Positive airway pressure

motion of water molecules through a semi-permeable membrane due to difference in osmotic pressure driving force through the membrane. The membrane enables only water molecules to pass through when salt molecules are rejected. The forward desalination technique makes use of a draw solution with high osmotic pressure to draw the water molecules from a inlet solution such as brackish with lower osmotic pressure in contrast to the draw solution. As illustrated in Figure 1, water flux directions…

Recently I went in for my maintenance ECT, which is electroconvulsive therapy, also known as, shock therapy. I needed it. My mood has been shifting from my neutral to a depressive episode, which can be dangerous for me. I can call into my doctor and tell them I am struggling and they can get me in on either a Monday, Wednesday, or Friday. They got me in on that Friday. Because I have been doing ECT for about four years now, I have been able to start remembering the experience more and more each…

Arterial blood gas (ABG) and electrolytes analysis is an important test to monitor acid-base balance and the assessment of gas exchange. Various factors can affect the accuracy of the results. A study showed that; the ABG’s results changes occurs when the analysis is delayed. They suggested storing the blood on bag of ice to minimize changes. According to The American Association for Respiratory Care Clinical Practice Guideline the blood sample should be analyzed in 10-15 minutes at room…

Case Study 5 – AB As discussed in case 3, septic shock results from widespread inflammation and vasodilation in response to an infection. Norepinephrine is useful in septic shock because it increases afterload to maintain adequate tissue perfusion (De Becker et al., 2012). Dobutamine is an inotropic drug used in septic shock as it stimulates myocardial beta-adrenergic receptors thus increasing cardiac output by increasing contractility and heart rate (Dellinger et al., 2013; Enrico et al.,…

High Blood Pressure Gisselle Nogueira Essay 2 Final Version High blood pressure, scientifically known as hypertension is a very common disease in adults. This happens when blood flows through blood vessels at higher than normal pressures. There are different causes to this disease. Some include smoking, diet with a lot of sodium, and poor physical activity. Although it is hereditary, there are ways to prevent complications from hypertension like a heart attack, dementia, and…

checked your blood pressure? You should monitor your blood pressure often because it is vital to your health. High blood pressure is common in many people and is found in all different ages. “In the United States, approximately 85 million people have high blood pressure” (Nordqvist). High blood pressure is a serious medical condition with many causes that can lead to heart attack and stroke. So what is high blood pressure and what causes it? “If a person has high blood pressure it means the…

Blood enters the capillaries of the nephron through the afferent arteriole. It then flows through the glomerulus and into the efferent arteriole. The varying sizes of these arterioles help to create the hydrostatic pressure and to maintain consistency of glomerular capillary pressure and renal blood flow within the glomerulus Before returning to the renal vein, blood from the efferent arteriole enters the peritubular capillaries and the vasa recta and flows slowly through the cortex and…

Physiology of intracranial pressure (ICP) 1. Intracranial pressure dynamics: Intracranial pressure is the pressure of cerbrospinal fluid inside the skull.Normally the cranial vault is a closed box and non compliant structure containing volume of approximately 1500 ml ,comprissing 88% brain matter ,7.5% blood and 4-5 % cerebrospinal fluid . Monrroe kelle hypothesis concludes that any increase in the volume of an intracranial element must be met with an equal compensatory decrease in…

levels of intensity, Acute Mountain Sickness (AMS), High Altitude Cerebral Edema (HACE), and High Altitude Pulmonary Edema (HAPE). These illnesses occur when someone is exposed to levels of higher elevation, reduced oxygen levels and lowered air pressure. Altitude sickness causes the veins and capillaries to expand in order to take in more oxygen. Some scientists also believe that it can cause the brain to slightly swell. Altitude sickness can affect anyone over 6000 feet in elevation. It can…
