A complete blood count was done for this patient upon admission in order to give a baseline to help guide the patient’s care. The blood count also can show how the hematological system was affected by the trauma that the patient suffered in the motor vehicle accident he was in. If the patient was hemodynamically unstable, he may have needed blood transfusions to bring the blood counts up. In later tests, the patient had an increase in white blood cell counts could indicate infection, possibly of the injuries he had sustained. The patient also underwent surgery to correct the injury to his spine, causing more blood to be lost in the process. The platelet, hemoglobin, and hematocrit counts could help to show if the patient was suffering from …show more content…
Increases in carbon dioxide and decreases in oxygen result in respiratory acidosis, or a decrease in pH of the blood, while decreases in carbon dioxide and increases in oxygen result in respiratory alkalosis, or an increase in blood pH (Workman, 2016). The metabolic component looked at by the arterial blood gas test is the amount of bicarbonate in the blood. Bicarbonate works with the hydrogen ions to balance pH, and decreases in bicarbonate can create metabolic acidosis while an increase in bicarbonate can result in metabolic …show more content…
The coagulation studies show the clotting abilities of the blood and the amount of time it takes for the blood to clot. It is important for the blood to clot in order to prevent blood loss. However, if the factors tested by the coagulation test are not within the normal ranges, the patient is at risk for excessive bleeding or even unwanted blood clots in the body. The coagulation test is also done with patients who are on anticoagulant therapies. The results are used to adjust the doses, and the normal ranges are adjusted to reflect the fact that an anticoagulant is in use to prevent unnecessary blood clots, such as those that cause deep vein thrombosis and pulmonary embolism. The patient however was not on any anticoagulant medication therapies. The test was repeated after surgery in order to make sure no therapy was needed to prevent future clots from

After a thorough examination, J.P. was diagnosed with a deep vein thrombosis (DVT). “DVT develops most often in the legs but can occur also in the upper arms…” (Ignatavicius & Workman, 2013). Due t...
Is there compensation occurring? Compensation is not occurring. Both values indicate acidity because there is too much CO2 and there is also too little HCO3. In regards to respiratory compensation, his breathing is impaired from asthma. Because the respiratory response to changes in HCO3 occurs much faster than metabolically, there is only one predicted compensatory response for primary metabolic acid-base disorders. Renal compensation, however, takes several days to occur, and would require an increase in HCO3.
The human body is dependent on interconnectedness of its systems to maintain homeostasis. Internal and external factors can potentially contribute to a disruption of homeostasis. If the body is not returned to homeostasis by negative feedback mechanisms then complications arise which can be detected by a battery of tests (Museum of Science & Industry, 2013). For example, a 40-year-old man enters the clinic with complaining of chest pains, the negative feedback systems have not returned the body to homeostasis. A variety of tests are performed to determine what is occurring. The objective data states that the patient has elevated troponin levels, which confirm a mild heart attack. Hematocrit levels are normal; however, platelet counts are recorded at >600x 103 /µl, and there is also no direct evidence for iron deficiency. Subjective data reveals that the patient complains of a throbbing and burning sensation in the hands and feet, and his family has a history of heart problems. To determine the patient’s condition the attending physician must understand the anatomy of the body.
Normally fibrin, the primary protein involved in clot formation, functions under the influence of regulatory mechanisms such as the anticoagulant protein antithrombin III and the enzyme plasmin, which is involved in the breakdown of clot formation in a process known as fibrinolysis (Levi, 2013). As the body’s regulation of clot formation and disintegration becomes disrupted in DIC, micro thrombi development and uncontrolled bleeding due to consumption coagulopathy, a lack of available clotting factors in the blood, occur which is a life threatening
In septic patients, increased levels of PAI-1 inhibit plasminogen activator (t-PA), which converts plasminogen to plasmin. Release of fibrin inhibits fibrinolysis by activation of thrombin-activatable fibrinolysis inhibitor (TAFI). In addition, the release of PAF causes platelet aggregation. This combination of inhibition of fibrinolysis, fibrin strand production and platelet aggregation contribute to a state of coagulopathy. This can lead to microcirculatory dysfunction with isolated or multiple organ dysfunction and cell death. Mr Hertz’s coagulation profile showed a fibrinogen level of 5.6 g/L, indicating that coagulopathies were underway in his system.
In order to function properly your body relies on oxygen. (O'Connell, K. (2017, March 13).) Whenever you take a breath in you allow oxygen into your lungs. When you release a breath you release carbon monoxide along with it. Respiratory alkalosis is when you breathe too fast or too deep and your carbon dioxide levels drop too low. This raises the pH of blood to pH levels above 7.45, making it become too alkaline. This is a common acid-base disorder in the elderly. This results from increased ventilation and may delay recovery, prolong hospitalizations, and affect clinical outcomes. (O'Connell, K. (2017, March
Respiratory Acidosis at its most basic definition is the retention of carbon dioxide (CO2) in the respiratory system, causing acidity in the arterial blood (Colbert, Ankey, & Lee, 2013).
Alveolar hyperventilation causes a decreased partial pressure of arterial carbon dioxide (PaCO2). The decrease in PaCO2 increases the ratio of bicarbonate concentration to PaCO2 which increases the pH level. The decrease in PaCO2 develops when a strong respiratory stimulus causes the respiratory system to remove more carbon dioxide than is produced. Respiratory alkalosis can be acute or chronic. Acute respiratory alkalosis is when the PaCO2 level is below the lower limit of normal and the serum pH is alkalemic. Chronic respiratory alkalosis is when the PaCO2 level is below the lower limit of normal, but the pH level is relatively normal or near normal. Respiratory alkalosis is the most common acid-base abnormality observed in patients who are critically ill. It is associated with numerous illnesses and is a common finding in patients on mechanical ventilation. Many cardiac and pulmonary disorders can occur with respiratory alkalosis. When respiratory alkalosis is present, the cause may be a minor or non–life-threatening disorder. However, more serious disease processes should also be considered in the differential diagnosis (Byrd, 2017). Hyperventilation is most likely the underlying cause of respiratory alkalosis. Hyperventilation is also known as over breathing (O’Connell, 2017).
Coagulation is a active process and the understanding of the blood coagulation system has progressed over the current years in anaesthetic practice. Regular coagulation pathway signifys an equilibrium between the pro-coagulant pathway that is accountable for clot development and the mechanisms that slow down the same beyond the injury site. Imbalance of the coagulation system may happen through serious illness, which may be secondary to many factors leading to a tendency of either thrombosis or bleeding
The current patient may be experiencing a range of traumatic injuries after his accident, the injuries that the paramedic will focus on are those that are most life threatening. These injuries include: a possible tension pneumothroax or a haemothorax, hypovolemic shock, a mild or stable pelvic fracture and tibia fibula fracture.
Transfusions of red blood cells, platelets, and plasma are critical to a patient's return to good health,
During the infusion of the second unit of blood transfusion, the nurse noticed that Mrs. Jones’ had a reaction all over her body which was rashes on the entire body and she was shivering. Her shivering indicates that Mrs. Jones may have fever or chill that are the sign and symptoms caused due to transfusion reaction (Potter, 2014). Mrs. Jones is complaining about pain in her lower back can cause an acute hemolytic reaction, and the other symptoms can be bloody urine, fever, flushing of the skin (Dugdale, 2017). “An acute hemolytic transfusion reaction is a serious problem that occurs after a patient receives a transfusion of blood. The red blood cells that were given to the patient are destroyed by the patient's immune system” (Dugdale, 2017).
When the lungs are unable to remove all of the carbon dioxide the body produces, it results in a condition called Respiratory Acidosis. This condition causes body fluid, especially the blood to be too acidic. There are levels of partial pressure of carbon dioxide (PCO2) in that shows whether or not the blood pH is balanced. “Normal levels adult/child: 35-45 mm Hg, Child less than 2 years: 26-41 mm Hg” (National Library, 2014). Elevated amounted of PCO2 indicates a sign of respiratory acidosis. HCO3; a concentration of hydrogen carbonate in the blood is used to determine along with pH (hydrogen ions) and CO2 source of acid base imbalance. “Normal levels of HCO3 and pH values are 22-26mmol/L and 7.35 - 7.45 respectively” (National Library, 2014).
The pKa of carbonic acid itself is only 3.8, so at the blood pH of 7.4, it is almost completely dissociated and theoretically unable to buffer and generate bicarbonate. However, carbonic acid can be replenished from CO2 in body fluids and air because the concentration of dissolved CO2 in body fluids is approximately 400 times greater than that of carbonic acid. As base is added and H+ is removed, H2CO3 dissociates into hydrogen and bicarbonate ions, and dissolved CO2 reacts with H2O to replenish the H2CO3. Dissolved CO2 is in equilibrium with the CO2 in air in the alveoli of the lungs, and thus the availability of CO2 can be increased or decreased by an adjustment in the rate of breathing and the amount of CO2
