- Immediately disconnect from ventilator (allows for expiration of stacked breaths)
- "DOPES like DOTTS" Mnemonic
Troubleshoot
- D - Displacement of tube
- Attach end-tidal CO2 to verify and check depth (cm at lip)
- O - Obstruction of tube/circuit
- Use suction catheter to remove mucus plug, or make sure pt not biting down
- P - Pneumothorax
- Verify via US
- E - Equipment failure
- Connect to BVM
- S - Stacked breaths - Auto-PEEP especially in COPD/Asthma pts
- Disconnect from ventilator
- D - Displacement of tube
Fix
- Disconnect vent and put light pressure on pt chest
- Oxygen 100%
- Bag and take time to evaluate your patient
- Tube Position & Function
- Pass bougie or suction all the way through the tube, OR take a look with DL
- Tweak Vent Settings
- Drop TV, then decrease RR, and then increase flow rate
- Caution as it causes hypercapnia and resp acidosis, which is harmful in pts with increased ICP or tox ingestion
- Sonography
Auto-PEEP (Breath stacking) troubleshooting options
- Bronchodilators if COPD/asthma
- Decrease RR
- Decrease I:E ratio (increase expiratory time)
