ZOLL does not offer a heated humidifier option for the unit. Users are cautioned to carefully
consider the ramifications of such use and the effect it may have upon device performance and
the patient's comfort. Such humidifiers have been shown to increase the work of breathing in
portable ventilators
accordance with directions provided by its respective manufacturer. Humidifiers are not
recommended for transport. Observe all safety and cautionary statements.
Warning!
Use of the HME or HME/Bacterial Viral filter (HMEF) may not be indicated in patients
with small tidal volumes as the dead space may be greater that 25% of the set Tidal
Volume. Always select an HME/HMEF that is appropriate for the patient. For very
small tidal volumes (50 to 75 ml), it may be advisable to not use an HME.
Warning!
Use of the HME or HME/Bacterial Viral filter (HMEF) will cause a slight increase in
the inspiratory effort to trigger an Assisted Breath (approximately 1 cm H
Warning!
Always monitor the patient and ventilator when using restrictive external filters or the
external O
compressor failure alarms under parameter configurations where high air flow is
required.
