AIM To compare T-tube and pressure support ventilation (PSV) as two methods of mechanical ventilation weaning of patients with chronic obstructive pulmonary disease (COPD) after failed extubation. METHODS A prospective randomized trial carried out at the multidisciplinary intensive care unit (ICU) over 2 years included 136 patients with COPD who required mechanical ventilation longer than 24 ...

BACKGROUND We compared spontaneous and positive-pressure ventilation in patients undergoing general anaesthesia for the treatment of extrathoracic, intralumenal laryngotracheal stenosis to assess the best method of ventilation in this patient group. METHODS Records of 30 patients with laryngotracheal stenosis, but not with a tracheostomy, undergoing lumen-restoring surgery were prospectively ...

BACKGROUND Non-invasive ventilation can prevent respiratory failure after extubation in individuals at increased risk of this complication, and enhanced survival in patients with hypercapnia has been recorded. We aimed to assess prospectively the effectiveness of non-invasive ventilation after extubation in patients with hypercapnia and as rescue therapy when respiratory failure develops. MET...

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...

The Four Truths 1. truth of confusion 2. the origin 3. cessation 4. path leading to 10-Fold Path A breath is one cycle positive flow (inspiration) and negative (expiration) defined in terms flow-time curve. assisted if ventilator does work on patient. assists breathing using either pressure control or volume based equation motion for respiratory system. Breaths are classified by criteria that t...

Editor—Curtis and colleagues presented an interesting case in which a patient with anticipated difficult intubation was paralysed with rocuronium and developed a cannot intubate/cannot ventilate (CI/CV) situation. Sugammadex was administered, resulting in successful recovery of the patient’s motor strength, but ventilation was still impossible, presumably due to swelling of the airway and bleed...

Pressure controlled ventilation, and pressure support for spontaneous breathing are often used in intensive care because coordination of the ventilator with patient efforts can improve comfort and possibly reduce sedation. However we report a series of 10 patients whose efforts did not synchronise with pressure controlled ventilation. This was incorrectly diagnosed as inadequate sedation, and t...

Pulmonary arteriovenous malformation (PAVM) is an uncommon congenital anomaly. As PAVM is a direct communication between branches of the pulmonary artery and vein, major disturbances in gas exchange can result. We present a patient with an unsuspected PAVM who came to our institution for drainage of a brain abscess. Arterial blood gas analysis during and after surgery demonstrated a large alveo...

Partial ventilatory support modalities are ill defined and different perceptions about these modes might depend on geographic region. Exemplary on two recent publications investigating airway pressure release ventilation (APRV) in an adult ICU population, the question is investigated whether research in ventilation modes can be performed with the current definitions. The lack of precise definit...
