It has been hypothesised that the increase in PEEP and the subsequent increase in intrathoracic pressure and reduced cardiac output may cause a dampening of the arterial pulse wave, such that the sensor has difficulty determining an arterial wave from a venous wave.
Leaving the packing for a longer period of time may significantly increase infectious complications in the setting of a foreign body and a significant amount of remaining intrathoracic clot.
