English for Emergency Nursing: Essential Vocabulary & Phrases

"triage"

The process of rapidly sorting patients by the urgency of their condition to prioritise treatment when resources are limited

"The triage nurse assessed the patient's airway, breathing, and circulation within 30 seconds of arrival and assigned a category-two priority."

"chief complaint"

The patient's primary reason for attending the emergency department, expressed in their own words and used to guide initial assessment

"The chief complaint documented on arrival was "sudden severe headache unlike any I have had before," which prompted immediate CT head imaging."

"presenting problem"

The clinical description of the condition that brought the patient to the emergency department, as interpreted by the assessing nurse

"The presenting problem was an acute exacerbation of asthma with a peak flow of 40% predicted, requiring immediate nebulised bronchodilator therapy."

"acuity level"

A numerical or colour-coded rating that reflects the urgency and severity of a patient's condition and determines how quickly they must be seen

"Patients with an acuity level of one are resuscitation cases who require immediate intervention upon arrival to the emergency department."

"vital signs"

Objective measurements of essential body functions—heart rate, blood pressure, respiratory rate, temperature, and oxygen saturation—used to detect deterioration

"Serial vital signs documented every 15 minutes revealed a progressive rise in heart rate and fall in blood pressure consistent with developing shock."

"pain scale"

A standardised tool, such as the 0–10 numerical rating scale, used to quantify a patient's reported pain intensity and guide analgesia decisions

"The patient rated abdominal pain at 9 out of 10 on the pain scale, prompting rapid analgesia administration before further diagnostic workup."

"early warning score"

A composite score calculated from vital sign parameters that identifies deteriorating patients and triggers escalation to senior clinical staff

"An early warning score of 7 activated the rapid response team and the patient was transferred to resuscitation bay for closer monitoring."

"mechanism of injury"

The physical forces or events responsible for causing a traumatic injury, used to predict injury patterns and guide examination

"The mechanism of injury—a high-speed motor vehicle collision with airbag deployment—raised suspicion for thoracic aortic injury despite an initially normal examination."

"cardiac arrest"

The sudden cessation of effective cardiac activity resulting in loss of pulse, consciousness, and normal breathing, requiring immediate CPR

"The patient went into cardiac arrest in the waiting area; the emergency nurse initiated chest compressions and called for the crash trolley."

"cardiopulmonary resuscitation"

A life-saving technique combining chest compressions and rescue breaths to maintain circulation and oxygenation during cardiac arrest

"Cardiopulmonary resuscitation was commenced at a rate of 30 compressions to 2 breaths, with minimal interruptions to chest compressions throughout the resuscitation attempt."

"return of spontaneous circulation"

The resumption of a detectable pulse following cardiac arrest and CPR, indicating successful initial resuscitation

"Return of spontaneous circulation was achieved after 14 minutes of CPR and three defibrillation attempts, and the patient was transferred to the intensive care unit."

"shockable rhythm"

A cardiac arrest rhythm—ventricular fibrillation or pulseless ventricular tachycardia—that is amenable to treatment with electrical defibrillation

"The monitor identified a shockable rhythm and the team delivered a 200-joule unsynchronised shock, resuming compressions immediately afterward."

"pulseless electrical activity"

A cardiac arrest state in which organised electrical activity is present on the ECG but no pulse is palpable, requiring CPR and treatment of reversible causes

"Pulseless electrical activity was identified and the team systematically worked through the 4Hs and 4Ts to find and treat any reversible cause."

"adrenaline administration"

The intravenous injection of adrenaline (epinephrine) every 3–5 minutes during cardiac arrest to increase coronary and cerebral perfusion pressure

"Adrenaline administration 1 mg IV was given after the third defibrillation attempt and repeated every four minutes for the remainder of the arrest."

"post-resuscitation care"

A structured bundle of interventions—including targeted temperature management, haemodynamic optimisation, and neurological monitoring—given after ROSC to improve survival

"Post-resuscitation care was initiated in the emergency department, including targeted temperature management at 36°C and early coronary angiography referral."

"do not resuscitate order"

A documented medical decision that CPR should not be attempted in the event of cardiac or respiratory arrest, based on patient wishes and clinical appropriateness

"The senior emergency physician reviewed the patient's advance care plan and confirmed the do not resuscitate order with the family before discontinuing active resuscitation."

"airway obstruction"

A partial or complete blockage of the upper or lower airway that impairs breathing, caused by foreign bodies, secretions, soft tissue, or anatomical abnormalities

"de-escalation"

A verbal and non-verbal communication technique used to reduce agitation, aggression, or distress in a patient without the use of restraint or sedation wherever possible

"The experienced emergency nurse used de-escalation strategies—speaking calmly, reducing environmental stimuli, and validating the patient's feelings—to prevent a potentially violent situation."

"safe discharge planning"

A structured process ensuring that patients leaving the emergency department have appropriate follow-up, safety netting information, and access to crisis support if needed
