Overview¶

Patients with developmental disabilities, physical disabilities, or technology-dependent medical needs require adapted assessment and communication strategies. EMT-B encounters patients with autism spectrum disorder, Down syndrome, cerebral palsy, tracheostomies, feeding tubes, and other special needs. The emergency may involve the underlying condition, a complication of their assistive technology, or an unrelated medical problem. Understanding baseline function and building trust with caregivers are essential.

Key Points¶

Caregiver is your best resource — always involve them; they know the patient's baseline and what "different" looks like
Communication first — never assume cognitive deficit based on physical presentation; adapt your approach before assuming inability to communicate
Do not separate patient from familiar caregiver unless absolutely necessary — separation increases distress and can trigger behavioral escalation
Technology-dependent patients: assess the device first — trach obstruction, G-tube dislodgement, or vent failure may be the emergency
Behavioral crisis vs. medical emergency — always rule out medical cause first; agitation, self-harm, or behavioral change in a known patient may signal pain, infection, constipation, or other medical problem

Autism Spectrum Disorder (ASD)¶

ASD is a neurodevelopmental condition affecting social communication and behavior. Prevalence ~1 in 36 children (2023 CDC data). EMT encounters include behavioral crisis, injury from self-stimulation or self-harm, and unrelated medical emergencies.

Key characteristics affecting EMS response: - Sensory sensitivities: lights, sirens, touch, and noise can be intensely distressing — reduce stimulation aggressively - Communication variation: some patients are nonverbal; others have scripted or atypical speech; do not interpret silence as understanding - Routine disruption: EMS contact is inherently disruptive — predictability helps; explain every step before doing it - Eye contact: lack of eye contact is normal, not a sign of altered LOC or disrespect - Self-stimulating behaviors (rocking, hand-flapping): do not attempt to stop unless directly causing injury

EMT-B approach: 1. Reduce stimulation — turn off sirens, dim lights if possible, minimize personnel in patient's space 2. Speak calmly, simply, and literally — avoid idioms ("I'm just going to take a quick look") that may be interpreted concretely 3. Involve caregiver — they may serve as communication intermediary and provide critical baseline 4. Allow familiar object — stuffed animal, weighted blanket, or device if patient uses one for self-regulation 5. Approach slowly, telegraph movements — sudden approaches trigger startle and distress 6. Do not interpret behavioral escalation as aggression — it is almost always a distress response

KEY DIFFERENTIATOR — ASD Behavioral Crisis vs. Medical Emergency: A patient with known ASD who is unusually agitated, self-injurious, or inconsolable may have a medical cause — pain, UTI, constipation, headache. Patients with ASD often cannot verbalize pain and express it behaviorally. Rule out medical cause first.

Down Syndrome¶

Down syndrome (Trisomy 21) is the most common chromosomal condition, with a characteristic phenotype and associated medical comorbidities that affect EMS response.

Key medical associations: - Atlantoaxial instability (~15%): C1-C2 joint is unstable — excessive cervical manipulation can cause spinal cord injury; use caution with any cervical movement, especially during airway management - Congenital heart disease (~50%): many have repaired or unrepaired CHDs; cardiac emergencies may present differently - Hypothyroidism: common; may present as cold intolerance, bradycardia, fatigue - Respiratory infections: higher susceptibility; pneumonia and RSV are common emergencies - Obesity: increases anesthesia and airway management difficulty - Leukemia risk: higher than general population; easy bruising may not be from trauma

Communication adaptations: - Most patients with Down syndrome have some verbal communication ability; cognitive disability is variable - Speak directly to the patient as well as the caregiver - Use simple, concrete language; avoid complex multi-step instructions - Allow more time for response — processing time is longer

KEY DIFFERENTIATOR — Atlantoaxial Instability: When managing an airway in a patient with Down syndrome, use gentle, controlled cervical positioning. Do NOT apply aggressive extension or traction. This is a documented EMS risk specific to this population.

Cerebral Palsy (CP)¶

CP is a group of permanent movement and posture disorders from non-progressive brain injury occurring before, during, or shortly after birth. Presentation ranges from mild gait disturbance to complete dependence.

Key characteristics: - Spasticity: increased muscle tone — limbs may be rigid and resist standard assessment positioning - Contractures: joints fixed in abnormal positions — do not force; splint in position found - Communication: many CP patients have intact cognition but limited or no verbal communication; augmentative devices (AAC), eye gaze, or picture boards may be used - Seizures: very common comorbidity — up to 50% have epilepsy - Dysphagia: swallowing difficulty; aspiration risk; may have G-tube - Respiratory compromise: common from aspiration, recurrent pneumonia, or scoliosis

EMT-B approach: - Do not assume cognitive deficit because of physical appearance or non-standard communication - Assess baseline from caregiver — what is their normal tone, movement, posture? - Position of comfort for transport — may differ from standard supine; work with caregiver - Seizure management per standard protocol

Tracheostomy Patients¶

A tracheostomy (trach) is a surgical airway through the anterior neck into the trachea. Patients may be technology-dependent (ventilator) or breathe spontaneously through the trach.

Common trach emergencies:

Problem	Signs	EMT-B Action
Obstruction (mucus plug)	Respiratory distress, stridor, desaturation, inability to ventilate through trach	Suction the trach; attempt BVM ventilation through trach; if unresolved — plug may be in inner cannula: remove and replace inner cannula or replace entire tube
Dislodgement / decannulation	Tube visibly displaced or out; air leak around site	Replace tube if within scope and caregiver trained; if unable — attempt bag-mask over both mouth AND nose with trach covered; emergency transport
Infection / stoma site	Redness, purulence, swelling at stoma	Document; transport; not immediately life-threatening unless extending to airway

Suction procedure (basic): 1. Maintain sterile/clean technique — gloves minimum; sterile gloves preferred 2. Pre-oxygenate if possible 3. Insert suction catheter without suction applied — advance until resistance; withdraw slightly 4. Apply suction while withdrawing in rotating motion — no more than 10–15 seconds 5. Re-oxygenate; repeat if needed

BVM via tracheostomy: - Attach BVM directly to trach hub (15mm adapter) - Seal mouth and nose if trach is fenestrated (fenestrated trachs have a hole — air will escape upward) - Watch for chest rise; confirm with SpO₂

KEY DIFFERENTIATOR — New vs. Mature Tracheostomy: A trach less than ~1 week old is a surgical wound — the tract has not fully matured. Do NOT attempt to replace a dislodged new trach — the tract can close rapidly. Cover the stoma, ventilate via mouth/nose, and transport immediately.

Gastrostomy Tube (G-Tube) Patients¶

A G-tube is a feeding tube placed directly into the stomach through the abdominal wall. Used for patients who cannot safely swallow.

Common emergencies: - Dislodgement: tube out of site — stoma can begin closing within hours; note time, transport, inform hospital; caregiver may have spare tube - Obstruction: inability to use tube for feedings or medications - Leakage / skin breakdown around site - Aspiration: G-tube patients have high aspiration risk even with tube in place — head of bed elevation and positioning matter

EMT-B actions: Document tube status (in/out, intact, leaking), time of dislodgement if applicable, transport to ED for replacement.

Spina Bifida¶

Spina bifida is a neural tube defect where vertebrae and/or meninges fail to close during fetal development, leaving spinal cord tissue exposed.

Key EMT-B facts: - LATEX ALLERGY — extremely high prevalence in spina bifida patients; always use non-latex gloves and avoid latex equipment entirely; ask before use of any latex device - Varying degrees of paralysis below the level of defect; bladder/bowel dysfunction - Exposed neural tissue (if visible): cover with moist sterile dressing, maintain warmth - Resuscitate as needed; transport

KEY DIFFERENTIATOR — Spina Bifida and Latex: Spina bifida has the highest latex allergy prevalence of any patient population. This is specifically tested. Always switch to non-latex before contact and ask about latex allergy before any procedure.

LVAD (Left Ventricular Assist Device)¶

An LVAD is a mechanical pump surgically implanted to assist a failing left ventricle. It produces continuous, non-pulsatile flow — the patient may have no palpable pulse even when the device is functioning normally.

Signs of LVAD patient: - Wearing vest/harness with battery pack and controller - No palpable pulse — this is NORMAL for a functioning LVAD - MAP (mean arterial pressure) measured by Doppler only — standard BP cuff may not work - Audible humming sound over the chest — device is working

EMT-B management: - Do NOT start standard CPR — compressions can damage the device; local protocols vary (some allow manual CPR if device has failed and patient is unresponsive) - Contact LVAD coordinator or destination hospital immediately - If device alarm sounding: connect to AC power (battery may be depleted) - Transport to an LVAD center

If sudden deterioration — DOPE mnemonic: | Letter | Problem | |---|---| | D | Displacement (device dislodged or position changed) | | O | Obstruction (kink in driveline, clot) | | P | Pneumothorax (tension) | | E | Equipment failure (battery, controller malfunction) |

KEY DIFFERENTIATOR — LVAD and CPR: No pulse = NORMAL for LVAD. Standard CPR is contraindicated unless device has failed and patient is unresponsive AND local protocol authorizes it. The humming sound IS the device working. Silence = device failure = emergency. Contact LVAD coordinator immediately.

Communication Adaptations — General Principles¶

Situation	Adaptation
Hearing impairment	Face patient; speak clearly; write if needed; sign if trained; hearing aids in and working?
Visual impairment	Verbal description of all actions before touching; identify yourself; consistent voice orientation
Nonverbal / AAC user	Allow access to their device; yes/no questions; caregiver as communication bridge
Cognitive disability	Simple concrete language; one instruction at a time; verify understanding; avoid idioms
Behavioral distress	Reduce stimulation; maintain calm; involve caregiver; do not restrain unless safety requires

NREMT Relevance¶

ASD: reduce stimulation, involve caregiver, rule out medical cause for behavioral escalation
Down syndrome: atlantoaxial instability — gentle cervical handling during airway management
Trach obstruction: suction first; if fails, check/replace inner cannula; BVM via trach hub; DOPE (Displacement/Obstruction/Pneumothorax/Equipment failure) for sudden deterioration
New trach (<1 week): do NOT replace dislodged tube — close stoma, ventilate via mouth/nose, transport
Spina bifida: latex allergy — always use non-latex gloves and equipment
LVAD: no pulse = NORMAL; do NOT start standard CPR; humming sound = device working; silence = emergency; contact LVAD coordinator immediately
Caregiver is the expert on baseline — always ask "what is different today?"
Never assume cognitive deficit based on physical disability or non-standard communication

geriatric — elderly patients with dementia, cognitive changes, and baseline variation
seizure — seizures are common in CP and Down syndrome populations
primary-assessment — communication adaptations begin at initial contact
communicable-diseases — trach patients have increased respiratory infection risk
