General information
Contraindications The Respironics V60/V60 Plus Ventilator is contraindicated for patients with
any of the following conditions:
• Lack of spontaneous respiratory drive
• Inability to maintain a patent airway or adequately clear secretions
• At risk for aspiration of gastric contents
• Acute sinusitis or otitis media
• Hypotension
• Untreated pertussis
• Epistaxis (nosebleed)
About CO
2
rebreathing
As with mask ventilation in general, patient CO
2
rebreathing may occur under
some circumstances. Follow these guidelines to minimize the potential for CO
2
rebreathing. If rebreathing is a significant concern for a particular patient and
these guidelines are not sufficient to acceptably reduce the potential for CO
2
rebreathing, consider an alternative means of ventilation.
• Increase EPAP to decrease the potential for CO
2
rebreathing. Higher
pressures produce more flow through the exhalation port, which helps
to purge all CO
2
from the circuit to prevent rebreathing.
• Be aware that the potential for CO
2
rebreathing increases as
inspiratory time increases. A longer inspiratory time decreases
exhalation time, allowing less CO
2
to be purged from the circuit before
the next cycle. In such circumstances, higher tidal volumes further
increase the volume of CO
2
rebreathed by the patient.
Potential side effects Advise the patient to immediately report any unusual chest discomfort,
shortness of breath, or severe headache. Other potential side effects of
noninvasive positive pressure ventilation include: ear discomfort,
conjunctivitis, skin abrasions due to mask/patient interface, and gastric
distention (aerophagia). If skin irritation or breakdown develops from the use of
the mask, refer to the accompanying mask instructions for appropriate action.
