Relative contraindications (in the elective setting) are as follows:

  • Increased risk of aspiration: Prolonged bag-valve-mask ventilation, morbid obesity, second or third trimester pregnancy, patients who have not fasted before ventilation, upper gastrointestinal bleed

  • Suspected or known abnormalities in supraglottic anatomy

  • Need for high airway pressures (In all but the LMA ProSeal, pressure cannot exceed 20 mm water for effective ventilation.)
