Respiratory Inductance Plethysmography (RIP) is a method of evaluating pulmonary ventilation by measuring the movement of the chest and abdominal wall.

Accurate measurement of pulmonary ventilation or breathing often requires the use of devices such as masks or mouthpieces coupled to the airway opening. These devices are often both encumbering and invasive, and thus ill suited for continuous or ambulatory measurements. As an alternative RIP devices that sense respiratory excursions at the body surface can be used to measure pulmonary ventilation.

A Respiratory Inductance Plethysmograph consists of two sinusoid wire coils insulated and placed within two 2.5 cm (about 1 inch) wide, lightweight elastic and adhesive bands.

Torakografia – metoda zapisywania ruchów klatki piersiowej za pomocą torakografu. Torakograf składa się z części odbierającej – sprężystego mieszka, mocowanego za pomocą taśm owiniętych wokół klatki piersiowej na plecach, połączonego przewodem z częścią zapisującą – bębenkiem Mareya z pisakiem i kimografu. Wykonuje się pomiary dla spokojnego oddechu, po wysiłku fizycznym, po hiperwentylacji i po bezdechu. Wynik badania w postaci wykresu (torakogram) przedstawia amplitudę i częstość ruchów klatki piersiowej.

The term TOCOGRAPH is also in use in relation to fetal heart tocographic (CTG) monitoring; tocographic and EHG recording of a patient with preterm uterine contractions

We
would go further and suggest that anticipation and thus
prevention of this complication can be achieved by the use
of a simple ink-writing external tocograph.' Such an instrument
causes no discomfort to the patient, produces a graphic
record sufficiently accurate for all practical purposes of the
frequency and strength of the uterine contractions, and, more
important, effectively indicates any tendency to incomplete
relaxation between contractions

the labor is continuously monitored by cardio-tocograph
