Q

Central Sleep Apnea

- Inspiratory/Expiratory Control

A

Dorsal Medulla = Inspiratory Control Center

Ventral Medulla = Expiratory Control Center

24
Q

Central Sleep Apnea

- Apneustic vs Pneumotoxic Center

A

Apneustic Center = Found in Lower Pons
- When stim: Increase inspiratory duration, decrease expiratory periods.

Pneumotoxic Center = Found in Upper Pons

  • When stim: Turn off inspiration, decrease phrenic nerve activity.
  • If lesions: Normal breathing rhythm resumes.
25
Risk Factors of Sleep Apnea
- Acromegaly: Increase tissue growth around respiratory muscles - Cushing Syndrome: Central Obesity + Buffalo Hump - DM II: Obesity - Hypothyroidism: Myxedema
26
Complications of Sleep Apnea
- Secondary Pulmonary Hypertension: Closing of blood flow to areas of lungs - Cor Pulmonale: Right Heart Failure due to pulmonary hypertension - Polycythemia: Increase RBC count due to hypoxic environment.
27
Stage of sleep when Apneic event occurs
REM.
28
Refeeding Syndrome
- Risk Factor: Not having had eaten for 5+ days - Occurs during hyperalimentation (refeeding) of malnourished (too quickly) resulting in major shifts in fluid and electrolytes = produces ANABOLIC response (building up) - Hallmark: Hypophosphatemia! As well as hypokalemia, hypomagnesemia, and thyamine deficiency. - Correct Tx: refeeding at 50% of energy requirements + thiamine. Note: Malnourishment is catabolic (breaking down)
29
Estimate of BMR
25 kcal/kg/day
30
Fats
9 kcal/gram - Fatty acids are heart's main source of fuel via phosphates - Fat needs = 30-40% of total calories
31
Protein
4 kcal/gram - Arginine and Glutamine: Helps repair, heal, build muscle. - Protein needs = 0.8 g/kg per day
32
Sugar/Carbohydrates
3. 4 kcal/gram - Brain's sole source of fuel. | - Leftover Calories after fat and protein.
33
Non-Protein Calories/Grams of Nitrogen
150: 1 Ratio - Note: Renal Failure = you want > 150:1 ratio because increase protein can harm the kidney - Note: COPD = you want
34
Hydration/Fluid Requirement
- 100 cc/kg for the first 10 kg - 50 cc/kg for the next 10 kg - 20 cc/kg for the remaining kgs. Fluid boluses: Calculated at 20 cc/kg of body weight.
35
Minimum fluids needed based on urine output
0.5 - 1 cc/kg/hr
36
Metabolic equivalent
1 kcal/(kg * h)
37
Respiratory Quotient for Carbohydrates, Proteins, Ketones (eucaloric), Ketones (hypocaloric), and triolein (fat)
Respiratory Quotient: CO2 eliminated/O2 consumed - Carbohydrates = 1 - Protein = 0.9 - 0.9 - Ketone (eucaloric) = 0.73 - Ketone (hypocaloric) = 0.66 - Triolein (fat) = 0.7
38
Kjeldhal Method
- Method for estimating protein content in food. - If patient needs to keep his nitrogen to build protein, you'll see less nitrogen in the urine. Therefore decrease in nitrogen = need for protein.
39
Method of measuring success.
- Pre-albumin - Transferrin - Retinol-binding protein
40
Confirmation tests for Brain Death
- Angiography - Electroencephalography - Transcranial ultrasound - Technitium-99m brain scan
41
Selye's Stress Triad
- Enlarged Adrenal Glands, Shrinking of lymphatic organ, and GI Ulcer
42
Stress of Changes
- Limbic system is stimulated - Ant pituitary: Increase ACTH and Cortisol - Sympathetic Center: Increase Catecholamines + Aldosterone - Post. pituitary: Increase ADH
43
AV anastomosis: Which layer?
Reticular layer, get rid of heat. Dermal ridge + papillae (or papillary dermis) = fingerprints
44
Which skin layer is aging most evident?
Subcutaneous tissue
45
What kind of changes occur in the epidermis and stratum corneum?
Epidermis things a little but not changes to the stratum corneum. Aging mainly affects extracellular matrix.
46
What affects everything in terms of aging/dying physiologically?
Hypoperfusion - Anaerobic metabolism - Vasoconstriction = peripheral pooling of blood - Efflux of Potassium - Influx of sodium and water
47
Respiratory Muscles that atrophy + Respiratory Sign of dying
- Type IIa muscle fibers | - Death rattle: Terminal respiratory secretions.
48
FAST
- Functional Assessment Scale - Focuses on an individual level of f(x) and ADL versus cognitive decline - 7A or greater = necessary to qualify someone for hospice. - Speech ability
49
PPS
Pallative Performance Scale | - Relates well to cancer patients.
50
Dangers of QT Prolongation
Progression to Torsades de Pointes
51
Drugs that Increase QT Interval
SSRI, Antiobiotics (specifically fluoroquinolone)
52
Wolf-Parkinson-White Syndrome
Delta wave due to Bundle of Kent which bypasses AV node.
53
Drugs contraindicated in WPWS
Beta blockers, calcium channel blockers | - Treatment: catheter ablation is symptomatic
54
Pericarditis
Diffuse ST elevation + gets better when sitting up/leaning forward
55
Drug to slow down heart rate
adenosine
56
Only murmur that doesn't get louder with increase venous return (squatting + respiration)
- Hypertrophic cardiomypoathy. Get's louder with valsalva (Phase 2) + abrupt standing.
