Respiratory care
-
Respiratory compromise is a common and potentially dangerous complication of patients admitted to general care units of hospitals. There are several distinct and disparate pathophysiologic trajectories of respiratory deterioration that hospitalized patients may suffer. Obstructive sleep apnea and preexisting cardiopulmonary disease increase the risk of respiratory failure after major surgery. ⋯ Early warning systems that utilize analysis of intermittently collected vital signs may result in earlier recognition of clinical deterioration. Continuous monitoring of oximetry and capnography may allow the detection of pathophysiologic abnormalities earlier in patients in general care units, but the evidence for improved clinical outcomes remains weak. Increased monitoring may lead to increased monitor alarms that can have negative effects on patient care.

Monitoring respiratory values such as breathing frequency, minute ventilation, breathing effort, and dyspnea are common in acute care. There is evidence that accurate monitoring and interpretation of these values leads to early identification and treatment of impending respiratory failure. ⋯ Many questions remain regarding how to most efficiently and effectively monitor other respiratory values, like noninvasive minute volume and breathing effort, as well. As technology continues to improve alongside the understanding of respiratory physiology, clinicians are able to apply basic clinical assessment skills and technology together to improve patient safety and outcomes.
