  2. Wiggers diagram - Wikipedia

    en.wikipedia.org/wiki/Wiggers_diagram

    Ventricular volume; Electrocardiogram; Arterial flow (optional) Heart sounds (optional) The Wiggers diagram clearly illustrates the coordinated variation of these values as the heart beats, assisting one in understanding the entire cardiac cycle. [1]

  3. Pulse - Wikipedia

    en.wikipedia.org/wiki/Pulse

    In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...

  4. Tidal volume - Wikipedia

    en.wikipedia.org/wiki/Tidal_volume

    Tidal volume (symbol V T or TV) is the volume of air inspired and expired with each passive breath. [1] It is typically assumed that the volume of air inhaled is equal to the volume of air exhaled such as in the figure on the right. In a healthy, young human adult, tidal volume is approximately 500 ml per inspiration at rest or 7 ml/kg of body ...

  5. Peripheral Arterial Tone - Wikipedia

    en.wikipedia.org/wiki/Peripheral_Arterial_Tone

    The PAT signal is a form of pulse wave amplitude measured by incorporating both a unified pressure field and a specific isosbestic wavelength.Applying a uniform pressure field around the measured surface releases arterial wall motion restriction, magnifies the dynamic range of the recorded signal, and prevents the distention of the veins distal to the site of pressure application.

  6. Time constant - Wikipedia

    en.wikipedia.org/wiki/Time_constant

    First order LTI systems are characterized by the differential equation + = where τ represents the exponential decay constant and V is a function of time t = (). The right-hand side is the forcing function f(t) describing an external driving function of time, which can be regarded as the system input, to which V(t) is the response, or system output.

  7. Residence time - Wikipedia

    en.wikipedia.org/wiki/Residence_time

    The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.

  8. Soliton (optics) - Wikipedia

    en.wikipedia.org/wiki/Soliton_(optics)

    With temporal solitons it is possible to remove such a problem completely. Linear and nonlinear effects on Gaussian pulses. Consider the picture on the right. On the left there is a standard Gaussian pulse, that's the envelope of the field oscillating at a defined frequency. We assume that the frequency remains perfectly constant during the pulse.

  9. Time of flight - Wikipedia

    en.wikipedia.org/wiki/Time_of_flight

    Time of flight of a light pulse reflecting off a target A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight , the round trip time of an artificial light signal, as ...
