Introduction: One of the main treatments of chronic otitis media with effusion is ventilation of the middle ear with a ventilation tube (VT). The objective of this study was to determine the incidence and the types of VT complications in children with otitis media with effusion in Ahwaz. Materials and Methods: In this prospective study, the medical records of 208 children (52 male and 35 female...

Twelve healthy term infants were examined at the median ages of 2 1/2 and 26 hours. Their alveolar ventilation, efficiency of ventilation, functional residual capacity, and lung nitrogen elimination patterns were studied by means of a computerised nitrogen wash out method. The results showed that alveolar ventilation and functional residual capacity increased over the period studied. At the sam...

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 dysfunction in critical ages of growth development. the location of the vt insertion varies in different studies; the differences are in recovery rates and sequelae of vt insertion. this study is perf...

This study explores the assumption that 81mKr static images represent regional ventilation. Dynamic acquisition of 81mKr ventilation images permits creation of time-activity curves and the possible separation of the confounding influences of ventilation and volume. By using a two-compartment gas mixing lung phantom, the results demonstrate that both total and tidal 81mKr are closely related to ...

a bstract             mechanical ventilation is one of the major supportive interventions in intensive care units. weaning the patients from mechanical ventilation and its related criteria are of great importance due to the related complications. as there is no comprehensive standard to allocate the time of weaning and due to lack of local research in this fi eld, development of a comprehensive...

background and objectives: the weaning procedure of mechanical ventilation in many patients is a difficult and long process and increases the time of mechanical ventilation. there are numerous ways to achieve this goal. one common way is using cpap-ventilator. considering the lower price of blender-humidifier compared to cpapof ventilator and the limited number of studies in this field, this st...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

Mouth-to-mouth ventilation is often refused by laypersons because of hygienic reasons. Supraglottic airway devices (SADs) might reduce the adverse effects of mouth-to-mouth ventilation. We tried to verify the possibility for untrained laypersons to use SADs properly after having read written instructions only. The participants were told to ventilate a manikin using a laryngeal tube (LT). The ti...

OBJECTIVE The optimum strategy for mechanical ventilation in a child with status asthmaticus is not established. Volume-controlled ventilation continues to be the traditional approach in such children. Pressure-controlled ventilation may be theoretically more advantageous in allowing for more uniform ventilation. We describe our experience with pressure-controlled ventilation in children with s...
