The primary objective of this prospective, blinded observational study is to correlate assessment of sedation and respiratory status with capnography and pulse oximetry monitoring in hospitalized adult medical and trauma patients receiving patient-controlled analgesia (PCA) or nurse administered intravenous opioids for acute pain. Nursing assessment of respiratory status and sedation level will be correlated with capnography and pulse oximetry values as technology-supported monitoring to identify respiratory depression and opioid-induced sedation. The secondary objective is to identify capnography and pulse oximetry values that correlate with respiratory decompensation and opioid-induced sedation in medical and trauma patients on the general care floor.

Hypoventilation [ Time Frame: Change from baseline measurement observed within 60 minutes after opioid aministration ]
Continuous respiratory monitoring using capnography will be performed for collecting data of end-tidal carbon dioxide (etCO2)
Secondary Outcome Measures :
Hypoxemia [ Time Frame: Change from baseline measurement observed within 60 minutes after opioid administration ]
Continuous respiratory monitoring using pulse oximetry will be performed for collecting data of oxygen saturation (SpO2)
Other Outcome Measures:
Sedation [ Time Frame: Change from baseline assessment observed within 60 minutes after opioid administration ]
Sedation assessment will be preformed using the Moline Roberts Pharmacologic Sedation Scale in which sedation levels of 1, 2, 3, 4, 5, 6 are assessed where increasing numbers represent increasing levels of Sedation and sedation levels 3 or 4 or 5 or 6 indicate unintended opioid-induced sedation for the purpose of this study
Sedation [ Time Frame: Change from baseline assessment observed with 60 minutes after opioid administration ]
Sedation assessment will be preformed using the Pasero Opioid-Induced Sedation Scale in which sedation levels of S, 1, 2, 3, 4 are assessed where "S" represent normal sleep and increasing numbers represent increasing levels of Sedation and sedation levels 3 or 4 indicate unintended opioid-induced sedation for the purpose of this study
