The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.

FAQs
Pressure and flow conditions help determine how much liquid reaches the target and how it is distributed. Along with nozzle geometry, they influence droplet size, spray pattern, and coverage. Engineers therefore evaluate flow rate and pressure together rather than treating either variable in isolation. Appropriate control can improve distribution uniformity while limiting overspray, material waste, and unwanted environmental release.
Nozzle geometry shapes the exiting liquid into a particular droplet distribution and spray pattern. This directly affects whether a surface, volume, or process zone receives consistent coverage. Selecting and evaluating the nozzle in relation to operating conditions allows engineers to control application behavior, improve material efficiency, and match the spray to tasks such as coating, cooling, cleaning, fire suppression, or agricultural treatment.
These components work as a coordinated delivery path. The reservoir holds the liquid or suspension, the pump drives movement, piping conveys it, and valves regulate flow through the system. Their interaction supports controlled delivery to the nozzles and enables adjustments to operating conditions. Engineering attention to this arrangement helps maintain process control and supports reliable, uniform application across the intended zone.
Evaluation commonly examines flow rate, pressure, and coverage, then considers whether the observed distribution matches the process requirement. Engineers also review maintenance needs because component condition can affect continued performance. Coverage results help identify inefficient delivery or uneven treatment, while the combined measurements provide a basis for improving material use, process control, and operational reliability.
Assessment begins by checking the reservoir, pump, piping, valves, and nozzles as an integrated arrangement. Engineers then examine operating pressure and flow rate, observe the resulting spray pattern and droplet behavior, and evaluate coverage across the target area or process zone. Reviewing maintenance requirements and potential overspray completes the assessment, helping confirm controlled delivery and safer operation.
Engineers may select this approach when a process requires controlled liquid or suspension delivery across a surface, volume, or defined zone. Supported uses include surface coating, cooling, cleaning, fire suppression, and agricultural treatment. The choice is especially relevant when distribution uniformity, material efficiency, and process control matter, or when reducing overspray, waste, and environmental release is important.
Maintenance requirements are part of performance evaluation because the reservoir, pump, piping, valves, and nozzles must continue to regulate pressure and flow effectively. Engineers also consider operator safety and the possibility of overspray or environmental release. Regular attention to these factors supports more reliable coverage, reduces waste, and helps keep the process within its intended operating conditions.
