ResMed CPAP S6 Clinician Manual page 7

Nasal CPAP therapy should be used with caution in patients with the following
conditions:
•
•
•
•
The clinician should assess on a case-by-case basis the relative risks and benefits of
CPAP therapy in such a subject. When assessing the relative risks and benefits, the
clinician should understand that the ResMed CPAP S6 unit can be set to deliver
pressures up to 20 cmH
pressures of up to 35 cmH
present a risk to a particular patient, then this device must not be used.
As with all fixed pressure and autotitrating CPAP units, the ResMed CPAP S6 unit
may not work:

For patients with limited respiratory capacity during sleep (eg emphysema; reduced
central drive; neuromuscular, chest wall or lung parenchymal disease; and similar
conditions), the use of the SmartStart/Stop feature may not be advisable. If the unit
is stopped inadvertently by this feature (due to leak, for example) the patient may
not breathe strongly enough to restart the unit.

incomplete reversal of upper airway obstruction or to breathing at high lung
volume, leading to worsening respiratory failure)

in the presence of severe mask leaks; furthermore, in the case of leaks in
excess of 0.7 L/sec, some or all reported parameters may be inaccurate, and
either insufficient or excess pressure may be delivered in some cases
with patients who breathe predominantly or exclusively through the mouth,
due to loss of pressure via the mouth; furthermore, some or all reported
parameters may be inaccurate, and either insufficient or excess pressure may
be delivered in some cases
in patients with lung disease, because the ResMed CPAP S6 system will treat
only the upper airway obstruction, and there may be residual hypoxaemia or
hypoventilation due to the lung disease
in patients with particularly high nasal resistance.
