I need to write paper 3 pages long double space . Please use pub.med for articles not older than 4 years . Also write in AMA format/style . Here part that I need to discuss in my paper :

Preoxygenation/Low Functional Residual Capacity, Apnea and Atelectasis risk.

Cost related to failure to prevent above things/increased hospital stay/unable to extubate or wake patient , prolong ICU stay.

Here some helpful hints :

Must preoxygenate the obese patient.

-safe apnea for obese is shorter than healthy patients due to high O2 consumption, decreased rib cage compliance, increased lung resistance, and most importantly, a reduction in Functional Residual Capacity (FRC)

-time needed to increase O2 sat is prolonged

-intubation is delayed due to difficult airway

-vital capacity and expiratory reserve volume are decreased

-downward diaphragmatic movements are limited

-greater atelectasis (put PEEP on ventilator)
