Medical Equipment and Oxygen Therapy

This set of flashcards covers important medical equipment related to oxygen therapy and their functions, suitable for exam preparation.

Thorpe tube flowmeter

A low-pressure gas flowmeter that functions as a variable-orifice, measuring true flow at a constant pressure.

Pressure compensated flowmeter

A type of flowmeter that prevents changes in downstream resistance from affecting accuracy, calibrated at 50 psig.

Uncompensated flowmeter

A flowmeter calibrated at atmospheric pressure without restriction, causing accuracy issues with changes in downstream pressure.

Bourdon gauge

A low-pressure gas flowmeter used with an adjustable pressure reducing valve, not gravity dependent and ideal for patient transport.

Reducing valve

A device used to regulate or reduce gas pressure to a safe level for use.

Pin Index Safety System (PISS)

Safety system using pin holes to prevent incorrect gas connections for small cylinders.

American Standard Safety System (ASSS)

Safety system using threaded connections specific to each gas type for large cylinders.

Diameter-Index Safety System (DISS)

A safety system for low-pressure gas connectors used in various medical applications.

Oxygen concentrator

A device that enriches oxygen content in air, used in home settings for patients with respiratory needs.

High-flow nasal cannula (HFNC)

A device delivering high-flow oxygen with adjustable FiO2, providing humidified gas up to 60 L/min.

Nasal cannula

A low-flow oxygen delivery system that allows comfortable airflow for speaking and eating.

Simple mask

A low-flow mask covering nose and mouth, providing higher oxygen concentration but limiting eating and drinking.

Partial rebreather mask

A mask with no valves allowing oxygen to flow directly to the patient, useful for higher FiO2 ranges.

Non-rebreather mask

A mask equipped with valves to prevent exhaled air from entering the bag, providing high FiO2.

Venturi mask

A high-flow mask that delivers precise and fixed FiO2 by mixing oxygen with room air.

Bubble humidifier

A device to add humidity to low-flow oxygen systems, preventing drying of mucous membranes.

Large Volume Nebulizer

A device used for Bland Aerosol Therapy, providing humidified mist for inhalation of medication.

Small Volume Nebulizer

A device that converts liquid medication into a fine mist for inhalation directly into the lungs.

Stethoscope

An instrument used to auscultate internal sounds of a patient's body, including heart and lung sounds.

Blood pressure cuff

A device used to measure systolic and diastolic blood pressure, essential for patient assessment.

Oxygen tank factor

A measure indicating the amount of oxygen in the tank; for example, E cylinder: 0.28, H cylinder: 3.14.

High-Flow system

A system providing oxygen at high flow rates and adjustable FiO2 for critical respiratory conditions.

HomeFill System

Device to refill portable oxygen cylinders from a home concentrator, allowing patient mobility.
