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...
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...
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...
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...
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.
Introduction: Laser beam due to finest of incision and reduction of postoperative complication, facilitates airway surgery, but at the same time it increases the danger or firing and the airway manage...
Background: Cuffed pharyngeal tube is a device designed for ventilation of anesthetized patients. CPT has advantages over face mask including: maintaining of face mask can be difficult and boring afte...
Ventilation tube (VT) insertion is the most common otologic operations performed in children, which has great importance in recovery and prevention of hearing loss in children with Eustachian tube dys...
The effect of liquid ventilation on pulmonary vascular resistance was studied in an isolated cat lung preparation in situ. Lungs were perfused with whole blood from a donor cat at a constant flow of 1...
A closed-circuit fluorocarbon oxygenation system was designed and incorporated into an existing liquid breathing system (LBS) to allow measurement of an animal's oxygen consumption during liquid venti...
Seven subjects had spirometric studies during head-out immersion before and after working at depth in coral research. Under the variable environmental conditions of a field study the seven subjects de...
Four to six subjects performed maximal voluntary ventilation (MVV) and forced expirations during rest, exercise (50, 125, and 200 W), and inhalation of air and CO2 and air at rest while submerged at p...
Body cooling, respiratory heat loss, and the physiological effects of liquid ventilation at various temperatures were studied in 10 adult cats with applications to the deep sea diver. The animals were...
The liquid-filled lung preparation has provided physiologists with a unique technique for varying the physical properties of respiratory media and studying their effect on basic pulmonary processes. M...
