BACKGROUND An increased volume of patients is associated with improved survival in numerous high-risk medical and surgical conditions. The relationship between the number of patients admitted (hospital volume) and outcome among patients with critical illnesses is unknown. METHODS We analyzed data from 20,241 nonsurgical patients receiving mechanical ventilation at 37 acute care hospitals in t...

The last very-successful management of mechanical ventilation was in 2000 when application of low tidal volume and moderate pressure was introduced. It was then followed by the open- and baby-lung concept in order to open up the lung and keep the lung open. However, these strategies are followed with several adverse effects. Therefore, studies were performed in order to improve the outcome of m...

background: endotracheal or tracheostomy tube in mechanically ventilated patients disturb verbal communication with others. therefore, patients are frustrated of requesting for their needs or problems related to artificial breathing. therefore investigating self-experiences of these patients can be applied in providing them with a better care by clinical personnel. methods: this is a qualitativ...

abstract: the new neonatal ventilation methods have been developed along with utilization of new technological tools.this device is synchronized with the patient’s respiratory efforts. the ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .the synchrony of respiration contribut...

RATIONALE Mechanical ventilation of severe acute asthma is still considered a challenging issue, mainly because of the gas trapping phenomenon with the potential for life-threatening barotraumatic pulmonary complications. PATIENT CONCERNS Herein, we describe 2 consecutive cases of near-fatal asthma for whom the recommended protective mechanical ventilation approach using low tidal volume of 6...

Introduction Electrical impedance tomography (EIT) is a non-invasive and portable lung imaging technique for dynamic evaluation of lung volume distribution. Previous studies had proved the EIT can provide information on regional distribution of ventilation and changes in end-expiratory lung volume (△EELV). The effect of EIT application in ventilation distribution of prolonged mechanical ventila...

During mechanical ventilation, phasic changes in systemic venous return modulate right ventricular output but may also affect left ventricular function by direct ventricular interaction. In 13 anesthetized, closed-chest, normal dogs, we measured inferior vena cava flow and left and right ventricular dimensions and output during mechanical ventilation, during an inspiratory hold, and (during apn...

In a recent issue of CHEST (June 2015), we read with interest the randomized controlled trial (RCT) by Kirakli et al comparing adaptive support ventilation (ASV) with pressure assist/control ventilation (P-ACV) for the entire duration of mechanical ventilation (MV) in a cohort of 229 patients in the medical ICU. The study showed a shorter duration of the weaning process and total MV in the ASV ...
