Scene Safety and BSI

Definition

First priority at every EMS call: hazard assessment and appropriate PPE before patient contact.

Professional Standards

Professional standards for scene safety and bsi are established by the relevant certification body and regulatory agencies. Certified professionals must demonstrate competency through examination and maintain credentials through continuing education. Scope of practice is defined by state law and facility policy. Never perform tasks outside your authorized scope.

Related Procedures

Procedures related to scene safety and bsi in the EMS setting:

Pediatric weight-based dosing: Broselow tape for length-based weight estimation in emergencies
RSI sequence: preoxygenation then sedation (etomidate 0.3mg/kg or ketamine 2mg/kg) then paralytic (succinylcholine 1.5mg/kg or rocuronium 1mg/kg) then intubation then confirm placement with waveform capnography

Key Values & Ranges

Key values and ranges relevant to scene safety and bsi in prehospital care:

Parameter	Adult	Pediatric
GCS	15 is normal, under 8 = severe TBI	modified pediatric GCS for preverbal
ETCO2	35-45 mmHg	35-45 mmHg
blood glucose	70-140 mg/dL	60-100 mg/dL (neonates lower)
respiratory rate	12-20 breaths/min	25-50 (infant), 15-30 (child)

Assessment Techniques

Assessment techniques for scene safety and bsi:

APGAR: Components: Appearance, Pulse, Grimace, Activity, Respiration. Scoring: 0-10 at 1 and 5 minutes, under 7 needs intervention
Cincinnati Stroke Scale: Components: Facial droop, Arm drift, Speech abnormality. Scoring: Any 1 positive = 72% probability of stroke

Why It Matters

First step of every NREMT scenario. Failure to verbalize = automatic failure on practicals.
