welders may suffer from welding fumes generated during the process if the ventilation systems are improperly applied. the objective of the present work was to study the mitigation of air pollutants at welding stations, using different ventilation scenarios. four air pollutants including iron oxide, respirable dust, ozone, and carbon monoxide were measured during four different ventilation scena...

Background: Bungarus caeruleus (common krait) bite during monsoon season is common in northwest India. Respiratory failure is responsible for high mortality in the victims. In this study we report our experience with manual ventilation using bag valve mask (BVM) in patients with neuroparalysis due to common krait bite.  Methods:This prospective study was conducted between June 2009 and December...

conclusions: rsbi and apache ii score in patients with copd exacerbation are of the ability to predict niv requirement, as a predicting factor of non-invasive ventilation requirement. results: patients requiring niv included 43.9 % of all studied patients. rsbi and apache ii score with sensitivity of 94.8 %, (cut off point = 110) and 72 % (cut off point = 14) respectively, had high diagnostic s...

results sixty patients were involved in this study. in asv mode, values including peak airway pressure (p-peak), end-tidal carbon dioxide (etco2), tidal volume and respiratory dead space were significantly lower than simv mode. although the mean value for dynamic compliance had no significant difference in the two types of ventilation, it was better in asv mode. methods in a crossover study, pa...

background: methanol is a colorless and poisonous liquid that is commonly used as an industrial and household solvent. methanol poisoning is a rare but extremely hazardous form of in toxication that affects the central nervous system and causes visual disorder, drowsiness, seizures and coma.  case presentation: a 29-years-old man with methanol intoxication presented with drowsiness and acidosis...

OBJECTIVE To compare intermittent mandatory ventilation (IMV) with synchronized intermittent mandatory ventilation plus pressure support (SIMV+PS) in terms of time on mechanical ventilation, duration of weaning and length of stay in a pediatric intensive care unit (PICU). METHODS This was a randomized clinical trial that enrolled children aged 28 days to 4 years who were admitted to a PICU be...

The mode of ventilation used during awake extubation has not previously been studied. We conducted a randomised controlled trial comparing spontaneous respiration, intermittent positive pressure ventilation, and pressure support ventilation (each n = 13) for incidence and severity of peri-extubation complications following routine elective surgery. We found the severity of peri-extubation cough...

This study aimed to verify habitual smoking effects on cardiopulmonary function in taekwondo athletes. Subjects were university taekwondo athletes aged 20-24 years in nonsmoker (n= 9) and smoker (n= 6) groups. Subjects underwent an exercise examination for their ventilation threshold, minute ventilation, oxygen uptake, maximum volume of minute oxygen consumption, heart rate, and oxygen pulse du...

the effect of chair position on respiratory parameters in patients undergoing mechanical ventilation     fallahinia ghh [1] ,baghcheghi n [2] ,oshvandi kh [3] *,taher a [4] , soltanian ar [5]     received: 7 feb, 2013 accepted: 15 may, 2013    abstract  background & aims : there are many barriers to the movement of patients requiring mechanical ventilation and these patients are at risk for com...

We describe difficult weaning after prolonged mechanical ventilation in three tracheostomized children affected by respiratory virus infection. Although the spontaneous breathing trials were successful, the patients failed all extubations. Therefore a tracheostomy was performed and the weaning plan was begun. The strategy for weaning was the decrease of ventilation support combining pressure co...
