Background: For those with Obstructive Sleep Apnea (OSA), the most effective therapy is continuous positive airway pressure (CPAP). CPAP uses positive airway pressure to keep the patients' respiratory passages open while they sleep (or are awake and breathing normally). End-expiratory alveolar pressure that exceeds ambient pressure is known as a "positive end-expiratory pressure" (PEEP). PEEP is created by CPAP, which maintains a predetermined pressure during the whole breathing cycle, including inhalation and exhalation. It has been shown to lower daytime exhaustion, cardiac risk factors, as well as blood pressure. Objective: The primary therapy for OSA is CPAP. CPAP was evaluated in this study to see if it reduced blood pressure in OSA patients. Research on CPAP and blood pressure in various subgroups of people was analyzed specifically for this study. Methods: Research was carried out through PubMed, Google scholar and Science direct using the terms [Continuous positive airway pressure And Positive end-expiratory pressure OR Obstructive Sleep Apnea]. References from relevant literature, including all identified research and reviews, were also evaluated by the authors, although only studies published between December 2007 and June 2021 were included. Conclusion: Although the overall impact of CPAP on blood pressure is minimal, even modest reductions in blood pressure may benefit in the prevention of cardiovascular events. This impact on those with uncontrolled hypertension merits further investigation. Variability in blood pressure response to CPAP therapy gives an opportunity for more study on this topic. Constant CPAP use has long been associated with an increased risk of hypertension.
Background: It's not uncommon for people to suffer obstructive sleep apnea syndrome (OSAS); 2%-25% of the general population are affected. However, OSAS is common in those who have undergone elective surgery. Patients with collapsing upper airway have an increased risk of surgical complications when under sedation and/or anesthesia. To effectively treat individuals with OSAS, it's critical to rapidly identify them.Objective: In this review, the epidemiology of OSAS in postoperative patients was examined. We emphasized the significance of anaesthesia, sedation, opioids, while describing why these patients have a higher postoperative complications' risk. Further, we addressed the preoperative identification and perioperative management of these individuals.Methods: Research was carried out through PubMed, Google scholar and Science direct using the terms OSAS, Perioperative complications, Respiratory problems, and continuous positive airway pressure (CPAP). References from relevant literature, including all identified research and reviews, were evaluated (only studies published between July 2003 and January 2022 were included). There were no reliable sources of interpretation for documents written in any language other than English. All but the most important scientific papers had been omitted: not available as a complete written text such as a transcript of a conversation or a formal paper such as a conference abstract or thesis. Conclusion:Opioids, sedation, and anesthesia have been proven to aggravate sleep apnea during the perioperative phase, which may raise the risk of perioperative problems. It is essential to identify these individuals before surgery in order to take the necessary precautions during their perioperative care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
