Study Notes
BiPAP Titration
-
Decreasing BiPAP:
- Oxygen Reduction: First, reduce oxygen levels to 50-60%
- Pressure Reduction: Then, lower the CPAP pressure
- Goal: Aim for pressures around 5 cmH2O and FiO2 ≤ 30% for successful weaning from CPAP
BiPAP Settings
- Starting Pressure: Typically 12/6 (IPAP/EPAP)
- Increasing Ventilation: Increase the Delta (pressure support) by increasing IPAP, maintaining the difference between IPAP and EPAP
- Increasing Oxygenation: Increase EPAP, which is similar to CPAP and PEEP.
- Maintaining Delta: When increasing EPAP, also increase IPAP by the same amount to keep the Delta consistent. Example: If EPAP is increased from 6 to 8, IPAP should be increased from 12 to 14.
- Combined Ventilation and Oxygenation Issues: Increase both EPAP and IPAP to address both concerns. Example: Increase EPAP to 8 for oxygenation and IPAP to 16 for ventilation.
Pursed Lip Breathing
- Mechanism: Creates pressure within the airways and alveoli to prevent collapse, often caused by high intrathoracic pressures.
- Technique: Exhaling against partially closed lips (like whistling).
-
Indications:
- Asthma
- COPD exacerbations
- Other obstructive diseases
-
Benefits:
- Improved ventilation
- Removal of trapped air (CO2)
- Decreased work of breathing (WOB) and shortness of breath (SOA)
- Prevents rapid, shallow breathing by slowing the breathing rate.
BiPAP Titration
- Decreasing BiPAP titration should begin with reducing oxygen to 50-60%
- Subsequently, lower the CPAP pressure
- Weaning from CPAP is generally successful when pressures are around 5 cmH2O and FiO2 is ≤ 30%
- BiPAP starting pressure is typically 12/6
- Increasing the Delta, the difference between IPAP and EPAP, is the best approach for improving ventilation
- Increasing EPAP improves oxygenation
- EPAP is similar to the CPAP component of BiPAP therapy
- If increasing EPAP, IPAP should be increased by the same amount to maintain the Delta
- Example: If a patient is initially on 12/6 BiPAP with a desired Delta of 6, and EPAP is increased to 8, IPAP should be increased to 14 to maintain the Delta.
- If both ventilation and oxygenation are compromised, increasing EPAP for oxygenation and IPAP for ventilation will increase the Delta
Pursed Lip Breathing
- Acts as a "back-pressure" splint within the airways and alveoli, preventing collapse (atelectasis) often caused by high intrathoracic pressures
- Achieved by exhaling against partially closed (pursed) lips
- Indicated for:
- Asthma
- COPD exacerbations
- Other obstructive diseases
- Benefits include:
- Improves ventilation
- Removes trapped air (CO2)
- Decreases work of breathing (WOB/SOA)
- Prevents rapid, shallow breathing by decreasing breathing rate
BiPAP Titration
- Decreasing BiPAP titration should start with reducing oxygen to 50-60%
- Following oxygen reduction, lower the CPAP pressure
- When pressures reach around 5 cmH2O and FiO2 is ≤ 30%, patients can generally be weaned from CPAP
- BiPAP typically starts with a pressure of 12/6
- If ventilation needs to increase, prioritize increasing the Delta (pressure support)
- Delta is the difference between IPAP and EPAP
- Increasing EPAP helps with oxygenation, and EPAP is similar to PEEP and the CPAP component of BiPAP therapy
- If increasing EPAP, IPAP should also be increased by the same amount to maintain the Delta
- Example: If a patient is on 12/6 BiPAP and EPAP is increased to 8, IPAP should also increase to 14 to maintain a Delta of 6
Pursed Lip Breathing
- Creates back-pressure within the airways and alveoli to prevent collapse (atelectasis)
- Often used to combat high intrathoracic pressures
- Done by exhaling against partially closed lips, similar to whistling
- Helpful for conditions like asthma, COPD exacerbations, and other obstructive lung diseases
- Benefits of pursed lip breathing:
- Improves ventilation
- Removes trapped air (CO2)
- Decreases the work of breathing by reducing shortness of breath
- Prevents fast, shallow breathing by decreasing the breathing rate
