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...

Research shows that misconceptions about human blood circulation and gas exchange persist across grade levels. The purpose of this study was twofold: 1) to investigate the prevalence and persistence of blood circulation misconceptions among prospective elementary teachers and 2) to evaluate the effectiveness of learning activities for discovering what students know and can explain about blood c...

INTRODUCTION Glucose control to prevent both hyperglycemia and hypoglycemia is important in an intensive care unit. Arterial blood gas analyzers and glucose meters are commonly used to measure blood-glucose concentration in an intensive care unit; however, their accuracies are still unclear. METHODS We performed a systematic literature search (January 1, 2001, to August 31, 2012) to find clin...

The use of continuous in-line blood gas management (CILBGM) is steeped in controversy concerning its potential utility and impact on patient outcomes. The purpose of this study was to determine whether the use of CILBGM results in improved quality of patient care. Fifty-nine patients were enrolled in a Institutional Review Board-approved, prospective, randomized study. An in-line blood gas moni...

background: one of the main problems especially in operating room and monitoring devices is measurement of blood pressure (bp) by sphygmomanometer cuff. objective: in this study we designed a new method to measure bp changes continuously for detecting information between cuff inflation times by using vital signals in monitoring devices. this will be achieved by extraction of the time difference...

A fluorescence-based fiber optic measurement system has been developed for monitoring pH, pCO2, and pO2 through a 20-gauge radial artery catheter without compromising capabilities for monitoring arterial pressure or for blood withdrawal. The measuring probe consists of three optical fibers to which the sensing chemistries are attached, and a thermocouple that measures temperature. The probe is ...

BACKGROUND Ventilation monitoring practice for intubated pediatric patients with severe traumatic brain injury (TBI) during interfacility transport (IFT) has not been well documented. We describe the difference of practices in ventilation monitoring during IFT from the perspective of a level I pediatric trauma center with an enormous catchment area. METHODS Patients admitted between July 2008...

Accurate and timely glucose monitoring is essential in intensive care units. Real-time continuous glucose monitoring system (CGMS) has been advocated for many years to improve glycemic management in critically ill patients. In order to determine the effect of calibration time on the accuracy of CGMS, real-time subcutaneous CGMS was used in 18 critically ill patients. CGMS sensor was calibrated ...

OBJECTIVE To reveal the significance of continuous transcutaneous carbon dioxide (CO(2)) level monitoring through reviewing cases which showed a discrepancy in CO(2) levels between arterial blood gas analysis (ABGA) and continuous transcutaneous blood gas monitoring. METHOD Medical record review was conducted retrospectively of patients with neuromuscular diseases who had started home mechani...

introduction blood pressure (bp) is one of the important vital signs that need to be monitored for personal healthcare. arterial blood pressure is estimated from pulse transit time (ptt). this study uses two pulse sensors to get ptt. the aim of this study was to construct an optical system and to monitor blood pressure continuously and without cuff in people with different ages. materials and m...
