The NIH Adult Respiratory Distress Syndrome (ARDS) Network developed a ventilator strategy using a lower tidal volume. Once the tidal volume has been determined then other parameter can be set.


ventilator mode: volume assist/control


Other Parameters


respiratory rate

adjust to maintain minute ventilation; range 6 to 35 breaths per minute

ratio of length of inspiration to length of expiration periods

from 1:1 to 1:3


be careful increasing the respiratory rate when < 25 mm Hg


55 to 80 mm Hg


88 to 95%
