|
|
Greater than 60 bpm |
What is tachypnea |
|
|
Expiratory Grunting |
Due to “closure of epiglottis” |
|
|
Fine rales and diminish breatj sound |
It can be heard during auscultation in RDS and is due to poor air entry |

|
|
Survanta |
Its action is to restore surfactant as naturally occurring lung-surfactant to improve lung compliance |
