Approach to Selecting Respiratory Support: -The role of noninvasive respiratory support is generally to reduce the patient's work of breathing, thereby avoiding diaphragmatic exhaustion. -The goal of noninvasive respiratory support isn't to immediately normalize the ABG. -Serial evaluation by experienced practitioners is generally far more useful than monitoring ABG values. -The choice of BiPAP vs. HFNC may be made on the basis of the patient's diagnosis (e.g. pneumonia vs. heart failure), not the ABG values. -BiPAP should never be used to “blow off” CO2 in a patient with hypoventilation due to drug intoxication. #Management #CriticalCare #BiPAP #BiLevel #HFNC #HighFlow #NIPPV #Noninvasive #Ventilation #RespiratorySupport #Selection #Algorithm #PulmCrit
