading to significant morbidity and mortality. asthma attack severity is qualitatively estimated as mild, moderate and severe attacks and respiratory failure based on conditions such as respiration status, feeling of dyspnea, and the degree of unconsciousness. part of which ar...
The majority of scientific papers on the subject of respiratory patterns in insects have dealt with the discontinuous gas-exchange cycle (DGC). The DGC is characterized by the release of bursts of CO(2) from the insect, followed by extended periods of spiracular closure. Several hypotheses have been put forward to explain the evolutionary origin and physiological function of this unusual respir...
بررسی تأثیر موسیقی بر پاسخ های قلبی- تنفسی و شاخص درک تقلای مردان ورزشکار هنگام فعالیت ورزشی فزاینده
Background: The purpose of this study was to study the effect of fast music rhythm on cardio- respiratory responses and perceived exertion rate during incremental exercise in athletic men. Methods : Ten athlete males (age: 22 2.44 yr, height: 176 ± 6.72 cm, weight: 69.4 ±4.65 kg), voluntarily performed Bruce protocol until exhaustion with fast music condition, and cross-over format, with 72...
