FAST is a quick-screening approach to identify potential stroke and act fast. Face drooping signals weakness on one side of the face; have the person smile to spot asymmetry. Arm weakness is checked by asking them to stretch both arms straight ahead to see if one drifts downward. Speech difficulties include slurred speech or trouble speaking clearly. Time to call for help emphasizes calling emergency services immediately so the person can get urgent evaluation and treatment. The four elements together—Face drooping, Arm weakness, Speech difficulties, Time to call for help—provide a simple, rapid way to recognize a possible stroke and prompt fast action.

In suspected hypothermia, the priority is to prevent further heat loss and rewarm the patient carefully while protecting the heart from stresses that can trigger dangerous rhythms. Gentle handling is essential because rough movement can provoke arrhythmias in a cold, fragile heart. Removing wet clothing stops ongoing heat loss, and then rewarming should be gradual: use passive measures such as dry clothes, blankets, and a warm environment to conserve what’s left of the patient’s heat, followed by active external warming (like warming blankets or heat packs placed on the trunk) if available. Avoid rapid or direct heating to the chest or elsewhere with high heat, which can cause burns or push heat into the core too quickly and create complications like afterdrop. Continuous monitoring of vital signs and especially heart rhythm is crucial since hypothermia alters conduction and can lead to dangerous rhythms. If protocol allows, warmed IV fluids can aid internal rewarming and hydration; avoid cold IV fluids. In severe cases, follow hypothermia-specific resuscitation guidelines.

The concept being tested is how this system defines who counts as pediatric for specific protocols. In this SSV framework, a pediatric patient is someone fourteen years old or younger. This cutoff is used so that treatment, equipment sizing, and dosing align with pediatric guidelines, which differ from adult protocols. Once a patient is older than fourteen, adult protocols apply. So the maximum age for pediatric in SSV is fourteen years or younger.

The initial step in the EMS primary assessment is to make the scene safe and then quickly check airway, breathing, and circulation to identify any life threats. This approach focuses first on preventing harm to the responders and patient, then on finding conditions that could cause rapid deterioration. By assessing airway patency, breathing effectiveness, and circulation (including bleeding and signs of shock), you determine what needs immediate intervention—opening or protecting the airway, providing ventilation or oxygen, and controlling severe bleeding or improving circulation. These actions take priority over gathering a full history or waiting on other treatments. Checking blood glucose, obtaining a full patient history, or simply applying oxygen without first confirming life threats does not address the most urgent needs. The primary survey guides you to the critical, life-saving steps before moving on to the secondary assessment and more detailed history.

Subjective data are patient-reported symptoms and experiences, while objective data are measurable findings you can observe or obtain through examination and vital signs. In practice, if a patient says they have chest pain, dizziness, or nausea, that information is subjective. If you record a blood pressure, pulse, respirations, temperature, and observable signs like pallor, sweating, or abnormal lung sounds, those are objective. This distinction matters in EMS documentation because it separates what the patient feels from what you can verify through measurement and observation. Lab results fall under objective data, since they are test-derived measurements, and clinician impressions or rumors do not fit the defined data categories. Symptoms are subjective, whereas physical exam findings and vitals are objective.
