Cardiopulmonary Resuscitation I: Adult

906
Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Cardiopulmonary Resuscitation IV: Pharmacological Management

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Cardiopulmonary Resuscitation III: AED Use

997
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

405
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Heart Failure Drugs: Inotropic Agents

1.7K
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...

Cardiomyopathy II: Dilated Cardiomyopathy

689
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Summary

Cardiology often overlooks end-of-life care. This review analyzes why "do not resuscitate" orders are underused by cardiac patients, despite their importance in managing end-of-life preferences.

Area of Science:

  • Cardiology
  • Geriatrics
  • Palliative Care

Background:

  • Cardiovascular diseases remain a leading cause of mortality.
  • Heart failure is a primary reason for hospitalization in older adults (>65 years).
  • Cardiology inadequately addresses end-of-life care planning.

Purpose of the Study:

  • To analyze the underutilization and misinterpretation of "do not resuscitate" (DNR) orders in cardiac patients.
  • To identify reasons why cardiac patients lack discussions about resuscitation preferences with physicians.

Main Methods:

  • Literature review and analysis of factors contributing to the underuse of DNR orders.
  • Examination of patient perceptions versus the reality of resuscitation outcomes.

Main Results:

  • Cardiac patients' understanding of prognosis and resuscitation outcomes often deviates from clinical reality.
  • "Do not resuscitate" orders are frequently underused and misunderstood in this population.
  • Limited opportunities exist for patients to discuss resuscitation preferences with their physicians.

Conclusions:

  • There is a critical gap in end-of-life care discussions for cardiac patients.
  • Addressing the underuse of DNR orders requires improved physician-patient communication.
  • Enhanced understanding and implementation of DNR orders are crucial for patient-centered cardiac care.
