NonInvasive Ventilation for Severe Cardiogenic Pulmonary Edema

Summary:

The use of non-invasive positive pressure ventilation (NIV) can reduce the risk for needing intubation and mechanical ventilation as well as rapid improvements in the clinical condition of the patient with cardiogenic pulmonary edema. The 2 most common forms of NIV include continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP) with BiPAP usually being the most comfortable for most patients since it offers some time period of lower pressure.

Criteria for Using of CPAP or BiPAP:

Patients who are candidates for CPAP or BiPAP should meet the following general criteria:

  • Awake
  • Able to follow basic commands
  • Protect their airway
  • Not actively vomiting
  • Not having seizures

Initial BiPAP Settings:

  • Common initial inspiratory positive airway pressure (IPAP) is 10 cm H20 (larger patients may need 15 cm H20)
  • Expiratory positive airway pressure (EPAP) is 5 cm H20
  • Adjust from there usually by 2-5 cm H20
  • Rate of 10-12 breaths per minute (can increase rate if needing to get rid of more CO2)
  • FiO2 initially is set at 100% and then titrated down once stabilized

Initial CPAP Settings:

  • Initial pressure settings are usually around 10 cm H20 and then adjust based on patients comfort or clinical response. Pressures range from 4 to 20 cm H20.
  • Rate of 10-12 breaths per minute (can increase rate if needing to get rid of more CO2) 
  • FiO2 initially is set at 100% and then titrated down once stabilized
