A thin layer of water or a foggy look in the flow sensors is OK. • Ensure that water condensing in the breathing circuit tubes is kept lower than the flow sensors and is not allowed to drain into the flow sensors. • If Check Flow Sensors alarms occur during a VERY LONG case. replace the flow sensor module. • Drain all hoses as necessary. push the drain button before every case (listed in Pre-operative procedures). 4-26 07/01 1006-0802-000 . • Water condensation in the breathing circuit tubing can be eased using a Heat & Moisture Exchange (HME) filter at the airway connection. Solutions: • Drain the absorber each morning. • More moist. • With a circle breathing circuit. exhaled gas stays in the absorber. At lower fresh gas flows more water builds up because less gas is scavenged and: • More CO2 stays in the absorber to react and produce water. Allow the original flow sensors to dry before you use them again. Where does the water Water comes from exhaled gas and a chemical reaction between CO 2 and the come from? absorbent in the absorber.Aestiva/5 7100 How to prevent water build-up Why is water buildup a problem?

If necessary. Volume measurements come from two flow sensors in the flow sensor module. based on the user’s Plimit setting. A precision flow valve controls the amount of flow provided to the patient.

With circle circuit modules. If it is blocked.Aestiva/5 7100 Ventilator theory General The Aestiva/5 7100 ventilator pneumatics are located in the rear of the breathing system. small leaks and gas compression within the breathing circuit. Note that the 7100 provides a small amount of bleed flow through a pneumatic resistor to control the exhalation valve. The average volume changes due to compression in the breathing circuit is small (0. Electronic control of PEEP is achieved by maintaining a small amount of sealing pressure on the exhalation valve. The ventilator uses the other flow sensor to adjust the tidal volumes being delivered into the patient circuit tubing for changes in fresh gas flow. add the compression loss to the tidal volume setting (Volume Control mode). which changes with the flow. During exhalation. the sealing pressure on the exhalation valve is released and flow exhausts from the breathing circuit. Breaths are provided to the patient by sealing the exhalation valve and providing flow to the breathing circuit. wWARNING Do not try to silence the pneumatic resistor. A third pressure transducer measures the airway pressure at the outlet of the breathing circuit.25 ml/cm H2O). The transducer measures the pressure change across each sensor. the ventilator can malfunction and cause patient injury. There is no adjustment for compression in the patient circuit. Two tubes from each sensor connect to a transducer. smaller flow valve is used to control the exhalation valve sealing pressure. Safety redundant valves are used to limit the airway pressure. 8 Specifications and Theory of Operation Modes The system has two modes of mechanical ventilation: • Volume control • Pressure mode Use the main menu to set the mode. This is called tidal volume compensation. 1006-0802-000 07/01 8-17 .43. “V T Comp Off” continues to supply the set tidal volume but cannot compensate for the effects of fresh gas flow and breathing circuit compliance losses. The ventilator calculates a set flow and the length of the inspiratory period from the I:E and frequency settings. If tidal volume compensation is not enabled.068 Figure 8-2 • Volume control diagram Typically a volume control waveform shows increasing pressure during inspiration. the ventilator adjusts gas flow to the bellows based on measured inspiratory volumes. To make sure that the set flow is actually delivered. An optional inspiratory pause can be set to improve gas distribution in the lungs.” and Volume Control is replaced by Volume Mode in the main menu.

The ventilator is assumed to be operating in volume mode (Heliox OFF), with 100 percent oxygen in the breathing system; or, it is connected to an anesthesia gas analyzer. If the ventilator is operating without being connected to an anesthesia gas analyzer, additional errors may occur which are described in the “Gas composition related errors (both modes)” chart which is provided on the next page. Delivery accuracy Volume control: > 200 mL tidal volume: Better than ±10% of set V T. (100% O2) 75 to 200 mL tidal volume: Better than ±20 mL. < 75 mL tidal volume: Better than ±15 mL. V T comp off: Better than: ±15% of set V T. Pressure mode: Inspiratory pressure: ±2.0 cm H20 (repeatability only). (100% O2) PEEP: ±2.0 cm H2O (repeatability only). Monitoring accuracy Volume control: > 200 mL tidal volume: Better than ±10% of V T. (100% O2) 75 to 200 mL tidal volume: Better than ±20 mL. < 75 mL tidal volume: Better than ±15 mL. Pressure mode: Better than: ±2.0 cm H20 or ±5% of reading whichever is greater. 1006-0802-000 07/01 8-21 Heliox Mode The effect on volume delivery and monitoring accuracies of Heliox mixtures is within +8% to -15% when operating the Aestiva ventilator in the Heliox Mode. positive errors can have the effect of nulling out negative errors.87.5%/% volume agent in Heliox mode.
