The Effect Of Using Different Aerosol Devices And Masks On Aerosol Deposition During Noninvasive Positive Pressure Ventilation In An Adult Lung Model, Maher M. Alquaimi

Respiratory Therapy Theses

Introduction: Although patients with an acute increase in airflow resistance may require aerosol therapy and noninvasive positive pressure ventilation (NIPPV), the efficiency of different aerosol devices and masks during NIPPV is not well understood. The purpose of this study was to determine the efficiency of a jet nebulizer (JN), a vibrating mesh nebulizer (VMN) and a pressurized metered-dose inhaler (pMDI) and three different masks during NIPPV.

Method: An in vitro lung model consisted of the upper airway of an adult teaching manikin with a collecting filter at the level of the bronchi attached to a passive test lung. NIPPV was …

Efficiency Of Aerosol Therapy Through Jet Nebulizer, Breath-Actuated Nebulizer, And Pressurized Metered Dose Inhaler In A Simulated Spontaneous Breathing Adult, Abdullah Alqarni

Respiratory Therapy Theses

BACKGROUND: Aerosol therapy using albuterol is one of the most prescribed asthma treatments. The most frequently used methods of aerosol delivery are pneumatic jet nebulizer (JN), pressurized metered-dose inhaler (pMDI), and breath-actuated nebulizer (BAN). Choosing among these devices is usually not based on thorough comparison of efficiency or cost. We compare the efficiency of these three devices using a spontaneously breathing adult model.

METHODS: We connected each aerosol generator—JN, BAN, or pMDI with a valved holding chamber (VHC)—to the face of an adult teaching manikin. Below the bifurcation, an elbow adaptor was connected to a corrugated tube and …

Cost-Benefit Analysis Of A Dosimetric Nebulizer Using Circulaire And Atraditional Vixone Nebulizer, Nwakaego C. Okere Ms

Respiratory Therapy Theses

Aerosol administration via small-volume nebulizers are still being used by selected patient-population. In the economic market, several nebulizer designs have become available, with each incorporating unique features that will potentially establish it as the preferred choice in aerosol delivery. With the continuous rising cost of health care services, clinicians are faced with the task of identifying opportunities for cost reduction in respiratory care. PURPOSE: The purpose of this study was to conduct a cost-benefit analysis of dosimetric nebulization using the Circulaire system and the traditional VixOne nebulizer. The desired outcome was to elevate awareness of the potential impact of the …

The Independent Effect Of Three Inline Suction Adapters And Lung Compliance Change On Amplitude And Delivered Tidal Volume During High Frequency Oscillatory Ventilation In An Adult Patient With Ards: Bench Model, Shreya Thacker

Respiratory Therapy Theses

Introduction: The use of high frequency oscillatory ventilation is increasing in treatment ofacute respiratory distress syndrome over the past decade. The technique of HFOV of ventilatingthe lungs at volumes less than the anatomical dead space calms the clinical concerns surroundingventilating stiff ARDS lungs with high pressures and volumes. This largely reduces theprobability of barotraumas and/or atelectrauma.

Purpose: The study was on an in vitro bench model that answered the following researchquestions: 1. The effect of three inline closed suction adapters on delivered tidal volume duringHFOV with varying lung compliance 2. The effect of varying compliance on the amplitudedelivered by HFOV; …
