Congestive Heart Failure (CHF) Congestive Heart Failure or CHF is a severe circulatory congestion due to decreased myocardial contractility, which results in the heart’s inability to pump sufficient blood to meet the body’s needs. In general, causes can be classified according to the following: a. Volume overload may cause the right ventricle to hypertrophy to compensate for added volume. b. Pressure overload usually results from an obstructive lesion, such as COA c. Decrease contractility can result from problems such as sever anemia, asphyxia, heart block and acidemia.
Invades nasopharynx where it replicates & spreads down to lower airway via aspiration of upper airway secretions. Causes necrosis of respiratory epithelium of small airways, peribronchiolar mononuclear infiltration & plugging of the lumens with mucus and exudate. The small airways become variably obstructed; this allows adequate inspiratory volume but prevents full expiration. This leads to hyperinflation & atelectasis. Serious alterations in gas exchange occur with arterial hypoxemia & CO2 retention resulting from mismatching of pulmonary ventilation (gas exchange w/in lungs) and perfusion.
Decreased compliance is a common feature in pulmonary conditions that scar lung tissue. F. How would fluid in Cari’s lungs affect her total lung capacity? Total lung capacity is the sum of vital capacity and residual volume. Her total lung capacity would decrease because
This can bring about shortness of breath, leg swelling (called edema), and different issues. Furthermore, organs in your body may not get the oxygen and supplements they have to work legitimately. Heart failure is a perpetual (progressing) condition that creates after some time. It is typically created by fundamental conditions, for example, hypertension or coronary illness. These conditions harm your heart, making the heart muscle hardened or thick.
Outcome 1 Know what a stroke is 1.1 Identify the changes in the brain associated with stroke Heart attacks and strokes are usually due to cardiovascular disease, a condition featuring body-wide damage to the delicate lining of the arteries the tubes that carry oxygen and nutrient-rich blood to all the organs, tissues and cells in your body and to the brain. The psychological, behavioural and emotional changes that take place after a stroke are part caused by physical damage to the brain. When the brain cells are damaged the sensations and parts of the body controlled by the cells can no longer function properly. This usually affects the left hand side of the body. But I personally have seen someone who has had a stroke and it has
Research Paper on Acute Respiratory Distress Syndrome Acute Respiratory Distress Syndrome, also known as ARDS is described as a restrictive lung disease that reduces compliance. This is a life threatening condition that causes severe fluid buildup in both lungs. The fluid buildup prevents the lungs being able to transfer oxygen from air into the body and carbon dioxide out of the body into the air. It is seen frequently in critical care and is associated with many medical diagnoses such as sepsis and trauma. Acute Respiratory Distress Syndrome is not considered to be a precise disease and is seen in an individual who demonstrates breathing failures due to an essential illness.
Since methemoglobin cannot carry oxygen, if enough too much of the enzyme is in the blood, the infant’s tissue and organs may be deprived of oxygen. This will cause him or her to develop a bluish coloring and possibly result in long-term digestive and respiratory
Congestive Heart Failure We all heard of congestive heart failure, but do you really know what congestive heart failure is? Congestive heart failure is when the heart isn’t able to pump enough blood or oxygen to meet your body’s need, do to other conditions that weaken or damage your heart. The term congestive heart failure comes from blood backing up into your liver, abdomen, lungs, and lower extremities. It can involve your left side of the heart and the right side of the heart or both sides. Left side failure is the most common failure which leads to fluids backing up in your lungs leading to shortness of breath.
PS124: Introduction to Psychology June 30, 2014 The disorder of the brain that I am interested in is a stroke. Stroke affects more than just the brain as well. A stroke occurs when blood flow to part of the brain is suddenly interrupted or when blood vessel in the brain bursts. Brain cells need oxygen and they die when they no longer receive oxygen and nutrients from blood. When your brain cells die from a stroke, abilities controlled by that area of the brain are lost.
At sea level, the air pressure is 760 mmHg. At 12,000 feet, the air pressure is at 483 mmHg. The difference between sea level and 12,000 feet yields us 40% fewer oxygen molecules per breath. Human Respiratory System The respiratory system is responsible for taking in oxygen into our
