  • Page 13: Overview

    We know that ventilatory support is critical in emergency situations. But for many of our cus- tomers, it is also a part of their daily lifestyle. The Newport HT70 Ventilators offer home care users the expanded mobility that allows them to experience more freedom in their lives than many have known before.

  • Page 14: Exceptional Mobility

    Introduction The twin micro-piston pump’s ability to deliver a variable flow enables the ventilator to provide a full range of operating modes and breath types with servo-controlled, leak-compensated PEEP. Leak compensation helps to improve triggering and avoid auto-triggering when a leak is present. The ventilator may be used with an endotracheal tube, tracheal tube, face mask, nasal mask or prongs, or mouthpiece.

  • Page 15: Travel Certified

    Travel Certified 1.2.3 The Newport HT70 Ventilator has been tested for and meets requirements for use in helicopter and fixed wing transport and for use on commercial airlines. Before traveling, be sure to speak with your airline representative about their particular concerns and clear all of your equipment with them well before your departure.

  • Page 16: Warnings, Cautions, And Notes

     WARNING: The design of the Newport HT70 Ventilator, the operating and service manuals, and the labeling on the ventilator take into consideration that the purchase and use of the equipment is restricted to trained professionals, and that certain inherent characteristics of the ventilator are known to the operator.
  • Page 17 Warnings, Cautions, and Notes  WARNING: Transport of patients with the Newport HT70 Ventilator requires that medical staff have a good working knowledge of the ventilator and methods for problem resolution. Proper emergency backup equipment must be immediately available during transport.
  • Page 18  WARNING: Always plug the Newport HT70 Ventilator into an external power supply source whenever it is available, even when the ventilator is not in use, to keep the internal dual battery system fully charged and to ensure best battery performance. Check battery capacity on the front panel before detaching from external power.
  • Page 19 WARNING: Always disconnect the external power supply prior to servicing.  WARNING: After servicing the Newport HT70 Ventilator, it must pass the operational verification procedure (OVP) before it is returned to patient use. See the service manual.  WARNING: Do not use electrically conductive breathing circuits. Always use clean and dry breathing circuits.

  • Page 133: 10 Explanation Of Modes And Controls

    10 Explanation of Modes and Controls A/CMV Mode 10.1 (Assist/Control Mandatory Ventilation) In A/CMV mode, all breaths are mandatory Volume Control or Pressure Control breaths, deter- mined by the selection on the touch screen. The RR setting determines the minimum number of mandatory breaths that are delivered each minute.

  • Page 134: Spont Mode

    Explanation of Modes and Controls SPONT Mode 10.3 (Spontaneous Ventilation) In SPONT mode, all breaths are spontaneous breaths that are flow/pressure-triggered by the patient. The user can adjust both PEEP/CPAP and Pressure Support (PS) levels. Reference page 10-2 for a description of how this breath type works. When PEEP/CPAP is set above 0, the ventilator mode is CPAP (without PS) or Bi-level Positive Airway Pressure (with PS).

  • Page 135: Backup Ventilation

    During Pressure Support, tidal volume is determined by the pressure change during the breath (PS setting), slope rise, expiratory threshold, PS max i-time, patient effort, and patient respiratory mechanics. 10.6 (Pressure Control Ventilation) Pressure Control mandatory breaths are available during A/CMV and SIMV modes. The ventilator targets and maintains patient airway pressure at the set Pressure Control level above ambient (not above PEEP) throughout inspiration.

  • Page 136: Backup Ventilation In A/Cmv And Simv Modes

    Explanation of Modes and Controls Backup Ventilation is functional in all modes. Backup Ventilation is not active for 60 seconds after the user adjusts ventilator controls, changes modes, or starts ventilation from the standby condition. During Backup Ventilation, the Audio Paused/Reset button can be pressed to mute the audible alarm.
  • Page 137 Backup Ventilation Patient Canceled If linked to low minute volume, when minute volume exceeds the Low Min Vol alarm setting by 10%, Backup Ventilation is canceled. If linked to Apnea alarm, after 2 minutes of Backup Ventila- tion, it is canceled. At that time, the audible alarm stops and the ventilator resumes ventilation at the user-selected parameters.
