  • Page 3: Description

    NIPPY JUNIOR + Positive Pressure Ventilator The Nippy jnr+ is a pressure controlled, positive pressure ventilator. It compresses ambient air and delivers it to the patient through a close fitting nasal mask or a tracheotomy. The output pressure, timing and alarms can be adjusted by controls on the fascia panel.
  • Page 4 Alarms Power Fail If the electrical power to the ventilator is interrupted, an audible alarm will sound. This alarm will run for 5 minutes unless cancelled with the mute button. Once cancelled the power fail alarm will not re-activate. Low Internal Battery When running on its internal battery, the alarm will operate when the battery is almost depleted The user cannot replace this battery.
  • Page 5 Estimated Tidal Volume The estimated tidal volume is a calculated value, based on time and calibrated flow values. The constant leak through the breathing circuit exhalation port is subtracted from this calculation to give a reasonably accurate estimation of tidal volume. The estimated tidal volume is displayed above the bargraph display.

  • Page 6: Intended Use

    Intended Use The Nippy jnr+ is designed to augment ventilation in children with acute or chronic type 2 respiratory failure. Patients who suffer form nocturnal hypoventilation are chiefly those with failure of the respiratory pump, though any concomitant lung disease is also deleterious. The main groups of patients who develop this problem are: - Patients with respiratory muscle weakness.

  • Page 19: Breathing Circuits And Masks

    Breathing Circuits Always use a 22mm bore breathing circuit when the High Flow alarm is set above 80 lpm. Always use a 15mm bore breathing circuit when the High Flow alarm is set below 80 lpm. The type of breathing circuit used will depend on the mode of ventilation selected:- Breathing circuits to be assembled in the order A-B-C-D from the ventilator end.

  • Page 20: Using The Nippy Junior+ Invasively

    Using the Nippy Junior+ Invasively The Nippy Junior+ is safe for use with a tracheotomy or endotracheal tube. An exhalation port must be fitted between the breathing circuit and the tracheotomy fitting. DO NOT USE THIS TYPE OF CIRCUIT FOR IPPV MODE 15mm dry circuit, Part Number 0806 Breathing circuit volume = 470 ml including filter.

  • Page 21: Setting Up

    SETTING UP THE NIPPY JUNIOR + in CPAP MODE 1. Place the Nippy Junior + on a clean, level surface. 2. Connect the breathing circuit tube to the outlet. It is recommended that a bacterial filter be fitted between the outlet and the 22mm diameter breathing tube. 3.

  • Page 22: Setting Up The Nippy Junior + In Pressure Support Mode

    SETTING UP THE NIPPY JUNIOR + in PRESSURE SUPPORT MODE Before starting to set up the ventilator, assess the patients breathing pattern. You will need to know the breath rate. Place the Nippy Junior + on a clean, level surface. Connect the breathing circuit tube to the outlet.

  • Page 23: Setting Up The Nippy Junior + In Pressure Control Mode

    SETTING UP THE NIPPY JUNIOR + in PRESSURE CONTROL MODE Before starting to set up the ventilator, assess the patients breathing pattern. You will need to know the breath rate and the approximate inspiratory time (Ti). Place the Nippy Junior + on a clean and level surface. Connect the breathing circuit tube to the outlet.

  • Page 24: Setting Up The Nippy Junior + In Ippv Mode

    SETTING UP THE NIPPY JUNIOR + in IPPV MODE Before starting to set up the ventilator, assess the patients breathing pattern.

  • Page 25: Setting Up The Alarms

    Setting Up the Alarms Automatic Setting For convenience, the high and low flow alarms may be set automatically. Varying leak or the patient getting out of synch with the ventilator may disrupt the measurement process. Therefore it is vital that the alarms are tested after setting up. Low Flow Alarm Press and hold the Low Flow Alarm button •...

  • Page 26: Alarm Conditions/Tests

    Alarm Conditions/Tests Test the alarms prior to use or daily for machines that are in constant use. Before testing alarms, ensure that the alarm is not muted. To cancel the Mute, press and hold the mute switch until a beep is heard (2 seconds). High Flow Alarm If the inspiratory flow exceeds the high alarm value, the alarm will be activated accompanied by the on-screen, high flow alarm message.

  • Page 27: Running On Battery Power

    Running the Nippy Junior + on Battery Power Nippy jnr+ may be powered from the mains, external battery or internal battery. When running on mains, the ventilator will recharge its own internal and/or external battery. Charge time is normally around 8 to 11 hours, per battery, depending on the ventilator settings.
  • Page 28 The run time may be as long as 12 hours for low values of CPAP with only moderate leak, or as short as 4 hours for Pressure Support at maximum pressure with quite severe leaks. Battery run times will typically be 20% more in IPPV mode because of the absence of the exhale port leak.

  • Page 29: Internal Battery

    Internal Battery Battery Test Test the battery if the running time seems low, a fault is suspected, or to confirm that the battery is good. • Ensure the battery is fully charged. • Run the ventilator from the battery until the low battery alarm operates and record the running time.

  • Page 30: External Battery

    External Batteries An external battery may be used to increase the running time. This battery is essentially the same as the internal battery and will power the ventilator for the same time, depending on settings and leak External Battery, part number 0910. External battery charger part number 0911 These batteries should never be used to run any other type of equipment.

  • Page 31: Battery Care

    Battery Care DO NOT use any other type of battery charger. This could lead to damage to the battery and personal injury. The battery should be recharged as soon as possible after use. • This type of battery does not suffer from the memory effect that is widely talked about •...
