OBJECTIVE High-frequency oscillatory ventilation (HFOV) is an emerging ventilatory strategy for adults that has been used successfully in the neonatal and pediatric population. This modality utilizes high mean airway pressures to maintain an open lung and low tidal volumes at a high frequency that allow for adequate ventilation while at the same time preventing alveolar overdistension. With the...

There is controversy over the effect of hypertension in pregnancy on the incidence of neonatal respiratory distress syndrome. We investigated the association between maternal hypertension and the incidence of respiratory distress syndrome in 268 very low birthweight babies of less than 34 weeks' gestation. A lower incidence of respiratory distress syndrome was associated with growth retardation...

Hypoxia (oxygen scarcity) is widespread in tropical freshwaters, particularly in dense swamps, and may be an important factor structuring benthic macroinvertebrate communities. Macroinvertebrates show a diversity of respiratory modes ranging from atmospheric breathing to tracheal gill breathing, and these adaptations affect their ability to use hypoxic water. The objectives of this study were t...

background: application noninvasive ventilation in the patients with exacerbation of chronic obstructive pulmonary disease (copd) reduced mortality. this case-control study was designed to compare efficiency and outcome of non-invasive (niv) versus invasive positive pressure ventilation (ippv) in respiratory failure due to copd methods: the patients were assigned to niv or ippv intermittantly.t...

Background and Objective: Recently, coronavirus has become a major cause of death and hospital admission worldwide. This study was aimed to assess the factors associated with the presentation via ambulance and time to in-hospital death or discharge from the hospital using a multilevel joint modeling approach. Materials and Methods: In this historical cohort study, hospitalized patients with CO...

This manuscript is the result of ethnobotany and ethnopharmacology survey on the Hezar Mountain in SE of Iran. Traditional botanical medicine is the primary mode of healthcare for most of the population of this region. The plants were collected in and around Hezar mountain from 2008-2010. The authors have conducted an interview of total 75 informants; The traditional uses of 92 species belongin...
