  • Objectives

    Understand the challenges of predicting cardiorespiratory compromise, and how to address them1

    Learn potential benefits of continuous monitoring on the general care floor to improve outcomes2

    Identify who to monitor as well as what and how to monitor3

    Translate expanded knowledge of cardiorespiratory compromise into improvements in practice and patient monitoring protocols – integrate better in-patient monitoring on the general care floors

  • The Scope of the Problem

    Cardiorespiratory complications are the most common cause of 30-day postoperative mortality[4]

    Unplanned ICU admissions may have respiratoryindication in 17-47% of cases particularly postoperative pulmonary complications[5-8]

    AHRQ rated postoperative respiratory failure as the fourth most common patient safety event[4]

    Hypotension and hypoxemia on the general care floor (GCF) is common, profound, prolonged and cannot be reliably predicted [1,2]

    49% of cardiac arrest on GCF had a respiratory cause – higher than ICU[3]

    WHAT TO MONITOR? CARDIORESPIRATORY

    Available evidence has shown that cardiorespiratory

    compromise is common, goes undetected and is largely

    unpredictable

    HOW TO MONITOR? CONTINUOUS (AUTOMATED)

    Continuous monitoring of all patients on the regular floor appears to be the answer to detecting cardiorespiratory

    compromise early

    WHO TO MONITOR? EVERYONE

    APSF recommends continuous monitoring for

    all patients receiving opioid therapy in the postoperative

    period, especially when supplementary oxygen is

    administered

    BETTER MONITORING? YES

    Continuous monitoring of capnography and oximetry can provide clinicians with

    early identification of evolving Respiratory

    Compromise, allowing for early intervention that may

    prevent tragic consequences
