OBJECTIVES To understand the role of patient-ventilator asynchrony in the etiology of sleep disruption and determine whether optimizing patient-ventilator interactions by using proportional assist ventilation improves sleep. DESIGN Randomized crossover clinical trial. SETTING A tertiary university medical-surgical intensive care unit. PATIENTS Thirteen patients during weaning from mechani...
OBJECTIVE Noninvasive ventilation has been successfully used after thoracic surgery. However, noninvasive ventilation fails in about 20% of patients. The aim of the study was to analyze episodes of noninvasive ventilation failure and to assess possible risk factors, while taking into account the performance of fiberoptic bronchoscopy for secretion management. METHODS From January 2006 to June...
To determine the costs of pulmonary ventilation without imposing severe oxygen limitations or acidosis that normally accompany exposures to hypoxia or hypercapnia, we opted to pharmacologically stimulate ventilation with doxapram (5 and 10 mg kg(-1)) in alligators. Doxapram is used clinically to alleviate ventilatory depression in response to anaesthesia and acts primarily on the peripheral oxy...
Background: Neonatal respiratory distress syndrome (NRDS), a life-threatening pulmonary disorder, involves 1% of all deliveries worldwide. Shallow breathing causes restlessness in infants, which itself affects pulmonary function; thus, sedative medications are used to preserve better pulmonary function. There are different opinions about the benefits and superiority of these dr...
Background and Objectives: Increasing the concentration of carbon dioxide (CO2) leads to reduced comfort and learning disruption. Therefore, the present study was conducted to determine the concentration of CO2 in classrooms of Babol and Gonabad cities and its relationship with classroom ventilation and temperature. Materials and Methods: This descriptive study was randomly carried out in spr...

BACKGROUND In newborn resuscitation the recommended rate of chest compressions should be 90 per minute and 30 ventilations should be delivered each minute, aiming at achieving a total of 120 events per minute. However, this recommendation is based on physiological plausibility and consensus rather than scientific evidence. With focus on minute ventilation (Mv), we aimed to compare today's stand...
