Geriatrics
Objectives
• Discuss statistics relating to the
geriatric imperative.
• Discuss pathophysiologic changes that
occur to the body due to aging.
• Integrate assessment findings with
related pathophysiology.
• Review current treatment strategies for
geriatric patients.
Introduction
• People over the age of 65 make up the
fastest-growing segment of the
population.
• Changes in physiology due to aging
have an effect on pathophysiology as
compared to younger adults.
Introduction (cont’d)
• Geriatric patients typically have more
than one disease and take more than
one medication.
Epidemiology
• Almost 40 million in 2008, or 12.8 of
the population.
• Cardiovascular disease is the leading
cause of death, followed by cancer,
strokes, and COPD.
• They use ⅓ of all prescriptions.
• The average geriatric patient takes 4.5
medications per day.
Pathophysiology
• Human body changes with age:
cellular, organ, and system functions.
• Changes in normal physiology start
around age 30.
• Process can be slowed with diet and
exercise, but it cannot be stopped
entirely.
Pathophysiology (cont’d)
• Cardiovascular system
– Degenerative process to the
myocardium
– Damage to valves
– Thickening of the walls
– Loss of artery elasticity
– Decrease in baroreceptor activity
Pathophysiology (cont’d)
• Respiratory system
– Size and strength of respiratory muscles
decrease.
– Alveolar surfaces degrade, impairing
gas exchange.
– Chemoreceptors begin to fail.
– More turbulent airflow through the
bronchioles.
Pathophysiology (cont’d)
• Nervous system
– Nerve cells degenerate and die as early
as in the mid-20s.
– Reflexes slow, proprioception falters.
– Brain atrophies with a resultant increase
in CSF.
– Regulation of basal bodily functions
becomes less sensitive.
Pathophysiology (cont’d)
• Gastrointestinal system
– Sense of taste and smell is diminished.
– Cardiac sphincter becomes weaker.
– Hepatic function decreases.
– Lining of GI system degenerates,
resulting in lesser absorption of
nutrients.
Pathophysiology (cont’d)
• Endocrine system
– Hormones that elevate blood pressure
and those that regulate fluid balance
become deranged.
– Stimulation of adrenergic sites
diminishes due to failure of sensitivity of
receptor cells.
Pathophysiology (cont’d)
• Musculoskeletal system
– Loss of minerals from the bones.
– Vertebral disks narrow.
– Joints lose flexibility.
– Synovial fluid thickens.
Pathophysiology (cont’d)
• Renal system
– Decrease in nephrons, kidneys shrink
– Diminished ability to filter blood
– Fluid and electrolyte disturbances
Pathophysiology (cont’d)
• Integumentary system
– Skin becomes thinner from a loss of
subcutaneous layer.
– Replacement cells generate more
slowly.
– Sense of touch is dulled, less
perspiration.
– Less effectiveness as an external
barrier.
Changes in the body systems of the elderly.

Emergency Medical Care
• Manual cervical spine considerations
• Assess and maintain the airway.
• Determine breathing adequacy.
– High-flow via NRB with adequate
breathing.
– High-flow via PPV @ 10-12/min if
inadequate.
– Maintain saturation >95%.
Emergency Medical Care (cont’d)
• Assess circulatory components.
– Check pulse, skin characteristics.
– Control major bleeds.
Emergency Medical Care (cont’d)
• Initiate transport with Paramedic
intercept.
• Position the patient:
– Sitting up if able to maintain own
airway.
– Lateral recumbent with altered
mentation.
– Supine if immobilized.
Emergency Medical Care (cont’d)
• Constantly monitor airway, breathing,
and circulation.
• Mental status changes are key to
determining improvement or
deterioration.
Case Study
• Your EMS unit is dispatched for a
“possible cardiac arrest” in the lowincome housing district. Upon arrival,
police escort you into a single-bedroom
dwelling where an unresponsive elderly
male is found in bed. The report is that
the neighbor hasn't seen him in a few
days so he asked the building manager
to gain access.
Case Study (cont’d)
• Scene Size-Up
– Standard precautions taken.
– Scene is safe, no entry or egress
problems.
– 70–75-year-old male, about 200
pounds.
Case Study (cont’d)
• Scene Size-Up
– Patient dressed in pajamas, time is
1430 hrs.
– NOI is unknown/unresponsive, possible
arrest.
– Friend is on scene, but is not much help
regarding history.
Case Study (cont’d)
• Describe possible ways to learn of the
patient's medical history.
• For each body system, name at least
one differential that could cause
unresponsiveness.
– Nervous
– Respiratory
– Cardiac
– Endocrine
Case Study (cont’d)
• Primary Assessment Findings
– Patient unresponsive.
– Pupils reactive, membranes dry, tongue
furrowed.
– Some vomitus in airway, gurgling with
breathing.
Case Study (cont’d)
• Primary Assessment Findings
(continued)
– Respirations rapid and deep.
– Carotid pulse 120/min, peripheral pulse
absent.
– Peripheral skin warm and dry.
Case Study (cont’d)
• How would you prioritize this patient?
• What are the patient's life threats, if
any?
• What care should be administered
immediately?
Case Study (cont’d)
• Medical History
– Unknown
• Medications
– Glucophage found in bathroom
• Allergies
– Unknown
Case Study (cont’d)
• Pertinent Secondary Assessment
Findings
– Pupils reactive to light, membranes dry.
– Airway patent, patient breathing fast
and deep.
– Central pulse present, peripheral
absent.
– Skin is dry, delayed capillary refill.
Case Study (cont’d)
• Pertinent Secondary Assessment
Findings (continued)
– No bruising, guarding or rigidity to
abdomen.
– BGL 710mg/dL, SpO2 96% on high flow.
– B/P 82/62, HR 112, RR 28 and deep.
– No other findings contributory to this
report.
Case Study (cont’d)
• Is this a structural or metabolic cause
of unresponsiveness?
• What is the likely underlying cause for
the emergency?
• Explain the pathology for the following:
– Unresponsiveness
– Rapid heart rate, dehydration findings
Case Study (cont’d)
• Care provided:
– Patient immobilized as a precaution.
– High-flow oxygen via NRB mask.
– Patient loaded on wheeled cot and taken
to ambulance.
– Initiated intravenous access.
– Emergent transport to the hospital.
Summary
• Geriatric patients, like pediatric
patients, have an altered physiology
that needs to be considered given
illness and injuries.
• The normal decline in the body systems
renders them susceptible to a multitude
of emergencies.
Summary (cont’d)
• Carefully manage and closely watch
elderly patients, as they may
deteriorate suddenly.
