Comparison of a Nebulizer Using a Novel Aerosol Generator with a Standard Ultrasonic Nebulizer Designed for Use during Mechanical Ventilation
Figure 1: Diagram of SUN 145 (from product instruction manual) Ultrasonic nebulizers (USNs) generate aerosols without changing ventilator volumes or alarms. However, USN output varies with gas flow, is position dependent and generates heat. We wanted to determine whether the AeronebTM Professional Nebulizer System (Aeroneb Pro; Aerogen, Inc., Sunnyvale, CA)* has similar limitations. METHODS: We...
متن کاملComparison of jet and ultrasonic nebulizer pulmonary aerosol deposition during mechanical ventilation.
Increased delivery of aerosol to a model lung (attached to a mechanical ventilator) has been demonstrated with an ultrasonic nebulizer as compared to a jet nebulizer. This study examined whether the increased aerosol deposition with an ultrasonic nebulizer could also be demonstrated in vivo. Seven patients (6 male and 1 female) were studied during mechanical ventilalion (Siemens Servo 900C, Mid...
متن کاملDevelopment an Ultrasonic of a New Aerosol Nebulizer Generating Cell with
A new efficient cell was developed to generate a large quantity of aerosol using an ultrasonic nebulizer. The currently used conventional pail-type cell cannot generate such a large quantity of aerosol because a large portion of the mist is lost by agglomeration and subsequent liquefaction onto the cell wall and liquid surface. The newly developed cell is a chimney-type cell characterized by th...
متن کاملDelivery of salbutamol to nonventilated preterm infants by metered-dose inhaler, jet nebulizer, and ultrasonic nebulizer.
To identify the most efficient device for the delivery of bronchodilator aerosol to nonventilated preterm infants with chronic lung disease, we compared the metered dose inhaler (MDI) used in conjunction with a non-valved spacer, an ultrasonic nebulizer with a small medication cup, and two jet nebulizers. The subjects were enrolled in two double-blind randomized crossover studies. In study A (n...
متن کامل[Distribution of inhaled aerosol using nasal nebulizer].
In this paper, we examined distribution and deposition of inhaled 99mTc aerosols in human respiratory tract, nebulization equipment and expired aerosols. Jet nebulizers were used and aerosols were inhaled through the nose. Results were as follows: 1. On normal breathing, deposition rate of human respiratory tracts in normal subjects were 22% of total dosage and there was no difference from sinu...
