Implication

Clinical evaluation demonstrates apnea monitors fail to differentiate ineffective respiratory efforts during airway obstruction in infants, highlighting critical monitoring hazards.

Key Points

To determine whether commercial apnea monitors can distinguish between ineffective respiratory efforts during upper airway obstruction and genuine alveolar ventilation.
Evaluated the response of two distinct types of apnea monitors to chest movements during upper airway obstruction.
Tested five healthy full-term infants during their first three days of life and two stable premature infants (gestational age 32 weeks, birth weights 1.30 kg and 1.32 kg) at 25 days of life.
Apnea monitors were assessed for erroneous interpretation of ongoing paradoxical or obstructed respiratory movements as normal breathing.
Devices exhibited susceptibility to false-negative alarms when upper airway obstruction occurred despite continuous chest wall motion.
