Alarms and Safety

Alarms on the EO-150 are designed to ensure patient safety by alerting the user to conditions that require a response. When an alarm activates, it is both audible and visible. A message will appear on the screen, an alarm button on the top panel will flash, and a series of beeps will sound.

Alarms are categorized into two priorities: High and Medium.

  • High Priority: A red flashing light on the keyboard, a red alarm symbol on the touch screen, and 10 beeps every 6 seconds. These require an immediate response.
  • Medium Priority: A yellow flashing light on the keyboard, a yellow alarm symbol on the touch screen, and 3 beeps every 15 seconds.

Alarm Priority Cause/Ventilator Response Action Needed What to Do?
Total Power Loss High The alarm sounds continuously, there is no display, and it activates immediately. Check power connections. If the alarm continues, contact your service provider and use a backup ventilator. First, check all power connections to ensure they are secure. If the power loss continues, immediately contact your service provider and switch to a backup ventilator to ensure continuous patient support.
Disconnection High The circuit or accessory has disconnected. The alarm activates after one cycle or the set disconnection time, whichever is longer. Check all tube and accessory connections Immediately check all tube and accessory connections in between the device and the patient. Ensure everything is securely connected to prevent leaks and ensure proper ventilation.
Occlusion alarm High The patient circuit is blocked. Alarm activates after 5 seconds or 2 cycles after faulty monitored value is obtained  (maximum 30 seconds). Check all tube and accessory connections Immediately check all tube and accessory connections in between the device and the patient.are not obstructed.
AC power fail Medium Connection to AC power has been lost. Alarm activates after 1 second. Check power connections. If the alarm continues, contact your service provider and use a backup ventilator. Immediately check if the power cord is correctly plugged in to mains power and to the ventilator.
DC power fail Medium Connection to DC power has been lost. Alarm activates after 2 seconds. Check power connections. If the alarm continues, contact your service provider and use a backup ventilator. Check the power cord is correctly plugged into the DC source and into the ventilator.
INSP Flow Fail High Inspiratory flow sensor fails. The alarm activates after one cycle. Contact your service provider Immediately contact your service provider, as this indicates a potential sensor malfunction requiring technical assistance.
Valve Disconnected High The valve is disconnected. The alarm activates after one cycle. Reconnect the valve. Immediately check and reconnect the expiratory valve. This ensures proper airflow and pressure control within the ventilator system.
Valve Leak High There is a leak in the double circuit configuration. The alarm activates after six cycles. Inspect the circuit, expiratory valve, and proximal lines for leaks. Also, check for leaks around the mask if one is being used. Inspect the entire circuit, including the expiratory valve and proximal lines, for any leaks. Also, check the mask for a proper seal against the patient's face.
Rebreathing High In LEAK mode, the intentional leak is not at the level expected, or in VALVE mode, the valve is not correctly functioning. The alarm activates after 10 cycles (except in CPAP mode) or 10 to 40 seconds (in CPAP mode). In LEAK mode, check that the calibrated leak is present and the right size. In VALVE mode, check the valve function. In LEAK mode, verify that the calibrated leak is present and correctly sized. In VALVE mode, check the valve function to ensure it is working properly to prevent rebreathing of exhaled gases.
High Pres High The inspiratory pressure gets too high. The alarm activates after three cycles. Inspect the circuit or patient for occlusion. Inspect the patient circuit for any kinks or obstructions. Also, assess the patient for any conditions that might increase airway resistance, such as coughing or secretions.
Abs. Pres. Fail High The alarm activates after one second. Contact your service provider. Immediately contact your service provider, as this indicates a potential failure of the absolute pressure sensor requiring technical assistance.
Expi. Flow Fail High The alarm activates after one second. Contact your service provider. Immediately contact your service provider, as this indicates a potential failure of the expiratory flow sensor requiring technical assistance.
Speed Fault High The turbine speed is too low and the temperature is too high. The alarm activates after 10 seconds. Contact your service provider. Immediately contact your service provider, as this indicates a potential issue with the turbine's speed or temperature requiring technical assistance.
Vol. out of range High The maximum volume has been reached. The alarm activates after six cycles. Contact your service provider. Immediately contact your service provider. This may indicate an issue with the ventilator or sensor requiring technical assistance.
High FiO2 Medium The fraction of inspired oxygen is too high. The alarm activates after three cycles. Check the set FiO2 and the oxygen supply. Verify that the FiO2 setting is correct and that the oxygen supply is adequate to deliver the set FiO2. Adjust the settings or troubleshoot any potential issues with the oxygen supply as needed.
Low FiO2 High The fraction of inspired oxygen is too low. Alarm activates after 6 cycles or 20 seconds Check the set FiO2 and the oxygen supply. Immediately check that the FiO2 setting is correct and that the oxygen supply is functioning correctly. Adjust the settings or troubleshoot any potential issues with the oxygen supply as needed to deliver the set FiO2.
Low Battery Medium Battery capacity is low (30minutes of autonomy). The alarm activates after one second. Connect to mains power. Immediately connect the ventilator to mains power to maintain operation. If the battery continues to display low capacity, consider contacting your service provider to evaluate battery performance.
Battery Fail High The battery is not functioning properly. The alarm activates after three seconds.   Switch to a backup ventilator (for ventilator dependent patients). and immediately contact your service provider to investigate the cause of the battery failure.
