Title: Obesity and Mechanical Ventilation<br/>Author: Mike Winters<br/><a href='http://umem.org/profiles/faculty/141/'>[Click to email author]</a><hr/><p>
<u><strong>Mechanical Ventilation in the Obese Patient</strong></u></p>
<ul>
<li>
Obesity can result in decreased lung volumes, decreased lung and chest wall compliance, and increased work of breathing.</li>
<li>
Unfortunately, there is very little literature to guide the emergency physician on mechanical ventilation in obese patients.</li>
<li>
A recent study of intubated ED patients by Goyal, et al found that over 1 in 5 patients were ventilated with potentially injurious tidal volumes.</li>
<li>
Importantly, obesity increased the odds of inappropriate ventilator settings.</li>
<li>
In the intubated obese patient, be sure to set tidal volume based on <strong>ideal body weight</strong> and consider starting with a <strong>higher PEEP setting</strong> (i.e., 10 to 15 cm H2O).</li>
</ul>
