Pressure support is a ventilatory mode, available with many microprocessor ventilators, which is patient-triggered, pressure-limited, and flow-cycled. This study compared the respiratory and hemodynamic effects of PS used as a stand-alone mode of ventilation with those of conventional patient-triggered, flow-cycled, assisted mechanical ventilation. Instruments for hemodynamic and respiratory me...

Two interventions to overcome the deleterious impact irregular breathing has on thoracic-abdominal 4D computed tomography (4DCT) are (1) facilitating regular breathing using audiovisual biofeedback (AVB), and (2) prospective respiratory gating of the 4DCT scan based on the real-time respiratory motion. The purpose of this study was to compare the impact of AVB and gating on 4DCT imaging using t...

Background: Early nasal continuous positive airway pressure (NCPAP) has emerged as a primary modality of respiratory support for preterm infants withrespiratory distress syndrome (RDS). However, 30%-40% of these newborns need subsequent mechanical ventilation. Nasal intermittent positive pressure ventilation (NIPPV) is a promising alternative to NCPAP, especially in po...

background: determining the clinical significance of cardiac murmurs is widely considered in equine practice. pulmonary murmurs are commonly detected in athletic horses. echocardiography plays a leading role in assessment of these murmurs. objectives: echocardiographic evaluation of horses with pulmonary regurgitation and determining the importance of pulmonary valve murmurs. methods: a total n...

BACKGROUND Increased intra-abdominal pressure (IAP) results in dysfunction of vital organs. The aim of the present study was to evaluate the effect of mechanical ventilation mode on IAP. METHODS In a cohort study, a total of 60 patients aged 20-70 years who were admitted to the ICU and underwent mechanical ventilation were recruited. Mechanical ventilation included one of the three modes: Bip...

PROPORTIONAL assist ventilation (PAV) is a new mode of synchronized partial ventilatory support designed to optimize adaptation of the ventilator to the patient.1 Proportional assist ventilation differs markedly from other modes of partial assistance. Rather than providing a fixed volume or pressure assistance to the patient, PAV generates pressure assistance in proportion to the patient’s own ...

The increased morbidity and mortality resulting from respiratory failure in patients with neuromuscular disorders and/or kyphoscoliosis can be reversed with non-invasive ventilation. Spontaneous mode bilevel pressure ventilation is preferred to other modes of ventilation, due to relative ease of use, but may not be suitable for all patients. We report a 27-year old woman with Multi-minicore dis...

INSERM UMR1101, LaTIM, Brest, France Respiratory motion in PET/MR imaging leads to reduced quantitative and qualitative image accuracy. Correction methodologies include the use of respiratory synchronized gated frames which lead to low signal to noise ratio (SNR) given that each frame contains only part of the count available throughout an average PET acquisition. In this work, 4D MRI extracted...
