What is the user interface? |
|
Definition
| The knobs or controls on a control panel that is set by the person operating ventilator |
|
|
Term
What is the control system? |
|
Definition
| Interprets the operators settings and produces and regulates the desired output |
|
|
Term
When is battery pwr used? |
|
Definition
| Usually is used for a short time, such as for transporting a ventilated pt. It also can be used in the home as a backup pwr source if the home’s electricity fails |
|
|
Term
What does pneumatically pwrd mean? |
|
Definition
| Ventilators that depend entirely on a compressed gas source for power |
|
|
Term
What are the two types of pneumatically powered ventilators? |
|
Definition
| Pneumatic ventilators and fluidic ventilators |
|
|
Term
What is an example of each for the 2 types pneumatically pwrd vents?(Name and brand of ventilator) |
|
Definition
| The Bird Mark 7 is an example of a pneumatically pwerd and operated ventilator. An example of a ventilator that uses fluidic control circuits is the Bio-Med MVP-10 |
|
|
Term
What is a microprocessor-controlled ventilator? |
|
Definition
| A single chip made of integrated circuits (controls the functions of capacitors, solenoids, and electrical switches which regulate the phasing of inspiration and expiration and the monitoring of gas flow) |
|
|
Term
In a combined pwr ventilator: which pwr source provides the energy to deliver the breath? |
|
Definition
| The pneumatic power (i.e.the 50 psi gas sources) |
|
|
Term
What is an open loop system? |
|
Definition
| Ventilators that are not microprocessor controlled (unintelligent systems) |
|
|
Term
Why is it termed an open loop system called an unintelligent system? |
|
Definition
| B/c the ventilator cannot be programmed to respond to changing conditions |
|
|
Term
What is a closed loop system? |
|
Definition
| Often described as “intelligent” systems b/c they compare the set control variable to the measured control variable |
|
|
Term
What is an example of a closed loop system? |
|
Definition
| The mode of ventilation called mandatory minute ventilation |
|
|
Term
Where is the control panel located? |
|
Definition
| On the surface of the ventilator and is monitored and set by the ventilator operator |
|
|
Term
What makes up the control panel and what do these controls regulate? |
|
Definition
| Has various knobs or touch pads for setting such components as tidal volume, rate, inspiratory time, alarms, and FiO2. These controls ultimately regulate four ventilatory variables: flow, volume, pressure, and time |
|
|
Term
What is a pneumatic circuit? |
|
Definition
| Aka pathway; a series of tubes that allow gas to flow inside the ventilator and between the ventilator and the pt |
|
|
Term
What are flow control valves? |
|
Definition
| Control or direct gas flow by opening and closing either completely or in small increments. These valves which are driven by various motor based mechanisms, have a rapid response time and gr8 flexibility in flow control |
