O2 Therapy Flashcards
How important is O2 to life?
Oxygen is Essential to life
How long can a person last without O2 before irreversible brain damage occurs?
4-6 mins before Irreversible brain damage
Without O2, what happens to celluar metabolism?
Cellular metabolism will cease and death will eventually occur
What is the function of the Respiratory system?
It is the exchange of O2 and Co2 between the external environment and the circulatory system.
What are the major features of the lung?
Bronchi, Bronchioles, Alveolis
What are the Alevioles?
They are tiny microscopic vessel-lined sacs in which O2 and CO2 gas are exchanged
What is the pleural cavity composed of?
It comprises layers of membrane lining in the lung and chest cavity.
Roles of Radiographers, how do we ensure the tube does not become a source of Infections?
- We ensure the tube does not become a source of infections by letting only a single patient use it and be discarded after use.
What must we be ready to respond to?
The Radiographer (we) must be ready to respond to potentially dangerous changes in the patient
Whats the Radiographers responsibility with reposition the O2 equipment? Ie. Tubes
So that they do not cause artifacts in films or become superimposed over anatomy for radiographic procedures. TUBES NOT KINKED OR DISCONNECTED
UNER NO CIRCUMSTANCE
should the O2 equipment be completely removed to obtain a radiograph.
What is the Pulmonary Function?
It is the lung’s ability to exchange O2 and Co2 efficiently.
What blood transports oxygen to the body tissue?
The Arterial Blood
What is ABG’s abbreviated?
Arterial Blood Gases
What is Arterial Blood gases?
It is a lab value that measures the arterial blood concentration of O2, CO2 and PH (ACIDITY) and other gases
pH of Normal Arterial blood
7.35-7.45
What condition develops when the ABGS becomes inadequate to meet patient needs?
Hypoxemia ( Not enough 02 in blood)
When a person has HYPOXEMIA, this means?
It is a condition of insufficiency of oxygenation in the blood ( Not enough O2 in blood)
When a person is HYPOXIC, this means?
This is a deficiency in the amount of O2 reaching the tissues
WHAT ARE THE SIGNS OF HYPOXIA?
Rapid heart rate, Cyanosis, Dyspnea, Rapid and shallow breaths.
What 4 tissues are most sensitive to Hypoxia?
Lung, Liver, Heart, Brain
What are the average Rate of Respiration for ADULTS?
12-20 breaths per min
What are the average Rate of Respiration for a child ?
20-30 breaths per min
What are the average Rate of Respiration for babies/infant?
30-60 breaths per minute
