Airflow Obstruction and Treatment

These flashcards cover key concepts related to airflow obstruction, peak flow measurement, treatment options, and specific medications.

PEF measurement

Used to assess airflow obstruction.

Peak flow meter

Measures maximum expiratory flow

Repeated a total of 3 times and record 3 best efforts

Peak flow measurement

Green Zone

Indicates good airflow; 80-100% of predicted value.

Yellow Zone

Indicates caution; 60-80% of predicted value; may need medication.

Red Zone

Indicates emergency; less than 60% of predicted value; seek immediate medical attention.

Xanthines (Methylxanthine)

Class of drugs that stimulate bronchodilation and can act as a diuretic.

Theophylline

A methylxanthine used for asthma and COPD; no longer recommended as a first-line treatment. Contraindicated for exacerbation

Caffeine Citrate

A stimulant used for apnea of prematurity in neonates.

Apnea of Prematurity (AOP)

Condition where preterm infants experience pauses in breathing.

SABA

Preferred for acute asthma exacerbations.

GOLD guidelines
