Page 35: Chapter 3 - Breath Types
Chapter 3 - REATH YPES ® This chapter contains information regarding the breath types available on the LTV Series ventilator. It covers how breaths are initiated, limited and cycled, and when each type of breath is given. The following terms are used in discussing how breaths are given: Initiate What causes a breath to be given.
Page 36: Volume Control Breaths
Volume Control Breaths For Volume Control breaths, the set Tidal Volume is delivered over the set Inspiratory Time and flow is delivered in a decelerating taper flow waveform. Peak flow is calculated based on the Tidal Volume and Inspiratory Time and the final flow is 50% of the peak flow. Volume breaths may be machine or assist type breaths.
Page 37: Pressure Control Breaths
Pressure Control Breaths For Pressure Control breaths , flow is delivered to elevate the circuit pressure to the Pressure Control setting and maintain it at that pressure for the set Inspiratory Time. Pressure Control breaths may be machine or assist type breaths. Adjusting the Rise Time Profile changes the flow and pressure waveforms for Pressure Control breaths.
Page 38 Pressure Control Breaths (cont) Pressure Control breaths have an optional flow termination criteria. If PC Flow Termination is on Pressure Control breaths may be time or flow terminated. If the flow drops to the set FLOW TERM level before the inspiratory time is completed, the inspiration is cycled. Pressure Control and Pressure Support breaths do not compensate for PEEP.
Page 39: Pressure Support Breaths
Pressure Support Breaths For Pressure Support breaths, flow is delivered to elevate the circuit pressure to the Pressure Support setting and maintain it at that pressure until the flow drops below a variable percentage of the peak flow. Pressure Support breaths may also be cycled by a variable time limit, or by exceeding 2 breath periods.
Page 40: Spontaneous Breaths
Spontaneous Breaths For Spontaneous breaths, flow is delivered to meet patient demand and maintain the circuit pressure at the measured PEEP from the previous breath. The breath is cycled when the flow drops below 10% of the maximum flow delivered during the breath, or below 3 lpm. Spontaneous breaths may also be terminated by exceeding 2 breath periods.
Page 41: Chapter 4 - Ventilation Modes
Chapter 4 - ENTILATION ODES ® The LTV Series ventilator provides the following modes of ventilation: • Control • Assist/Control • SIMV - Synchronized Intermittent Mandatory Ventilation • CPAP - Continuous Positive Airway Pressure • Apnea Backup Ventilation • NPPV - Non-Invasive Positive Pressure Ventilation Each of these modes is described below.

Appendix D - P RINCIPLES OF PERATION Overview ® The LTV Series ventilator utilizes an electromechanical pneumatic system under the control of a microprocessor to deliver patient ventilation. The following diagram and description illustrates the major components of the ventilator and their respective functions. Room air enters the ventilator through a flexible foam Inlet Filter.
Page 260 Ventilation flow enters the Flow Valve, which controls all inspiratory gas flow to the patient. The valve is driven by a rotary actuator, and translates circular motion to a poppet position, which in turn meters flow to the patient. The valve is characterized such that gas flow is a known function of differential pressure across the valve and actuator position.
