hypoxemia under certain conditions. However, the relationship between pulmonary anesthetic administration and HPV remains controversial. In conclusion, global effects of inhalation induction with sevoflurane at high concentrations may cause oxygen desaturation in lungs that are normally ventilated with 100% oxygen, potentially resulting in global inhibition of HPV. However, these conditions may...

We have compared the effects of inhalation of aerosolized surfactant on experimental acute respiratory distress syndrome. Escherichia coli endotoxin (55 (SD 20) mg kg(-1)) was injected into the tracheas of 36 adult rats anaesthetized and mechanically ventilated with pure oxygen. When the Pa(O(2)) decreased to 11.3 (3.3) kPa, the animals were randomly subjected to inhalation of aerosolized modif...

Little is known about the oxygen cost of caring for infants and older adults. Many people perform these activities so it is useful to know the energy cost and if the activities are of sufficient intensity to contribute to meeting physical activity recommendations. The purpose of this study was to assess the oxygen cost of four care-related activities in the Compendium of Physical Activities. Ni...

Inhaled nitric oxide (NO), at a concentration of 80 ppm, counters the increase in respiratory resistance (Rrs) induced by methacholine, but fails to prevent a reduction in lung compliance (Crs) in a rabbit model. This study reports the effects of 3, 30 and 300 ppm of inhaled NO. New Zealand White rabbits were intubated and mechanically ventilated with 30% oxygen during neurolept anaesthesia. Me...

BACKGROUND An aerosol of budesonide inhalation suspension is delivered when used with various jet-nebulizer/compressor combinations. The constant introduction of new nebulizer/compressor combinations raises the question of whether the performance of these match the performance of existing devices. The aim of this study was to determine in vitro the inhaled mass and aerosol characteristics of bu...

Objective. Although some factors that may influence hospitalization of COVID-19 patients are already known (hypocalcaemia and hyponatremia, bilateral pneumonia), there is a number other potential predictors were not investigated previously. The aim our study was to investigate further the length among with COVID-19. Methods. designed as observational, retrospective cohort investigation associat...

A patient suffering from acute smoke inhalation also had a long medical history that included reflex sympathetic dystrophy syndrome of the left foot and ankle. The entire foot and ankle were tender and cool to palpation; range of motion was severely reduced. She was referred for hyperbaric oxygen therapy, and 15 min into the the first treatment (46 min at 60 fsw) she reported a lessening of the...

A 61-year old man presented with a sudden onset of breathlessness. The total left pneumothorax was overlooked on the initial chest radiograph. One month later, the patient had a partial pneumothorax less than 20% on the radiograph, although he did not receive any therapy against pneumothorax, such as oxygen inhalation or needle aspiration. After the observation for one month, the lungs totally ...

During the first month, this infant vomited immediately after a teaspoon of scrambled egg on two occasions. The third time, at two months of age, he rapidly developed anaphylaxis after an egg-based feed: urticaria, edema of the ears, dyspnoea, wheezing, grunting, laryngeal edema, and delayed refill time. Intramuscular epinephrine and hydrocortisone, inhaled oxygen, and intra-osseous fluids were...
