Postoperative Hypoxemia and Oxygen Need in Bakers Compared with Cigarette and Water Pipe Smokers
Background: Hypoxemia is a frequent complication after general anesthesia. It usually takes longer to recover in individuals with respiratory problems. Bakers may suffer from respiratory problems such as asthma. The objective of this study was to compare the occurrence of hypoxemia and duration of supplemental oxygen administration during recovery from general anesthesia in bakers and smokers. ...
متن کاملCOPD and cognitive impairment: the role of hypoxemia and oxygen therapy
BACKGROUND several studies have shown an association between chronic obstructive pulmonary disease (COPD) and cognitive impairment. These studies have been limited by methodological issues such as diagnostic uncertainty, cross-sectional design, small sample size, or lack of appropriate referent group. This study aimed to elucidate the association between COPD and the risk of cognitive impairmen...
متن کاملNocturnal hypoxemia and long-term domiciliary oxygen therapy in "blue and bloated" bronchitics. Physiopathologic correlations.
T he original reports of Neff and Petty’ that long-term domiciliary oxygen therapy could extend the life of patients with chronic bronchitis and emphysema were made in patients living at altitude in Denver. Although later studies have suggested that similar benefits can be obtained from patients living at sea level, this is yet to be confirmed by a formal controlled trial. The economic importan...
متن کاملWhich patients with moderate hypoxemia benefit from long-term oxygen therapy? Ways forward
Long-term oxygen therapy (LTOT) improves prognosis in patients with COPD and chronic severe hypoxemia. The efficacy in moderate hypoxemia (tension of arterial oxygen; on air, 7.4-8.0 kPa) was questioned by a recent large trial. We reviewed the evidence to date (five randomized trials; 1,191 participants, all with COPD). Based on the current evidence, the survival time may be improved in patient...
متن کاملHypoxemia, oxygen content, and the regulation of cerebral blood flow.
This review highlights the influence of oxygen (O2) availability on cerebral blood flow (CBF). Evidence for reductions in O2 content (CaO2 ) rather than arterial O2 tension (PaO2 ) as the chief regulator of cerebral vasodilation, with deoxyhemoglobin as the primary O2 sensor and upstream response effector, is discussed. We review in vitro and in vivo data to summarize the molecular mechanisms u...
