BJA article – prospective study on 38 patients with<br />
BMI >35 – laparoscopic surgery<br />
Pressure control vs. Volume control<br />
Pressure Control – better tidal volume , PaO 2 ,lesser<br />
A-a gradient, lower PaCO 2<br />
Peak inspiratory flow was higher in pressure control<br />
(52 liter /sec vs. 41 liter/sec)<br />
Tidal volume at ½ inspiratory time 67 % in pressure<br />
control ventilation <strong>and</strong> 53% in volume control<br />
ventilation<br />
Downsides – In laparoscopic surgeries with<br />
trendelenberg position- High risk for endobronchial<br />
intubation<br />
And what happens when the surgeon deflates the<br />
abdomen
