Detaljeret beskrivelse
Persisting ventilatory failure associated with chronic obstructive pulmonary disease (COPD), obesity-hypoventilation-syndrome, sleep apnoea or neuromuscular disease is increasingly managed with domiciliary non-invasive positive pressure ventilation (NIPPV).
Optimal settings of non-invasive ventilation are usually titrated manually and require time and expertise. The development of systems lead to automated analysis and development of algorithms to adjust ventilators. However, there is a paucity of optimal algorithms, particularly the problem of upper airway obstruction. Therefore, the central aim of this study is to develop the automated setting of an end-expiratory positive airway pressure (EPAP), because upper airway obstruction is relatively common in this group of patients. We hypothesise that an automated end-expiratory airway pressure (AutoEEP) adjusting algorithm could overcome these problems and further optimise and adjust ventilator settings. Using non-invasive ventilation in patients with hypercapnic ventilatory failure, awake and asleep, we will measure physiological outcome parameters and apply an AutoEEP algorithm, comparing it against usual care.

Beskrivelse
Inclusion Criteria:
- Subjects will be patients not naive to noninvasive ventilation, and being so treated for any form of hypercapnic ventilatory failure.
- Previously stabilised on bilevel noninvasive pressure support ventilation.
- Both genders, age <75years.
- Previously shown to have a requirement for an EEP above cm H2O in order to maintain upper airway patency, or those in whom such a raised EEP would be expected, e.g. obese patients.
- Patients also known to have adequate airway patency at an EEP of 4 to 5 cm H2O will be included to ensure specificity of the algorithm.
Exclusion Criteria:
- Acute critical illness (e.g. acute coronary syndrome, stroke)
- Serious anatomical variations of nose, sinuses, pharynx or oesophagus.
- Any condition at risk of oesophageal bleeding (e.g. oesophageal varices, gastric ulcer, etc.)
- Age >75 years
- Pregnancy
- Epilepsy
- Psychiatric disorders that could possibly influence the study
- Any kind of addiction
- Insufficient knowledge of the language
- Noninvasive ventilation otherwise contraindicated

Foranstaltningsbeskrivelse |
Tidsramme |
---|---|---|
Index of Apneoas Plus Hypopnoeas Per Hour of Sleep (AHI)
Tidsramme: On completion of each consecutive night of polysomnography.
|
The AHI is a count of the number of pauses during sleep a person experiences.
The total number of apneas/ hypopneas (sleep pauses) are divided by the total sleep time to get an index for that night
|
On completion of each consecutive night of polysomnography.
