[…] doi: 10.1097/TME.0b013e3181946fd8 ARTICLE Abstract Author Information Authors Article Metrics Metrics Acute cardiogenic pulmonary edema (CPE) is a pathology frequently seen in patients presenting to emergency departments (EDs) and can usually be attributed [journals.lww.com]

Conclusions About 50% of patients with APE present respiratory fatigue. [academic.oup.com]

Introduction Acute pulmonary oedema may be the first presentation of heart failure or an exacerbation of existing known heart failure. [handbook.ggcmedicines.org.uk]

• Falling

  As their hypoxia worsens they may become agitated and with worsening respiratory failure may become hypercapnoeic causing their conscious level to fall. [rcemlearning.co.uk]

  […] striking feature of acute pulmonary edema: when the work of breathing is greatly intensified, increased ventilation may be associated with such large increases in CO 2 production from respiratory muscles that arterial pCO 2 actually rises instead of falling [academic.oup.com]

• Disability

  Infusion is commenced at 2-3mcg/kg/min and increased as required.(1) (d) Disability Morphine should be given early for patients who are agitated and distressed or complaining of chest pain. [rcemlearning.co.uk]

• Cough

  In each patient the onset of pulmonary edema was evidenced by acute dyspnea, cough, mental distress, and the development of râles throughout the lung fields. In one patient frothy pink sputum was expectorated. [annals.org]

• Orthopnea

  Shortness of breath can manifest as orthopnea (inability to lie down flat due to breathlessness) and/or paroxysmal nocturnal dyspnea (episodes of severe sudden breathlessness at night). [en.wikipedia.org]

• Hypotension

  Specifically, their use may dehydrate the euvolaemic patient and cause hyponatraemia and hypotension. [rcemlearning.co.uk]

  Cardiogenic shock (CS) is characterized by systemic hypoperfusion due to severe depression of the cardiac index ( 2 ) and sustained systolic arterial hypotension ( 18 mmHg). It is associated with in-hospital mortality rates 50%. [accessmedicine.mhmedical.com]

  Do not give opiate if patient is drowsy, exhausted or hypotensive. Give: furosemide IV 50mg (or in patients already receiving oral diuretics, give, intravenously, double the patient's normal oral dose). Repeat bolus at 30 mins to 1 hour. [handbook.ggcmedicines.org.uk]

• Gallop Rhythm

  The heart sounds may be inaudible over the rales from the lungs but a gallop rhythm may be present. Murmurs, especially mitral regurgitation and aortic stenosis, should be listened for, and may reveal a precipitating cause. [rcemlearning.co.uk]

In these cases, dobutamine is usually first-line treatment. [ncbi.nlm.nih.gov]
