9B: Covid Flashcards
What are acute symptoms of covid?
Fever, chills, cough, SOB, fatigue, myalgia, headache, loss of taste or smell, sore throat, congestion, nausea, diarrhea
What three cardiovascular impairments are the result of covid?
- V/Q mismatch
- Cardiac myocarditis
- Thromboembolus
Describe V/Q mismatch with covid
- ARDS like presentation
- Lower surfactant levels
- Hypoxemia
Why can you develop hypoxemia due to covid?
Fluid is blocking V/Q matching
What is cardiac myocarditis?
Inflammation of muscle fibers
What are the effects of cardiac myocarditis?
- Arrhythmias
- Increased myocardial O2 demand
What are interventions for acute covid?
- Proning
- Maintain O2 transport system
- Maintain functional endurance
- IMT as needed
How do you work to maintain the O2 transport system?
- Optimal supplemental O2
- Maximize O2 stats with movement, hygiene, coughing
What is proning?
Prone positioning that is recommended in acute care, especially for severe cases and pulmonary decompensation
What is the recommended time for proning?
12-16 hours straight
Why does PT need to assist with proning?
Prevent pressure injuries at head, clavicles, sternum, ASIS, patellas, feet
What are the three effects of proning?
- Gravity allows airways to open back up
- Post lung segments function
- Re-establish V/Q matching to increase PaO2 levels
What is the intensity of acute PT for covid?
12 on the Borg or 2 on the Modified Borg
What is the frequency of acute PT for covid?
5-7 days/week
Describe early rehab in the home or outpatient following covid?
- IMT and HEP
- Teach controlled or deep or pursed lip breathing for ambulation
- Breath timing with conditioning
How is covid effecting patients long-term in comparison to other ICU stays?
Greater muscle mass loss
Why might there be greater muscle mass loss with covid?
- Viral load
- Impact of prolonged lack of oxygenation on muscle tissue
- Long periods of increased RR, HR, decreased PaO2
What are home health interventions for covid?
- Monitor O2 and supplement
- Maintain functional mobility
- Endurance and strength
- Balance
- ICUAW
- QOL
What is the duration of strength training following covid?
Start with 15-20 reps of each exercise, can break into multiple sets
What is the intensity of strength training following covid?
Start with low weight and high reps and then progress
What is the frequency of strength training following covid?
Subacute: 2-3 days/week
Home health: 2-4 days/week
What is the definition of long covid?
Signs, symptoms, and conditions that continue to develop after an acute covid infection
What is the timeframe of developing long covid?
Disagreement - 2 weeks to 2 months after initial infection
What are symptoms of long covid?
SOB, fatigue, chest pain, weakness, brain fog, headache, dizziness, anxiety
