Background: Pulse Oximeter monitoring has become so common over previous decades that in some health care units, blood oxygen level is now considered as the fifth vital sign. However, it seems there is still some lack of knowledge and/or experience among medical staff operating pulse oximeter and interpreting its results. The aim of this study was to investigate and compare the knowledge on Pul...

2014 The low temperature transient response of the polarization of a paramagnet to a fast high intensity (1 ms; 250 kG; 1/2 sine-wave) field pulse is shown to give information on spinlattice coupling, density and relaxation of phonon modes and, sometimes, magnetic ordering temperatures. LE JOURNAL DE PHYSIQUE TOME 35, DÉCEMBRE 1974, Classification Physics Abstracts 8.630 An analysis of the resp...

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...

medical environments such as hospital waiting rooms can affect a client’s anxiety level as wellas psychological and physiological responses to his or her situation. the aim of this research was to evaluatethe use of environmental design, specifically the design which incorporates elements of nature, in clinics andhospitals to decrease anxiety, blood pressure and pulse rates of waiting clients. ...

the in-situ method of synthesis has been used to isolate oxovanadium(iv) complexes with ligands derived by reaction of benzil with amino acids such as glycine, alanine, serine, cysteine and valine, where template effect of vo +2 cation appears to play an important role. the complexes are characterised by elemental analysis, magnetic moment measurements and spectral (infrared, electronic and ele...

The cytoplasmic side of the voltage-dependent Na+ channel pore is putatively formed by the S6 segments of domains I to IV. The role of amino acid residues of I-S6 and II-S6 in channel gating and local anesthetic (LA) block was investigated using the cysteine scanning mutagenesis of the rat skeletal muscle Na+ channel (Nav1.4). G428C uniquely reduced sensitivity to rested state or first-pulse bl...

The relevance of cortical grey matter pathology in multiple sclerosis has become increasingly recognized over the past decade. Unfortunately, a large part of cortical lesions remain undetected on magnetic resonance imaging using standard field strength. In vivo studies have shown improved detection by using higher magnetic field strengths up to 7 T. So far, a systematic histopathological verifi...

in this work, the influence of different edm parameters (pulse current, pulse voltage, pulse on-time , pulse off-time) in finishing stage on  the surface roughness (r a )  as a result of application copper electrode to a workpiece( cold work steel  din1.2379)  has been investigated. design of the experiment was chosen as full factorial. statistical analysis has been done and artificial neural n...

Acute systemic stress disrupts reproductive function by inhibiting pulsatile gonadotropin secretion. The underlying mechanism involves stress-induced suppression of the GnRH pulse generator, the functional unit of which is considered to be the hypothalamic arcuate nucleus kisspeptin/neurokinin B/dynorphin A neurons. Agonists of the neurokinin B (NKB) receptor (NK3R) have been shown to suppress ...
