Data presented as mean with standard deviation or median with interquartile range. Infants = <1 year old, young children=1-5 years old; older children=6-11 years old; adolescents=12-17 years old; adults = ≥18 years old. CP: Cuff pressure; TEE: Transesophageal echocardiography. *Infant cuff pressures significantly lower than young children (P=0.018), older children (P=0.001), adolescents (P<0.001), and adults (P=0.001). **Infant reset cuff pressures significantly lower than older children (P=0.028). ^†Infant TEE pressures significantly lower than older children (P=0.048), adolescents (P=0.02) and adults (P=0.00). ^‡Infant change in cuff pressures significantly lower than adolescent (P=0.007) and adults (P=0.002). ^∮P-values for the intragroup change in cuff pressure derived via Wilcoxon signed-rank test
