The HT50 Dual Pac Internal Battery System can provide hours of mobility and freedom for the
ventilator dependent person. Use these guidelines to help prolong that freedom.
1. Replace the primary internal battery every 12 months or sooner if the use time no longer
meets the user’s needs.
2. Replace the secondary internal battery every 24 months.
3. Always keep the Power Save function ON.
4. Always use an external power source when possible. Verify that the “Ext. Power” LED
is lit green when the HT50 is connected to external power.
5. Reset/clear latched alarm indicators so that the HT50 can resume Power Save.
6. Always have an alternate power source available.
7. Keep the Dual Pac Internal Battery System charged up.

EZ CAL (EXHALATION VALVE CALIBRATION)
Perform the EZ CAL each time you install a fresh circuit.
1. Connect the HT50 patient breathing circuit to the ventilator. Occlude the patient
connection.
2. Press the On/Standby button once to enter Settings condition.
3. Press the Manual Inflation button twice within three seconds.
4. The HT50 will start the EZ CAL and the ventilator will automatically test the
circuit. If it passes the test, the messages "Cal Completed", then "Press ON to
Vent" will be displayed.
4a. If the test fails, "Cal Failed" will be displayed.
4b. Press the Silence/Reset button.
4c. Check the integrity of the circuit, connections and accessories, then press
the Manual Inflation button twice to initiate calibration again.
5. When calibration is done, adjust patient settings appropriately, and press On/Standby
to begin ventilation.
Warning: Inadequate ventilation may result if the exhalation valve is not calibrated
properly. If the circuit/exhalation valve fails the calibration procedure, try another cir-
cuit/exhalation valve or use an alternate method of ventilation.
Warning: Some disposable breathing circuit/exhalation valve assemblies are not
compatible with the HT50 Ventilator due to the requirements of its sophisticated
servo-controlled, pressure management system. For best results, use a Newport
approved reusable HT50 breathing circuit /exhalation valve to ensure that the HT50
performs to specification.
Contact your Newport Medcial representative or Customer Service for a list of
breathing circuits that are compatible with the HT50.

I(0.1 to 49 L/min) – Press to select (flashing) the Low Minute Volume Alarm limit for
adjustment using ▲Up/▼Down buttons. A non-flashing display indicates the measured
inspired minute volume.
23. ▲Paw (Alarm) indicator – Flashing LED indicates a violation of the High Paw (airway
pressure) Alarm or High Baseline Pressure Alarm (built-in). Violation of this alarm terminates
the breath and a message appears in the Message Display Window.
24. ▼ Paw/Apnea (Alarm) indicator – Flashing LED indicates a violation of the Low Paw
Alarm, the Apnea Alarm Delay (no time or patient triggers are detected for 30 seconds) or
the Low Baseline Pressure Alarm and a message appears in the Message Display Window.

Minute Volume Alarm limit. A violation of this limit activates Back-up Ventilation (BUV). BUV
is unavailable for 60 seconds following a parameter change.
27. Device Alert (Alarm) indicator – Flashing LED indicates an internal ventilator problem.
Ventilation will cease. Use an alternate method of ventilation and send unit in for service.
Special Functions
28. Silence/Reset – Mutes the audible portion of all patient related alarms for 60 seconds (does
not silence Device Alert). It also clears any latched alarm indicators, when the alarm condi-
tion is no longer active. To adjust alarm buzzer volume, press and hold to toggle the alarm
volume between Loud and Quiet.
29. Manual Inflation – Press to deliver a manual inflation. Available in the A/CMV and SIMV
modes for both Volume and Pressure controlled breaths.

Blinking Yellow LED indicates a power switchover from external to internal (battery) power or
a low battery condition. Blinking red LED indicates an empty battery condition.A message
appears in the Message Display Window.
Press this button to display Battery Charge Level in the bottom of the Paw gauge. Red area
means not charged. Blue area means partially to fully charged. Test only when running on inter-
nal battery.
31. Humidifier On (19 ° to 39 °C) – (For model HT50-H/HT50-HB with built-in humidifier only)
Green LED indicates humidifier is active. Red LED indicates an alarm condition and humidifi-
er is turned off (alarm description is in Message Display Window). When pressed, the display
flashes and the target temperature can be set. Five seconds after an adjustment is made the
display stops blinking and measured temperature is displayed.
