Ventilation- or Respiratory Support
- Ventilators and CPAP (Continuous Positive Airway Pressure)
- On this Page you will find Indexes to various aspects of
- Ventilation and CPAP and other airway support that may
- normally be utilized within NICU .
- Respiratory support may take a number of forms from the Positive Pressure (controlled) Intermittent Mandatory Ventilation, currently Provided at its most technical by the VIP Bird Ventilator.
- For our most distressed infants this is our preferred ventilator,
- <as pictured Below >
- VIP Bird Ventilator In Normal Use
- The larger lower part of the ventilator provides the set ventilation.
- The smaller unit on top measures the flow through a "Flow sensor".
- It is the results of this data which controls the ventilator by way of "Trigger sensitivity"
- This allows infant to have some control over the inspiratory time & rate.
- The other unit on top of the ventilator is the "Monitor", which displays the wave forms and loops of ventilation.
- Modes of Ventilation:
- SIMV - Synchronized IMV. - Synchronization of Breath with the Infants Efforts is an automatic function of Synchronized Intermittent Mandatory Ventilation.
- SIMV will synchronize only the number of breaths set in "Rate", additional breaths required by the infant are not assisted by the Ventilator, this mode is useful for Weaning from Ventilation.
- Assist Control - More control can be given to the Infant with the "Assist Control" mode.
- Each breath demanded by the infant is supported with a full Synchronized breath, the Rate setting becomes Minimum Rate, additional full synchronized ventilator breaths are provided as demanded by the infant.
- Termination Sensitivity - allows more control of the breath to the infant by terminating the breath when the flow/pressure has reached the percentage set, shortening the "I" time and allowing more breaths.
- < Patient Wye >
- Clear Corrugated. Expiratory Heater wire showing Blue Inspiratory Clear pressure.
- The breathing sensor is situated as close to the lungs as possible where the ventilatory circuit connects to the Endotrachial Tube via a Patient Wye.
- The White or Clear corrugated tube is the Expiratory tube, the "Expiratory Valve" closes the un-illustrated end to force ventilation.
- The Blue "Inspiratory" corrugated tube provides the Flow of Mixed Oxygen and Air, at the constant flow rate set on the Ventilator.
- The smaller clear tube monitors the airway pressure at the Wye.
- < Old 600 F&P Humidifier on CPAP > < Various Other Ventilators some used for CPAP >
- The Premixed Gas is Humidified via a Fisher & Paykel Humidifier. Supported on the Lower portion of the Ventilator or CPAP device stand.
- Temperature of the Gas is Monitored by a Temperature cable attached to the Inspiratory Limb of the Circuit.
- Humidity is assured by a Heater wire within the Inspiratory Limb of CPAP circuits or Both Limbs of Ventilator Circuits.
TroubleShooting !! First attend to the Infant.
Second Person attend to troubleshooting.Handy Hint:
The confused rush of activity at times of crisis
can be brought to better focus by following these simple steps:
- Take a step Back
- Take a deep breath
- Look and think through the steps you will take
- do Nothing without reason
- Click For Ventilator Click for CPAP Humidifier trouble
