Abstract:
Manual transcription inaccuracies have been reported to be a frequent occurrence in clinical practice, which has been confirmed in my institution. I explored alternative methods of obtaining data directly from the Puritan Bennett ventilator. The aim of this project was to record all of the ventilator settings and monitored data with wireless technology. I evaluated 2 data-capture methods: on-demand data capture into a personal digital assistant, and continuous ventilator networking with a stand-alone computer. I was successful in both the intensive care unit and laboratory environment in transferring ventilator data, for up to several days, and with a data-capture interval as short as 60 seconds.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...
