Q

What is FEV1 and how is it measured?

What is PEFR and how is it measured?

A

Forced Expiratory Volume in 1 second- Measures amount of air you can force from your lungs in 1 second
- Measured by Spirometry Test

PEFR (Peak Expiratory Flow Rate)- Measures Maximum SPEED of expiration
-Measured by Peak Flow Meter

16
Q

What are signs that things are going bad with someone having an acute asthma episode?

What should you do?

A
  • Decreased Wheezing (less air flow)

- Call Doctor 1st for mechanical intubation

17
Q

What is Status Asthmaticus?

A

Status Asthmaticus- A severe, life threatening complication of asthma that is refractory to usual treatment
-Places the patient at risk for respiratory failure

18
Q

Signs of Status Asthamticus

A
  • Hypertension
  • Sinus Tachycardia
  • Ventricular Arrhythmias
19
Q

What should you do if a patient with status asthamticus doesn’t respond to Beta-Adrenergic Agonist?

A

IV AMINOPHYLLINE (Big Strong Drug)

20
Q

What can you give someone with asthma going through metabolic acidosis?

A

NaHCO3 (Sodium Carbonate)

21
Q

When should a patient use a long term Beta 2 Agonist?

Give one example of a Beta 2 Agonist

A

Only be used after client is using a long term inhaled corticosteroid

Salmeterol (Serevent)

22
Q

What is a common side effect of a short acting Beta2 Agonist? Why is it a side effect?

A

Tremors because it is a sympathomnetic drug

23
Q

What should you do for the following Peak Flow Results and describe these results?

Green Zone
Yellow Zone
Red Zone

A 
Green Zone (80-100% of personal best)
- Remain on medication and stick with plan
Yellow Zone (50-80% of personal best)
-Use short acting Beta 2 Agonist (ex. Proventil)
Red Zone (50-80% of personal best)
-Use short acting Beta 2 Agonist (ex. Albuterol) and CONTACT HCP
24
Q

What medication interaction should the patient know if they are treating their asthma?

A

Beta Blockers (ex. proanolol) can cause bronchospasm in the patients with asthma

25
Q

How do you use an inhaler?

A
  1. Shake inhaler
  2. Breathe out all the way
  3. Hold your inhaler the way your doctor prescribed and as you breath in slowly through your mouth press down on the inhaler one time
  4. Keep breathing in slowly as deeply as you can
  5. Hold your breath as you count to 10 slowly
  6. If using Beta 2 Agonists, wait 1 minute between each puff but only for these meds
26
Q

What is emphysema?

A

Alveoli are damaged and over time, the inner walls of the alveoli weaken and rupture, creating larger air spaces instead of small ones

27
Q

What is COPD?

What is the criteria for someone to be diagnosed with COPD?

A

Chronic airway obstruction resulting from chronic bronchitis and emphysema

-EXCESSIVE BRONCHIAL MUCUS with cough for at least 3 months during two successive years

28
Q

What are some manifestations of COPD?

A
  • Decreased compliance/elasticity
  • Decreased expansion
  • Increased Dead Air (Residual Volume)
29
Q

How does a person with COPD compensate?

What happens to the lung tissues of COPD?

A
  • Increased Respiratory Rate
  • Breathes Harder
  • Surface Area Decreases
  • Disappearance of Cilia
  • Narrowing of Small Airways
30
Q

What is the difference bewteen Chronic Bronchitis and Emphysema?

A

-Alveolar Structure and Capillaries are Normal in Chronic Bronchitis

31
Q

What are some complications that can occur with COPD?

A
  • Peptic Ulcer
  • GERD
  • Pneumonia
32
Q

What should you do in terms of O2 therapy for someone with COPD?

A

Usually 2-3 Liters of O2 unless otherwise ordered until O2 SATs are > 90%

33
Q

What is Chest PT (Physiotherapy)?

A

Combines the Positioning of Postural Drainage with the Action of Percussion which Loosens Secretions

34
Q

What are the steps for Chest PT (Physiotherapy)?

A
  1. Bronchodilateor to Open up Passages
  2. Cough up Loosen Secretions to mobilize them
  3. Remain in each postural position for a minimum of 5 minutes to get secretions up
35
Q

What are some exercises a person with COPD can do to?

A

Pursed Lip Breathing- Inhale slowly through the nose, relax cheeks, and blows air out the mouth

Abdominal Breathing- Uses abdominal muscles to assist in Expiration; Lie down and place paperback book on their upper abdomen and halve abdominal muscles contract during Expiration

36
Q

What are some symptoms of Cystic Fibrosis?

A
  • Increasingly Recurring Lung Infections

- Productive Green Mucus Cough
