Gain saturation effects of a flowing chemical oxygen-iodine laser

, 2004
A new oxygen-iodine medium gain model is developed to include pumping and deactivation of the upper laser levels of the iodine atoms, hyperfine and translation relaxation, as well as the flowing effect. The rate equations for gain of a supersonic flowing

Association between oxygen saturation level during bronchoscopy and post-bronchoscopy adverse events: a retrospective cohort study

Respiratory Research, 2022
Background Flexible bronchoscopy is widely used to diagnose and treat various respiratory diseases. However, caution is warranted for post-bronchoscopy adverse events.

Correlation between Oxygen Saturation and Hemoglobin and Hematokrit Levels in Tetralogy of Fallot Patients

Althea Medical Journal, 2016
Background: Hemoglobin and hematocrit levels increase in Tetralogy of Fallot (TOF) but the oxygen saturation declines. Reduced hemoglobin in circulating blood as a parameter of cyanosis does not indicate rising hemoglobin due to the ‘not-working ...

Predictive role of central venous oxygen saturation in patients with acute type i respiratory failure

Egyptian Journal of Chest Disease and Tuberculosis, 2020
Background Global oxygenation can be indirectly measured by the measurement of venous oxygen saturation. Objective To estimate the value of central venous oxygen saturation (ScvO2) to predict the outcome in type 1 acute respiratory failure (ARF) patients

Oxygen Saturation During Hemodialysis

Renal Failure, 1993
The aim of this study was to examine the saturation patterns of cuprofane and polysulfone membranes in hemodialysis patients, and to correlate that with permeability of the alveolar membrane, unloading of CO2 over the membranes, and production of oxygen free radicals.

Oxygen Saturation and Outcomes in Preterm Infants [PDF]

New England Journal of Medicine, 2013
The clinically appropriate range for oxygen saturation in preterm infants is unknown. Previous studies have shown that infants had reduced rates of retinopathy of prematurity when lower targets of oxygen saturation were used.In three international randomized, controlled trials, we evaluated the effects of targeting an oxygen saturation of 85 to 89%, as

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Femoral venous oxygen saturation is no surrogate for central venous oxygen saturation [PDF]

Critical Care, 2011
Objective: The purpose of our study was to determine if central venous oxygen saturation and femoral venous oxygen saturation can be used interchangeably during surgery and in critically ill patients. Design: Prospective observational controlled study. Setting: Nonacademic university-affiliated teaching hospital in The Netherlands.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

The use of two novel techniques in the coagulopathic trauma patient in intensive care [PDF]

, 2009
Severe Trauma is a multisystem disorder with a high mortality in an often young population. It offers a big challenge to the intensivist, and any help that is available might prove decisive in saving the patient’s life.
