Oxygen delivery through high-flow nasal cannulae increase end-expiratory lung volume and reduce respiratory rate in post-cardiac surgical patients.
TL;DR: This study suggests that HFNCs reduce respiratory rate and improve oxygenation by increasing both EELV and tidal volume and are most beneficial in patients with higher BMIs.

TL;DR: Subjective assessment of functional capacity should not be used for preoperative risk evaluation, and Clinicians should instead consider a measure such as DASI for cardiac risk assessment.

TL;DR: A DASI score of 34 represents a threshold for identifying patients at risk for myocardial injury, myocardia infarction, moderate-to-severe complications, and new disability, and a nested cohort analysis of the Measurement of Exercise Tolerance before Surgery study characterised the association of preoperative DASi scores with postoperative death or complications.
Oxygen delivery through high-flow nasal cannulae increase end-expiratory lung volume and reduce respiratory rate in post-cardiac surgical patients
TL;DR: In this paper, the effects of high-flow nasal cannulae (HFNC) on airway pressure (Paw) and end-expiratory lung volume (EELV) were investigated.

TL;DR: Objectively measured subclinical neurological injuries remain a concern in intermediate‐risk patients undergoing TAVI and are likely to manifest with early neurocognitive changes.
