There are few reasons for keeping patient with higher position during PMV in use.

1. Better for lungs expansion during breathing;

2. To reduce the risk of aspiration;

3. Minimize irrational coughing

Usually the Dr. wants to draw ABG to check the patient’s acid and base balance. However, the ABG cannot tell you if the patient has “Patient-Ventilator Asynchrony” or not. “Patient -Ventilator Asynchrony” may cause the patient to show <font face=”inherit”>discomfort, anxiety and fatigue. The best tool to show “Patient-Ventilator Asynchrony” is the Ventilator waveform. Troubleshooting asynchrony is not easy to do, as you will need to learn ventilator waveform, figure out the causes, and requires clinical </font>experience.<font face=”inherit”> </font>

Most of the time, if you only look at ABG results you may not want to change any ventilator settings, because the results is acceptable. But if you look at his waveform, what do you think?

Admitted ABG on current vent setting:

PH=7.39, PCO2=64, PO2=62
HCO3=33.6, BE=11.3
Lactate=0.7
O2Sat=91.0
