2. Explain the functions of the respiratory system. Cite the definitions and the differences between external and internal respiration. The respiratory system is responsible for bow we intake air into our bodies and out. It also helps provide oxygen to the body. External respirations is when you breathe in through your lungs and carbon dioxide exhaled out. Internal respirations is what you inhales goes from the lungs back to the heart.
Marty Smith is a 67-year-old male who has called 911 after experiencing chest pain and dizziness. The paramedics arrive and notice a bottle of nitroglycerin on the table. The patient states he has angina and is to take the medication as needed for chest pain. He took one pill an hour ago and a second pill 10 minutes prior to calling 911. Prior to this evening’s chest pain, he ate at a buffet and consumed 4 whiskey drinks. His ECG is not indicative of a myocardial infarction.
Cardiomyopathy can occur from the lack of dystrophin on the heart muscles. Cardiomyopathy makes it difficult for the patient to breathe. The heart becomes weak and swollen. It is not able to pump enough blood throughout the body, which will cause life-threatening results.
Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart 's pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The left ventricle supplies most of the heart 's pumping power, so it 's larger than the other chambers and essential for normal function. (American Heart Association). In left-sided or left ventricular heart failure, the left side of the heart must work harder to pump the same amount of blood. There are two types of left-sided heart failure: systolic heart failure and diastolic heart failure. Heart failure can arise from
“A DNAR form is a document issued and signed by a doctor, telling your medical team not to attempt cardiopulmonary resuscitation (CPR).” (“ATTEMPT” 1). I will be covering the Definition of what a do not resuscitate order is. Why you would need a do not resuscitate order. Also How to get a do not resuscitate order from your doctor. DO NOT ATTEMPT RESUSCITATION ORDER should not be a health care alternative because it is not ethical, some are not mentally stable enough to make the decision, and having cardiac arrest does not help (“ATTEMPT” 1). It sets out in law how decisions should be made on behalf of a person who lacks capacity (Breault 1).
In here article “Sudden Death: Proposed EKG Screening For Student Athletes Spurs Medical Debate,” Laura Beil focuses on the importance and controversial of student athletes receiving an electrocardiogram (EKG) prior to participating in sports activities. The EKG would check for a condition called cardiomyopathy, “Cardiomyopathy (KAR-de-o-mi-OP-ah-thee) refers to a disease of the heart muscles. There are many forms of cardiomyopathy, such as dilated cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic cardiomyopathy and hypertrophic cardiomyopathy. Other forms are often referred to as unclassified types. Hypertrophic Cardiomyopathy is the focus point in this article.
Heart Failure (HF) occurs when the heart is unable to pump the necessary volume of blood to meet demands of tissue metabolism. This condition can be acute; it may have a fast onset or clinical change of signs and symptoms (Andrietta, Moreira, & Barros, 2011). The patient with heart failure presents with shortness of breath, cough, or difficulty breathing on activity. The patient often experiences acute exacerbation of symptoms resulting in hospitalization for medical management. Congestive Heart Failure (CHF) continues to be a major public health problem associated with high morbidity and mortality. There are 5 million people in the United States with heart failure and an estimated 400,000 to 550,000 new patients are diagnosed each year. Annual
Dextrocardia is a rare heart condition where the hearts points to the right instead of the left side of the chest. It is congenital meaning person who has it was born with it. Less than one percent of the population is born with dextrocardia.
If the blood flow isn 't restored in time the restricted heart muscles, they begin to die thus this is the start of a heart attack. The dying of the heart muscles is known as infarction. If to many heart
The inflammation of muscle tissue in the heart is called Carditis, and these inflammation is arranged into three different types of categories depending on the location of the inflammation. These different type of inflammation are known as Endocarditis, Myocarditis, and Pericarditis. Within the three categories they all have similar diagnosis and similar formulas in diagnosing the inflammation. Carditis are to be indicated as the inflammation of the heart muscle and Pancarditis is to be presented as the inflammation of the whole heart.
Heart failure is when the heart is not functioning properly and becomes unable to supply the body properly with oxygen. Congestive heart failure is when this lack of function begins affecting the lungs ability to function normally by filling the alveoli with fluid. During normal functioning of the cardiovascular system, blood arrives at the right atrium of the heart via the vena cava. The right atrium empties blood into the right ventricle, which pumps it’s contents into the arterioles surrounding the alveoli of the lungs. From the lungs, the blood voyages to the left atrium of the heart. From there it is dumped into the left ventricle, which pumps it back out to the body eventually reaching the vena cava and thus completing the cycle.
The heart is a muscular organ the size of a clenched fist situated in the middle of the chest tilted slightly to the left. The heart receives its own oxygenated blood supplied by the coronary arteries and the coronary veins that take away the deoxygenated blood. The heart is made up of four chambers the left and right atrium and the left and right ventricle. The oxygenated blood travels from the lungs through the pulmonary veins, the pulmonary vein are the only veins in the body that carry oxygenated blood to the heart, the blood then enters the left atrium the blood is then pushed through the bicuspid valve, where the blood now enters the left ventricle where the blood is then pumped through the aortic valve into the aorta where the oxygenated
Acute myocardial infarction/coronary artery disease is when the arteries that supply the myocardium are clogged up; the heart cannot pump blood effectively to adequately perfuse vital organs and peripheral tissues. It affects the arteries that provide blood oxygen, and nutrients to the myocardium. When blood flow through the coronary arteries is partially or completely blocked, ischemia and infarction of the myocardium could occur. Nitroglycerin (NTG) increases collateral blood flow, redistributes blood flow toward the sub endocardium, and dilates the coronary arteries. In addition, it decreases myocardial oxygen demand by peripheral vasodilation, which decreases both preload and afterload.
When the heart 's pumping power starts to move slower than normal is what heart failure is. Some people like to think it is when the heart stops working because they think failure means stop working. Heart failure causes the pumping of blood to move way slower and that leads to the pressure in the heart to increase. Which this then results in the heart not pumping enough oxygen and nutrients to meet the body’s requirements. The chambers in the heart then may proceed by stretching to hold more blood so it can be pumped throughout the body or become stiff and thickened, which this helps by having a continue
Heart failure can be caused by abnormalities in systolic function leading to a defect in expulsion of blood or a diastolic function abnormality that leads to an abnormal ventricular filling. The most common form is associated with altered systolic inotropismului. Less commonly found is the ability ventricular diastolic failure to accept blood is altered. It may be the result of abnormal relaxation, short, incomplete or slow that may be transient as in acute ischemia or myocardial hypertrophy claim that restrictive cardiomyopathy secondary concentric or infiltrative diseases such as amyloidosis.
