| Prone Positioning in ARDS is used when | pt does not respond to ↑ Pao2, also releives pressure off of the posterior aveoli |
| o2 toxicity can occur when | FIo2 >60% for more than 48hrs |
| Permissive hypercapnia | ventilate with smaller tidal volumes to allow paCo2 to rise slowly avoids barotrauma |
| Vent Bundle | 1. HOB 30-45 2. Sedation Vacation dayshift 3. Peptic ulcer prophylaxis 4. Venous Thrombus prophylaxis |
| High levels of peep can.... | can cause volutrauma and barotrauma, decrease BP, decrease CO, and preload. |

| Pelvic Trauma | Urinary/Bowel complications, swelling, eccymosis, deformity, pain control |
| Abdominal Trauma | Solid organs bleed out- hollow spill out gi fluids causing peritonitis, complications hypovolemia and sepsis |
| Abdominal Trauma tx | Peritoneal lavage >10ml = positive |
| Abd trauma nursing interventions | Airway, IV, NG, Foley, leave impaled object, no pain meds until DO, prepare for surgery |
| Flail Chest | 2 or more fractured ribs in a segment, paradoxic movement, crepitus, affected side sucks in on inspiration, rapid shallow RR |
| Flail Chest Tx | Airway, vent or supp o2, IV fluids, Surgery plates/screws, cpab/bipap |
| Rib Fx | Most common ribs 5-9, atelectasis, splinting, shallow RR, complication pneumonia |
| Rib Fx treatment | If pleura is damaged chest tube may be needed, no binding, deep breath, IS, opioids, and nerve block |
| Chest Tube insertion | arm above head, hob 30, aseptic, connect to drainage system, CXR |
| Chest tubes are for... | bringing back negative pressure so lung re-expands, removes air and or fluids from pleural cavity. |
| WET Chest tube chambers | 1. Suction chamber filled w/20cm water- bubbles ok 2. Water seal chamber 2cm water- bubbles mean air leak- tidaling is normal 3. Collection chamber- never emptied. |
| Diff between wet and dry chest tube systems | Dry suction chamber has a dial and no water is added to suction. |
| Chest tube Management | Maintain patency, loosely coiled, below the body, report fluid >100, SQ emphysema, do not clamp (pneumo risk), do not strip, tape air leaks, keep sterile water nearby. |
| Chest tube complications | SQ emphysema can effect airway if too much air is leaking, INFECTION, re-expansion of pulm edema, and if more than 1-1.5l is pulled hypotension |
| Cover sucking chest wounds with... | 3 sided occlusive dressing |
| Removal of chest tube | DC suction 24hrs prior, Inform, Medicate, Semi-fowlers or lying on unaffected side, aseptic technique by a physician, have pt bear down exhale upon removal, cover with xeroform, 4x4, and tape. Cxr and Assess lungs. |

| Out of all the bio-agents two are viral in this exam.. | small pox and ebola |
| DIC is | Bleeding and clotting at the same time- not a disease- a complication. Coag overdrives, IV thrombin increases, then fibrin, and enhances plt aggregation so much that it fails to clot anymore-hemmoraging. |
| DIC labs | ↑D-Dimer >1.37 ↑PTT & PT ↑FSP ↓ Plt ↓ Fibrinogen |
| Fibrin VS Fibrinogen | At the same time: Fibrin increases (clotting) and Fibrinogen decreases clotting = massive bleeding and capillary permiability |
| DIC tx | Fresh Frozen Plasma, PLT, Cryoprecipitate, Heparin Goal is to prevent massive coagulation by giving the heparin- a balancing act |
| Decreased Fibrinolysis | microthrombi obstruct vessels |
| DIC patients will look like... | pettichae, bruising, hemotypsis. hyoptensive, abd distension, ↓UOP, ↓decreased LOC |
| Solu-cortef/hydrocortisone | reverses increased capillary permiability |

| MODS is.. | results from SIRS, Metabolic Acidosis, failure of 2 or more organs |
| Omnious sign in MODS | ↑CO and ↓SVR >24 hours |
| MODS patients will have this.... | decreased UOP, NA retention from ↑ aldosterone , abdominal displacment perotonitis, early sign ↓ LOC, warm, mottleling, 3rd spacing, ↑HR, aveolar edema decreased surfactant to ards, |
| MODS Tx | Try to prevent sirs to mods. Hypermetabolic state increases glucose, tx hypotension, O2 PPV VENT, enteral nutrition, appropriate support of failing organs |
| ABG compensation rule | Full comp the ph will be normal Partial comp the ph will be abnormal if both metabolic and respiratory are out of range and the ph is normalizing, some kind of compensation is going on. |
| Normal Labs | BUN 7-20, PT 11-14, Lactate 0.1-1, Plt 100-450, Creat 0.6-1.35, CVP 8-12-15, PAWP 8-12, HGB 12-15, HCT 35-50, Albumin 3-5 |

| Botox | No vaccine, not contagious |
| If there is no tidaling ... | check if the pt is connected to suction, check for blockage, lung may have re-expanded. |
| Anthrax can cause | N/V Ascites, Shock widened mediastinum, black ulcer |
| Plague | Flea bites and contaminated meats, bloody sputum high fever chills, lymph node swelling. |
