BACKGROUND Point of care (POC) glucose meters are routinely used to monitor glucose levels for patients on tight glycemic control therapy. We determined if glucose values were different for a POC glucose meter as compared to the main clinical laboratory for medical intensive care unit patients on a tight glycemic protocol and whether the site of blood sampling had a significant impact on glucos...

background: long surgery causes hypothermia and increased bleeding and can increase the arterial blood lactate levels during anesthesia. it causes cellular hypoxia and its complications. considering the core temperature of the patient during surgery it can prevent hypoxia. this study aimed to compare the effects of different temperatures on the core temperature and the concentrations of lactate...

abstract background: after coronary artery bypass surgery, pulmonary complications and oxygenation disorders are common, which have an important role in mortality and morbidity. different methods are used for the improvement of pulmonary function and oxygenation, of which incentive spirometry (is) has been investigated here. the aim of this study is to evaluate the effects of is on arterial blo...

introduction: controlling and reducing serum uric acid levels may have beneficial effects on blood pressure control. the current study was carried out to assess the effects of allopurinol administration on serum uric acid and arterial blood pressure among the patients under hemodialysis.  methods: this double-blind clinical trial was conducted on 132 hemodialysis patients (two separate groups) ...

____________ _ Measurements of transcutaneous POz (tc POz), intraarterial P02(P;02) and P02 of blood samples taken from the sampling port of the oxygenator (PoOz) were compared with arterial blood P02 (PaOz) in 16 adult patients undergoing cardiopulmonary bypass. tcP02 and Pi02 were recorded continuously using Roche-Kontron electrodes. Po02 and PaOz were measured intermittently on a Radiometer ...

Introduction: Management of critically ill patients involves extensive diagnostic testing and procedures to inform clinical decision making. This is commonly facilitated by an arterial catheter (AC) connected a pressurised administration set that maintains patency facilitates continuous monitoring. Blood sampling also enabled via this system but can result in blood wastage contamination.

background: patients undergone mechanical ventilation need rapid and reliable evaluation of their respiratory status. monitoring of end-tidal carbon dioxide (etco2) as a surrogate, noninvasive measurement of arterial carbon dioxide (paco2) is one of the methods used for this purpose in intubated patients. objectives: the aim of the present trial was to study the relationship between end-tidal c...

the purpose of this study was to investigate the potential responses of the cardiovascular system and regional blood flow to hypoxic hypoxia (bb) and to carbon monoxide (co)-induced hypoxia (coh). ten anesthetized cats were studied under two nonnoxic (control: cont) and two hypoxic conditions. four types of radioactive micro spheres were used to measure regional blood flow during cont and two h...
