Endotracheal tube cuff pressure assessment maneuver induces drop of expired tidal volume in the postoperative of coronary artery bypass grafting

Table 2 Absolute and percentual values of cuff pressure on P1 and P2

Variables	P1	P2
Cuff pressure (cmH ₂ O)	33.14 ± 4.66	30.86 ± 4.60 *
Percentual value (%)		93.00 ± 2.16 †

Data expressed as mean ± standard deviation with * p < 0.0001 in relation to P1 versus P2 comparison. P1 = pressure after cuff deflation/re-inflation to appropriated adjustment of pressures, and P2 = pressure after P1 mensuration. † Percentage of P2 in relation to P1.
