Changes in patient populations, along with economic and practical considerations, have led to an overall increase in patient acuity on the general care floor (GCF). Despite the presence of higher risk patients, current GCF surveillance is often limited to isolated spot checks of core vital signs, such as heart rate, respiratory rate, blood pressure and temperature, with such observations often limited to every 4 hours, which leaves patients unmonitored 96% of the time.1 Therefore, these patients may be placed at increased risk for respiratory compromise.
Changes in respiratory vital signs that accompany respiratory compromise often precede in-hospital deterioration and are associated with increased mortality due to the high likelihood of decompensation into respiratory insufficiency and failure, as well as respiratory arrest. 2,3,4,5
Moreover, many in-hospital declines may be preventable with better respiratory monitoring and early intervention.6,7,8 Continuous monitoring of respiratory function and patient evaluation for respiratory insufficiency, arrest and failure can alert medical professionals to conditions which could lead to adverse events. Therefore, implementing better strategies for prevention, monitoring for and management of respiratory abnormalities in patients could lead to improved patient outcomes and decreased costs.
Incidence of respiratory adverse events in moderate to deep procedural sedation is often underestimated, still reported in published clinical studies16 and its consequences may, even if rarely, lead to death.16
The outcomes pledge program by Medtronic will help you measure the incidence of adverse events in your own setting, with your own clinical team and your own protocols and assess the impact of capnography monitoring on the prevention of such events.
