7-4. Pneumoplethysmograph
With the PV-21, Smartdop senses volume changes in a limb or digit by measuring the pressure changes in a recording cuff. “How to use pneumoplethysmograph” is described in this section. Built-in cuff inflator works when INFLATOR in menu mode is ON to inflate cuff. See “§ 7-4-4. PV Mode Setting - INFLATOR” for details.
7-4-1. PV (Pneumoplethysmography) Probe Assemblies
Model PV-21
DC Coupling: Measurement of maximum venous outflow
7-4-2. PV - Measurement of Maximum Venous Outflow
Purpose
Because deep venous occlusion cannot be diagnosed reliably on the basis of presenting signs and symptoms, pain and swelling being frequently due to other causes, objective screening tests are of value in confirming or ruling out suspected venous obstructions in the lower extremities. The test consists of first inducing temporary venous pooling by means of a constricting thigh cuff followed by measurement of the rapidity of emptying when the constricting cuff is suddenly vented. Measurement of maximum venous outflow is frequently employed as an adjunct to Doppler venous compression studies.
Preparation
(1) Connect the PV probe assembly (PV-21) the probe connector #1 or #2 of the main unit,
and turn it on.
(2) Make sure Mode 2 LED (DC mode) illuminates. If not, press MODE button to select
Mode 2 for DC mode.

Examination Procedure
(1) Place the patient in supine position with the leg and hip rotated outward. Use pillows to
support the leg and hip. It is important that the patient is comfortable and relaxed.
(2) Wrap a wide occluding cuff at mid-thigh and a sensing cuff at mid-calf.
(3) Connect a 3-way stopcock to the inlet of PV probe. Interconnect the stopcock, tubing,
cuff and sphygmomanometer as shown below.
(4) Turn the stopcock so that air is routed from the sphygmomanometer to the sensing cuff
at mid-calf.
(5) Inflate the sensing cuff to 40 mmHg. Wait 10 seconds to allow time for settling and
deflate the cuff to 15 mmHg.
(6) Turn the stopcock so that it blocks sphyg and routes cuff pressure to the PV probe.
(7) Disconnect the sphyg from the stopcock and attach it to the occluding cuff at the thigh.
If INFLATOR is ON, connect occluding cuff to inflation inlet of Smartdop instead of
sphyg with a tubing.
(8) Press PRINT button to begin the measurement process.
(9) Inflate the occluding cuff at the thigh to at least 60
mmHg. If INFLATOR is ON, press INF instead to
inflate cuff. Pressures in sensing cuff are plotted on
the screen. The graph will indicate a gradual
increase in waveform amplitude signifying that
venous outflow is blocked by the occluding cuff.
(10) After 90 seconds, disconnect the sphyg from the
occluding cuff. The pressures on the screen will
drop back to the baseline.

8. Technical Information
8-1. Principles
Model Smartdop 30EX is designed to obtain various blood flow velocity through the ultrasound which is transmitted from probe to patient body and is reflected by the blood (hemocyte, etc.). The unit amplifies the high frequency oscillation output and then supplies it to the transmitter transducer. It is converted to ultrasound by the transducer and the ultrasound is transmitted to external objects. The ultrasound moves straight through biophysical object, and is reflected by the moving object (blood flow, fetal heartbeat etc.). The reflected ultrasound is received by the receiving transducer and is converted into electric signals again.
The converted signals are amplified and then detected. After removing unnecessary noise from the signals and improving S / N ratio at the filter circuit, the Doppler shift signals are amplified and are converted to audible sounds through a speaker or a headset. Simultaneously, the Doppler shift signals are applied to the CPU and converted to blood flow velocity waveform signals which can be displayed and printed.
On the ARM / LEG and TOE pressure modes, the blood pressure cuff is wrapped where the blood pressure is taken and the probe is put on the lower extremity artery by the operator. Before the inflation, the peak amplitudes of the blood flow signals should be stable. As the cuff pressure goes up by activating the inflation pump, the blood vessel is being pressed and the peak amplitudes become lower. The CPU finds the point where the peak amplitudes are below the threshold and waits until the cuff pressure is inflated an estimated 30 mmHg above the point. Then the CPU deactivates the inflation pump and lets the cuff pressure go down at a moderate rate until the first blood flow signal that exceeds the threshold is detected. The cuff pressure at the first signal is the systolic pressure. After confirming a return of the rhythmical blood flow signals, the CPU opens the air valve to dump the cuff pressure and displays the systolic blood pressure on the LCD.

Portable and mobile RF communications equipment should be used no closer to any part of the Smartdop 30EX, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter. Recommended separation distance d = 1.2√P
d = 1,2√P 80 - 800 MHz d = 2,3√P 800 MHz - 2,5 GHz
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Field strength from fixed RF transmitters, as

determined by an electromagnetic site survey, a should be less than the compliance level in each frequency range. b Interference may occur in the vicinity of the equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Smartdop 30EX is used exceeds the applicable RF compliance level above, the Smartdop 30EX should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Smartdop 30EX.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
