Official Title: Prevention of Post Operative Hypoxia in the Post Anesthesia Care Unit Using Pulse Oximetry With Automated Verbal Prompts

Brief Summary: This study will evaluate the effectiveness of an automated voice prompting system on post operative hypoxia within the Postoperative Anesthesia Care Unit (PACU). This will be done to detect an improvement of the patient experience and provider care through a decrease in the number of peripheral capillary oxygen saturation (SpO2) monitor alarms via the patients own ability to follow the instruction and improve their SpO2 levels.

Detailed Summary:

The investigators will examine and observe the patient's stay in the PACU and utilize the pulse oximetry software and data to analyze the ability to evaluate the difference in patient oxygenation levels and supplemental oxygen use with automated verbal prompted monitoring versus a standard care control group. As well as determine if automated verbal prompted monitoring leads to less monitor alarms and subsequent improvement of subjective alarm fatigue and patient satisfaction with their care versus standard care.

The pulse oximeter will have a finger probe that will be attached to the patient's middle finger to read the patient's SpO2 levels. Each time the participant's pulse oximetry value declines to 93% or less, an automated verbal prompt, created via the software, will generate as a soft prompt. This will be followed up by a hard prompt if no improvement is seen in their oxygenation level after a period of time. A positive feedback elicitation will be given if the participant's saturation levels increase above 93%. This automated verbal prompt guidance will take place during the entirety of the investigational group's PACU stay.

Current Primary Outcome: Change in the frequency of a participant's SpO2 level falling below 87% [ Time Frame: Change from baseline up to 24 hours ]

SpO2 will be monitored using the standard pulse oximeter system


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Change between the study groups number of pulse oximetry alarms [ Time Frame: Change from baseline up to 24 hours ]
    SpO2 will be monitored using the standard physiologic monitoring system
  • Change between the study groups level of alarm fatigue [ Time Frame: Change from baseline up to 24 hours ]
    Number of participants reporting a decreased level of alarm noise
  • Change between the study groups level of postoperative care satisfaction [ Time Frame: Change from baseline up to 24 hours ]
    Number of participants reporting alarm noise affected their level of postoperative care satisfaction


Original Secondary Outcome: Same as current
