Figure 128: Adaptive Bi-Level Mode The Vte display shows the estimated Tidal Volume delivered to the patient calculated using the measured flow leak during EPAP. An estimated Leak is shown below the Tidal Volume field of the display. The Leak Estimate value is measured in lpm (See Figure 129) Figure 129: Leak Estimated Value in LPM In SW version 19.18.01 estimated leak in adaptive Bi-Level mode is presented in % (See Figure 130).
5 Adaptive Bi-Level EASY EXHALE Easy Exhale is an advanced feature of the iVent 201, minimizing the imposed exhalation valve resistance when PEEP > 0 is selected. By minimizing the exhalation valve resistance, we ensure as short exhalation time as possible thus reducing the risk of auto-PEEP.
NON-TRIGGERED BREATHS (INSPIRATORY TRIGGER FAILURE) Detection - Failure to trigger the ventilator is detected by patient dysynchrony with mechanical breaths. These are apparent as spontaneous efforts, on the flow waveform, which do not result in a rise in pressure on the pressure waveform. Intervention - Make sure that the enclosed volume of the facemask is not too large, or that the facemask is not poorly applied (see section under excessive leak).
Page 151
5 Adaptive Bi-Level Exclusion – Re-evaluate the patient's clinical status for causes of high respiratory drive to exclude premature I:E cycling and manage appropriately. Intervention – Lower the percent peak flow termination (Esens) and/or decrease the rise time. Use the waveform package to visualize waveforms and prolong the I-time until a visually detectable inspiratory flow termination pattern appears prior to pressure release.

In the event of any such change in specifications or design, Supplier shall be under no obligation to make the same or similar change in the Products previously produced or sold by the Supplier, unless the change is made to correct a safety or operational deficiency, or is required by the US Food and Drug Administration.
Appendix C: Operating Theory OPERATING THEORY THEORY The iVent 201 is a positive pressure mechanical ventilator. This appendix describes the ventilator’s components and depicts a schematic flow of the electro-pneumatic system. The function of each component is described below. AMBIENT AIR FILTER Air is drawn from the external environment through this filter.
TURBINE UNIT The turbine unit consists of a variable speed DC motor and a rotary compressor. The turbine unit generates flow and pressure by changing motor speeds. TURBINE PRESSURE SENSOR This sensor measures the pressure at the ventilator outlet. The ventilator software uses this value and the RPM of the turbine’s motor to control PEEP.
Appendix D: Theory of Breath Delivery BREATH DELIVERY The iVent 201 is a positive pressure mechanical ventilator that delivers air or air/oxygen mixture to the patient’s lungs under positive pressure. Each breathing cycle consists of two phases as described below (Figure 164). Figure 164: Pressure Breath Cycle An inspiratory phase, in which gas is delivered to the patient’s lungs and airway pressure increases.
Figure 165: Pressure and Flow Triggering by Patient 1. Pressure trigger. The breath is initiated when airway pressure drops below the baseline in an amount greater than the set sensitivity value. (a in the figure above). 2. Flow trigger. The breath is initiated when initial inspiratory flow generated by patient’s effort is greater than the set sensitivity value.
Appendix D: Theory of Breath Delivery Pressure control breath - mandatory breath in which the ventilator provides constant pressure at a preset level during inspiration. Patient Breath. Any breath in which the patient initiates and terminates the inspiration phase. This breath type is divided into two secondary types according to the method by which the inspiratory phase is controlled: Spontaneous breath - the ventilator helps the patient to breathe by maintaining the inspiratory pressure at the baseline level (PEEP).
The speed of change for peak flows and inspiratory times is based upon the difference between the current flow/ time and the required flow/ time. The greater the difference, the greater the step changes in peak flow or inspiratory time during the next breath. Most changes are gradual and may take 8 to 10 breaths to make a full change to the new patient condition.
Appendix D: Theory of Breath Delivery Figure 166: Volume Control Breath Waveform Inspiratory phase is terminated when set tidal volume (VT) is delivered. If Limit Pressure is set lower than Alarm Pressure, tidal volume may be decreased, when Limit Pressure is reached (c in the figure above). If the Adaptive Flow is selected, the inspiratory time is increased to reach the set tidal volume (d in the figure above).
Figure 167: Pressure Control Breath Waveform MANUAL MANDATORY BREATH A manual mandatory breath at the currently set parameters may be delivered at any time by pressing the Manual Breath button on the keypad. If this function is pressed during inspiration or during the minimum exhalation time, the ventilator waits and delivers the manual breath at the end of the minimum exhalation time.
Appendix D: Theory of Breath Delivery At that point, the ventilator terminates flow, allowing the patient to exhale. Figure 169: Pressure Support Breath Waveform PATIENT SPONTANEOUS BREATH A spontaneous breath is a patient breath which is initiated and terminated by the patient like a patient support breath.
SUMMARY The classification of breaths, for the purpose of this manual, are summarized in the following table.

Appendix D: Theory of Breath Delivery Notes:...
Appendix E: Ventilation Modes ASSIST/CONTROL MODE DEFINITION Assist/Control (A/C) mode combines two traditional modes of ventilation: Assisted Ventilation and Control Mechanical Ventilation (CMV). Unlike a pure Control Ventilation mode, a patient may breathe more frequently than the set respiratory rate by producing inspiratory efforts sufficient to trigger a mandatory assist breath prior to the end of CMV breath cycle.

Appendix E: Ventilation Modes Assist windows (any breath period). At the end of the Assist window when no patient efforts are detected. Spontaneous / Pressure Support breaths may be initiated and /or occur during support windows between mandatory breaths. Figure 171: Breath Patterns in SIMV Pressure Control and Volume Control Modes If a patient’s initiated breath overlaps with the next mandatory breath period, an Assist window opens, and the ventilator either waits for the next patient effort or...
CONTINUOUS POSITIVE AIRWAY PRESSURE MODE Definition Continuous Positive Airway Pressure (CPAP) is a ventilation mode intended for patients who are breathing spontaneously at a rate sufficient to meet their ventilation requirements. During CPAP, the airway pressure remains above ambient at all times, reducing the work of breathing. Available Breath Types Patient spontaneous and pressure support breaths can be delivered in this mode.
Appendix E: Ventilation Modes APNEA BACK-UP VENTILATION Apnea back up ventilation can be activated from all breathing modes. Visual and audible indicators indicate an apnea event if breathing has ceased for a period of time determined in the Alarms Settings window (the default value is 20 seconds.) When apnea is detected the patient is ventilated in the current ventilation mode except for CPAP.
Figure 173: Open Loop Warning Message If Standby was selected, the following Confirmation message pop-up window appears (Figure 174): Figure 174: Standby Confirmation Message The Open Loop ventilation is an approximation of the Volume Controlled ventilation with pressure limit. Ventilation is based on the average measured inhaled volume similar to apnea ventilation.
Appendix F: Hold Function and Static Mechanics Measurements FRONT PANEL CONTROLS The Hold Button has two functions. Pressing it results in the following: Pressed once initiates an end inspiratory hold maneuver which allows the calculation of static compliance (See Static Compliance Measurements, page 235).
RESPIRATORY TIME CONSTANT Lastly the ventilator calculates the time constant of the respiratory system as the product of the dynamic resistance and the static compliance of the respiratory system as calculated using the above technique. These calculated values can be viewed in the Respiratory Mechanics screen that is described in page 238 Reviewing Static Mechanics and Intrinsic PEEP Measurements.
Appendix F: Hold Function and Static Mechanics Measurements The duration of the inspiratory hold is dependent on the Tidal Volume of the patient. It is set according to the following table: Table 17: Maximum Inspiratory Hold Time for Different Tidal Volumes Tidal Volume Time Vt <...
proper I:E ratio for this patient. It may be necessary to increase the time interval between breaths in order to allow for more emptying. PERFORMING AND END EXPIRATORY HOLD MANEUVER To initiate an end expiratory hold maneuver, press the Hold button on the front panel twice in succession.
Appendix F: Hold Function and Static Mechanics Measurements RR/VT RATIO Clinicians are always looking for uncomplicated methods of determining if patients are capable of sustaining their own respiratory drive and being successfully “weaned” from mechanical ventilation.
