### Device Description

The Puritan Bennett™ Cuff Pressure Manager (CPM) continuously measures and automatically maintains cuff pressure during ventilation of patients using a cuffed endotracheal tube or tracheostomy tube. It is an integrated and continuous cuff pressure control solution that secures airway management in intensive care units, recovery room and during interhospital and intrahospital transport.

It operates in range of 5-50 cm H2O of user-set cuff pressures for various cuffed endotracheal tubes to provide suitable solutions for various clinical patient situations. The Puritan Bennett™ Cuff Pressure Manager introduces some new small features and convenient user interface to maximize safe use and usability. Both manual adjusting and one-click inflation function are provided alternatively for user's preference to start inflation. Measure mode allows user to observe the cuff pressure without device intervening before taking actions. Auto Key-lock feature help to avoid mis-operation when there's no user intervene for a long time. For inflation, room air is used and no contact to the respiratory gas system of a patient occurs. It is not intended to connect with ventilator.

The cuff pressure manager is designed with closed loop mechanism which is Pl controlled, and the software level of concern is Class C/Major concern.

The Puritan Bennett™ Cuff Pressure Manager is provided non-sterile and no re-processing is required. A sterile extension tube is equipped with the Puritan Bennett™ Cuff Pressure Manager for inflating/deflating or measuring cuff pressure. The associated accessories include:

- Extension Tube with filter Rechargeable Li-ion Battery Mounting Rack AC/DC Adaptor
### Intended Use / Indications for Use

The CPM is intended to continuously measure and automatically maintain the cuff pressure of an endotracheal tube or tracheostomy tube that has been set by the user/clinician during mechanical ventilation. The CPM is intended for use with adult and pediatric patients during mechanical ventilation in the listed areas:

Intensive care unit (ICU) Recovery room Emergency medical care Medical emergency vehicles when the patient is being transported During transport within and outside of the hospital

### Comparison of Technological Characteristics with Predicate Device

The intended use and indication for use for Puritan Bennett™ Cuff Pressure Manager is equivalent to those for the predicate devices, except for limitation of use in operation room, ship, jet and helicopter.

They are similar in fundamental scientific technology in that they are all multi-patient; controller is multiuse; extension tubes are sterile (EtO), single use; inflation/deflation of an endotracheal tube or tracheostomy tube; user set pressure; software controls pressure and automatic pressure maintenance; and AC and batter power supply.

The technical differences between the Puritan Bennett™ Cuff Pressure Manager and predicate device do not raise different issues of safety or effectiveness.
