General Description TXP®-2D The TXP®-2D® is a high-frequency ventilator intended for the transport of neonatal patients. It is classified as a Pressure limited; Time cycled, High frequency, Flow interrupter. The ventilator consists of three main components: • Front panel. • Phasitron® patient interface with one-way failsafe and adjustable PEEP/Paw valve.
Airway Pressure Manometer Gives a visual indication of airway pressure in cmH O or kPa Mean Button Control When not depressed, Airway Pressure Manometer gives indication of Mean Airway Pressure. When button is depressed and held, Airway Pressure Manometer gives indication of Amplitude.

Frequency Counter When button is depressed, screen displays the high frequency rate in bpm.

Frequency Control Knob By rotating knob the high-frequency rate during ventilation is set. Range: 200-700 bpm Amplitude Control Knob By rotating knob the pressure or chest wiggle during high frequency ventilation is set.
PHASITRON® General The Phasitron® is the Mechanical/Physiological interface. Essentially the Phasitron® is a sliding venturi that acts as both the inhalation and exhalation valve (see below). Programmed gas from the face plate is introduced through the delivery port from the white line.
High-frequency details High-frequency The TXP®-2D delivers high- -frequency, flow interrupted breaths at 200-700 bpm. 700 bpm. (Approx. 3-10 Hz.) Goals of High-Frequency The aim of High-frequency is: frequency is: • Limit pressure exposure Limit pressure exposure • Optimize lung volumes where atelectasis is a major issue. Optimize lung volumes where atelectasis is a major issue.
Troubleshooting Symptom Cause Solution Volume too low. Check working pressure on Adjust working pressure to cylinders or wall. 50 psi Decreased compliance or Increase pressure and treat increased resistance. problem according to findings. Volume too high. Increase compliance or Decrease inspiratory decreased resistance.
Parameter Changes High-frequency • CO is HIGH o Maximize Amplitude o Decrease Rate Amplitude and Rate are interconnected; changing one parameter will affect other. • CO is LOW o Decrease Amplitude is HIGH • o Decrease FIO o Decrease MAP (By use of PEEP valve) •...
NO Set-up instructions • Replace standard Phasitron® swivel tee with NO swivel tee (if applicable) • Connect Aeronox® Injection port to Phasitron® NO Injection port. • Connect Aeronox® Monitoring port to Phasitron® NO monitoring port. • Connect red proximal airway port from TXP®-2D unit to proximal airway monitoring port.
These cleaning procedures supersede all others prior to January 29, 2007. PERCUSSIONAIRE® EQUIPMENT All new Percussionaire® products are packaged clean. They should not be considered sterile or decontaminated. Prior to use it is recommended that breathing circuit components be disassembled and sterilized/decontaminated.
If units are kept clean and water free, a three (3)-year life span between mandatory overhauls is a reasonable expectation. Units returned for maintenance and repair must be handled by a Percussionaire distributor. A return goods authorization number (RGA) can be obtained by contacting International Biomedical (512-873-0033).
