Physiologic monitors monitor vital sign parameters and inform clinicians of changes in a patient's condition through the use of alarms. They consist of multiple components, including a central station, bedside monitors, and ambulatory telemetry transmitters and receivers. Recently, smart devices that can be attached a patient’s body or even integrated into their garments have also been developed.
Advantages
Advantages of physiological monitors:
- Allow early detection of vital sign deterioration
- Alert responders to critical situations
- Enhance connectedness among patients and loved ones, providing reassurance to family and maintaining dignity and independence for patients
- Identify correlations between health and lifestyle
- Battlefield monitoring of soldiers
- Improve sports related conditioning
- Provide providers with transformative real time physiologic data
- Expand health care access to rural areas and developing countries where cellular access is often the only communication method available
Disadvantages
To minimize the probability that monitors will miss signs of deterioration, alarm algorithms and parameters are often set to maximize sensitivity, sacrificing specificity. As a result, monitors generate large numbers of nonactionable alarms, alarms that are either invalid and do not accurately represent the physiologic status of the patient or are valid but do not warrant clinical intervention. In national surveys of healthcare staff, respondents report that high alarm rates interrupt patient care and can lead clinicians to disable alarms entirely. Recent research has supported this, demonstrating that nurses exposed to higher numbers of alarms have slower response times to alarms. In an attempt to mitigate safety risks, The Joint Commission issued recommendations for hospitals to (a) establish guidelines for tailoring alarm settings and limits for individual patients, and (b) identify situations when alarms are not clinically necessary.
Alert fatigue
Applications
Smart devices can create a personal network with wireless transmission of physiologic monitoring. Any data can be sent to computer, allowing remote monitoring of real time data. There are also advantages and disadvantages to these smart devices. Advantages for these devices include early detection of vital sign deterioration, enhanced connectedness among patients and loved ones, providing reassurance to family and maintaining dignity and independence for patients, and providing clinicians with transformative real time physiologic data. In addition, they also allow for battlefield monitoring of soldiers and improvement in sports related conditioning. Disadvantages include the high expense of the devices, and similar to hospital physiologic monitors, sensitivity of these devices can also be a factor. These devices must be constantly updated in order to make sure that patient data is being displayed on the device accurately. Improper data can lead to improper diagnoses, which also leads to improper care for a patient.
Two such devices currently being developed and tested include the LifeGuard wireless physiologic monitor and the HealthGear real time physiologic monitoring system.
Lifeguard
The LifeGuard system is being developed by NASA to monitor the health of astronauts during space flights and extravehicular activities. Capabilities of the LifeGuard include:
- Heart rate
- Systolic and diastolic blood pressure
- Activity, (3-axis acceleration)
- ECG, (2 channels)
- Temperature
- Respiration rate
- Pulse oximetry
HealthGear
The HealthGear system is being developed by Microsoft, it is designed to be integrated into clothing and not only collects real time data but also performs algorithmic interpretation of the data for detecting sleep apnea episodes.
- Heart Rate
- Respiration rate
- Pulse oximetry
- Plethysmographic signal
- Modular format to allow addition of additional components
