Medical devices, generally, have been unique units, so that a typical hospital room in an intensive care ward hosts a big number of stand-alone devices, each one with its own user interface. Nowadays, these devices have some connection mechanisms, but the goal is to go beyond the simple connectivity that permits only the reading of the measured value on a computer monitor, to move towards a more complex...
In neonatal intensive care units many important vital signs are continuously measured in order to have a full monitoring of the patient. To this aim, cardiac rate, respiration activity, blood saturation, body temperature are extensively collected by contact sensors. Temperature, particularly in preterm infants, is a key quantity to be assessed if the aim is to verify the patient development and is/her...
Pulse oximetry (PO) is a measurement method used to determine the percentage of blood that is loaded with oxygen (oxygen saturation). It is an easy-to-sue, safe, convenient, inexpensive, painless and noninvasive measurement method for the assessment of oxygen content in the circulatory system and it also allows to measure the pulse frequency (coincident to the heart rate). It is frequently asses in...
Many important vital signs need to be measured on preterm patients when they are recovered in intensive care units: cardiac rate, respiration activity, blood saturation, temperature. The later is, in particular, a key quantity to assess when the aim is to verify if the patient has fully developed the capacity to regulate his/her temperature. Presently, the procedure followed by clinicians is based...
Heart Rate (HR) and Respiration Rate (RR) are considered among the most useful biomedical signals to be observed from a subject in order to evaluate his/her health conditions. HR and RR are routinely monitored in patients recovered in hospitals and eventual variations of these quantities need to be measured and reported. Today HR and RR are measured with standard methods: electrocardiography (ECG)...
In this paper, a novel contactless measurement method for the assessment of the thermoregulatory abilities of preterm infants is proposed. It is based on the use of an infrared (IR) thermo-camera allowing precise, multipoint and contactless measurement of the skin temperature of the preterm patient. The method proposed has been designed to verify the ability of the preterm patients to correctly operate...
At present there is a clear need for non-contact monitoring of the physiological signs of the patients. The system proposed in this paper aims to measure the heart rate of neonatal infants without any direct contact with the patient. The solution proposed is based on the use of standard, low-cost and commercially available digital webcamera by which it has been possible to observe defined portions...
The continuous monitoring of patients recovered in intensive care units is a mandatory tasks for clinicians in order to check conditions and effects of therapies. Among the many signals and quantities observable, the ones related to the heart and particularly the lung's activity are of primary interest. Today the majority of the measurement methods used for the assessment of the respiration rate are...
Standard instrumentation for the assessment of the respiration rate is largely used in medicine. Spirometers, textile-based capacitive sensors or photopletismography are all contact devices used for such aim; the main drawback in their use is the necessity to have a direct contact between the instrument and the patient, which in some cases can limit the use of such devices. In this paper, we present...
