background: this study was conducted to assess the validity and reliability of ankle?brachial index (abi) by oscillometric blood pressure (bp) measurement as compared with an automated abi as a gold standard. materials and methods: this study was conducted at golden jubilee medical center, thailand. all the data were collected from 303 patients at risk of peripheral arterial disease (pad) who w...
At the present time, plastic syringes are most commonly used for collecting arterial blood. The oxygen tension of the arterial blood (Pa,O2) in these syringes may fall. We studied the effect of the type of syringe, metabolism, and storage time on the arterial oxygen pressures measured and on the pulmonary shunt calculated. In 10 patients, 2-3 h after aortacoronary bypass surgery, a 100% oxygen ...
Methods From July 2014 to January 2015,22 patients were enrolled.All the subjects underwent RTCGMS(San MediTech) for five days. Capilllary glucose values through self-monitoring of blood glucose(SMBG)were input twice a day for adjustment. Meanwhile, arterial cannula was placed for arterial blood sampling. The value of RTCGMS,SGMB and arterial blood glucose(ABG) at the same time were recorded ev...
Non-invasive measurements of regional cerebral blood flow (133Xe inhalation or IV injection) require knowledge of the arterial 133Xe concentrations, which is usually estimated from the end-tidal expiration. An automated sampling system is described for measurement of end-tidal 133Xe concentration that can be used in both spontaneously breathing and mechanically ventilated patients. A comparison...
Introduction : which is manifested by reduction in arterial blood oxygen. The present study was conducted to evaluate the frequency, clinical and para clinical features of HPS, and to determine their predictive values in diagnosis in a group of Iranian patients . Materials and methods : consecutively to the gastroenterology department of Taleghani Hospital between 2003 and 2004. Patients unde...
Description of a new non‐injectable connector to reduce the complications of arterial blood sampling
The objective was to compare blood flow to the hindquarters of steers measured by transit time ultrasound with blood flow determined by indicator (p-aminohippurate) dilution. Five Hereford steers had ultrasonic flow probes on the abdominal aorta and catheters in the abdominal aorta and inferior vena cava inserted through both sets of circumflex iliac vessels. Indicator was infused continuously ...
OBJECTIVE Our purpose was to evaluate the relationship between umbilical cord arterial blood lactate levels with acid base balance to the mode of delivery and short-term neonatal outcome in a large multiracial population delivering at term in University of Malaya Medical Centre. MATERIALS AND METHODS Two thousand two hundred and twelve patients of more than 37 weeks of gestation with singleto...
