Sickle Cell Crisis
Under hypoxic conditions, the abnormal hemoglobin start to change shape. They become sickled, stiff, and have greater difficulty moving though the blood vessels. As a result they begin to stick together and eventually block the tissues from receiving nutrients and oxygen. This causes the tissue to become infarcted and leads to pain. In a hypoxic states the cells are forced to make energy also known as adenosine triphosphate (ATP) without oxygen. This is called anaerobic glycolysis and results in the production of lactic acid as a byproduct (citation). The presence of lactic acid lowers the pH of the environment, the cells must recycle lactic acid back into the cells, and ATP production is significantly slowed. The cells

Sammy is rating his pain as a 10 out of 10 on a scale where 10 is the highest level of pain and 1 is the lowest. It is evident that some of the choices Sammy made prior to ending up in the emergency room were not beneficial to his health. Sammy has been discarding lunches and drinks as school, is feeling nauseas, having diarrhea, and was playing in 21 degrees Fahrenheit weather without a jacket. Sammy’s diarrhea may be explained by his electrolyte imbalance as a high potassium (K+) level can cause diarrhea. Due to the fact that sickled RBCs are blocking blood flow, oxygen cannot be delivered to the cells. As the cells produce lactic acid, the pH is lowered creating an acidotic environment. With an increase in hydrogen (H+) ions, K+ moves out of the cell into extracellular fluid (ECF) to maintain ionic balance, explaining a K+ level of 6.2 mEq/L (citation). Sammy’s arterial blood gas (ABG) results also play a role in determining Sammy’s condition. With a low pH of 7.28, PCO2 of 32, a PO2 of 64, and a HCO3 21 these results are indicative of metabolic acidosis. Sammy’s increased respiratory rate of 32 breaths per minute is the body’s was of compensating for increased levels of acid. The body increases respirations in order to excrete CO2 at a higher rate and increase the pH level. Unfortunately, the body can only keep this up for so long as this type of buffering system is physically …show more content…
Dehydration increase the viscosity of the blood, creating an environment where the RBCs will have an increased tendency to stick together. As recommended by Brown (2012), intravenous (IV) fluids should be administered for rehydration with a close watch on electrolytes and kidney function to prevent under or over hydration. As the patient’s condition proves, the nurse should encourage an increased oral intake of fluids (Brown, 2012). Hydrating the patient will reduce the viscosity of the blood and prevent sickled RBCs from clumping and impeding proper circulation. Also, with improved circulation, tissue will receive adequate oxygen and nutrition, reversing tissue injury and reduce pain. Oxygen should also be administered to aide in increasing the amount of oxygen in circulations for individuals with an oxygen saturation below 95% (Reddin, Cerrentano, and Tanabe,
Also, hypoxia, which is a lack of oxygen, is another pathological physiological outcome of sepsis as less oxygen is reaching the tissue; this is due to the fact that there is less oxygen in the blood.
Hypovolemic shock specifically disrupts the cardiovascular system from a significant loss of blood volume that causes blood pressure to deplete and oxygen delivery to cells to slow. A victim entering into hypovolemic shock will experience three sequential stages as the body attempts to maintain homeostasis. These stages are named compensated, decompensated, and irreversible (Wang
Once the paramedics retrieve Marc, he will have a high concentration of salt in his blood and fluids. This means that the paramedics would treat him with the half normal saline. This is the solution with the lowest percentage of solutes (0.45% NaCl).this will increase his concentration of water throughout this body and will return his cells to their normal size. However, if the paramedics were to keep him on the half normal saline for too long, his water concentration would be too high and his solute concentration would become too low. This would mean that the paramedics would then need to switch Marc to the normal isotonic saline solution (0.9% NaCl). This would balance out both the concentration of water and solutes so that they are now equal. This would set his balance and homeostasis back to normal, thereby helping his recovery. (Johnson
In this activity Respiratory Responses to Metabolic Acidosis and Metabolic Alkalosis is recorded. As the metabolic rate increases, BPM increases, Blood pH decreases, carbon dioxide increases, hydrogen ion increases and bicarbonate level decreases. Likely as the metabolic rate decreases, BPM decreases, Blood pH increases, Pco2 decreases, Hydrogen ion decreases, and bicarbonate level decreases. The respiratory system compensates for metabolic

1. Sickle Cell Disease is life-threatening and has a risk of of causing depression. In this study I examine the experiences that Sickle Cell patients go through specifically at emergency healthcare facilities to find out if there are any negative stigmatizations surrounding this disease. There may be judgments that are made about these patients from healthcare professionals when they seek drugs for their pain relief that may cause the stigmatization to occur. I will also investigate why individuals that have Sickle Cell Disease experience longer waiting times at emergency healthcare facilities and the lack of control they may have over their care regime.
That is when muscles switch from aerobic respiration to lactic acid fermentation. Lactic acid fermentation is the process by which muscle cells deal with pyruvate during anaerobic respiration. Lactic acid fermentation is similar to glycolysis minus a specific step called the citric acid cycle. In lactic acid fermentation, the pyruvic acid from glycolysis is reduced to lactic acid by NADH, which is oxidized to NAD+. Lactic acid fermentation allows glycolysis to continue by ensuring that NADH is returned to its oxidized state (NAD+). When glycolysis is complete, two pyruvate molecules are left. Normally, those pyruvates would be changed and would enter the mitochondrion. Once in the mitochondrion, aerobic respiration would break them down further, releasing more
...epending on the patient’s dehydration, therefore also affecting the patient’s tonicity. The patient would also be losing water insensibly, in an unperceived way through their skin and lungs (Martini). This could be combative with the patient experiencing shortness of breath, in order to preserve some water from evaporating. In order to maintain proper osmolarity, the intercellular fluid would loose water to the extracellular fluid. This patient would need the replace the fluids he has lost by drinking water, or through intravenous isotonic crystalloid. I would suggest intravenous isotonic crystalloid since it would restore the body to homeostasis much quicker than through drinking. It is important that fluid balance, membrane transport, and overall homeostasis be maintained, for the longer the body is out of homeostatic range, the more detrimental the effects will be.
What is Sickle cell disease? Sickle cell affects a disease; that disease is called which affects the hemoglobin when the red blood cells that send oxygen through the body are killed off and weakened. Sickle cells can be found in every 1 and 1000 African Americans, it is affecting about 70,000 to 80,000 Americans in the United States. Sickle cell is a death threatening disease, and the severity of symptoms can vary from person to person (Sickle cell disease (SCD), 2015). Some people have light conditions, but others can have severe conditions, which, mean they could be hospitalized. Characteristics of this disease are caused by a minimum of low blood cells, which is called anemia.
Sickle cell anemia is a hereditary disorder that mostly affects people of African ancestry, but also occurs in other ethnic groups, including people who are of Mediterranean and Middle Eastern descent. More than 70,000 Americans have sickle cell anemia. And about 2 million Americans - and one in 12 African Americans - have sickle cell trait (this means they carry one gene for the disease, but do not have the disease itself).
Currently there are two types of renal replacement therapy. The original dialysis which we called it hemodialysis used for patients with chronic renal failure, needs the patients to come to hospital 2-3 times per week. This type of dialysis called the intermittent hemodialysis .However the intermittent hemodialysis is difficult to do it in the intensive care population with acute renal failure because of the hemodynamic instability and those type of patients usually are the most sick and critically ill patients within the intensive care units and have multiorgan dysfunctions, so medically is too difficult to do for them intermittent hemodialysis. In addition intermittent hemodialysis will increase the mortality and morbidity among them. Within the modern intensive care units new way of dialysis has been developed 30 years ago called continuous renal replacement therapy (CRRT).The definition of (CRRT) is any extracorporeal blood purification therapy intended to substitute for impaired renal function over an extended period of time and applied for or aimed at being applied for 24 hours/day, Bellomo R., Ronco., Mehata R. The CRRT was found because the traditional way of ...
has mutated. This mutation results in distorted, “sickle-shaped” cells, which often get trapped in the blood vessels of the body. Because of this, a sickle cell patient can have severe oxygen deprivation resulting in extreme pain. Oxygen is necessary to survive and thrive, but when a person doesn’t receive enough oxygen to any part of the body, the consequences are excruciating.
Discussion: The results acquired from the experiment have supported the hypothesis. In the first sample, red blood cell in the isotonic solution (NaCl 0.85%) kept its regular shape. This is because when RBC was placed in an isotonic solution, which is the solution has the same concentration of solutes as the cell, water will move into and out of the cell simultaneously and no net effect will be seen. In the second sample, cell shrank, and crenation occurred in the hypertonic solution (NaCl 10%) because the hypotonic solution has a higher osmosis pressure than the cell, water is going to escape from the cell for decreasing the high concentration of solute in the hypotonic solution. Lastly, in the hypertonic solution (NaCl 10%), cell bloated,
As the kidneys regulate the quantity of fluid which leaves the body, patients who suffer from kidney disease progression, may be not be able to regularize fluid removal from their body. Due to this scenario, their physician or specialist may ask them to reduce their intake of fluid. Lowering daily fluid intake for the renal diet involves: not drinking to socialize or from habit, only having a drink when thirsty, and sucking on a wedge of lemon or chips of ice. It also entails taking measures for monitoring the quantity of fluid that is drunk. This is done by measuring a regularly used glass or cup to measure the quantity of fluid it holds, as well as placing the recommended daily quantity of water into a specific container, and then only taking the fluid that is consumed from this. This insures that the recommended amount is not exceeded (Medical
They were often administered at night when his room would be dark and he could not see the bag of packed red blood cells hanging from his intravenous (IV) infusion pump pole. He was receiving narcotic pain medicine resulting in very mild sedation and causing him to sleep more. Jose was also persistently febrile and overall did not feel well so his wakefulness and alertness were decreased. If he questioned what was hanging from his IV pole or why his vital signs needed to be checked again, he was told it was a different type of IV fluid or a different type of medication he needed to
