Bronchiolitis High Flow Nasal Cannula (HFNC) Management on Emergency and General Care Units
Prior to HFNC Initiation:
MD to order (using bronchiolitis order set)
Resident to notify Attending
MD to consider:
ξ Place PIV (consider normal saline bolus)
In ED:
ξ if unchanged: call PICU
ξ If improving: call pediatric hospitalist attending for
admission. Suction and VS q I hour while waiting to admit
On Floor:
ξ Suction at least q 2 hrs. until off HFNC, with VS q 2 hrs. x 6
hrs., then q 4 hrs unless clinical need for ↑ frequency
Weaning HFNC on general care unit:
FiO2 should be titrated by RT to maintain saturations>90% q1-
2 hr until 30%
HFNC flow rate should be weaned quickly in improving
patients, including at night. Wean flow by .5 q 1-2 hr until
≤3lpm as long as patient is:
ξ Clinically improving
ξ Requiring less than 30% FiO2
ξ WARM score is stable or improving
RT to assess using WARM Score prior to each wean and/or at
least q4 hour
RT to notify RN of any wean in flow
RN assess WOB and RR within 1 hour of wean in flow
When HFNC is stable at ≤ 3lpm for 2 hours, change to
humidified nasal cannula
ξ In ED: Call PICU if need > flow range
ξ On Floor: Call RRT if need > flow range
ξ Transfer patient to ICU if ≥ Max Flow of:
28 day-3 mo 12 Lpm
3 mo-12 mo 15 Lpm
13 mo-24 mo 20 Lpm
ξ Increase respiratory support with HFNC or other therapies
while awaiting transfer
Sign of clinical improvement (at least one):
ξ Improving WARM Score
ξ Lower respiratory rate (not inappropriately low for age)
ξ Lower heart rate
HFNC Inclusion Criteria
ξ On Pediatric Hospitalist Service
ξ Attending Hospitalist Notified
ξ On bronchiolitis protocol
ξ Age 28 days to < 24 months
HFNC Exclusion Criteria
One of the following:
ξ Patients excluded from bronchiolitis protocol
ξ Transported by CHETA on HFNC
ξ Exceeds Max general care unit flow/age
Meets Unstable Criteria
ξ FIO2 >50% to keep sats >90%
ξ Apnea
ξ Altered mental status (irritability, lethargy)
ξ Poor perfusion (cool extremities, capillary refill >
3 seconds)
ξ Bradycardia
ξ Concern for impending respiratory failure
Initiate HFNC in ED or general floor unit
FiO2 to maintain/titrate sats of > 90%
Age Flow
28 day-3 mo 4 Lpm
3 mo-12 mo 6 Lpm
13 mo-24 mo 8 Lpm
Huddle 60 minutes
post HFNC initiation/change.
In ED: RN, RT, EM resident/
attending and accepting floor
On Floor: RN, CTL, RT,
senior resident
Clinically worsening despite support increase or other clinical
Clinically unchanged or improving
Criteria for transfer to the ICU:
ξ Clinical worsening on HFNC trial
ξ Meets unstable criteria
ξ Meets General Care Max Flow/age
Criteria for transfer from the ICU to floor:
ξ Meets inclusion criteria, stable on flow rate at or
below the floor maximum for 8-12 hours
ξ If does not meet bronchiolitis HFNC management
on general care units, see HFNC policy
↑WOB despite standard bronchiolitis care
Is patient

Hospital, Wilson L, etal. Revised 10-17.
ξ ↑flow for ↑WOB
ξ ↑ O2 for ↓% saturations
ξ FYI Care team
In ED: Call PICU if needs ↑ flow rates
On Floor: Titrate flow to improve/
maintain WOB:
Age FlowRange
28 day-3 mo 4-8 Lpm
3 mo-12 mo 6-12 Lpm
13 mo-24 mo 8-15 Lpm
