    Mosby: Mosby's Nursing Video Skills

    Mosby: Mosby's Nursing Video Skills Procedural Guideline for Assessing Apical Pulse Procedure Steps 1. Verify the health care provider’s orders. 2. Gather the necessary equipment and supplies. 3. Perform hand hygiene. 4. Provide for the patient’s privacy. 5. Introduce yourself to the patient and family if present. 6. Identify the patient using two identifiers. 7. Assess for factors that can affect the apical pulse rate and rhythm, such as medical history, disease processes, age, exercise, position changes, medications, temperature, or sympathetic stimulation. 8. Gloves are only worn if nurse will be in contact with bodily fluids or the patient is in protective precautions. 9. Help the patient into a supine or sitting position, and expose the sternum and the left side of the chest. 10. Locate the point of maximal impulse (PMI, or apical impulse). To do this, find the angle of Louis, which feels like a bony prominence just below the suprasternal notch. 11. Slide your fingers down each side of the angle to find the second intercostal space (ICS). Carefully move your fingers down the left side of the sternum to the fifth intercostal space and over to the left midclavicular line. 12. Feel the PMI as a light tap about 1 to 2 centimeters in diameter, reflecting the apex of the heart. 13. If the PMI is not where you would expect, as in a patient whose left ventricle is enlarged, inch your fingers along the fifth intercostal space until you feel the PMI. 14. Remember where you felt the PMI: over the apex of the heart in the fifth intercostal space at the left midclavicular line.

Abstract Systolic blood pressure normally falls during quiet inspiration in normal individuals. Pulsus paradoxus is defined as a fall of systolic blood pressure of more than 10 mmHg during the inspiratory phase. Pulsus paradoxus can be observed in cardiac tamponade and in conditions where intrathoracic pressure swings are exaggerated or the right ventricle is distended, such as severe acute asthma or exacerbations of chronic obstructive pulmonary disease. Both the inspiratory decrease in left ventricular stroke volume and the passive transmission to the arterial tree of the inspiratory decrease in intrathoracic pressure contribute to the occurrence of pulsus paradoxus. During cardiac tamponade and acute asthma, biventricular interdependence (series and parallel) plays an important role in the inspiratory decrease in left ventricular stroke volume.

  • Arrhythmia What Is It?

    Arrhythmia What Is It?

    Arrhythmia What is it? Most of us have felt our heart race or skip a beat. It’s fairly normal every once and a while. But for some people, it’s a sign of arrhythmia – a disorder of your heart rate or rhythm – that needs to be checked out by a specialist. If you have an arrhythmia (there are multiple types), your heart either beats: • too fast • too slow or • with an irregular pattern Did You Know? This change in your heart rhythm is usually caused by a “glitch” Our heart beats an average of in your heart’s electrical activity, which tells the heart when to 70 to 80 times a minute and contract and pump blood to the body. Your heart doesn’t beat over 100,000 times a day! It’s with the regularity of a Swiss watch, and many factors can cause no wonder millions of people an irregularity. notice palpitations such as skipping a beat, fluttering or a Some of these factors include: racing heart. • having had a heart attack • having heart failure • blood chemistry imbalances • abnormal hormone levels • alcohol, caffeine and other substances or medicines • a variety of inherited abnormalities 8 Tips for Staying Heart Healthy with Arrhythmias Living with an arrhythmia varies tremendously from one person to the next. It will depend on the type of arrhythmia you have, how serious it is and the recommended treatment. Some people can take a single medication to correct their heart’s rhythm; others undergo electrophysiology studies or require a pacemaker or implantable defibrillator. No matter what kind of arrhythmia you have, there are things you can do to keep your heart healthy and ticking as it should.
  • Jugular Venous Pressure

    Jugular Venous Pressure

    NURSING Jugular Venous Pressure: Measuring PRACTICE & SKILL What is Measuring Jugular Venous Pressure? Measuring jugular venous pressure (JVP) is a noninvasive physical examination technique used to indirectly measure central venous pressure(i.e., the pressure of the blood in the superior and inferior vena cava close to the right atrium). It is a part of a complete cardiovascular assessment. (For more information on cardiovascular assessment in adults, see Nursing Practice & Skill ... Physical Assessment: Performing a Cardiovascular Assessment in Adults ) › What: Measuring JVP is a screening mechanism to identify abnormalities in venous return, blood volume, and right heart hemodynamics › How: JVP is determined by measuring the vertical distance between the sternal angle and the highest point of the visible venous pulsation in the internal jugular vein orthe height of the column of blood in the external jugular vein › Where: JVP can be measured in inpatient, outpatient, and residential settings › Who: Nurses, nurse practitioners, physician assistants, and treating clinicians can measure JVP as part of a complete cardiovascular assessment What is the Desired Outcome of Measuring Jugular Venous Pressure? › The desired outcome of measuring JVP is to establish the patient’s JVP within the normal range or for abnormal JVP to be identified so that appropriate treatment may be initiated. Patients’ level of activity should not be affected by having had the JVP measured ICD-9 Why is Measuring Jugular Venous Pressure Important? 89.62 › The JVP is

    The Carotid Bruit on September 25, 2021 by Guest

    AUGUST 2002 221 Pract Neurol: first published as 10.1046/j.1474-7766.2002.00078.x on 1 August 2002. Downloaded from INTRODUCTION When faced with a patient who may have had a NEUROLOGICAL SIGN stroke or transient ischaemic attack (TIA), one needs to ask oneself some simple questions: was the event vascular?; where was the brain lesion, and hence its vascular territory?; what was the cause? A careful history and focused physical examination are essential steps in getting the right answers. Although one can learn a great deal about the state of a patient’s arteries from expensive vascular imaging techniques, this does not make simple auscultation of the neck for carotid bruits redundant. In this brief review, we will therefore defi ne the place of the bruit in the diagnosis and management of patients with suspected TIA or stroke. WHY ARE CAROTID BRUITS IMPORTANT? A bruit over the carotid region is important because it may indicate the presence of athero- sclerotic plaque in the carotid arteries. Throm- boembolism from atherosclerotic plaque at the carotid artery bifurcation is a major cause of TIA and ischaemic stroke. Plaques occur preferentially at the carotid bifurcation, usually fi rst on the posterior wall of the internal carotid artery origin. The growth of these plaques and their subsequent disintegration, surface ulcera- tion, and capacity to throw off emboli into the Figure 1 Where to listen for a brain and eye determines the pattern of subse- bifurcation/internal carotid quent symptoms.
