Combine physical activity with heart rate, respiration or light

VitaMove can be expanded with additional sensors to make it a highly flexible and versatile solution for many more ambulatory physiological monitoring applications. This requires a VMExG amplfier.  One VMExG amplifier can be connected to each recorder and can be used to measure respiration, light exposure or heart rate in combination with physical activity.

  • Measure ECG, EMG, EEG and/or EOG (2channels, 16bits, 256Hz)
  • Light sensor to measure exposure to environment light (requires VMExG amplifier)
  • RIP sensor to measure breathing rate (requires VMExG amplifier)

Measure ECG, HR & HRV

One VMExG amplfier contains 2 ExG amplifiers for:

  • ‘ECG RA-LL’: to derive Heart Rate and Variability (St. Dev.)
  • ECG LA-LL: only if Einthoven derivation is requested for display or..
  • ‘Fp2-M1’ and ‘Fp1-M1’: combined EEG/EOG for sleep stages and arousal

Measure ECG (2-3 lead) – ElectroCardioGram

Electrocardiography (ECG or EKG from the German Elektrokardiogramm) is a transthoracic (across the thorax or chest) interpretation of the electrical activity of the heart over a period of time, as detected by electrodes attached to the outer surface of the skin used to test the electrical activity of the heart. ECG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker).

VitaMove can be used as a conventional holter monitor for periods upto a week, but allows the caregiver to see what the patient or client was doing at the moment the event occurred. From the ECG the heart rate is derived. The heart rate is the number of heartbeats per unit of time, typically expressed as beats per minute (bpm). Heart rate can vary as the body’s need to absorb oxygen and excrete carbon dioxide changes, such as during exercise or sleep. The heart rate measurement is used by medical professionals to assist in the diagnosis and tracking of medical conditions. It is also used by individuals, such as athletes, who are interested in monitoring their heart rate to gain maximum efficiency from their training.  From the heart rate the heart rate variability (HRV) can be calculated to evaluate mental stress. Normal Ag, Ag/Cl pre-gelled disposable ECG electrodes are used.

Measure EEG – ElectroEncephaloGraphy

EEG records electrical activity along the scalp. In neurology, the main diagnostic application of EEG is in the case of epilepsy, as epileptic activity can create clear abnormalities on a standard EEG study. EEG can be a valuable tool for research and diagnosis, especially when millisecond-range temporal resolution (not possible with CT or MRI) is required.

Measure EOG -ElectroOculoGraphy

An EOG measures the resting potential of the retina. The resulting signal is called the electrooculogram. The main applications are in ophthalmological diagnosis and in recording eye movements. Usually, pairs of electrodes are placed either above and below the eye or to the left and right of the eye. If the eye is moved from the center position towards one electrode, this electrode “sees” the positive side of the retina and the opposite electrode “sees” the negative side of the retina. Consequently, a potential difference occurs between the electrodes. Assuming that the resting potential is constant, the recorded potential is a measure for the eye position.

Measure EMG – ElectroMyoGraphy

EMG is a technique for evaluating and recording the electrical activity produced by skeletal muscles. An EMG detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, recruitment order or to analyze the biomechanics of human or animal movement.

Respiratory Inductance Plethysmography (RIP)

Respiratory Inductance Plethysmography (RIP) is a method of evaluating pulmonary ventilation by measuring the movement of the chest and/or abdomen. A RIP sensor can be added to the VitaMove system to  measure breathing rate of chest and/or abdomen excursion. RIP has been used in many clinical and academic research studies in a variety of domains including polysomnographic (sleep), psychophysiology, psychiatric research, anxiety and stress research, anesthesia, cardiology and pulmonary research (asthma, COPD, dyspnea).

Environment light exposure

The light sensor can be added to the VitaMove system to measure exposure to light (time and amount). This can be used to check if people get enough exposure to sunlight, follow night shift workers and so on. Logarithmic sensor (from -2 to +5 LogLumen).
