Q

How does a slow progression of dyspnea differ from a rapid progression?

A
  • Slow progression = likely to lead to a chronic etiology
  • Rapid = likely to lead to an acute etiology and/or likely to coincide w/ alarm symptoms that may need immediate intervention

  2. Hx MI
  3. Hx CAD
  4. Meds –> especially new meds that were started around the time of onset
  5. Smoking history … hx of COPD, CAD, Lung CA
  6. Occupation …. was there occupational exposure?
  7. Prolonged immobilization
  8. Hx of CA
  9. OCP/ Estrogen Use
  10. Surgery
  11. Recent Travel
18
Q

What are the 5 Risk Factors for DVT/PE?

Study These Flashcards
A
  1. Prolonged Immobilization
  2. Hx of CA
  3. OCP/ Estrogen Use
  4. Surgery
  5. Recent travel
19
Q

What are the 6 Alarm Symptoms for Dyspnea?

Study These Flashcards
A
  1. Chest pain (pleuritic vs. Cardiac)
  2. Lip swelling, hives AND wheezing
  3. Pink frothy sputum
  4. Fever w/ sputum production
  5. Fever w/ worsening sore throat and hoarse voice
  6. Awakens from a sleep
20
Q

What does ALARM SYMPTOM CHEST PAIN indicate?

Study These Flashcards
A
  1. Pleuritic –> sharp, unilateral chest pain that increases with respiration….

serious causes = Pulmonary embolism, PTX, pneumonia

  1. Cardiac –> MI
21
Q

What does ALARM SYMPTOM “LIP SWELLING, HIVES AND WHEEZING” indicate?

Study These Flashcards
A

Anaphylaxis, angioedema

22
Q

What does ALARM SYMPTOM “PINK FROTHY SPUTUM” indicate?

Study These Flashcards
A

Flash Pulmonary Edema

23
Q

What does ALARM SYMPTOM FEVER W/ SPUTUM PRODUCTION indicate?

Study These Flashcards
A

Pneumonia vs. bronchitis…

Pneumonia = bacterial

Most of Bronchitis = VIRAL…AKA NO ANTIBIOTICS!!

24
Q

What does ALARM SYMPTOM “FEVER W/ WORSENING SORE THROAT AND HOARSE VOICE” indicate?

25
Why does dyspnea occur?
The purpose of breathing is to meet the metabolic demands of the body...
26
What are the FOUR major physiologic reasons dyspnea results from?
1. Any condition that increases the work of breathing ... CANT GET THE AIR IN! 2. POOR oxygen uptake 3. Any condition that increases respiratory drive 4. Exacerbation of primary psychological conditions
27
1. Any condition that increases the work of breathing... CAN GET THE AIR IN!
1. Airway obstruction Changing in lung compliance Respiratory muscle weakness THINK OF ANATOMY... a) Upper airway --> epiglottis, foreign body b) Bronchi --> asthma, acute bronchitis c) Alveoli --> Emphysema, Interstitial lung disease d) External compression --> PTX e) Thoracic wall --> scoliosis
28
2. Poor oxygen uptake
LUNG CIRCULATION PROBLEM a) Pulmonary Embolism b) Left sided Heart Failure c) Pulmonary Hypertension HEMOGLOBIN DISORDER a) Anemia b) Carbon monoxide poisoning
29
3. Any condition that increases respiratory drive
Hypoxia, metabolic acidosis REMEMBER.... metabolic acidosis is a surplus of positive cations (hydrogen)... the way the body compensates for a metabolic acidosis is to increase the respiration rate... WHY? in the respiratory system, CO2 is an ACID... to decrease CO2, you need to increase the respiratory rate... which results in DYSPNEA
30
4. Exacerbation of primary psychological conditions
Anxiety BE CAREFUL!!!!!!!! MANY PATIENTS who have organic causes for their dyspnea will appear to be anxious.
31
What can manifest as ANXIETY?
HYPOXIA!!!!
32
Whats the FIRST THING TO DO when categorizing dyspnea?
Determine if its ACUTE OR CHRONIC! Will help us determine what type of questions will be most important.
33
What is the duration of acute dyspnea?
34
What are the FOUR physical signs of ACUTE dyspnea?
1. Can only say 2-3 words w/o stopping to take a breath 2. Nasal flaring 3. Cyanosis 4. ACCESSORY MUSCLE USE: chest wall retractions, abdominal muscle use, neck muscle use (particularly the sternocleidomastoid and scalene muscles)
35
What are the CAUSES of ACUTE dyspnea? (8)
PPOPPA-MM 1. Pulmonary Embolism 2. Pulmonary Edema a) Pulmonary (less common than cardiogenic): high altitude, gas inhalation b) Cardiogenic : CHF 3. Obstructed Airway a) Foreign body b) Epiglottis 4. Pneumothorax (spontaneous) 5. Pneumonia/Bronchitis 6. Asthma or COPD 7. MI/tamponade 8. Medications
36
What is the duration of chronic dyspnea?
> 1 Month
37
What will the majority of people w/ chronic dyspnea of unclear etiology end up having? (5)
``` COPD Asthma Interstitial Lung Disease Myocardial Dysfunction Obesity/Deconditioning ```
38
What are the CARDIOVASCULAR causes of CHRONIC DYSPNEA? (4)
Muscle : cardiomyopathies Vessels : Ischemia Valves : Regurgitation, stenosis, or infection Pericardium : Effusion, inflammation
39
What are the PULMONARY causes of CHRONIC DYSPNEA? (6)
Bronchi : Mass, Foreign Body Bronchioles : Asthma, chronic bronchitis Interstitial Lung Disease Alveoli : Emphysema, Chronic Pneumonia Pleura : Effusions Lung Cancer
40
What are the "OTHER" causes of CHRONIC DYSPNEA? (5)
Anemia Chest wall abnormalities : Scoliosis, Pectus Excavatum (sternum and chest wall appear to be sunken in) Deconditioning Acidosis Neurmomuscular Disease (either an issue w/ ACTUAL MUSCLES DOING THE WORK of breathing... OR issue w/ the CONTROL of respirations in the CNS)
