LOW SPO
2
Priority
Medium
Why it occurs
The measured SpO
2
is less than or equal to the Low SpO
2
alarm setting while the device is delivering
therapy or is in standby.
What to do
• Ensure that oxygen tubing is attached to the ventilator and the oxygen source.
• Ensure that the oxygen source is providing oxygen.
•
Increase oxygen flow or increase FiO
2
.
Requirements
Requires pulse oximeter
Device
performance
during active
alarm
The alarm is automatically resolved when the measured SpO
2
rises above the Low SpO
2
alarm setting.
Device will continue to operate.
Alarm Settings
50 to 95% in increments of 1%.
HIGH SPO
2
Priority
Medium
Why it occurs
The measured SpO
2
is greater than or equal to the High SpO
2
alarm setting.
What to do
• Ensure that the oxygen source is appropriate.
•
Decrease percentage of oxygen delivery.
Requirements
Requires pulse oximeter
Device
performance
during active
alarm
The alarm is automatically resolved when the measured SpO
2
falls below the High SpO
2
alarm setting.
Device will continue to operate.
Alarm Settings
90 to 100% in increments of 1%.
LOW ETCO
2
Priority
Medium
Why it occurs
The measured EtCO
2
is less than or equal to the Low EtCO
2
alarm setting for 10 seconds while the
device is delivering therapy.
What to do
Check the patient. If there is a tracheal tube, verify it is properly inserted. Verify that leak is not
excessive. High leak will reduce the measured EtCO
2
. Review the ventilation parameters including tidal
volume, minute ventilation and respiratory rate and verify that they are appropriate.

HIGH ETCO
2
Priority
Medium
Why it occurs
The measured EtCO
2
is greater than or equal to the high EtCO
2
alarm setting for 10 seconds while the
device is delivering therapy.
What to do
• Passive circuit: check for an insufficient leak
• Active and dual limb circuits: ensure the valve is operable
