Sedative-hypnotic drugs as well as narcotics are commonly used perioperatively to make regional anesthesia more tolerable for patients by reducing anxiety and providing an appropriate degree of sedation, amnesia, and…
GCS = Glasgow coma scale; Hgb = hemoglobin; HR = heart rate. Adapted from MacIntyre NR, Cook DJ, Ely EW Jr, et al. Evidence-based guidelines for weaning and discontinuing ventilatory…
The physiology is as follows: when a patient is moved right and left through an arc, injurious cytokines are distributed diffusely throughout the lungs. The blood flow can shift around…
Returning to the case study mentioned at the beginning of this article, the patient presented initially received PPV and then was extubated to spontaneous ventilation. Thus, the patient’s already depressed…
Neuromuscular weakness from spinal cord injury, peripheral nerve disease processes such as Guillain-Barré syndrome, the neuromuscular junction like myasthenia gravis, or myopathy can be assessed with a negative inspiratory force…
PEEP, positive end-expiratory pressure; ARDS, acute respiratory distress syndrome; LIS, lung injury score; ALI, acute lung injury; PAOP, pulmonary artery occlusion pressure; LV, left ventricle. aSum scores from each domain…
See text for explanations of points a, b, c, and d. PAW = airway pressure; Pes = esophageal pressure. Another triggering problem can be caused by air trapping. When the…
See text for explanations of points a, b, c, and d. PAW = airway pressure; Pes = esophageal pressure. With the pressure breath, neither volume nor flow is being set….
