Introduction
AIMS
• Patients at risk for unsuccessful weaning from the mechanical
ventilation in the ICU
• The interplay of ICU and HDU / specialised ward for successful
transfer from the hospital to the home
• Real-life case scenario
![Page 3: NIV: Transition from ICU to home · Difficult weaning foreseen HV patient admitted ↔ Gather information Deliver information Arrange parent/medical team meeting ↔ Get actively](https://reader035.vdocuments.site/reader035/viewer/2022070714/5ed61fb636f34201e03b4603/html5/thumbnails/3.jpg)
Question 1
Where do you work?
1. Pediatric ICU
2. Pediatric HDU / Ward
3. Adult ICU
4. Adult HDU / Ward
5. Other
![Page 4: NIV: Transition from ICU to home · Difficult weaning foreseen HV patient admitted ↔ Gather information Deliver information Arrange parent/medical team meeting ↔ Get actively](https://reader035.vdocuments.site/reader035/viewer/2022070714/5ed61fb636f34201e03b4603/html5/thumbnails/4.jpg)
Question 2
Does your hospital have ICU /
HDU / Ward interdisciplinary
meetings (other than direct
patient care)?
1. Yes
2. No, but I would wish to
3. No, not realistic

NIV after extubation

• There are insufficient data to recommend the routine use of non-invasive respiratory
support after extubation for any patient category.
• However, early application of NIV combined with cough-assist techniques should be
considered in neuromuscular diseases to prevent extubation failure (strong
agreement).

Fine-Goulden MR et al. Lancet Respir Med. 2015;3(10):745-6
„Children with neuromuscular and
neurological disorders are least likely to
wean off “ [mechanical ventilation].
„Children with severe physical and
cognitive disabilities are also
increasingly offered long-term
ventilation to prolong life, with no
expectation of weaning.“

In the HDU / on the ward
Main goal: Going home / chronic care facility
Escarrabill J. ERS Practical Handbook of Noninvasive Ventilation, 2015
Getting ready → discharge planning:
• Assessment of the patient
• Planned interventions by the multidisciplinary
team
• Structured therapeutic education for the patient
and their carers
• A follow-up programme
![Page 19: NIV: Transition from ICU to home · Difficult weaning foreseen HV patient admitted ↔ Gather information Deliver information Arrange parent/medical team meeting ↔ Get actively](https://reader035.vdocuments.site/reader035/viewer/2022070714/5ed61fb636f34201e03b4603/html5/thumbnails/19.jpg)
Assessment - NIV optimisationInterface adaptation
• Change for nasal, minimal contact mask
Ventilatory settings optimisation
• General condition changes after ICU discharge
Overnight oximetry / PG
• Verification of efficient ventilation
Secretions management
• Cough assist, efficient cough support
Is the patient ready?
Stable condition - no ventilatory settings/oxygen changes for several days on home device.

Structured education for the parents /carer
Parent / carer must:
• Get basic clinical knowledge
• Be familiar with equipment use and maintenance
• Be proficient in basic technical skills
• Efficiently solve basic emergency events
• Be trained in secretion clearance techniques
Systematic knowledge examination must be made.
If available, teaching in a simulation centre can be perused.

• Deliver support and guidance
• Optimal equipment (device / interfaces)
• Experience

Conclusions
• An increase in complexity and morbidity has been seen
in children leaving the ICUs.
• Children with different chronic conditions are at risk for
difficult weaning (specially neuromuscular diseases ).
• The number of children on long term (non-invasive and
invasive) ventilation is rising.
![Page 41: NIV: Transition from ICU to home · Difficult weaning foreseen HV patient admitted ↔ Gather information Deliver information Arrange parent/medical team meeting ↔ Get actively](https://reader035.vdocuments.site/reader035/viewer/2022070714/5ed61fb636f34201e03b4603/html5/thumbnails/41.jpg)
Conclusions
• Effective communication and the continuum of care
between ICU and HDU/specialised ward is the key to
success in ventilatory management.
• Structured discharge planning enables safe transfer of
ventilator-dependent children from the hospital to the
home.
• Adequate education and empowerment of parents/carers
allows for successful home care of complex, technology
dependent children.
