Respiratory therapies (Asthma, COPD, etc) workbook words

Question 1

what is the difference between Spirometry & Peak Expiratory Flow (PEF)?

2 points (4 things) for PEF

2.5 points (5 things) for Spirometry
+ 1.5 (3) notes for Spirometry

Answer 1

Spirometry & Peak Expiratory Flow (PEF):

• measures MAX SPEED of expired air
• used to confirm diagnosis
• used to identify triggers
• used to monitor effectiveness of medication

Spirometry:

• is the goal standard LUNG FUNCTION TEST
• used to diagnose asthma
• used to evaluate effectiveness of treatment
• used to distinguish b/w Obstructive vs Restrictive
• provides; FEV1 & FVC
• note: FEV1/FVC –>determines obstructive
• note: FVC / predicted FVC –> <80% = restrictive
• note: spirometry measurements depends on predicted normal values such as;
• age
• height
• gender
• ethnicity

Question 2

what do you do to determine if the Airflow restriction is reversible?

Answer 2

what do you do to determine if the Airflow restriction is reversible?

Answer:
repeat test 10-15 mins post-delivery of 4 puff salbutamol (100mcg/actuation)

(note: used pressurised Metered Dose Inhaler [MDI] with spacer)

if FEV1 increase by 12% or 200mL –>airflow limitation is reversible

Question 3

what are the 3 categories of inhaled respiratory therapy devices?

Answer 3

what are the 3 categories of inhaled respiratory therapy devices?

Answer:

• pressurised Meter Dose Inhaler (MDI) w/wo inhaler
• breath activated inhaler
• dry powder inhaler (DPI) (acronym “ate”)
  
  • Accuhaler
  • Turbohaler
  • Ellipta

note: with all devices, pt must exhale deeply b/f inhaling meds
