Mechanical Ventilation
Mind Map 1
What patients need
mechanical ventilation?
Respiratory failure
Failed NIV
Sepsis
Aggitation/cognition/mental state
Long term problems associated
with mechanical ventilation?
Critical illness myopathy
atrophy and loss of muscle mass
this atrophy can occur if patient
ventilated >48hrs
Requires acute and sub-acute physiotherapy for rehabilitation
Oxygen toxicity (damage to lungs)
Poor bone density
Psychological and cognitive effects of ICU admission
Different modes of
mechanical ventilation?
SIMV
patient gets set number of breaths of set volume
times mandatory breath with patient's spont breath
if no spont breath, ventilator will deliver breath
Pressure support ventilation (PS)
spont resp effort triggers pressure supported insp effort
Volume controlled (VC)
ventilator gives preset number of breaths with preset volume (similar to CMV)
Controlled mandatory ventilation (CMV)
preset number of breaths with preset volumes
for patients with no resp effort
Weaning from ventilation
ETT
Tracheostomy
High Flow O2 (Airvo)
Nasal prongs
Modes: aiming for modes that allow spontaneous breath and patient doing own work of breathing
Trajectory of Hospital admission
(in current workplace - Regional Hosp)
ICU
Discharged from ICU
Admitted to medical/cardiac/
surgical wards
Discharged home
Follow up through Day Hospital (if indicated)
In-patient rehabilitation
Home with community rehab/supports
Discharge home (no follow up) - large % of patients
Delivery of mechanical ventilation
Endotracheal tube (ETT)
Tracheostomy
Ventilator settings that Physio
need to assess
PEEP
Pressure support (PS)
Volumes
Fio2
Respiratory rate
Inspitation and expiration time - graph on vent screen
Physiotherapists role
in the ICU when a
patient is mechanically
ventilated?
Maintenance of joint ROM and strength
Early mobilisation inc mobilising on a ventilator (in line with hospital protocol) (assists weaning from vent)
Secretion clearance and assist airway ventilation (MHI, VHI, manual techniques)
Positioning of patient
Progression of function once extubated
How does the ICU team
decide on ventilator settings?
What are the 'usual' settings for an adult?
What are the precautions for a
mechanically ventilated patient?
