BACKGROUND Prolonged mechanical ventilation, longer hospital stay, and a lower rate of home discharge have been reported with patient-ventilator asynchrony in medical patients. Though commonly encountered, asynchrony is poorly defined within the traumatically injured population. METHODS Mechanically ventilated trauma patients at an urban, level-1 center were enrolled. Breath waveforms were re...

BACKGROUND Airway suctioning in mechanically ventilated patients is required to maintain airway patency. Closed suction catheters (CSCs) minimize lung volume loss during suctioning but require cleaning post-suction. Despite their widespread use, there is no published evidence examining lung volumes during CSC cleaning. The study objectives were to quantify lung volume changes during CSC cleanin...

BACKGROUND Inhalation of hyperbaric oxygen (HBO) has been reported to decrease arterial oxygen tension (PaO(2)) in the early period after exposure. The current investigation aimed at evaluating whether and to what extent arterial blood gases were affected in mechanically ventilated intensive care patients within 6 h after HBO treatment. METHODS Arterial blood gases were measured in 11 ventila...

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...

OBJECTIVE To evaluate clinical effects of airway pressure release ventilation (APRV) in patients suffering from moderate to severe acute respiratory distress syndrome (ARDS).e of a patient presented with significant high aminotransferase levels due to the first human R. aeschlimannii infection ever detected in Italy. The hypothesis of rickettsiosis was made on the basis of a comprehensive medic...

BACKGROUND The discontinuation of mechanical ventilation after coronary surgery may prolong and significantly increase the load on intensive care unit personnel. We hypothesized that automated mode using INTELLiVENT-ASV can decrease duration of postoperative mechanical ventilation, reduce workload on medical staff, and provide safe ventilation after off-pump coronary artery bypass grafting (OPC...

INTRODUCTION We hypothesized the expiratory time constant (ƬE) may be used to provide real time determinations of inspiratory plateau pressure (Pplt), respiratory system compliance (Crs), and total resistance (respiratory system resistance plus series resistance of endotracheal tube) (Rtot) of patients with respiratory failure using various modes of ventilatory support. METHODS Adults (n = 92...

Knowledge of the fate and behaviour of the respiratory muscles during ventilatory support is important for the guidance of clinical care. Full support facilitates muscle metabolic repletion, but exposes them to the risk of disuse atrophy. The effect of partial support varies according to the selected mode: assisted mechanical ventilation (AMV) and synchronized intermittent mechanical ventilatio...
