Pulmonary effects of repeated six-hour normoxic and hyperoxic dives

Normoxic and Hyperoxic Cardiopulmonary Bypass in Congenital Heart Disease

Cyanotic congenital heart disease comprises a diverse spectrum of anatomical pathologies. Common to all, however, is chronic hypoxia before these lesions are operated upon when cardiopulmonary bypass is initiated. A range of functional and structural adaptations take place in the chronically hypoxic heart, which, whilst protective in the hypoxic state, are deleterious when the availability of o...

Decompression sickness following repeated breath-hold dives.

Role of CO2 in the cerebral hyperemic response to incremental normoxic and hyperoxic exercise.

Cerebral blood flow (CBF) is temporally related to exercise-induced changes in partial pressure of end-tidal carbon dioxide (PetCO2 ); hyperoxia is known to enhance this relationship. We examined the hypothesis that preventing PetCO2 from rising (isocapnia) during submaximal exercise with and without hyperoxia [end-tidal Po2(PetO2 ) = 300 mmHg] would attenuate the increases in CBF. Additionally...

Controls should exist for hyperoxic and normoxic conditions in all experiments involving anesthetics.

Anesthesiology 2013; 118:460-71 464 Correspondence advantages and disadvantages. The “spray as you go” technique may be unnerving to the less trained anesthesiologist because it causes coughing and perhaps a subsequent loss of vision when spraying through the fiberscope. Therefore, topical anesthesia may be achieved with the fiberscope but intubation may fail! We chose the transtracheal local a...

the effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
