Signs and Symptoms of Heart Failure: Are You Asking the Right Questions? Cardiovascular Critical Care SIGNS AND SYMPTOMS OF HEART FAILURE: ARE YOU ASKING THE RIGHT QUESTIONS? By Nancy Albert, PhD, CCNS, CCRN, NE-BC, Kathleen Trochelman, RN, MSN, Jianbo Li, PhD, and Songhua Lin, MS Background Patients may not verbalize common and atypical signs and symptoms of heart failure and may not understand their association with worsening disease and treatments. Objectives To examine prevalence of signs and symptoms relative to demographics, care setting, and functional class. Methods A convenience sample of 276 patients (164 ambula- tory, 112 hospitalized) with systolic heart failure completed a 1-page checklist of signs and symptoms experienced in the preceding 7 days (ambulatory) or in the 7 days before hospital- ization. Demographic and medical history data were collected. C E 1.0 Hour Results Mean age was 61.6 (SD, 14.8) years, 65% were male, 58% were white, and 45% had ischemic cardiomyopathy.

The incidence of heart failure continues to increase, with 660000 new cases diagnosed annually in adults aged 45 and over. For men and women at age 40, the lifetime risk of heart failure developing is currently 1 in 5.1 Thus it is important for health care providers to better understand the signs and symp- Htoms of heart failure so that diagnosis is not missed at first presentation and worsening status is identified early and treated promptly. Additionally, common signs and symptoms of heart failure may be well known to health care providers who treat heart failure routinely, but atypical signs and symptoms associated with worsening status may not be recognized at presentation.

Key Messages Purpose of review To evaluate home noninvasive positive pressure ventilation (NIPPV) in adults with chronic respiratory failure in terms of initiation, continuation, effectiveness, adverse events, equipment parameters and required respiratory services. Devices evaluated were home mechanical ventilators (HMV), bi-level positive airway pressure (BPAP) devices, and continuous positive airway pressure (CPAP) devices. Key messages • In patients with COPD, home NIPPV as delivered by a BPAP device (compared to no device) was associated with lower mortality, intubations, hospital admissions, but no change in quality of life (low to moderate SOE). NIPPV as delivered by a HMV device (compared individually with BPAP, CPAP, or no device) was associated with fewer hospital admissions (low SOE). In patients with thoracic restrictive diseases, HMV (compared to no device) was associated with lower mortality (low SOE).

  • Respiratory Insufficiency in Patients with ALS at Or Near the End of Life
    Amyotrophic lateral sclerosis (ALS) is a devastating motor neuron disease causing progressive paralysis and eventual death, usually from respiratory failure. Treatment for ALS is focused primarily on optimal symptom manage- ment because there is no known cure. Respiratory symptoms that occur are related to the disease process and can be very distressing for patients and their loved ones. Recommendations on the management of respira- tory insufficiency are provided to help guide clinicians caring for patients with ALS. Hospice and Palliative Care Feature The Management of Andrea L.

  • CT Children's CLASP Guideline
    CT Children’s CLASP Guideline Chest Pain INTRODUCTION . Chest pain is a frequent complaint in children and adolescents, which may lead to school absences and restriction of activities, often causing significant anxiety in the patient and family. The etiology of chest pain in children is not typically due to a serious organic cause without positive history and physical exam findings in the cardiac or respiratory systems. Good history taking skills and a thorough physical exam can point you in the direction of non-cardiac causes including GI, psychogenic, and other rare causes (see Appendix A). A study performed by the New England Congenital Cardiology Association (NECCA) identified 1016 ambulatory patients, ages 7 to 21 years, who were referred to a cardiologist for chest pain. Only two patients (< 0.2%) had chest pain due to an underlying cardiac condition, 1 with pericarditis and 1 with an anomalous coronary artery origin. Therefore, the vast majority of patients presenting to primary care setting with chest pain have a benign etiology and with careful screening, the patients at highest risk can be accurately identified and referred for evaluation by a Pediatric Cardiologist. INITIAL INITIAL EVALUATION: Focused on excluding rare, but serious abnormalities associated with sudden cardiac death EVALUATION or cardiac anomalies by obtaining the targeted clinical history and exam below (red flags): . Concerning Pain Characteristics, See Appendix B AND . Concerning Past Medical History, See Appendix B MANAGEMENT . Alarming Family History, See Appendix B . Physical exam: - Blood pressure abnormalities (obtain with manual cuff, in sitting position, right arm) - Non-innocent murmurs . Obtain ECG, unless confident pain is musculoskeletal in origin: - ECG’s can be obtained at CT Children’s main campus and satellites locations daily (Hartford, Danbury, Glastonbury, Shelton).

Mattera, M.S., R.N., EMT-P COGNITIVE OBJECTIVES Upon completion of the class, independent study materials and post-test question bank, each participant will independently do the following with a degree of accuracy that meets or exceeds the standards established for their scope of practice: 1. Integrate complex knowledge of pulmonary anatomy, physiology, & pathophysiology to sequence the steps of an organized physical exam using four maneuvers of assessment (inspection, palpation, percussion, and auscultation) and appropriate technique for patients of all ages. (National EMS Education Standards) 2. Integrate assessment findings in pts who present w/ respiratory distress to form an accurate field impression. This includes developing a list of differential diagnoses using higher order thinking and critical reasoning. (National EMS Education Standards) 3. Describe the signs and symptoms of compromised ventilations/inadequate gas exchange. 4. Recognize the three immediate life-threatening thoracic injuries that must be detected and resuscitated during the “B” portion of the primary assessment. 5. Explain the difference between pulse oximetry and capnography monitoring and the type of information that can be obtained from each of them. 6. Compare and contrast those patients who need supplemental oxygen and those that would be harmed by hyperoxia, giving an explanation of the risks associated with each. 7. Select the correct oxygen delivery device and liter flow to support ventilations and oxygenation in a patient with ventilatory distress, impaired gas exchange or ineffective breathing patterns including those patients who benefit from CPAP. 8.

    2/12/2015 Dyspnea, Orthopnea, and Paroxysmal Nocturnal Dyspnea ­ Clinical Methods ­ NCBI Bookshelf NCBI Bookshelf. A service of the National Library of Medicine, National Institutes of Health. Walker HK, Hall WD, Hurst JW, editors. Clinical Methods: The History, Physical, and Laboratory Examinations. 3rd edition. Boston: Butterworths; 1990. Chapter 11 Dyspnea, Orthopnea, and Paroxysmal Nocturnal Dyspnea Vaskar Mukerji. Definition Dyspnea refers to the sensation of difficult or uncomfortable breathing. It is a subjective experience perceived and reported by an affected patient. Dyspnea on exertion (DOE) may occur normally, but is considered indicative of disease when it occurs at a level of activity that is usually well tolerated. Dyspnea should be differentiated from tachypnea, hyperventilation, and hyperpnea, which refer to respiratory variations regardless of the patients" subjective sensations. Tachypnea is an increase in the respiratory rate above normal; hyperventilation is increased minute ventilation relative to metabolic need, and hyperpnea is a disproportionate rise in minute ventilation relative to an increase in metabolic level. These conditions may not always be associated with dyspnea. Orthopnea is the sensation of breathlessness in the recumbent position, relieved by sitting or standing. Paroxysmal nocturnal dyspnea (PND) is a sensation of shortness of breath that awakens the patient, often after 1 or 2 hours of sleep, and is usually relieved in the upright position. Two uncommon types of breathlessness are trepopnea and platypnea. Trepopnea is dyspnea that occurs in one lateral decubitus position as opposed to the other. Platypnea refers to breathlessness that occurs in the upright position and is relieved with recumbency. Technique A patient with dyspnea may say: "I feel short of breath," "I"m having difficulty breathing," "I can"t catch my breath," "I feel like I"m suffocating." Because it is a subjective phenomenon, the perception of dyspnea and its interpretation vary from patient to patient.
