Asthma: No BP (Adult)
 
Status
Pt loses cardiac output
- especially during assisted ventilation and bag becomes stiff
   
Pt requires immediate intervention
Apnoea 1 min
- Exclude tension pneumothorax
- Gentle lateral chest pressure
- Prepare for potential resuscitation
               
Cardiac output returns   Cartoid pulse, no BP   No return of output
Treat as per Asthma - Unconscious   Adrenaline IV, 50mcg
- Repeat Adrenaline IV 50-100mcg, 1 minutely as required
  Mx as per appropriate Guideline
    Normal Saline IV 20ml/kg    
 
Special Notes
Consider potential for tension pneumothorax and Mx.
Due to high intrathoracic pressure due to gas trapping, venous return is lost and Pt may lose cardiac output. Apnoea allows the gas trapping to decrease.
