10 OBHG Education Subcommittee MENU QUIT

11 OBHG Education Subcommittee  Resistance = Prolongation I:E Ratio Purse-lip breathing  Prolonged expiratory phase Inspiratory Expiratory Ratio 2:3 MENU QUIT

12 OBHG Education Subcommittee Bronchoconstriction/Wet Heavy Lungs = Increased workload of breathing decreased gas exchange leads to  LOA NEED POSITIVE PRESSURE VENTILATION LOA and workload of breathing MENU QUIT

13 OBHG Education Subcommittee Blue = Bad (CYANOSIS) Diaphoresis = Sympathetic Stimulation Skin condition in distress MENU QUIT

14 OBHG Education Subcommittee Palpation  Predominantly used to find traumatic injuries  Tenderness, pain, crepitus  Subcutaneous emphysema Physical Exam MENU QUIT

15 OBHG Education Subcommittee Breath Sounds  Produced by air passing through respiratory system   Sound on inspiration (louder)   Expiration (Quieter) Auscultation MENU QUIT

16 OBHG Education Subcommittee Breath Sound Location I/E Ratio Description Bronchial Heard over trachea I E Loud, Harsh 2 to 3 High pitched ---------------------------------------------------------------------------------------------------------------- Broncho- Anteriorly: near I E Soft, Breezy Vesicular 1st and 2nd IC spaces Posteriorly: 1 to 1 Pitch is lower than Bronchial Between scapulas ---------------------------------------------------------------------------------------------------------------- Vesicular Lungs periphery I E Softer, swishy Not over sternum Pitch is lower over scapulas 3 to 1 than Broncho vesicular Normal Breath Sounds MENU QUIT
