I. Introduction

a. Background

An intensive care unit (ICU), also sometimes known as a critical care unit or an intensive therapy department is a special ward found inside most hospitals. It provides intensive care (treatment and monitoring) for people who are in a critically ill or unstable condition. Patients in ICUs need constant medical support to keep their body functions going. They may not be able to breathe on their own, and may have multiple organ failure, so medical equipment takes the place of these functions while they recover.

There are several circumstances in which a person may be admitted to intensive

care, for example, following surgery, or after an accident or severe illness. ICU beds are a

very expensive and limited resource because they provide specialized monitoring

equipment, a high degree of medical expertise and constant access to highly trained

nurses (usually one nurse for each bed). Being in an ICU can be a daunting experience

both for the patient and his or her friends and family. The healthcare professionals in

ICUs understand this and are there to help and support both patients and their families

during their time in intensive care.

Myocardial infarction (MI) is the irreversible necrosis of heart muscle secondary

to prolonged ischemia. This usually results from an imbalance of oxygen supply and

demand. The appearance of cardiac enzymes in the circulation generally indicates

myocardial necrosis. MI is considered, more appropriately, part of a spectrum referred to

an

acute coronary syndromes

(ACSs), which also includes

unstable angina

and

non–elevation MI (NSTEMI). Patients with ischemic discomfort may or may not have

ST-segment elevation. Most of those with ST-ST-segment elevation will develop Q waves.

Those without ST elevations will ultimately be diagnosed with unstable angina or

NSTEMI based on the presence of cardiac enzymes. MI may lead to impairment of

systolic function or diastolic function and to increased predisposition to arrhythmias and

other long-term complications.

b. General Objective

5. 11 Functional Health Pattern (Gordons) in NANDA

1. Health perception-Health Management Pattern

The patient was never ask a consultation at the Physician as long as he can stand alone and can walk. Until he woke up with vulnerable condition, the reason to seek a health management.

2. Nutritional-Metabolic Pattern

He doesn’t care, too much, what should be the food to be intake, and what not should be, too. He always telling his wife “ano na lang ang kakainin ko?!”. And now he is feeding thru NGT with low salt, low cholesterol and 1,800kCal. 3. Elimination Pattern

He used to commode at least once a day before he admit MICU, according to his wife. The physician ordered a Lactulose 30 cc to help him in bowel movement. 4. Activity-Exercise Pattern

The patient working as a carpenter, before his condition getting bad. At the MICU, helping the patient turning side-to-side every two hours, ordered by the physician, and do the passive R.O.M.

5. Sleep-Rest Pattern

2. Diagnostic procedure done, and possible to be done to the patient

Persistent chest pain, ST- segment changes on the electrocardiogram (ECG), and elevated levels of total creatinine kinase (CK) and the CK-MB isoenzyme over a 72 hour usually confirm an MI. Cardiac troponins are useful in differentiating an MI from skeletal muscle injury, or when CK-MB measurements are low and a small MI has actually occurred. Auscultation may reveal diminished heart sounds, gallops, and, in papillary dysfunction, the apical systolic murmur of mitral valve area. When signs and symptoms are equivocal, assume that the patient has had an MI until tests rule it out. Diagnostic test results include the following:

•

Serial 12-lead ECG: ECG abnormalities may be absent or inconclusive during

first few hours following an MI. When present, characteristics abnormalities include serial ST-segment depression in subendocardial MI and ST-segment elevation in a transmural MI.

•

Coronary Angiography: visualization reveals which vessels have been affected

and the extent of damage.

•

Serial serum enzyme levels: CK levels are elevated ; specifically, CK-MB or

troponin levels.

•

Myoglobin: because myoglobin always rises within 3-6 hours after an MI, lack of

an increase within 6 hours indicates that an MI hasn’t occurred.

•

Echocardiography: may show ventricular-wall motion abnormalities in patients

with a transmural MI.

•

Nuclear ventriculography (multigated acquisition scan or radionuclide ventriculography) scanning: Nuclear scanning can identify acutely damaged

muscle by picking up radioactive nucleotide, which appears as a “hot spot” on the film. It’s useful in localizing a recent MI.

•

Chest X-ray: venous congestion, cardiomegaly, and kerley’s B lines

•

Cardiac catheterization: show decrease cardiac output, increase in Pulmonary

arterial pressure, pulmonary artery wedge pressure and central venous pressure.

•

Auscultation: reveals holosystolic murmur and thrill. And also reveals a friction

rub.

Coronary Arteries. Because the heart is composed primarily of cardiac muscle tissue that

continuously contracts and relaxes, it must have a constant supply of oxygen and nutrients. The coronary arteries are the network of blood vessels that carry oxygen- and nutrient-rich blood to the cardiac muscle tissue. The blood leaving the left ventricle exits through the aorta, the body’s main artery. Two coronary arteries, referred to as the "left" and "right" coronary arteries, emerge from the beginning of the aorta, near the top of the heart. The initial segment of the left coronary artery is called the left main coronary. This blood vessel is approximately the width of a soda straw and is less than an inch long. It branches into two slightly smaller arteries: the left anterior descending coronary artery and the left circumflex coronary artery. The left anterior descending coronary artery is embedded in the surface of the front side of the heart. The left circumflex coronary artery circles around the left side of the heart and is embedded in the surface of the back of the heart. Just like branches on a tree, the coronary arteries branch into progressively smaller vessels. The larger vessels travel along the surface of the heart; however, the smaller branches penetrate the heart muscle. The smallest branches, called capillaries, are so narrow that the red blood cells must travel in single file. In the capillaries, the red blood cells provide oxygen and nutrients to the cardiac muscle tissue and bond with carbon dioxide and other metabolic waste products, taking them away from the heart for disposal through the lungs, kidneys and liver. When cholesterol plaque accumulates to the point of blocking the flow of blood through a coronary artery, the cardiac muscle tissue fed by the coronary artery beyond the point of the blockage is deprived of oxygen and nutrients. This area of cardiac muscle tissue ceases to function properly. The condition when a coronary artery becomes blocked causing damage to the cardiac muscle tissue it serves is called a myocardial infarction or heart attack.

Superior Vena Cava. The superior vena cava is one of the two main veins bringing

de-oxygenated blood from the body to the heart. Veins from the head and upper body feed into the superior vena cava, which empties into the right atrium of the heart.

Inferior Vena Cava. The inferior vena cava is one of the two main veins bringing de-oxygenated

blood from the body to the heart. Veins from the legs and lower torso feed into the inferior vena cava, which empties into the right atrium of the heart.

Aorta. The aorta is the largest single blood vessel in the body. It is approximately the diameter of

your thumb. This vessel carries oxygen-rich blood from the left ventricle to the various parts of the body.

Pulmonary Artery. The pulmonary artery is the vessel transporting de-oxygenated blood from

the right ventricle to the lungs. A common misconception is that all arteries carry oxygen-rich blood. It is more appropriate to classify arteries as vessels carrying blood away from the heart.

Pulmonary Vein. The pulmonary vein is the vessel transporting oxygen-rich blood from the

lungs to the left atrium. A common misconception is that all veins carry de-oxygenated blood. It is more appropriate to classify veins as vessels carrying blood to the heart.

Right Atrium. The right atrium receives de-oxygenated blood from the body through the

superior vena cava (head and upper body) and inferior vena cava (legs and lower torso). The sinoatrial node sends an impulse that causes the cardiac muscle tissue of the atrium to contract in a coordinated, wave-like manner. The tricuspid valve, which separates the right atrium from the right ventricle, opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle.

Right Ventricle. The right ventricle receives de-oxygenated blood as the right atrium contracts.

The pulmonary valve leading into the pulmonary artery is closed, allowing the ventricle to fill with blood. Once the ventricles are full, they contract. As the right ventricle contracts, the tricuspid valve closes and the pulmonary valve opens. The closure of the tricuspid valve prevents blood from backing into the right atrium and the opening of the pulmonary valve allows the blood to flow into the pulmonary artery toward the lungs.

Left Atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary

vein. As the contraction triggered by the sinoatrial node progresses through the atria, the blood passes through the mitral valve into the left ventricle.

Left Ventricle. The left ventricle receives oxygenated blood as the left atrium contracts. The

blood passes through the mitral valve into the left ventricle. The aortic valve leading into the aorta is closed, allowing the ventricle to fill with blood. Once the ventricles are full, they contract. As the left ventricle contracts, the mitral valve closes and the aortic valve opens. The closure of the mitral valve prevents blood from backing into the left atrium and the opening of the aortic valve allows the blood to flow into the aorta and flow throughout the body.

Papillary Muscles. The papillary muscles attach to the lower portion of the interior wall of the

ventricles. They connect to the chordae tendineae, which attach to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. The contraction of the papillary muscles opens these valves. When the papillary muscles relax, the valves close.

Chordae Tendineae. The chordae tendineae are tendons linking the papillary muscles to the

tricuspid valve in the right ventricle and the mitral valve in the left ventricle. As the papillary muscles contract and relax, the chordae tendineae transmit the resulting increase and decrease in tension to the respective valves, causing them to open and close. The chordae tendineae are string-like in appearance and are sometimes referred to as "heart strings."

Tricuspid Valve. The tricuspid valve separates the right atrium from the right ventricle. It opens

to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle. It closes as the right ventricle contracts, preventing blood from returning to the right atrium; thereby, forcing it to exit through the pulmonary valve into the pulmonary artery.

Mitral Value. The mitral valve separates the left atrium from the left ventricle. It opens to allow

the oxygenated blood collected in the left atrium to flow into the left ventricle. It closes as the left ventricle contracts, preventing blood from returning to the left atrium; thereby, forcing it to exit through the aortic valve into the aorta.

Pulmonary Valve. The pulmonary valve separates the right ventricle from the pulmonary artery.

As the ventricles contract, it opens to allow the de-oxygenated blood collected in the right ventricle to flow to the lungs. It closes as the ventricles relax, preventing blood from returning to the heart.

Aortic Valve. The aortic valve separates the left ventricle from the aorta. As the ventricles

contract, it opens to allow the oxygenated blood collected in the left ventricle to flow throughout the body. It closes as the ventricles relax, preventing blood from returning to the heart.

PHYSIOLOGY.

The heart is the muscular organ of the circulatory system that constantly pumps blood throughout the body. Approximately the size of a clenched fist, the heart is composed of cardiac muscle tissue that is very strong and able to contract and relax rhythmically throughout a person's lifetime. The heart has four separate compartments or

chambers. The upper chamber on each side of the

heart, which is called an atrium, receives and collects the blood coming to the heart. The atrium then delivers blood to the powerful lower chamber, called a ventricle, which pumps blood away from the heart through powerful, rhythmic contractions. The human heart is actually two pumps in one. The right side receives oxygen-poor blood from the various regions of the body and delivers it to the lungs. In the lungs, oxygen is absorbed in the blood. The left side of the heartreceives the oxygen-rich blood from the lungs and delivers it to the rest of the body.

Systole. The contraction of the cardiac muscle tissue in the ventricles is called systole. When the

The left ventricle empties into the aorta and the right ventricle into the pulmonary artery. The increased pressure due to the contraction of the ventricles is called systolic pressure. Diastole. The relaxation of the cardiac muscle tissue in the ventricles is called diastole. When the ventricles relax, they make room to accept the blood from the atria. The decreased pressure due to the relaxation of the ventricles is called diastolic pressure.

Right & Left Bundle Branches

The Sinoatrial Node (often called the SA node or sinus node) serves as the natural pacemaker for the heart. Nestled in the upper area of the right atrium, it sends the electrical impulse that triggers each heartbeat. The impulse spreads through the atria, prompting the cardiac muscle tissue to contract in a coordinated wave-like manner.

The impulse that originates from the sinoatrial node strikes the

Atrioventricular node (or AV node) which is situated in the

lower portion of the right atrium. The atrioventricular node in turn sends an impulse through the nerve network to the ventricles, initiating the same wave-like contraction of the ventricles.

The electrical network serving the ventricles leaves the atrioventricular node through the Right

and Left Bundle Branches. These nerve fibers send impulses that cause the cardiac muscle

tissue to contract.

`IV. Pathophysiology & Schematic Diagram. In an MI, an area of the myocardium is permanently destroyed; a condition in which the blood supply to the heart muscle is partially or completely blocked. The heart muscle needs a constant supply of oxygen-rich blood. The coronary arteries, which branch off the aorta just after it leaves the heart, deliver this blood. MI is usually caused by the reduced blood flow in a coronary artery of an atherosclerotic plaque and subsequent occlusion of the artery by a thrombus. Coronary artery disease can block blood flow, causing chest pain. In unstable angina and acute MI are considered to be the same process but different appoints along a continuum. specifically coronary atherosclerosis (literally “hardening of the arteries,” which involves fatty deposits in the artery walls and may progress to narrowing and even blockage of blood flow in the artery., As an atheroma grows, it may bulge into the artery, narrowing the interior (lumen) of the artery and partially blocking blood flow. With time, calcium accumulates in the atheroma. As an atheroma blocks more and more of a coronary artery, An atheroma, even one that is not blocking very much blood flow, may rupture suddenly. The rupture of an atheroma often triggers the formation of a blood clot (thrombus), the supply of oxygen-rich blood to the heart muscle (myocardium) can become inadequate. The blood supply is more likely to be inadequate during exertion, when the heart muscle requires more blood. An inadequate blood supply to the heart muscle (from any cause) is called myocardial ischemia. If the heart does not receive enough blood, it can no longer contract and pump blood normally. Other causes of MI include vasospasm, (sudden constriction or narrowing) of a coronary artery, decreased oxygen supply (e.g. from acute blood loss, anemia, or low blood pressure), and increased demand for oxygen (e.g. rapid heart rate, thyrotoxicosis, or ingestion of cocaine). In each case, a profound imbalance exists between myocardial oxygen supply and demand. The area of infarction develops over minutes to hours. As the cells are deprived of oxygen, ischemia develop, cellular injury occurs,, and the lack of oxygen results in infarction, or the death of cells. The area of the heart muscle supplied by the blocked artery dies.

preload/afterload, contractility, and cardiac work can be measured noninvasively with thoracic electrical bioimpedance (TEB) technique. Useful in evaluating response to therapeutic interventions and identifying need for more aggressive/emergency care. Provides information regarding progression/resolution of infarction, status of ventricular function, electrolyte balance, and effects of drug therapies.

Review chest x-ray.

Monitor laboratory data, e.g., cardiac enzymes, ABGs, electrolytes.

May reflect pulmonary edema related to ventricular dysfunction. Enzymes monitor resolution/extension of infarction. Presence of hypoxia indicates need for supplemental oxygen. Electrolyte imbalance, e.g., hypokalemia/hyperkalemia , adversely affects cardiac rhythm/contractility.

Potential problem

POTENTIAL CONSIDERATIONS following discharge from care setting (dependent on patient’s age, physical condition/presence of complications, personal resources, and life

responsibilities)

Activity intolerance —imbalance between myocardial oxygen supply/demand.

Grieving, anticipatory—perceived loss of general well-being, required changes in lifestyle, confronting mortality.

Decisional Conflict (treatment)—multiple/divergent sources of information, perceived threat to value system, support system deficit.

Family Processes, interrupted—situational transition and crisis.

Home Management, impaired—altered ability to perform tasks, inadequate support systems, reluctance to request assistance.

c. Discharge Planning use METHODS

Medications

 Promotes adherence measures by thoroughly explaining the prescribed medication regimen and other treatment measures.

 Warn the patients together with relatives about adverse reaction to drugs, and advise them to watch the sign and symptoms of toxic (nausea, anorexia, vomiting, and yellow vision)

Exercises

 Organize patient care and activities to maximize periods of uninterrupted rest.

 Assist with range-of-motion exercise. And turn him, every two hours, as ordered by physician.

 Don’t stress yourself, too much exercise. Enough, walk for 15 minutes. Treatment



Antiembolism stockings help prevent venostasis and thromboplebitis.  Encourage participation in a cardiac rehabilitation program.

 Watch for sign and symptoms of fluid retention (crackles, cough, tachypnea, and edema), which may indicate impending HF. Carefully monitor daily weight, intake and output, respiration, serum enzyme level and blood pressure.

Oxygenation and OPD follow up

 Oxygen administration at a modest flow rate for 3-6 hours. Diet of the patient

 Review dietary restriction with the patient. A low sodium, low fat, or low cholesterol diet and caffeine-free may be ordered, provide a list of food that he should avoid. Provide a clear liquid diet until nausea subsides. Ask dietitian to speak to the patient’s family.

Spiritual and sexual teaching

 Counsel patient to resume sexual activity progressively.

 Encourages the family to seek out religious activities, pertaining to spiritual issues.

Mr. Ephraim Mirafuentes & Staff Nurse (MICU): BELTRAN, JHON MARC

Highly competitive critical care nurse, that know how to assess, monitor and treat a critically ill patient, the better that patient’s chances are for early intervention. All of them excellence in the work environment. Their team using a method of habitual concentration our staff nurses could develop qualities of excellence for an improved outlook toward themselves, their work environment, and their profession. This improved outlook would lead to improved morale followed by an increase in retention within the unit, as well as progress in meeting our other goals. We recognized that our patient care, the attitudes of our nurses and staff, the helpfulness of peers, and even the cleanliness of the unit were based on tradition. During orientation, we learned what was expected of them in their individual units, and they continued this process by orienting others to the

same routines. As we recognized, we needed to improve ourselves in reality, in the world of Intensive care unit. Because we must aware that our work was in critical situation. As we are the nursing student that would be excited to us learning to do many activities in the role they accept, their life, around the Intensive care unit. We learned some nursing skills that we can used in critical situation.

We, my group, are glad to be your nursing student. Thanks you so much.

Medical Intensive Care Unit provides comprehensive and continuous care for patients who suffer from a serious illness or medical problem as well as social and psychological support for patients and their families. Their team includes board-certified, critical care physicians , highly trained nurses and other specialists who are specifically trained in critical care and provide round-the-clock care.

We learned some nursing skills using their equipment in an intensive care unit (ICU) includes mechanical ventilation to assist breathing through an endotracheal tube or a tracheotomy; intravenous lines for drug infusions fluids, nasogastric tubes, suction pumps, drains and catheters; and a wide array of drugs including their medication management.

Tadifa, Joleen

In MICU, patients are given 24-hour assessments by the healthcare team. Preparatory orders for the ICU generally vary from patient to patient since treatment is individualized. The initial workup should be coordinated by the attending ICU staff (intensiv and ICU nurse specialist), pharmacists (for medications and IV fluid therapy), and respiratory therapists for stabilization, improvement, or continuation of cardiopulmonary care. Well-coordinated care includes prompt consultation with other specialists soon after the patient is admitted to the ICU. The patient is connected to monitors that record his or her vital signs (pulse, blood pressure, and breathing rate). Orders for medications, laboratory tests, or other procedures are instituted upon arrival. The staff are highly skilled for critically ill patients. Using their advanced patient monitoring technology and sophisticated medical equipment, as providing continuous, comprehensive care for patients with serious conditions. providing expert healthcare and to treating patients with the compassion and respect they deserve.

Patients requiring intensive care usually require support for airway or respiratory compromise (such as ventilator support), potentially lethal cardiac dysrhythmias. Critical care nurse are giving their intensive care to the patient, support for the above are usually admitted for intensive/invasive monitoring. Ideally, intensive care is usually only offered to those whose condition is potentially reversible and who have a good chance of surviving with intensive care support. Since the critically ill are so close to dying, the outcome of this intervention is difficult to predict.
