2017/4/13
Introduction: Venous distention via subsystolic occlusion of the lower limbs may augment ventilation via stimulation of group III/IV afferent neurons.
Purpose: The purpose of this study was to examin...
A Comparison Between Ventilation and Heart Rate as Indicator of Oxygen Uptake During Different Intensities of Exercise
Physical activities light to moderate intensities steady state activities non-steady state activities
2015/5/4
The aim of this study is to compare the relation between ventilation (VE) and oxygen uptake (VO2) [VO2=ƒ(VE)] and between heart rate (HR) and VO2 [VO2=ƒ(HR)]. Each one of the subjects perfor...

A Comparison of Effects of Propofol and Isoflurane on Arterial Oxygenation Pressure, Mean Arterial Pressure and Heart Rate Variations Following One-Lung Ventilation in Thoracic Surgeries
Propofol Isoflurane Arterial One Lung Ventilation Arterial Pressure Heart Rate
2015/10/10
Background:: Hypoxia occurs during one-lung ventilation (OLV) due to the arteriovenous shunt of unsaturated pulmonary venous blood. Hypoxic pulmonary vasoconstriction (HPV) acts as a defense mechanism...
Effects of Altered Airway Function on Exercise Ventilation in Asthmatic Adults

2017/5/23
Variable airway function is a central feature of the asthmatic condition. Thus, habitually active asthmatics are certain to exercise under conditions of variable airway (dys)function. The purpose of t...
Comparison of High Frequency Positive Pressure Mechanical Ventilation (HFPPV) With Conventional Method in the Treatment of Neonatal Respiratory Failure
Respiratory Insufficiency Infant Newborn Ventilation
2015/9/29
Background: Respiratory failure is a major problem in neonatal medicine in all over the world and has different causes. Using mechanical ventilation is one of its major treatments.
The comparison between effects of two general anesthesia techniques;Intermittent apenic technique and continuous controlled ventilation in upper airway Laser therapy
Intermittent apenic technique Laser therapy Continuous controlled ventilation PeteCo2 SpaO2
