Use of a plethysmography set-up for respiratory safety assessment.

Plethysmography is a widely used method in basic and preclinical research to study respiration.

Optoelectronic plethysmography can be used also in supine and prone positions.

Other complementary lung functions tests include plethysmography and nitrogen washout.

This measurement of blood flow to the male genitals is known as penile plethysmography.

Distal plethysmography also yields useful information about circulatory status in digits.

Body plethysmography may be used to measure:

Three tests were conducted using penile plethysmography.

Several penile plethysmography studies have shown high levels of arousal in heterosexual men to pornography showing sexual activity between women.

The movement of the belts is typically measured with piezoelectric sensors or respiratory inductance plethysmography.

Air plethysmography uses a similar principle but based on an air-filled long cuff, which is more convenient but less accurate.

Air plethysmography and the effect of elastic compression on the venous haemodynamics of the leg.

In bioimpedance plethysmography, the measure is sometimes based on pulsatile blood volume changes in the aorta.

Structured light plethysmography with pneumatachography.

Air plethysmography.

Impedance plethysmography is a non-invasive method used to detect venous thrombosis in these areas of the body.

Combining segmental systolic pressure and plethysmography to diagnose arterial occlusive disease of the legs.

In anesthetized plethysmography, lung resistance and dynamic compliance are measured directly because the subject is anesthetized.

RIP is the most frequently used, established and accurate plethysmography method to estimate lung volume from respiratory movements.

Myers notes, "Courts that have considered penile plethysmography generally rule that the technique is not sufficiently reliable for use in court."

Whole-body plethysmography is used to measure respiratory parameters in conscious unrestrained subjects, including quantification of bronchoconstriction.

Dual band respiratory inductance plethysmography was validated in determining tidal volume during exercise and shown to be accurate.

For example, researchers performing plethysmography studies in freely moving animals will use the RF analyzer that uses a single flow input.

In water plethysmography an extremity e.g. an arm is enclosed in a water-filled chamber where volume changes can be detected.

In order to measure RV precisely, one would need to perform a test such as nitrogen washout, helium dilution or body plethysmography.
