We found no difference between iFLO and iVEL when comparing the change in the PaO2/FiO2 ratio, safety, and cost in hypoxic, critically ill patients. There were differences in secondary outcomes, likely a result of differences in underlying indication for inhaled epoprostenol.
Purpose-Noninvasive positive pressure ventilation (NPPV) can improve outcomes of critically ill patients. Early and simple predictors of NPPV outcome could improve clinical management of patients with respiratory failure.Materials and Methods-A prospective observational study was conducted in a medical intensive care unit (ICU) of a tertiary medical center. Patients requiring NPPV were included and followed. Clinical data including respiratory mechanics at the time of NPPV initiation, and clinical outcomes were recorded. Data were analyzed to identify variables that distinguished NPPV success or failure.Results-A total of 133 patients were included in the study. NPPV success rate was 41%. Patients diagnosed with malignancy had only 29% NPPV success rate. Among patients without malignancy, higher oxygen saturation, oxygen saturation/FiO 2 (SF) ratios, and SF/minute ventilation (MV) ratios were associated with NPPV success. Receiver operating curve analyses identify SF < 98.5 to be a specific (89% specificity, P=0.013) predictor of NPPV failure. Furthermore, for patients requiring at least 24hr of NPPV support, tidal volume (TV)/predicted body weight (PBW) ratio inversely correlated with respiratory improvement.Conclusions-For patients without malignancy, SF ratios at the time of NPPV initiation discriminated NPPV success and failure, and could be used to help guide the management of critically ill patients who require ventilatory support.
Current clinical guidelines recommend capnography as one of the best non-invasive methods to assess adequacy of ventilation in the non-intubated patient. Alveolar hypoventilation or respiratory depression is a serious event that occurs in a variety of clinical settings where patients receive sedatives and opioids. With the large number of procedures performed outside the operating room under the effects of sedatives and the increased use of patient-controlled analgesia, the need for capnography for monitoring has dramatically increased. Despite the succesful use of capnography to monitor ventilation in the operating room over several decades, other clinical areas have been very slow adapters of the technology and still rely heavily upon pulse oximetry to detect hypoventilation. This article reviews the most current evidence for using capnography in the non-intubated patient and summarizes the results of outcome measures reported in recent clinical trials. Capnography should be routinely used for non-intubated patients at risk for respiratory depression, in particular those receiving supplemental oxygen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
