It is designed for use by Respiratory Therapists or other qualified and trained personnel under the direction of a physician and in accordance with applicable state laws and regulations.

• Page 13: Operator’s Safety Information

  Operator’s Safety Information All Operators are to read and understand the following information about Warning, Caution and ® Note statements before operating the LTV 1200 ventilator. WARNING “WARNING” statements alert the reader to potentially hazardous situations which, if not avoided, could result in death or serious injury.

• Page 14: Warnings

  Warnings WARNING ® Untrained Personnel – Only properly trained personnel should operate the ventilator. The LTV 1200 ventilator is a restricted medical device designed for use by Respiratory Therapists or other properly trained and qualified personnel under the direction of a physician and in accordance with applicable state laws and regulations.

• Page 15
  WARNING Battery run time — When the battery reaches the BAT LOW level, the ventilator will only run for approximately 10 minutes before generating a battery empty alarm (BAT EMPTY). The approximate time shown is based on tests using the nominal settings, a new battery and a full 8 hour charge cycle as specified in Appendix A — Ventilator Specifications.
• Page 16
  WARNING Ventilation Variables and O Consumption — Variations in the patient’s minute ventilation, I:E ratio and/or ventilator setting changes or equipment status (i.e. circuit leaks) affect the consumption rate of oxygen. When warranted by a patients condition, it is recommended that a back-up cylinder or alternative source of oxygen be available at all times.
• Page 17
  WARNING Low Minute Volume Control Settings — The Low Min. Vol. control should be set to its highest clinically appropriate value. If there is a clinical need to set the Low Minute Volume alarm to lower values or off (“- — -“), perform a clinical assessment to determine if an alternative monitor (i.e. a Pulse Oxymeter with an audible alarm, or a Cardio Respiratory Monitor) should be used.

• Page 34: Chapter 3 — Breath Types

  Chapter 3 — REATH YPES ® This chapter contains information regarding the breath types available on the LTV 1200 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 35: 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 36: 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 37
  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. ®…

• Page 38: 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 39: 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 the Pressure Support Flow Termination setting, or below 3 lpm. Spontaneous breaths may also be terminated by exceeding 2 breath periods.

• Page 40: Chapter 4 — Ventilation Modes

  Chapter 4 — ENTILATION ODES ® The LTV 1200 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.

• Page 41: Simv Mode

  SIMV Mode SIMV mode is selected when SIMV/CPAP is selected and the Breath Rate is set between 1 and 80. In SIMV mode, machine, assist and patient breaths may be given. For the first patient trigger detected within a breath period, an assist breath is given. For all subsequent patient triggers within the same breath period, spontaneous patient breaths or pressure support if set, are given.

• Page 42: Cpap Mode

  CPAP Mode CPAP mode is selected when SIMV/CPAP is selected and the Breath Rate is set to dashes “- -”. In CPAP mode, when a patient trigger is detected, a patient breath is given. Breaths will be Pressure Support or Spontaneous breaths according to the Pressure Support setting. NOTE ®…

• Page 43: Nppv Mode

  (PEEP). When a patient trigger is detected, a Pressure Support patient breath is given. NOTE Masks used with the LTV 1200 must be non-vented. With a vented mask, the patient’s exhaled air escapes via holes in the mask, elbow or swivel connector. With a non-vented mask, the patient’s exhaled air escapes through the ventilator exhalation valve.

• Page 44: Apnea Backup

  Apnea Backup ® The LTV 1200 ventilator provides an Apnea Backup mode of ventilation. Apnea Backup ventilation begins when the time since the last breath start is greater than the set Apnea Interval. When an apnea alarm occurs: • If an inspiration is in progress, the ventilator cycles to exhalation. •…

• Page 45: Volume Pressure Ventilation

  Volume Pressure Ventilation ® The LTV 1200 ventilator offers both Volume and Pressure ventilation. When Volume is selected, all machine and assist breaths are Volume Control breaths.

• Page 194: Chapter 14 — Power And Battery Operation

  Chapter 14 — OWER AND ATTERY PERATION ® The LTV 1200 ventilator operates on Direct Current (11 to 15 VDC), supplied by an external AC to DC power adapter, an external battery or other suitable external DC power source such as the Pulmonetic Systems Universal Power Supply or Transport Battery System.

• Page 195: Using The Ac Adapter

  Using the AC Adapter To run the ventilator from the Pulmonetic Systems AC Power Adapter: 1) Attach the power connector from the AC Adapter to the ventilator as shown here. 2) Connect the proper AC power cable (110V or 220V plug) to the AC Power Adapter. 3) Connect the 110V or 220V power cable to a suitable power source.

• Page 196: Using An External Battery

  Using an External Battery Optional External Batteries , Cables and Charger are available from Pulmonetic Systems.
