Back-up Ventilation. DuoFlow PLUS (with Time-Limited Demand Flow). 8 hour Internal Battery Back-up. Built-in Air/Oxygen Mixer The compact size and advanced features of the E100M allow it to easily fit in those areas of the hospital where space is limited and ease of use is appreciated; for emergency room, intra-hospital transport, post anesthesia recovery, etc. For subacute and long term care applications the E100M offers improved comfort for patients and low cost of ownership for facilities. Value - The Newport E100M is designed to deliver reliability and versatility. It is ideal for most patient applications, eliminating the need for and expense of age specific or application limited equipment.
Performance - The Newport E100M features comprehensive functions which are easy to learn and easy to use. New advances, such as Advanced Trigger Control and Auto-Set Alarms, simplify the set-up and management of the ventilator. The DuoFlow PLUS system allows you to improve comfort, synchrony and work of breathing for spontaneously breathing patients. And the system's extensive monitoring, alarm systems and built-in battery provide you with added security and safety. On a cost per feature ratio, your best investment for performance and reliability is the E100M. Flexibility - The Newport E100M mounting and set-up options offer you more flexibility. Adding a compact air compressor allows use of the ventilator where piped-in gas is not available.
Mounted on a stand and pole, the E100M is compact and stable for easy mobility. The optional E-cylinder holders streamline patient transport. Safety - The Newport E100M features maximum patient safety with added functions including Apnea Back-up Ventilation and a Remote Alarm Outlet. When the Auto-Set Alarm button is pressed the E100M automatically selects high and low pressure alarm settings and the built-in battery allows 6 to 8 hours of intra-hospital transport or emergency power operation. Special Features:.
DuoFlow Plus As you wean a patient, you may gradually decrease the number of mandatory breaths and rely on the patient to take over more responsibility for ventilation with spontaneous breaths. Weaning success may be affected by how the patient tolerates the increase in work load. ‚ Newport's unique DuoFlow PLUS system allows you to make the patient more comfortable during spontaneous breathing by providing a higher flow at the onset of effort which drops to a lower flow as effort subsides. This can ease patient work for spontaneous breathing and also help to decrease expiratory resistance, improve mandatory breath triggering and decrease ventilator gas consumption. ‚‚‚‚. Advanced Trigger Control Throughout the patient's course of mechanical ventilation, circuit leaks or physiologic changes may impact the effectiveness of the Trigger setting.
Since an appropriate Trigger setting is essential for maintaining patient/ventilator synchrony, the bedside clinician must re-adjust Trigger regularly to keep the ventilator sensitive to patient efforts without artifact triggering. ‚ With Newport's introduction of Advanced Trigger Control (ATC), a simple push of a button ensures that the Trigger setting is automatically re-adjusted as patient or circuit conditions change. The ATC feature can provide improved patient/ventilator synchrony even when you cannot be at the bedside. ‚‚. Interface Output The E100M features an RS232 Output to interface with a central monitoring system and a 4:1 Inverse Ratio capability which can provide greater ventilation flexibility.
‚‚. Comprehensive Monitoring Includes Peak, Mean and Base Airway Pressure, Set Tidal Volume, I:E, Total Frequency and% Battery Charge.

NOTE: HOME CAREGIVERS: This parameter should always be set to USER for home use to ensure that when the HT50 is powered off and on the physician directed ventilation settings remain in place. Auto Panel Lock This setting allows the user to enable (turn on) or disable (turn off) the Auto Panel Lock feature. THEORY OF OPERATION General System Overview.4-1 A/CMV Mode (Assist/Control Mandatory Ventilation).4-2 SIMV Mode (Synchronized Intermittent Mandatory Ventilation).
There is an Auto-Lock feature that may be enabled or disabled. The alarm loudness may be set to two different levels. The HT50 may be operated from a variety of AC (100-240 VAC @ 50 / 60 / 400 Hz) or DC (12-30 VDC) external power sources or from the Dual Pac Internal Battery System. 30 minutes operating time remains. The HT50 is available with a built-in humidifier or without. The HT50 is very easy to set up and use with clear indications of all ventilation and alarm settings and alarm violations. This limits the number of mandatory breaths (time triggered or patient triggered) the patient ƒ receives in 60 seconds to the (b/min) setting.
As with all HT50 operating modes, Back-up Ventilation is activated. if the Low MV alarm limit is violated. THEORY OF OPERATION When PEEP/CPAP is set above 0, the ventilator mode is CPAP (without P support) or Bi-level Positive Airway Pressure (with Psupport). Ensure that P trig is set so the HT50 detects all spontaneous patient efforts. Ƒ Entries for tidal volume, pressure control, t I and Low Paw alarm limit are all inactive in SPONT mode. This will not cancel Back- up Ventilation.
NOTE: Back-up Ventilation in the HT50 is based on the delivered inspiratory minute volume. The inspiratory minute volume may be different from the expiratory minute volume in some conditions, such as in the case of a patient breathing circuit or patient airway leak. 10%, Back-up Ventilation is cancelled, the audible. alarm stops, the Low MV (Back-up Vent) alarm indicator latches and the HT50 resumes ventilation at the user-selected parameters. Press the Silence/Reset button to cancel the latched alarm indicator and alarm message in the Message Display Window.
Battery Test.5-10 Humidifier (for HT50-H).5-11 OVP Test Record. SECTION 5 INTRODUCTION This procedure is intended to assist a Newport authorized service technician to establish a routine verification program to verify proper operation of the HT50 Ventilator (p/n HT50-H1, HT50-H1-B, HT50-H). An OVP must be performed each time the ventilator is serviced or a minimum of once a year. CALIBRATION / OPERATIONAL VERIFICATION PROEDURE PRE-TEST INSPECTION Refer to Figure 9-1.
General Inspection. Inspect the patient breathing circuit, exhalation valve, and 500 cc test lung for any deterioration which may cause leaks in the system. Replace any defective parts prior to performing the OVP. Newport technical support. Connect the ventilator to A.C. SYSTEM LEAK TEST 1. Set the HT50 to Standard Test Settings.
Check the 3 thumbscrews of the inlet filter cover in order to ensure no leakage around the cover. CALIBRATION / OPERATIONAL VERIFICATION PROEDURE NOTE: If system leak test fails and the leak exists in the pneumatic system between the manifold and patient circuit, calibration shall be performed again after the leak is fixed. PRESSURE TRANSDUCERS CALIBRATION 1.
Connect the T-connector between the patient fitting on the exhalation valve and a test lung. SECTION 5 PRESSURE METER CALIBRATION 1. Battery button to scroll to “Meter Cal.” 2.
Press the LUp control button to select “Meter Cal.” The Message Display Window will display “Adjust to 0.” 3. Use the LUp/MDown control buttons to adjust the Paw needle to 0. CALIBRATION / OPERATIONAL VERIFICATION PROEDURE PRESSURE RELIEF VALVE CALIBRATION 1. Battery button to scroll to “Adjust Rel Valve.” 2. Block the Mainflow outlet using CAP100P, and press the LUp control button. This will start the motor and pressure in the system will begin to rise.
Press the Manual Inflation button once, then again within three seconds. The HT50 will start the exhalation valve calibration and the ventilator will automatically test the exhalation valve. If it passes the test, the messages 'Cal Completed', then 'Press ON to Vent'. CALIBRATION / OPERATIONAL VERIFICATION PROEDURE PRESSURE VERIFICATION 1. Connect the T-connector between the test lung and the exhalation valve. Connect the tubing from the T-connector to a calibrated pressure gauge.
Press the LUp control button to select “Paw P M B” in the Message Display Window. Remove T-connector, leaving the Rp50 inline. EXHALATION VALVE SEALING 1. Set the HT50 to Standard Test Settings. Set the ƒ to 5. Change the Volume Control setting so that the Paw meter reaches 70 ±5 cmH O/mbar during inspiration. Verify that the audible alarm ceases.
Press the Silence/Reset to clear the visual alarm.
