Perfusion

whether the patient has an unstable heart condition, cannot hold his breath, or is obese, very tall, poly-traumatized, or a moving child. Its unmatched innovations include a 78 cm gantry bore, 307 kg capacity, 2 x 100 kW, 2 m scan range, whole-organ perfusion coverage, and 75 ms temporal resolution. Pediatric chest & body CT. Without sedation. The SOMATOM Definition Flash scan speed resulted in a scan time of a fraction of a second for the whole chest and body, and we could show that there is…

assist device that that will benefit patients with a life-threating illness such as cardiogenic shock, cardiac defects, and unstable angina (Darovic, 2002). The IABP will reduce the resistance to the left ventricular ejection and improve coronary perfusion as well as systemic blood flow (Darovic, 2002). During diastole, the balloon inflates to increase diastolic pressure higher than systole pressure while displacing blood volume equivalent to its inflation volume (Darovic, 2002). IABP will…

Respiratory failure is a deterioration of the gas exchange function of the lungs (Hinkle & Cheever, 2014). The lungs are not able to provide adequate oxygenation or ventilation for the blood. Respiratory failure is caused by impaired ventilation or perfusion mechanism in the lungs. Colon Cancer Colon cancer arises from the epithelial lining of the intestine. It may start as a benign polyp and become malignant. “It will invade and destroy normal tissue and extend into surrounding structures”…

Introduction Perfusion is a very important aspect to the human body. Perfusion is defined as the flow of blood through arteries and capillaries that deliver oxygen and nutrients to the cells and removing cellular waste from the body (Giddens, 2013, p. 148). For us to maintain optimal perfusion, we need are heart to generate sufficient cardiac output. This means transporting the blood through patent blood vessels to supply the tissues throughout the body. Impaired perfusion may occur when the…

disequilibrium state. The common cause of TBIs is vehicular accidents. Subsequent to Oliver’s neurological surgery, invasive measures are to be applied in monitoring intracranial pressure (ICP). An elevated ICP causes a critical reduction in cerebral perfusion pressure (CPP) and cerebral blood flow (CBF), which can lead to secondary ischaemic cerebral injury. Intracranial hypertension should not be prolonged, a number of studies show that an increase in ICP is strongly…

Gas exchange affects all processes of the body because everything in the body requires the gas exchange process to occur. The following are the interrelated concepts with gas exchange according to Giddens (2017); acid-base balance, anxiety, perfusion, nutrition, mobility, and fatigue. Acid-Base Balance is affected in a variety of different ways by gas exchange. For example, with chronic respiratory conditions such as COPD it causes respiratory acidosis which is essentially an increase in…

These medications also help increase stroke volume and contractility, which helps to improve tissue perfusion (Warise, 2015). Positive inotropic agents are also used in cardiogenic shock to maintain organ perfusion, as well as help improve the heart’s contractility (Warise, 2015). Beta blockers, such as metoprolol, are used to decrease the response of the sympathetic nervous system, reduce the heart rate…

1 Introduction Berberine (BBR), an isoquinoline alkaloid (Fig. 1), is isolated from many medicinal herbs, such as Coptidis rhizome (Coptis chinensis Franch.) and Cortex phellodendri (Phellodendron chinense C.K.Schneid.) (1). BBR has been used to treat microbial infection, diarrhea, and other gastrointestinal (GI) diseases due to its antibacterial, antidiarrheal and strong antidotal properties (2, 3). In recent years, much focus has been put on its other potential bioactivities, such as…

The inherent mechanical obstruction in the blood output from the ventricles creates enormous impacts on tissues. Evidently, the areas of hypo-perfusion will have less oxygen for aerobic activities, therefore, diverting to anaerobic processes that produces carbon dioxide and lactic acids. In this situation, the cells will have increase inflammatory coupled with clotting and if shock is irreversible…

occur as circulating chemical mediators released by the inflammatory response compromised the patients cardiovascular system (Cunha, 2003:24). Severe sepsis occurs when hypoperfusion, hypotension and organ dysfunction develop. If hypotension and perfusion abnormalities, lactic acidosis, oligoria and acute onset of mental deterioration occur despite aggressive fluid resuscitation and inotropic therapy, septic shock is present (Munford,…
