Week 1 Study Flashcards
What is the importance of Oxygen?
To oxygenate the blood and lungs and perfuse the tissues
What are the 3 things you plan for a patient with oxygenation and circulation issue goals?
- Maintain patient airway
- Improve comfort/ ease of breathing
- Maintain / Improve oxygenation / Tissue Perfusion
What comfort measures can a nurse do to improve patient w/ breathing?
Put bed into semifowlers or high semifowlers and encourage deep breathing / coughing
Does mobility decrease your risk of developing pneumonia?
Yes, it promotes circulation and keeps things aaaaa flowwwwwing.
When teaching deep breathing and coughing, how many deep breaths before the 2 or 3 coughs?
3 deep breathes, on the third breathe don’t exhale, cough instead.
What do humidifiers do?
Increase the moisture in air. When pt. on 02 therapy, membranes can dry up.
What medication can be given to increase 02 flow to lungs?
Bronchodilators
When would you insert an artificial airway?
When patients airway is obstructed or likely to become obstructed.
How do you measure what artificial airway to put in place?
From the corner of lips to the jaw bone (not proper wording, still need to look up)
When would you insert an oropharnygeal artificial airway?
When the patient is unconscious. If they are conscious, this could cause them to gag.
When would you insert a naropharyngeal artificial airway?
When the patient is conscious.
How often should mouth care be provided when artificial airway is in place?
Every 2 hours.
What are the early signs of hypoxia?
Confusion, Restlessness, Anxiety
What is the late sign of hypoxia?
Cyanosis (bluish discolouration around mucous membranes)
What are the 2 categories of 02 Delivery?
- High Flow
2. Low Flow
High Flow 02 methods include….
1.
2.
- Venturi Mask
2. Large Volume Nebulizer
Low Flow 02 methods include….
1.
2.
3.
- Nasal Canula
- Non rebreather mask
- Partial rebreather mask
How do you give 02 therapy to a pediatrics patient?
02 hood
What is the maximum 02 in nasal canula?
6 ml… although most often not above 3 mL.
02 should be applied at what minimum range of 02 stats?
88 - 92 SP02 on Room Air
What is the purpose of Insentive Spirometery?
Helps a patient to deep breathe and provides the patient with visual feedback about their depth of breathes.
Assessing a patients baseline on the spirometer before surgery, what would you expect their ability to be post surgery?
1/2 to 3/4 of baseline.
Spirometers work best alongside what other tool to decrease the chance of developing postoperative pneumonia?
With deep breathing and coughing exercises.
What is the difference between a non rebreather and partial rebreather mask?
Non Rebreather: one way valve
Partial Rebreather: not one way valve
