STUDY OBJECTIVE We conduct a systematic review and meta-analysis to evaluate the effectiveness of apneic oxygenation during emergency intubation. METHODS We searched Ovid MEDLINE, Ovid EMBASE, Ovid CENTRAL, and Scopus databases for randomized controlled trials and observational studies from 2006 until July 2016, without language restrictions. Gray literature, clinicaltrials.gov, and reference...
Previous reports indicate roles for acid-sensing ion channels (ASICs) in both peripheral and central chemoreception, but the contributions of ASICs to ventilatory drive in conscious, unrestrained animals remain largely unknown. We tested the hypotheses that ASICs contribute to hypoxic- and hypercapnic-ventilatory responses. Blood samples taken from conscious, unrestrained mice chronically instr...
Postoperative hypoxemia can be a challenging diagnostic and management dilemma for the clinician. We present here a case of postoperative hypoxemia following laparoscopic gastric bypass surgery secondary to presumed pulmonary embolism complicated with a patent foramen ovale. The diagnostic pitfalls associated with a negative spiral computed tomography scan and the impact of coexisting medical c...

OBJECTIVE To describe the response to exercise of normal subjects and patients with chronic obstructive pulmonary disease (COPD) in Bogota, Colombia (altitude: 2640 m; atmospheric pressure: 560 mm Hg) and compare it with data published on COPD patients at sea level. Healthy people increase their minute ventilation to attenuate hypoxemia (PaCO2: 30 mm Hg; PaO2: 63 mm Hg). MATERIAL AND METHOD A...
ARDS is characterized by hypoxemic respiratory failure, which can be refractory and life-threatening. Modifications to traditional mechanical ventilation and nontraditional modes of ventilation are discussed in Part 1 of this two-part series. In this second article, we examine nonventilatory strategies that can influence oxygenation, with particular emphasis on their role in rescue from severe ...
BACKGROUND Acute lung injury following trauma resuscitation remains a concern despite recent advances. With the use of the PROMMTT study population, the risk of hypoxemia and potential modifiable risk factors are studied. METHODS Patients with survival for 24 hours or greater with at least one intensive care unit day were included in the analysis. Hypoxemia was categorized using the Berlin de...
Hypoxemia during hemodialysis may result from several differing processes. We initially studied patients undergoing standard acetate hemodialysis. At 15 minutes of dialysis, leukopenia (primarily neutropenia), a decline of platelet count, and hypoxemia occurred, but without a significant change in mean minute ventilation. Complement activation (V/A ratios of C5a greater than 1.0) persisted thro...
acute respiratory distress syndrome (ards) is a potential complication of cardiac surgery, given that patients undergoing cabg frequently have hypoxemia and pulmonary dysfunction during initial hours after surgery. thus, ards criteria in these patients are more likely to be positive while these criteria may not match the patient`s clinical picture. we aimed to investigate frequency of rapid ons...
