Abstract: A medicinal diffuser system for patients is provided and includes a nasal cannula, a flow stream vessel and a mount assembly. The medicinal diffuser system is mountable over a patient's head and permits a steady flow of air while administering a medicinal agent. The medicinal diffuser permits a steady flow of air to flow into the patient's nasal cavity while administering a medicinal agent.

Abstract: A nasal airway pressure monitoring system and method for use with neonatal patients is provided. The nasal airway pressure monitoring system has a nasal catheter, a pressure monitor, and a respiratory circuit supplying a respiratory gas. The nasal catheter is connected at a first end to the pressure monitor via a sample line and the second end of the nasal catheter is positioned in a nares. Upon delivery of gas flow through the patient respiratory circuit, the nasal catheter transmits pressure waveform data from the nasal airway to the pressure monitor. The pressure monitor processes the pressure waveform data. If the mean airway pressure is outside of a pre-set range of maximum and minimum limits, an alarm is triggered.
