Purpose: Although both the Henderson-Hasselbalch method and the Stewart approach can be used to analyze acid-base disturbances and metabolic and respiratory compensation mechanisms, the latter may be superior in detecting subtle metabolic changes.
Materials And Methods: We analyzed acid-base disturbances using both approaches in six healthy male volunteers practicing extreme voluntary hyperventilation. Arterial blood gas parameters were obtained during a breathing exercise consisting of approximately 30 cycles of powerful hyperventilation followed by breath retention for approximately 2 min.
Article Synopsis
- Disturbed circadian rhythms can lead to delirium in ICU patients, and bright-light therapy may help realign these rhythms to reduce delirium rates.
- A study was conducted in the Netherlands with 734 ICU patients, comparing high-intensity dynamic light application (DLA) against normal lighting to see if DLA could lower delirium incidence.
- Results showed no significant difference in delirium rates between the DLA group (38%) and the control group (33%), indicating that DLA alone is not effective and should be considered as part of a broader treatment strategy.
