There is conflicting evidence on harm related to exposure to supra-physiologic arterial oxygen tensions (hyperoxemia) in critically ill patients.

Increased resting heart rate as well as increased arterial stiffness are both independent predictors of cardiovascular events and mortality. Results of previous studies have failed to converge concern...
OBJECTIVEThe aim of this study was to examine the relationship between early arterial oxygenation thresholds and long-term outcome after severe traumatic brain injury (TBI).METHODSIn a post hoc analys...
Arterial stiffness has shown independent predictive value for all-cause and cardiovascular mortalities, as well as fatal and nonfatal coronary events. Physical activity (PA) is associated with reduced...
Photoplethysmography performed on the peripheral extremities or the earlobes cannot always provide sufficiently rapid and accurate calculation of arterial oxygen saturation. The purpose of this study ...
Arterial hypoxaemia is common in anaesthetised horses, but little information exists regarding restoration of arterial oxygen tension (PaO ) during recovery from anaesthesia, or if intra-operative man...
Hypoxemia is a frequent situation in clinical practice, particularly in intensive care units or perioperative. The mortality and morbidity increase for cardiovascular reason, due to hypoxi...
1. to evaluate diagnostic accuracy and performance of IVUS-derived quantitative parameters to predict functional significance of stenosis defined using all the available physiolo...
Peripheral arterial disease (PAD) is a common clinical manifestation of the systemic atherosclerotic process, and the ankle brachial index (ABI) is an ideal tool to diagnose PAD. The assoc...
The purpose of this study is to determine whether breathing high levels of oxygen during surgery affects oxygen levels after surgery. The second purpose of this study is to determine wheth...
Patients undergoing Open Cardiac Surgery will be randomized into two groups. Group I will be ventilated with 40% Fio2 during induction, surgery and in Postoperative care unit. Group II wil...
A respiratory stimulant that enhances respiration by acting as an agonist of peripheral chemoreceptors located on the carotid bodies. The drug increases arterial oxygen tension while decreasing arterial carbon dioxide tension in patients with chronic obstructive pulmonary disease. It may also prove useful in the treatment of nocturnal oxygen desaturation without impairing the quality of sleep.
Transient reduction in blood pressure levels immediately after exercises that lasts 2-12 hours. The reduction varies but is typically 5-20 mm Hg when compared to pre-exercise levels. It exists both in normotensive and hypertensive individuals and may play a role in excercise related PHYSIOLOGIC ADAPTATION.
Thickening and loss of elasticity of the walls of medium and large muscular ARTERIES with lesions in the innermost layer of the artery (ARTERIAL INTIMA). This disease process of atherogenesis includes the retention of cholesterol-rich LIPOPROTEINS and their binding to PROTEOGLYCANS in the arterial intima, generation of proinflammatory molecules that recruit MACROPHAGES to the subendothelial space, formation of FOAM CELLS, and eventual calcification of the arterial wall. These arterial plaques (atheromas) contain CARBOHYDRATES; BLOOD; and CALCIUM.
Sub-optimal OXYGEN levels in the ambient air of living organisms.
Process by which organic tissue becomes hardened by the physiologic deposit of calcium salts.
