Pneumogram technology has advanced significantly
since the introduction of the standard two
channel pneumogram. Physician requests to
correlate events with physiological changes
to improve their diagnostic ability prompted
the development of the multi-channel diagnostic
study. Multi-channel diagnostic studies provide
physicians with concurrent
information on cardiac, pulmonary and
GI system status.
Providing
this data makes differential diagnosis possible.
Correlation between apnea (central or obstructive),
bradycardia, O2 desaturation and gastroesophageal
reflux (GER) is documented as episodes occur.
Physicians trained in multi-channel analysis
believe that the additional data offers increased
diagnostic and management capabilities of
patients with cardiac, pulmonary, and GI system
abnormalities.
Indications
Patient
selection may include patients with one or
more of the following events/episodes:
- Apnea
- Bradycardia
- Tachycardia
- Stridor
- Cyanosis
- Abrupt,
Marked Pallor
- Hypotonia
- Apparent
Life Threatening Event (ALTE)
- Coughing,
Choking , Gagging
Diagnostic
Benefits
Simultaneous
and continuous recording of heart rate trend
or QRS complex, respiratory pattern, nasal
air flow, oxygen saturation, pulse rate, or
pH trend, helps in clarifying the significance
and etiology of each event/episode and can
help the physician to:
| Determine
the significance of Apnea |
| Differentiate
and Document Central, Mixed, or Obstructive
Apnea |
| Evaluate
the severity of each episode |
| Identify
Periodic, Shallow, and Disorganized
Breathing |
| Document
Hypoxemia |
| Identify
and document Hypopnea |
| Verify
medication effectiveness or impact of
its withdrawal |
| Correlated
Bradycardia or Tachycardia in relationship
to Apnea and/or O2 Desaturation
|
| Document
Cyanosis with Apnea |
|
Differentiative GER related Apnea
from Apnea related GER
