Due to COVID-19 we are restricting visitors inside PHS to minimize contact. We are requiring the use of our curbside option for any patient supplies picked up at our office. Additionally, at this time, we are unable to provide PPE to the community, including patient families. In order to continue to provide care, we must maintain access to these supplies for our front-line staff. Thank you for your understanding.
The heating spiral contains heater wire to warm the breathing gas inside the tube.
The insulating spiral uses a bubble of warmed air around the breathing gas to shield it from the outside environment.
Like a double-paned window, the inside and outside surfaces of the tube are physically separated, to reduce cooling and helps maximize the level of humidity remaining in the gas all the way to the patient.
