There are 7 clinical trials
Central sleep apnea (CSA) is common in patients with heart failure and those using opioid analgesics. Unfortunately, effective treatment of central apnea remains elusive, pressure therapy given the modest efficiency of positive airway pressure therapy. The focus of this proposal is to identify mechanistic pathways to guide future therapeutic interventions for central sleep apnea based on the strong premise that multi-modality therapy will normalize respiration and hence mitigate adverse long-term consequences of CSA. The investigators' proposed studies will test combination therapies, including positive airway pressure (PAP) plus a pharmacological agent who have heart failure or are using opioid analgesics. The investigators anticipate that findings will inform future clinical trials to improve care and quality of life among Veterans suffering from central sleep apnea, which remains difficult to treat using existing approaches.

Measure: Mortality Time: 28 daysMost patients in intensive care units (ICUs) experience severe sleep disruption. Sleep disruption and sleep alteration may have an influence on the ability to breathe spontaneously. But, the cause of altered sleep remains unknown.

Nocturnal respiratory muscle activity may be one of the potential factor which contribute to alter sleep in the ICU. Therefore, the aim of this study is to analyse the presence of NIM activation during the night and it's consequence in an ICU population with the same pathology (COVID 19 ARDS).
