Fisher & Paykel RT380 Circuit

Description:

EVAQUA technology allows water vapor to diffuse out. Diffuses out through the expiratory limb wall before it has an opportunity to condense into liquid water within the circuit limb or the ventilator. The result is an easy-to-use system. It is designed so that the breathing circuit can remain closed and free of clinician intervention. This, in turn, benefits both the patient and the clinician.

Features

1. Promotes a closed system
2. Minimizes condensate-related ventilator alarms
3. Filters remain dry
4. The entire system keeps a low resistance to flow
5. Work of breathing is minimized
6. Circuit maintenance time is reduced

Breathing systems are utilized to provide oxygen and anaesthetics and to eliminate carbon dioxide in anaesthesia. They are comprised of various components including fresh gas flow bag, the reservoir bag, breathing tubes with expiratory valves, as well as the patient connection.Breathing system is an array of components that connects the patients’ airway to the machine via which the gas mixture that is controlled is dispensing. It provides gases to patients, eliminates expired gas , and controls the humidity and temperature of the mixture. It can be used to control spontaneous or assisted breathing. It also has ports for airway sampling, gas flow, pressure and monitoring of volume.

CHARACTERISTICS OF IDEAL BREATHING SYSTEM

1. It must be simple, secure and affordable.
2. Capable of delivering the desired inspired gas mixture.
3. Allow spontaneous, controlled or assisted ventilation for all ages.
4. Effective and allows for the flow of fresh gas to be low.
5. Safeguarding patients from barotrauma.
6. Compact, sturdy, and light in weight.
7. It is easy to remove gasses that are leaking out.
8. The process of warming and humidification of gases inspired by the heat.
9. Effectively reduce CO2.
10. Low resistance: Must be of minimal length, maximum internal diameter, and not have abrupt curves or abrupt change in diameter.
11. Dead-space should be as minimal as possible.

FAQ’S:

1. How does a breathing circuit work?

Ans- Breathing Circuits allows water vapour to diffuse out through the expiratory limb wall before it has an opportunity to condense into liquid water within the circuit limb or the ventilator. 

2. What is a patient breathing circuit?

Ans- A breathing system or breathing circuit is a medical device used to deliver oxygen, remove carbon dioxide, and deliver inhalational anaesthetic agents to a patient.

3. Is the breathing circuit dead space?

Ans- Dead space in the breathing circuit is the space where inhalation and exhalation coincide. Since patients breathe in and out of the same tube, they could inhale unfiltered (containing CO2) exhaled gas.

4. What is a Magill circuit?

Ans- It consists of a three-way T-tube connected to the fresh gas outlet (F), a breathing bag (B) and a reservoir tube (R). The other end of the reservoir tube is connected to the patient (P) and a spring-loaded expiratory valve (V).

5. Do breathing exercises actually work?

Ans- If practised regularly, breathing exercises can help rid the lungs of accumulated stale air, increase oxygen levels and get the diaphragm to return to its job of helping you breathe.

6. What happens to your body when you do breathwork?

Ans- Breathwork helps put the brakes on an acute stress response and diverts the health problems associated with chronic stress. By eliciting the body’s relaxation response, deep abdominal breathing helps reduce blood pressure.

7. What happens to the brain during breathwork?

Ans- When you do Breathwork regularly, it strengthens the neuro-pathways to your inner intelligence and subconscious and allows for easier access to it on a day to day basis. It is a powerful way to support you in freeing yourself from your egoic mind and integrating this deep inner work into your everyday life.

8. How long should you use a breathing machine?

Ans- As long as your healthcare doctor insists.

9. What are the different types of breathing circuits?

Ans-  Breathing circuits are usually classified as open, semiopen, semiclosed, or closed.

10. What are the 4 stages of ventilation?

Ans- There are four stages of mechanical ventilation. There is the trigger phase, the inspiratory phase, the cycling phase, and the expiratory phase.

11. What are the 5 steps of ventilation?

Ans- 1) Pulmonary Ventilation, External Respiration, Transport of gases through blood vessels, Internal Respiration, Cellular Respiration

12. What are the three types of breath for a ventilator?

Ans- Controlled, Assisted, Supported
