1Exercise Challenge Testing:
Assess hyperreactivity when [blank_start]heat[blank_end] and [blank_start]moisture[blank_end] are lost from upper airways during exercise.
[blank_start]Bike[blank_end] or [blank_start]treadmill[blank_end] is used to get HR [blank_start]80[blank_end]-[blank_start]90[blank_end]% of max for [blank_start]6[blank_end]-[blank_start]8[blank_end] minutes.
Monitor: ECG, BP and SpO2
Post exercise: Spiro is done [blank_start]immediately[blank_end] then every [blank_start]5[blank_end] minutes until [blank_start]FEV1[blank_end] reaches it's [blank_start]lowest[blank_end] then returns to normal.
[blank_start]15[blank_end]% drop in FEV1 is a [blank_start]positive[blank_end] test
If FEV1 drops by 10-15% administer a [blank_start]bronchodilator[blank_end]- Aheat

2Eucapnic Voluntary Hyperventilation:
Assess airway hyperreactivity by havin pt breathe at high rate of [blank_start]ventilation[blank_end].
Removes [blank_start]heat[blank_end] and [blank_start]moisture[blank_end] from upper airway
Pt breathes gas mix of [blank_start]5[blank_end]% CO2, [blank_start]21[blank_end]% O2, with balance [blank_start]N2[blank_end].
Spirometry is performed [blank_start]immediately[blank_end] after and every 5 minutes for [blank_start]20[blank_end] minutes.
If FEV1 drops by [blank_start]15[blank_end]%, the test is positive. If FEV1 does not drop after [blank_start]20[blank_end] minutes, test is [blank_start]negative[blank_end]

3Mannitol Tolerance Test
Withhold SABA [blank_start]8[blank_end] hrs, all other meds [blank_start]12[blank_end] hrs. No [blank_start]caffeine[blank_end]
Mannitol stimulates release of [blank_start]mediators[blank_end] that act on bronchial smooth [blank_start]muscle[blank_end].
Sensitive for asthma and used to [blank_start]monitor[blank_end] disease activity and assess [blank_start]antiinflammatory[blank_end] therapy.
[blank_start]Dry[blank_end] powder in special inhaler. Color coded for [blank_start]0[blank_end], [blank_start]5[blank_end], [blank_start]10[blank_end], [blank_start]20[blank_end], [blank_start]50[blank_end] mg doses
Full insp with 5 second hold is done with flow 60 L/min.
After [blank_start]60[blank_end] seconds, do spirometry, repeat at higher doses until [blank_start]15[blank_end]% drop in Fev1
[blank_start]PD15[blank_end]% is reported
Avoid smoking for [blank_start]6[blank_end] hours, avoid [blank_start]exercise[blank_end] on day of test- A8

4MIP
Largest amount of [blank_start]negative[blank_end] inspiratory pressure that can be generated against an occluded airway
Manometer with flanged mouthpiece and 3 way stopcock.
Typical Value = [blank_start]-60[blank_end] cmH20
Pt expires to RV, occlude mouthpiece, pt inhales maximally for [blank_start]1[blank_end]-[blank_start]3[blank_end] seconds.
Small [blank_start]leak[blank_end] is built in to offset cheek movement
Assess muscles strength: Will be decreased in [blank_start]neuromuscular[blank_end] disease, disease involving diaphragm, chest wall or spinal deformities- Anegative
- B-60
- C1
- D3
- Eleak
- Fneuromuscular
5MEP
Maximum positive pressure that can be generated during forced expiration against occluded airway.
Same equipment as [blank_start]MEP[blank_end]
Typically [blank_start]80[blank_end] - [blank_start]100[blank_end] cmH2O
Pt inhales to [blank_start]TLC[blank_end], airway occluded, then pt exhales forcefully
Will be decreased with [blank_start]neuromuscular[blank_end] disease, especially generalized weakness. Decreased with emphysema, chronic bronchitis, CF and inability to cough.- Aneuromuscular

6Methacholine Challenge testing
PC20
[blank_start]Provacative[blank_end] concentration used to determine if pt had [blank_start]positive[blank_end] methacholine challenge. The concentraion of methacholine that made pt drop [blank_start]20[blank_end]% in FEV1
Prohibited Activities
Avoid any activity that may induce [blank_start]bronchospasm[blank_end]. Irritants, exercise, work- AProvacative
- Bpositive
- C20
- Dbronchospasm
