BMV

Q: During bag-mask ventilation (BMV), what is the best way to reduce the likelihood of decreasing gastric inflation? 


 Answer: Squeezing the bag slowly over one full second reduces the likelihood of decreasing gastric inflation. A slowly delivered tidal volume prevents sufficient pressure to open the gastroesophageal sphincter.

It also helps to prevent a dramatic impact on the cardiac output of a patient.
