Definition

Legal doctrine allowing treatment of unconscious patients based on assumed consent to life-saving care.

Exam Focus Areas

On the Nremt Emt, Nremt Paramedic, Cna Nnaap, Medical Assistant exam(s), questions about implied consent typically test:

Correct medication selection, dosing, and route of administration
Recognition of signs and symptoms requiring immediate intervention
Assessment findings that differentiate between similar presentations

Equipment & Tools

Equipment used in implied consent assessment and treatment:

BVM: Bag-valve-mask for manual ventilation. Available sizes: Adult (1500mL), Pediatric (500mL), Infant (250mL)
King airway: Supraglottic blind-insertion airway device. Available sizes: Size 3 (4-5 ft), Size 4 (5-6 ft), Size 5 (over 6 ft)
Waveform capnograph: Measures end-tidal CO2 continuously with waveform display. Available sizes: Mainstream (inline), Sidestream (sampling)

Troubleshooting

Troubleshooting implied consent in the field:

Waveform capnograph: If measures end-tidal co2 continuously with waveform display fails, verify connections, check battery, try alternate equipment. Available sizes: Mainstream (inline), Sidestream (sampling)
BVM: If bag-valve-mask for manual ventilation fails, verify connections, check battery, try alternate equipment. Available sizes: Adult (1500mL), Pediatric (500mL), Infant (250mL)
IO drill: If intraosseous access device for emergent vascular access fails, verify connections, check battery, try alternate equipment. Available sizes: EZ-IO: 15mm (peds), 25mm (adult), 45mm (obese)

Calculation Methods

Dosage calculations related to implied consent in EMS:

nitroglycerin: 0.4mg SL q5min x3 doses (SL)
naloxone: 0.4-2mg IV/IM/IN, titrate to respirations (IV, IM, IN)
adenosine: 6mg rapid IV push, then 12mg if needed (IV rapid push with flush)

Pediatric dosing: always calculate by weight (mg/kg). Use Broselow tape if weight is unknown.

Why It Matters

What equipment is needed for managing implied consent in the field?▼

For implied consent: King airway provides Supraglottic blind-insertion airway device. AED provides Automated external defibrillator for VF/pVT. Waveform capnograph provides Measures end-tidal CO2 continuously with waveform display.
