Evaluation and management of the critically ill adult asthmatic in the emergency department setting
2021, American Journal of Emergency MedicineCitation Excerpt :Signs suggestive of severe exacerbation include tachypnea, tachycardia, accessory respiratory muscle use, inability to speak in full sentences, inability to lie flat, and tripoding position [14-17,50,51]. However, these findings possess a sensitivity of <50% for severe airway obstruction, and thus their absence should not be used to exclude the diagnosis of severe exacerbation [14,52]. Evidence of imminent cardiorespiratory arrest includes cyanosis, inability to maintain respiratory effort, bradycardia, and decreased mental status [16,17].
Outpatient Management for Acute Exacerbations of Obstructive Lung Diseases
2017, Medical Clinics of North AmericaCitation Excerpt :Pulsus paradoxus (>25 mm Hg), PEF less than 40% predicted, and arterial oxygen saturation <90% may be present. Notably, up to half of asthmatics with severe exacerbations lack these abnormalities4; thus, an absence of symptoms should not provide reassurance if the clinician suspects a severe exacerbation. Prompt identification of an exacerbation is critical for timely triage and treatment.
Asthma essentials
2013, African Journal of Emergency MedicineThe utility of serial peak flow measurements in the acute asthmatic being treated in the ED
2010, American Journal of Emergency MedicineCitation Excerpt :Such decisions usually depend on clinical examination, arterial blood gases, pulmonary function testing, and patient response to drug therapy. Many authors have argued that a strictly clinical assessment during an acute asthma exacerbation is less accurate than if pulmonary function testing was included in the judgment regarding severity and outcome [1-6]. Recent debate has centered on the reliability and accuracy of the different types of pulmonary function testing.
Intravenous magnesium sulphate provides no additive benefit to standard management in acute asthma
2008, Respiratory MedicineCitation Excerpt :The mainstay of current treatment is inhaled β2 agonists and systemic corticosteroids. However, up to one third of patients fail to respond adequately to β2 agonists3,4 and corticosteroids require 6–8 h before effects are manifest.5 Therefore, other agents for the treatment of acute asthma in the early stages may be beneficial.
