Hyaline membranes help to the development of fibrosis and atelectasis (collapse) essential to decrease in gas exchange capability and lung dysfunction. These changes cause the lungs to become stiff, patient work hard to inspire. Hypoxemia and the stimulation of juxtacapillary receptors in the stiff lung parenchyma leading to increase respiratory rate and decrease in tidal volume. Breathing irregular increase carbon dioxide removal,
The diastolic dysfunction will eventually lead to right-sided heart failure. Pulmonary edema or congestion happens when the left ventricle of the heart fails. This is simply because the inefficiency of its ventricle to pump effectively causes the blood to back up to the pulmonary capillaries as the pulmonary venous blood rises its pressure into the tissues and alveoli impairing the gas exchange. Pulmonary congestion will be manifested in crackles, difficulty of breathing, frothy pink-tinged sputum and shortness of breath. In addition, the decreased amount of blood ejected from the left side causes ineffective tissue perfusion.
Another indication of fluid build up would have been to auscultate the lungs for crackles during breath sounds. Increased pressure in the arterioles, means an increased after load for the right ventricle, moreover, causing the right ventricle to dysfunction. The patients history of lung disease means that any pressure in the
The blood flow and oxygen flow is incorrect or in simple words, the current of blood stops flowing through you body correctly. WHAT IS THE ISCHEMIA DISEASE Ischemia Heart Disease or Coronary Heart Disease is the narrowing of the blood vessels that supply the heart with blood and oxygen. These Arteries Include: 1. Left Anterior Descending Artery 2. Left Circumflex Artery 3.
Myocardial perfusion imaging: Myocardial perfusion imaging (MPI) is a form of functional cardiac imaging, used for the diagnosis of ischemic heart disease. The underlying principle is that under conditions of stress, diseased myocardium receives less blood flow than normal myocardium. MPI is one of several types of cardiac stress test. A cardiac specific radiopharmaceutical is administered. E.g.
Self-directed Learning Assignment Justin Rice Disease: Idiopathic Pulmonary Fibrosis 1. Introduction: In class, we have discussed many different respiratory diseases and they usually fall into one of two categories: obstructive and restrictive. Obstructive disease is characterized by less air flow and difficult expiration while restrictive disease is characterized by difficulty getting air in and reduced lung volumes. The disease I have chosen to research is idiopathic pulmonary fibrosis. This is a disease that is caused by scarring of lung tissue over time due to an unknown reason.
The pleural space begins to fill causing the-the mediastinum to maneuver around, which can lead to disruption of the airflow and pulmonary circulation. Once the air circulation is disrupted the patient begins to compensate. Tension pneumothorax can be misleading if not realizing to symptoms. A patient with tension pneumothorax is going to have chest pain caused by the lung collapsing. The patient will experience respiratory distress causing the patient to breath faster because they are not getting the proper amount of oxygen, respiratory distress can lead to altered mental status and diminished breath
Hypovolemic shock is the body’s response to a significant loss of fluids that disrupts the volume of blood within the body the body, causing disturbance in normally functioning systems. The most common cause of such response is from rapid loss of fluids, such as with hemorrhage, a sudden acute blood loss that can be externally or internally found throughout the human body (Tortura 781). Hypovolemic shock will then come secondary to hemorrhagic shock, the body’s initial response rapid blood loss as a way of trying to slow down or stop bleeding. When blood loss cannot be controlled with hemorrhagic shock, hypovolemic shock is then initiated (Kolecki, “Background”). However, significant fluid loss can also cause in relation to hypovolemic shock can occur in other ways, such as with excessive sweating, diarrhea, vomiting, or from a lack of fluid intake (Tortura 781).
The priorities are to detect intraoperative MI early, give effective treatment, and transfer the patient to ICU urgently for further cardiac care.  When myocardial ischemia is because of hypovolemia, hypotension should be primarily managed with IV fluids in the form of crystalloids or colloids and blood products. Inotropic support is required when there is no response to fluid administration.In this case myocardial ischemic changes were because of hypovolemic shock. Hence by correcting hypotension secondary to hypovolemia the myocardial ischemic changes were reversed.
These stresses cause a pressure overload which induce changes in myocardial structure and function. This initially acts a compensatory mechanism but when pressure overload persists it can lead to the development of cardiac hypertrophy (Lyon et al., Mechanotransduction in Cardiac Hypertrophy and Failure) . Cardiac hypertrophy is strongly associated with in an increased risk of several severe cardiovascular events, including stroke, coronary heart disease and heart failure (Gosse,
