The study hypothesis is that in critically ill patients there is significant differences between electrolyte levels measured using blood gas analysers and by laboratory techniques, and between levels measured on arterial and venous blood samples.
The sudy hypothesis is that in critically ill patients there is a significant difference between electrolyte levels measured using blood gas analysers and by laboratory techniques, and between levels measured on arterial and venous blood samples.
The study aim is determine the agreement between electrolyte levels measure by formal laboratory serum analysis and point-of-care blood gas analysis.
Also, to determine the agreement between electrolyte levels measured on simultaneous arterial and venous blood samples, using both serum and whole blood samples.

Critically ill patients need intravenous fluid therapy in order to correct or prevent problems with their fluid and/or electrolyte status and for renal protection. The decision for the opt...
This investigational study will investigate two different volume replacement regimes in patients suffering from compromised renal function.
Our objective is to determine if urinary electrolyte abnormalities exist in only one or both kidneys in patients with and without a history of kidney stones. To meet this objective, we are...
an observational cross-sectional study is done to calculate the electrolyte imbalance at different stages of chronic kidney disease at tertiary care hospital.
The aim of the study is to investigate the safety of a 6% Hydroxyethylstarch (HES) solution (Volulyte 6%) versus an electrolyte solution (Ionolyte) in trauma patients.
Serum electrolyte derangements are common in patients with decompensated cirrhosis hospitalized for hepatic encephalopathy. There are limited data describing the association between electrolyte levels...
A new ReaxFF reactive force field has been developed for water-electrolyte systems including cations Li+, Na+, K+ and Cs+, and anions F-, Cl- and I-. The reactive force field parameters have been trai...
The recognition of solid electrolyte interface (SEI) between the electrode materials and electrolyte is limiting the selection of electrode materials, electrolytes and further the electrochemical perf...
An electrolyte using 2,3,4,5,6-pentafluorophenyl methanesulfonate (PFPMS) as a versatile additive is investigated through calculating the molecular orbital energies of additives and solvents and desig...
We report the influence of electrolyte on the electrical contact between graphene nanoplates (GNPs) and an electrode via a single entity electrochemical technique. The current 'steps' were observed in...
The complete summaries of the frequencies of the values or categories of a measurement made on a group of items, a population, or other collection of data. The distribution tells either how many or what proportion of the group was found to have each value (or each range of values) out of all the possible values that the quantitative measure can have.
Disturbances in the body's WATER-ELECTROLYTE BALANCE.
A statistical analytic technique used with discrete dependent variables, concerned with separating sets of observed values and allocating new values. It is sometimes used instead of regression analysis.
A principle of estimation in which the estimates of a set of parameters in a statistical model are those quantities minimizing the sum of squared differences between the observed values of a dependent variable and the values predicted by the model.
Beliefs and values shared by all members of the organization. These shared values are reflected in the day to day operations of the organization.
