Secondhand Aerosol Exposure During Mechanical Ventilation With And Without Expiratory Filters: An In-Vitro Study, Arzu Ari, James B. Fink, Susan P. Pilbeam

Respiratory Therapy Faculty Publications

Background: Concerns have been expressed about risk of exposure to exhaled aerosols to ICU personnel.

AIM: To quantify amount of aerosol collected at the exhaust outlet of mechanical ventilators operated with and without filters in the expiratory limb.

Methods: Two categories of ventilators were tested: (1) Ventilators without Proprietary Filters: Servo-i (Maquet) and Galileo (Hamilton) and (2) Ventilator with proprietary filters: PB 840 (Covidien). Each ventilator was attached to a simple test lung and operated with VT 500 ml, RR 20 bpm, PIF 50 L/min, PEEP 5 cmH2O. Four separate doses of albuterol (2.5 mg/3mL) were administered via jet nebuliser …

Drug Delivery Interfaces: A Way To Optimize Inhalation Therapy In Spontaneously Breathing Children, Arzu Ari

Respiratory Therapy Faculty Publications

There are several different types of drug delivery interfaces available on the market. Using the right interface for aerosol drug delivery to children is essential for effective inhalation therapy. However, clinicians usually focus on selecting the right drug-device combination and often overlook the importance of interface selection that lead to suboptimal drug delivery and therapeutic response in neonates and pediatrics. Therefore, it is necessary to critically assess each interface and understand its advantage and disadvantages in aerosol drug delivery to this patient population. The purpose of this paper is to provide a critical assessment of drug delivery interfaces used for …

Complications Of Prone Positioning During Extracorporeal Membrane Oxygenation For Respiratory Failure: A Systematic Review, Rachel Culbreth, Lynda T. Goodfellow

Respiratory Therapy Faculty Publications

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is often used in patients with severe respiratory failure to improve oxygenation and survival. ECMO gives the lungs an opportunity to rest and recover. The addition of prone positioning therapy used concurrently with ECMO can further aid in optimizing alveolar recruitment and reducing ventilator-induced lung injury, ultimately resulting in fewer ICU admission days and improved overall survival. The objective of this review is to perform a systematic analysis of the complications reported with prone positioning and ECMO in the adult population and to briefly report on the patient outcomes in the studies. METHODS: PubMed, MEDLINE, …
