4 Risk Recognition and Prioritization
Learn to recognize instability, prioritize immediate and time-sensitive threats, and reassess patients as their condition changes.
Recognizing immediate danger
A patient's first reported problem is not necessarily the most urgent. Decide priorities by asking whether there is an immediate threat to life, limb, or organ function; whether the patient could deteriorate quickly; and whether time-dependent treatment or escalation is needed.
Priorities are provisional. is a repeated estimate of urgency, so worsening findings require reprioritization rather than reliance on an earlier low-acuity impression.
Using the sequence
For a deteriorating or critically ill patient, use the sequence. Treat an immediately life-threatening problem as soon as it is found, summon appropriate help early, and continue the assessment. In trauma, follow local protocols for catastrophic external bleeding, which may need immediate control alongside the initial assessment. Reassess after each intervention.
A — Airway: Check whether the patient can speak. Look for obstruction, stridor, swelling, gurgling, or inability to protect the airway.
B — Breathing: Assess effort, rate, oxygenation, chest movement, and ability to speak. Severe distress, cyanosis, or very slow or very fast breathing is concerning.
C — Circulation: Check pulse, perfusion, skin, blood pressure, and visible bleeding. Heavy bleeding, a weak rapid pulse, or poor perfusion may indicate shock.
D — Disability: Assess responsiveness, mental status, and pupils; check blood glucose when appropriate and available. New confusion, reduced consciousness, or active seizure is a red flag.
E — Exposure and examination: Look for injuries, rash, bleeding, temperature abnormality, or other clues while preventing unnecessary heat loss and preserving dignity.

Escalate urgently for airway or breathing threats such as inability to speak normally, airway swelling or obstruction, severe respiratory effort, central cyanosis, or abnormal breathing. Circulatory warning signs include major bleeding, fainting with ongoing instability, a weak rapid pulse, poor perfusion, or suspected shock.
Neurologic threats include sudden facial or limb weakness, speech or vision change, new confusion, unresponsiveness, or seizure. Suspected stroke needs rapid emergency evaluation even if symptoms improve. Possible cardiac emergencies include acute chest discomfort or equivalent symptoms such as shortness of breath, sweating, nausea, or lightheadedness, especially when accompanied by collapse or signs of poor perfusion.
Other threats include serious trauma, poisoning or dangerous exposure, a threatened limb, severe acute pain with concerning features, and pregnancy-related bleeding, severe pain, seizure, or altered mental status. These warning signs are not a complete diagnostic checklist.
Do not use a single reassuring measurement to rule out serious illness. Consider the whole presentation, relevant history, and change over time. Vital-sign thresholds and criteria vary by age, setting, and protocol; use approved local tools and clinical judgment. The WHO framework identifies airway or breathing compromise, circulatory impairment, altered mental status, active convulsions, and high-risk trauma as high-acuity concerns.
Prioritizing competing problems
When problems compete, address immediate threats first, then identify time-critical concerns, stabilize before investigating, and turn to less urgent needs once immediate threats are managed.
Immediate threats: Address cardiac arrest, a threatened airway, severe breathing failure, major hemorrhage, or rapidly worsening consciousness; activate emergency support.
Time-critical threats: Rapidly identify concerns such as suspected stroke, acute coronary syndrome, sepsis, serious trauma, or poisoning, and initiate the relevant emergency pathway.
Stabilize, then investigate: Perform focused checks and gather history without delaying interventions or escalation needed to protect life or function.
Less urgent problems: Once immediate threats are managed, assess pain, injuries, chronic conditions, and other needs.
When possible, delegate parallel tasks such as calling for help, obtaining vital signs, or preparing equipment while one person maintains an overview of the patient. Communicate the concern, key findings, trend, actions taken, and help needed clearly. Emergency systems distinguish patients needing immediate care from those who can safely wait.
For example, if a patient reports chest pressure and also has a painful ankle, assess and escalate the possible cardiac emergency first. The ankle can wait unless examination reveals a separate immediate threat, such as uncontrolled bleeding or loss of circulation. Prioritize by risk and urgency, not by the number of complaints or their order of presentation.
and changing priorities
After an intervention and whenever the patient's condition changes, repeat relevant checks and vital signs. Assess whether breathing, perfusion, responsiveness, symptoms, and overall appearance have improved, stayed the same, or worsened. If the patient deteriorates, escalate again; do not let an earlier low-acuity impression delay . Regular helps judge treatment effects and identify when additional help is needed.
If a person is unresponsive and not breathing normally, treat this as possible cardiac arrest: activate the emergency response and begin CPR/AED actions according to training and local protocol. Gasping is not normal breathing.
