Three stages of life
• You believe in Santa Claus
• You don’t believe in Santa Claus
• You are Santa Claus

Great truths about growing old• Wrinkles don’t hurt• Growing old is mandatory; growing
up is optional• When you fall down, you wonder
what else you can do while you’re down there…
• You know all the answers, but nobody bothers to ask the questions.
4
ELDERS ARE WELL ABLE TO APPRECIATE WHAT IT MEANS TO LIVE IN
THE PRESENT….. WHAT THEY HAVE TODAY IS
ALL THEY HAVE.
5
MAKING THE MOST OF TODAY IS AN ART WE SHOULD ALL CULTIVATE - AND AN OLD
PERSON IS COMPELLED TO CULTIVATE.
7
Geriatrics• Ageism• What age makes a person
geriatric?– 20 years older than me!– How old will you be in 2025?
A Look at Life in 2025Who Ages the
best?• People with
long-lived parents
• Satisfying job• Plenty of money• Married OR with
close friends
10
Statistics– Geriatric population grew by
74% between 1970 – 1999 – to almost 35 million•30% of the $800 billion health care budget
•40% of hospital bed days•1998 - @ 41% of all ambulance transports to ED’s are with elderly
•2030-Magic year. Average baby boomer turns 80 years old - 20% population 65 or older
11
• ALL OF THE RULES FOR ASSESSING AND TREATING YOUNGER PATIENTS DO NOT NECESSARILY APPLY TO ELDERS– Infections may not be accompanied by
a fever.– An abdominal catastrophe may not
cause abdominal pain– Forgetfulness may indicate a brain
tumor– Incontinence can be a sign of a heart
attack– 1/3-1/2 of elderly heart attack victims
do NOT feel crushing chest pain; primary symptoms are confusion, syncope.
13
We really do fall apart when we get old…. 1% rule
•Total body fat decreases by as much as 15-30%
•Total body water significantly decreases
•25% all suicides reported are patients over 65.
Homes are a Menace• Area Rugs• High Shelves• Stairways
without railings• Bathtubs• Sharp Counter
Corners• Still doing crazy
things
Keys• We lose reserve
as we age• Our margin of
error gets smaller and smaller
• Fluid mobilization impaired with age
17
A and P changes -General decline in organ systemsand stress response
Skin– Loss of
elasticity, collagen•Increased injury
•Dryness•Age spots
18
Eyes– Cataracts– Glaucoma
– Poor peripheral vision
– Arcus senilis– Loss of accommodation– Hyperopia– Decreased depth perception
19
Hearing– Ossicle degeneration
•Loss of high frequency hearing
– Atrophy of cochlear hair cells and auditory neurons•Decreased acuity and pitch discrimination
•Decreased sense of balance
20
Respiratory system •Vital capacity decreases 50%•Maximum breathing capacity decreases 60%
•Maximum work rate and oxygen uptake decreases 70%
•PaO2 70 torr (nl 90 torr)
•Loss of cilia, diminished cough reflex and impaired gag reflex = pulmonary diseases
CV System• Heart - less
flexible• Decreased
Cardiac Output• Less responsive
to catecholamines
• Altered electrical function
CV System• Arterioschlerosis
– Cholesterol deposits
– Vessel Narrowing
• Varicose Veins
• Medications: To compensate for CV condition
24
Renal system•30-40% decrease in number of functioning nephrons
•Renal blood flow decreases 50%– Increased risk of toxicity from all drugs and toxins
Genitourinary•Loss of bladder control
–urinary infections•Prostate enlargement
–Tumors and urinary retention
25
Nervous system– As much as 45% brain cell
loss in certain cortical areas– 6-7% reduction in brain
weight– Decreased cerebral blood
flow & increased resistance– Decreased cerebral
oxygen consumption – 15% reduction in
nerve conduction
28
Musculoskeletal system•Decrease in height of 2-3 inches due to narrowing of vertebral discs
•Posture changes - slight flexion of knee and hip joints, spine deterioration
–Kyphosis- exaggeration of the normal posterior curvature of the spine
–Spondylosis - abnormal rigidity, fixation of joint
29
•Decrease in total skeletal muscle weight
•Widening and weakening of certain bones
–Osteoporosis-softening of bone tissue due to the loss of essential minerals, esp.. calcium
31
•Endocrine System–>20% of older adults develop diabetes
–Unrecognized thyroid and parathyroid problems
33
– GI system and Metabolic
•Volume of saliva decreases 1/3;
gastric secretions diminish
•Structural changes occur
throughout GI tract
•Esophageal motility decreases
•Fecal impactions
34
Psychological/Social
– Loss of physical function
•Decreased activity
– Loss of friends/family
•Depression
– Loss of social support
•Increased isolation and anxiety
•Increased risk of suicide
attempts
35
Assessment
Complicating factors•Chief complaint may be trivial•Patient may fail to report important symptoms
•Paramedic may fail to note important symptoms
36
•Likely to suffer from more than one disease at a time
•Aging changes the patient’s response to illness or injury
•Pain may be diminished or absent
•Thermoregulatory system may be depressed
•Social and emotional factors may have greater impact on health
Complicating Factors (cont.)
37
When Assessing the Older Adult• Position yourself at eye level,
facing patient, in their visual field
• Speak slowly and distinctly• Listen to their ENTIRE answer• Use a gentle touch• Go slowly and explain
38
Communications
Diminished sight
•Increases anxiety
•Talk to patient
calmly
•Position yourself so
patient can see you
39
•Try to determine if patient’s mental status is changed
•Don’t assume confused, disoriented patient is “just senile”
•Alcoholism is more common than you think
40
•Don’t assume the patient is deaf
•Don’t shout•Write notes if necessary•Speak slowly and
directly to the patient•Whenever possible,
verify history
Diminished hearing
41
Diminished mental abilities
•Patient often confused, can’t remember details
•Noise of radio, ECG, strange voices add to confusion
•Senility and/or acute organic brain syndrome look similar; delirium, confusion, restlessness, excitement, hostility
42
• May keep patient from cooperating
• Pt. may be malnourished, dehydrated, overdosed, contemplating suicide, or imagining ailments for attention.
Depression
43
History taking - Common patient complaints
– Fatigue, weakness– Dizziness, vertigo,
syncope– Falls– H/A– Insomnia– Dysphagia– Loss of appetite– Inability to void– Constipation/
diarrhea
44
PMH - complicated, important
– Usually multiple drugs– Medication errors and
noncompliance are common– Find all drugs and record to take
to hospital with patient (try to leave)
– Try to establish old vs new drugs incl. OTC
– Try to verify Hx with reliable family/neighbors
45
– Observe surroundings for indication of pt’s ability to care for self
– Observe for evidence of drug/alcohol use
– Look for medic-alert tags, POLST form, etc
– Observe for signs of violence/abuse
PMH
47
Physical Exam In Elders
– Pt. may tire easily; Assessment usually takes longer
– Commonly wears excessive clothing
– Be aware that pt. may minimize or deny sx due to fear
– Peripheral pulses may be difficult to evaluate
48
– Must distinguish sx of chronic disease from acute problems, i.e.,•loss of skin elasticity and mouth breathing; aging vs dehydration
– Pay attention to impairments– Make eye contact– Grasp the hand - feel for
temperature, grip, skin condition
Physical Exam
49
– Address the patient by last name– Use open-ended questions– Observe for
•Behavior•Dress/grooming•Ease of rising/sitting•Fluency of speech•Involuntary movement•Nourishment
Physical Exam
50
– Breathing - adequate?– Circulation - adequate?
Irregularity? Check bilateral radial pulses, Auscultate both carotids for bruits
– BP - systolic <90 or >140 mmHg: diastolic <60 or >90 mmHg may indicate problems
– Level of consciousness
Physical Exam
51
Case study
• On a hot, humid day you are called to the neighborhood park where a 68 y/o man is c/o weakness. On arrival you see the man sitting on a park bench in shorts and a T-shirt. He is very diaphoretic and leaning with his arms and head in his lap. You discover that the patient has been playing tennis. He normally plays 2-3 hrs/day. After two sets today, he could barely run down the ball and was missing point after point.
52
• He c/o he was very dizzy and fell while playing. The patient c/o feeling generally weak. He denies any chest pain or SOB.
• PMH:– Bursitis or right shoulder– “Weak kidneys”
• Meds: OTC Advil prn• As you talk to the patient you note that
he is having trouble concentrating and you sometimes have to shout or shake him to get his attention.
53
• PE:– BP 100/60– P 130– R 26– T hot to touch– Skin, hot, diaphoretic, flushed– CBG: 126– Neuro: active, alert, oriented x 3, coherent
but lethargic, PERRL; moves all ext. spont. – note a diffuse trembling of right forearm muscles
– EKG: sinus tachycardia– BBS: =, clear
55
Trauma
• More at risk, esp. falls, assault• 100% mortality in elders with BP
<80mmHg for 15 min. or more• Slower reflexes/reaction time• Poor eyesight and hearing• Arthritis• Blood vessels less elastic
56
• Tissue and bones more fragile• More prone to head injury,
even with minor trauma• Signs of brain compression
may develop more slowly• Impaired balance and mobility
57
• Often significant spondylosis; frequent spinal injury
• Arthritic spine changes compress nerve roots
• If injury to cervical spine, cord injury more likely
• Sudden neck movement may cause cord injury; often less than usual amount of pain
• Idiopathic fractures
58
Case Study
• You are called to assess a 92 y/o woman who tripped and fell at her home. She c/o pain to her left wrist. You see a thin, elderly woman in obvious pain holding her left hand and forearm. She says that she did not see the throw rug in the hallway and tripped over it. She did not fall down because she braced herself on the wall with her left hand.
• PMH: cataracts, htn, osteoporosis• Meds: Vasotec and calcium
59
• PE:– Swollen left wrist with cyanosis;
PMS normal; no movement.– Large abrasion to elbow– Vitals:
• BP 186/106; P 112; RR 18• Cap refill normal except for left hand• Pt has poor vision on exam
– DDX?
61
Cardiovascular system
• May require higher arterial pressures for organ perfusion
• Hypovolemia and hypotension are poorly tolerated
• Response to drugs may be altered
• Syncope - increased morbidity in pt over 60
62
• MI less likely to present with classic sx
• CHF -acute and chronic• Dysrhythmias - degeneration
of conduction system• Aortic dissection
63
Respiratory system• Asthma/COPD common• Danger of alkalosis with PPV• Danger of ruptured bullae with PPV• Rib fractures common with CPR• CA• PE• Pulmonary edema• Respiratory infections
64
Renal system
• Decreased ability of kidneys to maintain normal acid-base balance
• Decreased renal function puts elder at risk for fluid overload and pulmonary edema secondary to IV therapy
65
Neurological disorders
• Coma• CVA - more common in elders; at
higher risk because of atherosclerosis, HTN, immobility, CHF, atrial fibrillation
• TIA’s common • Seizures may be mistaken for
CVA; not all major motor seizures
66
• Dizziness common complaint; common causes are alcohol and drug effects
• Senile dementia; loss of neurons begin slowly in 40’s and 50’s
• Sundowning
67
Delirium– Acute, reversible, potentially life-threatening– Abrupt disorientation for time, place– Hallucinations, illusions
Dementia – Slow, progressive loss of awareness for time, place– Unable to learn new things or remember recent
events– Long-term memory may be intact
Organic Brain Syndrome– Acute or chronic disease or injury– Causes: infection, intoxication, trauma, circulatory
disturbance, epilepsy, metabolic, endocrine diseases
68
Case History• You are called to the front yard of a
house where PD is calming a screaming elderly man. They were driving by, when they saw him running aimlessly around the street. You see the man making aimless grabbing movements in the air above his head and are barely able to understand him saying something about birds and money.
69
• Slowly you approach him and are able to get him to sit on the grass. For a few words he seems to follow what you say, then again he grabs over his head. His name is Thompson, he says, but you can’t get more than that. The people in the house have never seen the man before.
• PE– BP 192/110, P 136, RR 24, PERL– No facial droop, no focal weakness– Large abrasion on the left parietal area. You
notice tears on the knees of his pants with fresh abrasions on his knees. Rest of exam is normal.
70
• Impression?
• Is he a danger to himself?
• Is he a danger to others?
• How sudden was his deterioration?
• Tx?
72
Environmental emergencies (50-60,000/yr)• Constant high or low temps
poorly tolerated• Predisposing factors for
hypothermia;– Accidental exposure– Drugs– CNS disorders– Endocrine disorders– Low income
73
• Decreased thermoregulatory functioning
• Commonly prescribed meds inhibit sweating
• Low income
Predisposing Factors For Hyperthermia
75
Case study
• A 68-year-old woman is found unresponsive in her kitchen. You smell gas fumes from the stove. There is no sign of trauma. CBG is 120 mg/dcL.
• DDX?• TX?
76
Case study
• A man in his 70’s is found unresponsive in his apartment basement. You note empty pints of alcohol near the pt, and that the room is very cold.
• DDX?• Tx?
77
Gastrointestinal disorders
• GI bleed most common– Upper GI
•Peptic ulcers•Esophageal varices•Mallory-Weis syndrome
– Lower GI•Diverticulitis (70% of life-
threatening bleed in elders)•Tumors• Ischemic colitis
78
Pharmacology
• Elders use 25% of all prescribed and OTC drugs sold in U.S.
• Absorption, metabolism, etc. altered
• Compensatory mechanisms less effective
• Underdose, Overdose a problem; may be accidental
79
• 30% all hospital admissions related to drug-induced illness
• Common toxic drugs:– Digitalis, Antiparkinsonian drugs,
Diuretics, Anticoagulants, Lidocaine, Quinidine, Propranolol, Theophylline, Narcotics, Sedatives, Phenothiazines, Tricyclic antidepressants
80
Case study
• A 72 y/o woman is found unresponsive and apneic in her bedroom You discover an empty bottle of Placidyl in the medicine cabinet. There is no sign of trauma. CBG is 100
• DDX?• Tx:?
81
Common Atypical Presentation of Illness• Infection – frequent falls rather than fever or
↑WBCs• Acute abdomen – constipation and
↓decreased appetite rather than severe pain
• Pneumonia – vague chest pain and dry mouth rather than fever
• CHF – fatigue rather than dyspnea• MI – dyspnea and confusion rather than
fever• UTI – confusion
82
Normal Therapies That Can Be Worse Than The Problem• Lying flat• High flow oxygen• Fluid therapy• Immobilized joints• Ice packs• Medications• Multiple questioners
83
Abuse• The infliction of physical pain,
injury, debilitating mental anguish, unreasonable confinement, or willful deprivation by a caregiver of services necessary to maintain the mental and physical health of a geriatric client.
84
• S/S:– Average age 80– Pt may have chronic
diseases/disorders– Unexplained trauma is primary
finding
• Profile of potential geriatric abuser– Stressed - sleep deprivation,
marital discord, etc.– Life may be in disarray; as patient
deteriorates, abuse develops
86
Injury and Illness Prevention• Take supplements, especially
calcium and vitamin D• Increase physical activity and
exercise• Alter environment to improve safety
– Grab bars in bathroom– No throw rugs– Better lighting– Unobstructed paths
87
Prevention
• Regular vision screening• Driving cautions
– Seatbelt use– Reduce speed– Day time driving– Avoid in bad weather– Avoid left turns– Early screening
89
Summary
• Respect your patients modesty and other needs
• Explain actions clearly • Geriatric patients may minimize
or deny symptoms• Gather medication list to take
with you, but try to leave meds at home
90
Observed changes in older adults frequently represent the normal aging process. These changes may also represent a body system that is malfunctioning.

More great truths about aging• Forget the health food… you need
all the preservatives you can get.• You find time may be a great
healer, but it’s a lousy beautician.• Wisdom comes with age, but
sometimes age comes alone.
