The rise of ward monitoring: opportunities and challenges for critical care specialists

Excerpt

Many hospitals have implemented rapid response teams (RRTs) for rescue interventions outside the ICU. The outcome impact of RRTs is still a matter of debate but there is a consensus regarding the fact that timely detection and notification of clinical deterioration (aka the afferent limb) is a key determinant of success [1, 2]. To improve the detection of clinical deterioration, multiple monitoring systems have recently been developed for the wards. They include wireless pulse oximeters, adhesive patches containing electrodes, accelerometers, thermistors or piezoelectric sensors, and bioimpedance necklaces [3‐5]. These new tools enable the continuous monitoring of heart rate (or pulse rate), ECG (one or more leads), respiratory rate, SpO₂, peripheral perfusion, axillary temperature, and the detection of changes in thoracic fluid content and blood pressure. The rise of ward monitoring creates opportunities and challenges for critical care specialists that are discussed in this article. …
