Physiological monitoring is the crucial aspect of the mouse imaging which ensure the animal health during imaging examination. It also use robust measurement with the parameters but incur some challenges because of the size of the animal. Luckily, there are now many sensors available on the market and fully integrated systems that facilitate this. Many of them compatible with several imaging modalities of the leading manufacturers and integrate software to record various physiological parameters.
Components for the physiological monitoring
Central Station
Most of the modern physiological monitoring sends the output to the central monitoring station to evaluate or display. Besides, it allows the integration of physiological data from patient’s monitors into the electronic hospital medical record, using the right health care standards.
Bedside monitor
A bedside monitor continuously displays the physiological data on a CRT, LCD, or LED monitor as the individual data rows on the physiological criteria selected alongside the timeline. These physiological criteria typically include respiratory rate, heart rate, pulse oximetry, and blood pressure.
Telemetry receiver and transmitter
The sensors are positioned on a patient and ensure the physiological data is transmitted to a bedside monitor. Multiple sensors are often needed. The ambulatory telemetry is attained using Wi-Fi compatible models, powered by battery, used by the patient to transmit the data over the connection of wireless data.
Advantages
With physiological monitoring, it allows early detection of vital functions and makes employees aware of critical situations. Physiologists use audio and visual alarms to monitor doctors when changing the patient’s condition, which may need immediate intervention. Constant monitoring of the patients in a hospital is a valuable tool for providing more information about the diagnosis and treatment of patients, nursing, and medical staff. They allow medical personnel to be monitored continuously, even when it comes to other patients or activities.
Disadvantages
The purpose of physiological monitoring is to prevent respiratory and cardiac arrest, generating an alarm to alert doctors about signs of instability. Alarm algorithms are generally set up to maximize sensitivity and sacrifice specificity to minimize the likelihood that monitors can miss deterioration signs. Because of this, monitors generate a large number of false alarms which do not guarantee clinical intervention. Most of the time, high alarm rates interfere with the patient care by disabling doctors’ alarms.
Applications
Physiological monitoring leads to the formation of smart devices that create a personal network via wireless transmission. All data may be sent to a computer so that the data can be monitored remotely in real-time. These smart devices also have advantages and the disadvantages. The benefits of these devices include the early detection of significant sign deterioration, better communication between patients and family members, family safety, and the preservation of patients’ dignity and independence. They also help to monitor soldiers on the battlefield and improve athletic conditions.
Disadvantages include expensive device costs, physiological monitors in the hospital, and false alarms. These devices need to be continuously updated to ensure that patient information is displayed correctly on the device. Incorrect information can lead to incorrect diagnoses and inadequate patient care.
