Nursing 211-O2/trach
Oxygen/trach info
| Question | Answer |
|---|---|
| What is the normal breathing stimulus? | high CO2 |
| What is the COPD breathing stimulus? | low O2 |
| What two influences can prevent atelectasis? | coughing and deep breathing. |
| What is hypoxia? | decreased O2 in the tissue. |
| What is hypoxemia? | decreased O2 in the blood. |
| what is the goal of O2 therapy? | as low a dose as possible. |
| Nasal Cannula O2 never goes higher than how many L/min? Why? | 6. It can disrupt or injure nasal passages |
| when do you use humidification with NC? | greater than 4 L/min. |
| Patients who use a breathing mask are at risk for what? | aspiration/skin breakdown. |
| A simple face mask uses how many L/min? | 5-8 |
| A simple face mask provides how much FIO2? | 40-60% |
| A partial rebreather mask uses how many L/min? | 6-11 |
| A partial rebreather mask provides how much FIO2? | 60-75% |
| why does a partial rebreather mask bag need to be 2/3 full? | If not kept 2/3 full, they rebreath too much of their own CO2. |
| What FIO2 does a non-rebreather mask provide? | 80-95%. Highest concentration possible with mask. |
| What do non-rebreathers have that partials don't? | flaps and 1-way valve. |
| Venti-masks are frequently used for what patients? | ones with COPD w/ chronic CO2 retention. |
| What are symptoms of EARLY O2 toxicity? | GI upset, chest pain, dyspnea, PaO2 >100 |
| What are symptoms of LATE O2 toxicity? | decreased vital capacity/compliance, crackles, low PO2 |
| what if a patient is on 100% O2 for more than 2 days? | Ask physician for ABG. |
| What isa critical component in preventing atelectasis? | Nitrogen. |
| what is the downside to a trach? | Bypasses humidification, so trach must be supplemented with humidity. |
| What must you do with metak trachs before an MRI? | Change to plastic. |
| How do fenestrated trachs work? | take out inner cannula, put stopper over trach hole. Blocks trach and forces air through natural airway. |
| What must you remember to do when using a fenestrated trach regarding the cuff? | MUST deflate or it totally occludes the airway. |
| What are passey-muir valves used to promote? | louder voice, improved swallow, stronger cough, increase oxygenation |
| when using a passey-muir valve, what must you do regarding the cuff? | deflate for expiration. |
| when a passey-muir valve is first placed, what must you assess for? | an adequate airway |
| What does the trach cuff do? | balloon that seals area between cannula and tracheal wall. |
| How can you tell if there is a leak in the trach cuff? | if you hear air, whisper or cough |
| In trach use, what can cause wall breakdown? | long term inflated cuff, infection, misalignment, incorrect tube size, pt general health |
| when is trach extubation emergent? | w/in first 72 hrs because the hole can close. |
| What should you monitor for in post-op trach insertion? | VS, pulse ox, mucous membrane color, s/s of resp distress and shock |
| what should you encourage in post-op trach insertion? | coughing and deep breathing |
| What are post-op complications of trach insertion? | pneumothorax, subQ emphysema, bleeding, accidental trach extubation |
| Prior to cleaning a trach, what must you do? | suction. |
| if cleaning a metal trach, what should you use? | ONLY saline. |
| What should you do regarding VS before and after suctioning? | elevate HR, RR, O2 sat to the minimum |
| How long should you suction? | Intermittedly for 5-10 sec. |
| Is it normal to cough during suctioning? | Yes. |
| How many times may you suction per session? | max of 3 times. |
| What are trach suctioning complications? | tissue trauma, hypoxia, vagal stimulation, bronchospasm, infection |
| What should be included in home care teaching for trachs? | shower guard, humidify air/O2, MedicAlert |
