DIAGNOSTIC PROCEDURES | |
CASE HISTORY INFORMATION:
There are three key elements clinicians need to pay attention to during the case history portion of a diagnostic evaluation in order to provide an accurate diagnosis.
1. Is the stridor constant or intermittent?
2. Is there any history of head trauma, stroke, or other brainstem
problems?
3. Are there any other associated symptoms, such as hoarseness,
dysphagia, glottus pharyngeus, or cough? (Koufman, 1994)
Questions to ask active patients if PVCD is suspected.
1. Do you have more trouble breathing in than breathing out?
2. Do you experience throat tightness?
3. Do you have a sensation of choking or suffocation?
4. Do you have hoarseness?
5. Do you make a breathing-in noise (stridor) when you are having
symptoms?
6. How soon after exercise starts do your symptoms begin? How
quickly do symptoms subside?
7. Do symptoms recur to the same degree when you resume exercise?
8. Do you experience numbness and/or tingling in your hands or feet or around your mouth with attacks?
9. Do symptoms ever occur in your sleep?
10. Do you routinely experience nasal symptoms (i.e. postnasal drip,
nasal congestion, runny nose, or sneezing)?
(Brugman & Simons, 1998)
