Before a patient can be set up on the ventilator, the various settings should be entered for the patient; this is the prescription.

To set up a prescription using the VIVO 55 ventilator, proceed with the following steps:

1. Turn on the machine, and make sure the device is in the clinical mode. If the device is in the ‘home’ mode, you will see a locked padlock on the home screen. To unlock the device, hold down the left and right arrow keys until the progress bar completes. The ventilator is now in the ‘clinical’ mode
2. Select the ‘mode’ menu from the five buttons along the bottom of the screen
3. Set the ventilation and breath ‘mode’ of the ventilator; ‘pressure’ or ‘volume’, and ‘support’, ‘assist control’, ‘MIPV’ or ‘SIMV’. Click ‘next’.
4. To change the clinical settings, scroll through the different parameters and set them according to the patient’s requirements. To change the settings, scroll left and right using the arrow keys, and to confirm the setting, select the down arrow to move to the next setting.
5. Once the clinical settings have been set, click ‘next’ to proceed to the alarm settings menu.
6. Scroll through the alarm settings to set the alarm triggers.
7. Once the alarm settings have been set, click ‘next’ to proceed to the circuit type menu: ‘exhalation valve’, or ‘leakage’ circuit.
8. To confirm all the settings, select ‘confirm’. The device will offer a ‘pre-use test’ which will run through a series of instructions for getting started with the current prescription.
