| Question : |
|
Why is number 99 called doctor's number ? |
Answer : |
|
For a doctor the number 99 is very important, because when he listens to the chest of a patient through Stethoscope, he
asks the patient to say repeatedly ninty nine. The normal resonance this vocalisation would cause is increased if the
underlined lung has solidified or became pneumonic. |
|
In other words vocalisation of nintey nine helps the doctor to
diagnose pneumonia at the bedside.
|
|
If you have ninety nine sounding louder than the normal in a particular area you know that the lung in that area has
become solidified or pneumonic. |
|
Pneumonia is the commonest cause of ninety nine becoming louder in any area of the lung.
