IntroductionIntroduction
• In 1996, asthma was the leading cause of hospitalizations in New York City for children (up to the age of 14 ).
• In 1995, asthma hospitalizations for children of the same age group were 3 times the national average and 5 times the state average.
• In 1996, asthma was the leading cause of hospitalizations in New York City for children (up to the age of 14 ).
• In 1995, asthma hospitalizations for children of the same age group were 3 times the national average and 5 times the state average.

Introduction (cont.)Introduction (cont.)
• In New York City, EMTs & Paramedics treat approximately 50,000 asthmatics each year.
• While these patients benefit from bronchodilator therapy, the availability of ALS response units cannot always be assured.
• As a result, these patients are treated by EMTs.
3
Mortality from asthma is increasing worldwide
From 1980 - 1987, the death rate From 1980 - 1987, the death rate has increased by 31% in the United has increased by 31% in the United
States. 5,000 deaths per year.States. 5,000 deaths per year.
4
Many studies have shown
The efficacy and SAFETY of albuterol in the treatment of bronchospasm associated with asthma.
5
An expanded scope of practice for EMTs
Could provide benefits to the population of asthmatics in New
York City
6
May 1, 1998 - 2 new call types were implemented
• ASTHMP - for patients under 15 years old
• ASTHMA - for patients 15 years of age or older
7
Inclusion CriteriaInclusion Criteria
• Patients between the ages of 1 and 65 years old (with no ALS immediately available).
• Patients complaining of difficulty breathing secondary to an exacerbation of their previously diagnosed asthma.
8
Exclusion CriteriaExclusion Criteria
• Patients with a history of hypersensitivity to albuterol sulfate.
• Patients exhibiting signs of respiratory failure (a patient requiring ventilations).
9
Adult Respiratory Failure
• Decreased level of consciousness
• Too dyspneic to speak
• Cyanosis (despite oxygen therapy)
• Diminished breath sounds
• Patient requires assisted ventilations
10
Pediatric Respiratory Failure
• Ineffective respiratory effort with central cyanosis, agitation or lethargy, severe dyspnea or labored breathing, bobbing or grunting and marked intercostal & parasternal retractions.
11
Differential Diagnosis of Bronchospasm
• COPD
• Foreign body obstruction
• Pulmonary Embolus
• Anaphylactic reaction
• Pulmonary Edema
• Asthma
12
Pathology of Asthma
• Reversible smooth muscle spasm of the airway associated with hypersensitivity of the airway to different stimuli. Primarily an inflammatory process.
• Smooth muscle contractions
• Mucosal edema
• Mucous plugging
13
The Lungs
14
The Lower Airway
15
Triggers of Asthma Attacks
• Allergies
• Infection
• Stress
• Temperature changes
• Seasonal changes
16
Signs and Symptoms
• Dyspnea• Wheezing• Tachypnea• Tachycardia• Cyanosis• Cough
• Accessory muscle use• Inability to speak…..
in complete… sentences.• Anxiety (hypoxia)• Prolonged expiratory phase• Tripod positioning• Nasal Flaring (infants)
17
Respiratory Muscle Fatigue
• Muscles are overworked to compensate for problem.
• Increased work of breathing
• Can lead to exhaustion and respiratory failure.
18
Assessment of The Asthma Patient
19
Assessment of the Asthmatic
• Chief complaint
• History of present illness
• Past medical history
20
History of Present Illness
• How long
• Events leading up to…
• How severe (Borg Scale)
• Aggravating / Alleviating factors
• Other complaints
• Steroid use in last 24 hours (p.o. / inhaled)
• Other medications
21
Past Medical History
• Confirm asthma history
• Other medical conditions (cardiac)
• E.D. visits for asthma in the last 12 months
• Hospital admissions for asthma in last 12 months
• Previously intubated due to asthma?
• Allergies to medications, etc.
22
Note: Do not delay treatment to solicit a patient’s medical history
(except: asthma,allergies and cardiac history.)
23
Physical Examination
• Respiratory distress vs. Respiratory failure
• Posturing (tripod positioning)
• Pursed lip breathing
• Vital signs
• Skin color, temperature and moisture
• Ability to speak... in complete... sentences
• Accessory muscle use
24
Physical Examination (cont.)
• Borg Scale (0 - 10)
• Peak flow
• Height (you may ask patient)
25
26
Peak Flow Meter
27
Auscultation of Breath Sounds
• General requirements for successful evaluation:
• Patience
• Effective technique
• Good hearing
• Knowledge of sounds
28
Physical Examination (cont.)
• Assessing lung sounds• Rales
• Rhonchi
• Stridor
• Wheezing
29
Lung Sounds Found In Common Emergency Conditions
• C.O.P.D.– Diminished– Wheezes– Prolonged expiratory phase
• Pneumonia– Rales (usually in one area)
30
Lung Sounds Found In Common Emergency Conditions
• Pulmonary Edema– Diminished Sounds– Rales (usually bilateral)
• Asthma– Diminished Sounds (may be on one side)– Wheezes– Prolonged expiratory phase
31
Wheezes
• High pitched, continuous sounds
• Occur on inspiration or expiration
• Result of narrowed bronchioles
32
Wheezing Assessment
• No Wheezing
• Wheezing (audible with stethoscope)
• Wheezing (audible without scope)
• Poor air exchange (diminished lung sounds)
33
Absent or Diminished Sounds
• Pneumothorax
• Hemothorax
• Obesity
• Hypoventilation
• Fluid or pus in pleura or lung
• COPD or Asthma with poor airflow
34
Stethoscope Placement
35
Technique
• Sit patient up
• May not be possible to auscultate all areas
• Place diaphragm firmly on chest wall
• Avoid extraneous noise
• Avoid prolonged examination of the chest
36
Technique
• Have the patient open mouth and take deep breaths.
• Avoid hyperventilation.
• Listen at each location and note abnormalities.
37
