Attempted bag ventilation after intubation resulted in a massive air leak, necessitating swapping to a bag-valve-mask device. Eventually it was discovered that the lid of the breathing circuit module was slightly ajar, resulting in a leak around the expiratory valve (Figure 1).
Usually in the emergency setting a self-inflating bag-valve-mask device is used.
If pulse oximetry is available one can gauge from the patient's saturation how long to continue with intubation before (if unsuccessful) withdrawing and reventilating the patient with the bag-valve-mask device. Stop the intubation attempt when the saturation falls below 90%.
