Activity & Immobility: Week 6 Flashcards
Gait
The manner or style of walking, including rhythm, cadence, length of stride, and speed
Spinal Malformations
Kyphosis: overexaggerated thoracic spine
Lordosis: overexaggerated lumbar spine
Scoliosis: exaggerated lateral curvature of the spine
Atrophy vs. Hypertrophy
atrophy- related to decreased use, causes decreased muscle size
hypertrophy- increased or enlargement of muscle. strengthening
Ergonomics
Science that focuses on factors or qualities in an object’s design/use that contribute to comfort, safety, efficiency, and ease of use
Body Mechanics
Center of gravity: lower the better
Lifting: use assistive devices when appropriate
Pushing or pulling: wide base of support
Fowler’s Bed Position
Head of bed at 45-60 degrees
Promotes lung expanision, useful for proceudres (NG insertion, suctioning), helps promote drainage post abdominal surgery
High Fowler’s Bed Position
Head of bed between 60-90 degrees
Promotes lung expansion the most, good position to put people in acute respiratory distress, good for patients experiencing regurgitation, (lowers the diaphragm to allow for FULL lung expansion) best for patients eating in bed
Semi-Fowler’s Bed Position
Head of bed between 15-45 degrees (usually 30 degrees)
Prevents regurgitation from eating/enteral feedings, helps promote lung expansion (minimally compared to flat) , most common position for patients in bed, we try never to lay patient flat because of aspiration risks for pneumonia risk, most hospitals want patients at least 30 degrees, however, for patients who have just had their groin accessed or have had some procedure or line in the groin, may be restricted to 30 degrees or lower
Trendelenburg
Entire bed tilted with head of bed lower than foot of bed
Used to facilitate postural drainage and promote venous return, can be used if patient hypotensive and to shunt blood to heart/brain and out of the extremities, used more commonly in emergency situations
Reverse Trendelenburg
Entire bed tilted with foot of the bed low to ground and head of bead high
Promotes gastric emptying, and prevents reflux, we use sometimes when patients have lines in their groins and cannot bend their legs so they are sitting up.
Modified Trendelenburg
Patient remains flat but legs elevated above the heart
Helps with hypovolemia a bit as well, helps with venous return (fluid getting stuck in legs)
Trapeze Bar, Mechanical Lift, Log Roll
Trapeze bar– allows patient to pull with upper extremities to raise trunk off the bed
Mechanical Lift- for immobilized/weak patients, make sure you know hospital policy
Log roll- for patients in spinal and cervical precautions [know procedures]
Venous Thrombus Embolism [VTE] and/or deep vein thrombosis [DVT]
VTE- clot that has detached from the wall [blocking blood flow in some way]
DVT- clot within the vein obstructing blood flow
Virchow’s Triad
Damage to the vessel wall
Alteration in blood flow (immobility/ bed rest)
Alterations in blood constituents (changed clotting factors, increased platelet activity)
Pulmonary Embolism
Deadly complication related to VTE/DVT that has lodged in pulmonary circulation blocking gas exchanged
