Evaluation of Lung Deposition of Aerosol Via HFNC in Healthy Adults

NCT02519465 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 25

No results posted yet for this study

Summary

The aerosol associated with noninvasive ventilation (NIV) and high flow therapy with nasal interface have been employed in an attempt to relieve respiratory distress and optimize the deposition of drugs by inhalation.

Some studies report the effects of NIV association with fogging in healthy subjects, asthmatics and COPD 7.8, but studies evaluating the association between high flow nasal mist interface and therapy are scarce and most are found in vitro and animal models. The objective of this study is to evaluate the deposition of the aerosol scintigraphy using the high flow nasal interface system with vibrating mesh nebulizers using in healthy adults.

For inhalation was used diethilene penta-acetic triamine technetium (99mTc-DTPA) with radioactivity of 1 millicuries (Noble et al., 2007) and 0.9% saline solution with a total volume of 1 ml using vibrating mesh inhaler (Aerogen Ltd, Galway , Ireland) with the respiratory care system for the high flow ( Fisher \& Paykel healthcare, New Zealand) and nasal cannula (Fisher \& Paykel healthcare, New Zealand) with flow 10l/min

OTHER

30l/min
