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, …

Use Of Aerosol Drug Therapy In Pulmonary Rehabilitation, Arzu Ari

Respiratory Therapy Faculty Publications

Clinical applications of pulmonary rehabilitation are patientfocused and consist of individualized therapies such as aerosol drug therapy, airway clearance, chest physical therapy, exercise, and patient education. Devices that are used in aerosol drug delivery are divided into the following 3 categories: (1) small volume nebulizers, (2) metered-dose inhalers, and (3) dry powder inhalers. Although these devices are commonly used for the treatment of patients with pulmonary diseases, there are a limited number of objective studies on the physiologic and clinical effects of aerosol drug therapy on pulmonary rehabilitation. The purpose of this review paper is to explain all the devices …

Performance Comparisons Of Jet And Mesh Nebulizers Using Different Interfaces In Simulated Spontaneously Breathing Adults And Children, Arzu Ari, Armèle Dornelas De Andrade, Meryl M. Sheard, Bshayer R. Alhamad, James B. Fink

Respiratory Therapy Faculty Publications

Background: Different types of nebulizers and interfaces are used for the treatment of adults and children with pulmonary diseases. The purpose of this study was to determine the efficiency of a mesh nebulizer (MN) with a proprietary adapter and a jet nebulizer (JN) under different configurations in adult and pediatric models of spontaneous breathing. We hypothesize that delivery efficiency of JN and MN will differ depending on the interface used during aerosol therapy in simulated spontaneously breathing adult and pediatric models. While we expect that aerosol delivery with JN will be less efficient than MN, we also hypothesize that lung …

Jet, Ultrasonic, And Mesh Nebulizers: An Evaluation Of Nebulizers For Better Clinical Outcomes, Arzu Ari

Respiratory Therapy Faculty Publications

For over a century, nebulizers have been commonly used to deliver aerosolized medications in the treatment of patients with pulmonary diseases. They are the aerosol device of choice when patients can not coordinate inhalation and actuation needed for the use of the pressurized metered-dose inhalers (pMDIs) or are not able to provide the necessary inspiratory flow required by the dry powder inhaler (DPI) for effective aerosol drug delivery. Three types of nebulizers exist: (1) jet nebulizers, (2) ultrasonic nebulizers, and (3) mesh nebulizers. The purpose of this paper is to explain the types of nebulizers available on the market and …

Inhalation Therapy In Patients Receiving Mechanical Ventilation: An Update, Arzu Ari, James B. Fink, Rajiv Dhand

Respiratory Therapy Faculty Publications

Incremental gains in understanding the influence of various factors on aerosol delivery in concert with technological advancements over the past 2 decades have fueled an ever burgeoning literature on aerosol therapy during mechanical ventilation. In-line use of pressurized metered-dose inhalers (pMDIs) and nebulizers is influenced by a host of factors, some of which are unique to ventilator-supported patients. This article reviews the impact of various factors on aerosol delivery with pMDIs and nebulizers, and elucidates the correlation between in-vitro estimates and in-vivo measurement of aerosol deposition in the lung. Aerosolized bronchodilator therapy with pMDIs and nebulizers is commonly employed in …

Aerosol Therapy For Ventilator-Dependent Patients: Devices, Issues, Selection & Technique, Arzu Ari

Respiratory Therapy Faculty Publications

Aerosol devices have been used to administer inhaled medications since the invention of modern mechanical ventilators. Although many new aerosol devices are available for ventilator-dependent patients, successful aerosol therapy still depends on thorough clinician knowledge of aerosol devices and their proper use. This paper explains the types of aerosol devices available on the market and provides strategies for choosing the right device for optimal treatment of mechanically-ventilated patients.

From Admission To Graduation: The Impact Of Gender On Student Academic Success In Respiratory Therapy Education, Arzu Ari, Orcin Telli Atalay, Essam Ali Aljamhan

Respiratory Therapy Faculty Publications

Despite research in other allied health professions and medicine, the influence of gender on student performance in respiratory therapy (RT) academic programs and on the National Board for Respiratory Care (NBRC) examinations is unknown. Therefore, the purpose of this study was to identify the impact of gender on student academic performance from admission to graduation and to determine whether gender differences affected student success on the NBRC examinations. This study consisted of a retrospective analysis of 91 female and 22 male graduates at a southeastern U.S. university between 2003 and 2007. The variables of academic success included the students' entering …
