An inspiration valve (VI) is arranged between the inspiratory flow rate source (11) and the inspiratory branch (3).

Application of positive pressure to the inspiratory phase of spontaneous respiration.

Viscosity and surface tension Inspiratory flow rate

Insulin is administered when the patient inspiratory flow exceeds a preset threshold.

Reproducible dosing is obtained by providing for automatic release at the same inspiratory flow rate and inspiratory volume each time drug is released.

A patient circuit (1) comprises an inspiratory branch (3) connected to an inspiratory flow rate source (11), and an expiratory branch (4) connected to the atmosphere through an expiratory valve (VE).

Inspiratory flow limitation (IFL) is involved in the pathophysiology of sleep-related breathing disorders.

The drug is released when the patient's measured inspiratory flow rate is in the range of from about 0.10 liters/second to about 2.0 liters/second, and the patient's inspiratory volume is in the range of from about 0.15 liters to about 0.8 liters.

The active agent formulation is delivered to a patient at an inspiratory flow rate of less than 17 liters per minute.

The dispersed particles are decelerated and inhaled in an inspiratory-flow rate independent manner, and with minimal wall losses.

Produce a quality inspiratory flow that will make it possible to homogenize the distribution of air in his lungs.

The active agent formulation is delivered to a patient at a low inspiratory flow rate for an initial period of time to increase bioavailability of the active agent.

During inspiration, the inspiration valve (VI) is open and the pressure of the inspiratory flow source is applied to the expiration valve (VI) to close the latter.

Our Breath Profiling Device (BPD) was designed to digitally asses an asthma patient’s inspiratory flow profile.

In this case it is important that the patient is able to generate a sufficient inspiratory flow in order to inhale the respirable particles out of the device.
