Nasal Cannula And Simple Mask Targets (Oxygen Delivery Ems) — EMS Field Guide for Paramedic Students

Medication considerations

Medication considerations include weight-based dosing where relevant, allergy verification, contraindications, route selection, and documentation of time, dose, and effect.

Documentation should read like a concise clinical story: chief complaint, key negatives, exam changes over time, interventions with dose and route, patient response, and handoff highlights including risks and pending items.

Transport/escalation

Transport and escalation should name destination capability, notification triggers, reassessment intervals en route, and criteria for priority transport.

Geriatric patients may present atypically: altered mental status can be infection, medication effect, dehydration, or cardiac ischemia. Maintain a low threshold to obtain objective monitoring and escalate.

Pediatric/geriatric considerations if applicable

Pediatric and geriatric considerations include atypical vitals, communication barriers, caregiver collateral, fall risk, polypharmacy, and frailty-informed packaging and movement.

Work of breathing is a vital sign: accessory muscle use, tripod positioning, nasal flaring, and inability to speak in full sentences are escalation cues alongside pulse oximetry and mental status.

Documentation pearls

Documentation pearls include quoting patient words for chief complaint, documenting decision capacity elements when applicable, and recording serial vitals with timestamps around interventions.

Prehospital interventions should match scope, protocol, and training. When uncertain, favor interventions with favorable risk profiles, monitor response objectively, and document what changed and why.

Exam-focused review points

Exam-focused review points emphasize first actions for unstable presentations, scope-safe choices, and the rationale that registry items reward patient-centered safety over trivia.

Scene safety and crew protection come first: stabilize hazards, establish a warm zone when possible, and keep communication channels clear so treatments are not performed in avoidable danger.
