Exercise and Lung function Flashcards
In exercise challenge test, dry air should be
<10 mg H2o/L
Exercise induced bronchoconstriction is fall in fev1 of
10-15%
Aerobic training programs duration
8-16 weeks
ECT parameter, ventilation to reach
17.5 to 21 times of fev1
in ect, saba dose
salbutamol 100 mcg - 2 to 4 puffs
or 0.5 ml
pre ect, avoid
it has higher sensitivity and higher PPV in asthma diagnosis vs ect
positive metacholine challenge test
mechanism of exercise induced bronchoconstiction
vascular theory
breathing POORLY CONDITIONED AIR at high flows for long period of times
HIGH VOLUMES with airway hyperemia obstructs airway
mechanism of EIB causing greatest EIB as compared with isolated challenge with cold air inhalation
facial cooling with warm or cold air inhalation (vagal effect)
emerging key player in triggering bronchospasm
neutrophil
increase IL ___ in exercise
IL 6
dose of caffeine protective against EIB
6-9 mg/kg
how many weeks max improvement of ICS in daily or frequent ICS
2-4 weeks
EIB is the earliest sign of ____
last symptom to disappear after ics
chronic asthma
mechanism of decreased exercise capacity in CF patients
peripheral/muscle limit
respi limit
genotype
training
Exercise at high altitude
