Aerosol and Humidity in Respiratory Care

A set of 50 vocabulary flashcards drawn from lecture notes on aerosol therapy and humidity in respiratory care.

Air entrainment nebulizer

A device that delivers aerosolized medication using sterile water for inhalation.

Venturi mask

A mask that delivers a precise concentration of oxygen via air-entrainment.

Tracheostomy collar

An aerosol interface that fits over the tracheostomy site.

Aerosol mask

A device used to deliver aerosolized medication to the mouth and nose.

Brigg's T-adaptor

A connector that allows for aerosol medication delivery while minimizing circuit interruption.

Passive humidity

Humidity provided without active heating, often using heat and moisture exchangers.

Active humidity

Humidity that may be heated or unheated, actively maintaining temperature.

Humidity deficit

The difference between the amount of moisture in the air and what the air can hold.

Bubble humidifier

A device that creates bubbles in water to increase humidity for inhaled air.

Therapeutic effect

The beneficial outcome of delivering medication through aerosol.

MDI

Metered-dose inhaler, a device used to deliver medication in aerosol form.

DPI

Dry powder inhaler, a device used for inhaling powdered medication.

SVN

Small volume nebulizer, used to deliver aerosols with medications.

HHN

Handheld nebulizer, similar to SVN, used for delivering aerosolized medications.

Breath hold

The act of intentionally holding one's breath to allow better deposition of medication.

Continuous aerosol

A steady delivery of aerosolized medication over a period of time.

Temperature probe

A device used to monitor and adjust the temperature in aerosol delivery systems.

Oxygen analyzer

A tool used to measure the concentration of oxygen in delivered air.

HME

Heat and Moisture Exchanger, used for passive humidity during ventilation.

Wick humidifier

A device that utilizes a wick to absorb water and provide humidity.

Passover humidifier

A humidifier that passes gas over a water reservoir to add humidity.

Intermittent medication delivery

Delivery of medication in intervals rather than continuously.

Aerosolized medication

Medication delivered in aerosol form for inhalation.

Patient interface

The device connecting the patient to the delivery system for medication.

Facial trauma

Injury to the face that may impact airway management.

Post-extubation stridor

A high-pitched wheezing sound after removal of an endotracheal tube.

Tonsilectomy

Surgical removal of the tonsils often affecting airway patency.

Noninvasive ventilation (NIV)

A method of delivering respiratory support without intubation.

Continuous feed humidifier

A humidifier that continuously supplies sterile water for inhalation.

Condensation rainout

Water build-up in the airway circuit due to temperature differences.

Heater or heating plate

Component of the humidifier that warms the water to provide active humidity.

Long bore tubing

Large diameter tubes used for high-flow oxygen delivery.

Burns and facial trauma

Conditions that may require specialized aerosol delivery.

Oxygenation during NIV

Maintaining adequate oxygen levels during noninvasive support.

Dosage for SVN

Specific medication amounts delivered via small volume nebulizers.

Breaking the circuit

Disconnecting the ventilation circuit, potentially reducing pressure.

Valve T-adaptor

A device that allows aerosol medication delivery without interrupting airflow.

Temperature maintenance

The importance of controlling humidity and temperature in ventilation,

Aerosol heater

A device that preheats the aerosol before delivery to the patient.

Humidity for ventilation

The need for adequate humidity in patients receiving mechanical ventilation.

Critical care airways

Artificial airways commonly used in critically ill patients: ET tube and trach tube.

Medication deposition

The process by which aerosolized medication settles in the lungs.

Therapeutic aerosols

Aerosols specifically formulated for medical purpose and patient treatment.
