Oxygenation Flashcards
What is a Nasal Canula used for?
Provides a small amount of supplemental oxygen at low flow rates up to 5L per min
Commonly used for patients requiring low levels of oxygen.
What is the purpose of a Reservoir Nasal Canula?
-Helps to conserve oxygen while providing adequate flow.
- stores 20 mL of oxygen
- 1/2 to 1/4 flow rate of standard cannulas
-settings of 0.5 - 2L/min
What is the minimum flow rate for a simple mask to be effective?
6L per min
Necessary to flush out carbon dioxide that passes through the mask.
What percentage of oxygen does a Non-rebreather mask deliver?
60%-80% of oxygen at flow rates of 10-15L/min
Used in emergency situations for high oxygen needs.
What distinguishes a Partial rebreather mask from a Non-rebreather mask?
Contains a two-way valve that allows some of the breath back into the bag
This feature helps to maintain a higher oxygen concentration.
What is the function of a Venturi Mask?
Mixes oxygen with room air to create high-flow enriched oxygen of desired concentration
Provides an accurate and constant FiO2 despite varied respiratory rates and tidal volumes.
What is the purpose of humidification in oxygen therapy?
Helps alleviate a sore, dry, and bloody nose by adding humidity to the oxygen
Achieved through a water bottle connected to the concentrator or liquid system.
What is the Acapella device used for?
Improves clearance of secretions
What is the purpose of huff cough?
-A technique used to help clear airways
-Clears sputum
What is the benefit of purse-lip breathing?
Prevents bronchiolar collapse and air trapping
Useful for patients with obstructive airway diseases.
What does vibration do in respiratory therapy?
Mobilizes secretions
Can be part of therapies to clear airways.
What is diaphragmatic breathing?
Use of diaphragm instead of accessory muscles to achieve maximum inhalation and slow respiratory rate
Promotes better oxygen exchange.
How long should suctioning be performed?
10-15 seconds or until oxygen saturation goes down
Important to prevent hypoxia during the procedure.
What are common symptoms of Iron deficiency anemia?
Fatigue and activity intolerance due to inadequate oxygen
Affects overall energy levels and physical activity.
What position should the head of the bed be elevated to aid lung expansion?
Semi-fowlers
What is the recommended coughing frequency while awake?
Every 1-2 hours
Helps to keep airways clear.
What is Thoracentesis?
Taking a long needle to clear liquid in the lungs
A procedure used to relieve pleural effusion.
What is the normal inspiration/expiration ratio?
1-2
Indicates normal respiratory function.
What defines chronic respiratory issues?
Symptoms lasting over 6 months
Important for diagnosis and treatment planning.
What is atelectasis?
Lung collapse
Atelectasis can occur due to various reasons, including obstruction or pressure on the lung.
Define cyanosis.
Blue discoloration
Cyanosis indicates inadequate oxygenation in the blood.
What does clubbing of the fingers indicate?
Clubbing of the fingers is often a sign of chronic hypoxia
It can be associated with conditions like COPD and lung diseases.
What are hypoxia and hypoxemia?
Hypoxia is low oxygen in tissues; hypoxemia is low oxygen in the blood
Both conditions can lead to serious health issues.
What is exacerbation in the context of respiratory conditions?
Worsening of symptoms
Exacerbations can lead to increased difficulty in breathing and require medical intervention.
Define perfusion.
How much blood and oxygen is getting to the tissue
Adequate perfusion is crucial for organ function.
What is Cheyne-Stokes respiration?
Rapid breathing followed by slow breathing
This pattern can indicate severe medical conditions.
What is orthopnea?
Difficulty breathing while laying down
Patients often need to sit up to breathe comfortably.
What does apnea mean?
No breathing
Can occur in various medical conditions, including sleep apnea.
Define bradypnea.
Slow breathing
It can be a sign of respiratory distress or other medical issues.
What is the target oxygen saturation for COPD patients?
88-92%
Too much oxygen can be harmful to COPD patients.
What is hemoptysis?
Coughing up blood
Hemoptysis can indicate serious underlying conditions.
What does greenish/yellow sputum indicate?
Signs of infection
Sputum color and odor can provide clues about respiratory infections.
What is hyperventilation?
Breathing really fast, inhaling too much oxygen
This can lead to decreased carbon dioxide levels in the blood.
What are accessory muscles?
Muscles used to assist in breathing, such as the diaphragm
Accessory muscle use indicates increased work of breathing.
Why is it important to monitor vitals and level of consciousness (LOC)?
To assess respiratory and overall health status
Changes can indicate deterioration in a patient’s condition.
What is the purpose of raising the head of the bed in respiratory distress?
To facilitate easier breathing
Fowler’s position is often used for patients with respiratory issues.
What techniques are used to improve breathing in patients?
Pursed lip breathing and deep breathing exercises
These techniques help to reduce breathlessness.
What is the purpose of a spirometer?
-To measure lung function
- prevent pneumonia
It helps in assessing the severity of respiratory conditions.
What is thoracentesis?
Fluid in the lungs is taken out by a needle
This procedure can relieve pressure on the lungs.
What is a pulmonary function test?
A test to assess lung function
It helps in diagnosing and monitoring respiratory diseases.
