Bifurcation of trachea Arch of aorta T4-t5 |
|
|
Carina |
Last tracheal ring, separates right and left At level t4 Sensitive mucous- cough reflex |
|
|
L and R main bronchus |
R- shorter more vertical and had 3 divisions L- (inf to arch of aorta) longer wider and 2 divisions |
|
|
Haldane effect |
As conc of O2 decreases, co2 carrying capacity of heam increases |
|
|
Wheeze/stridor |
Wheeze- Worse on expiration Stridor - |
|
|
Oblique fissure levels |
T2 at the back, rib 6 front |
|
|
Haldane effect |
Hb gives up 02 affinity for c02 increase and vice versa |
|
|
02 delivery |
Stroke volume x heart rate x oxygen sat of hb |
|
|
Pressure changes insp |
Pip negative ( due to expanding thorax'counter recoil') Insp muscles contract- pip becomes more neg TransP pressure becomes more positive *same as alveoli distension* Increase alv volume so difference btwn atmos and alv cause air to flow in |
|
|
Pressure changes expiration |
Insp muscles relax, chest recoil Pip becomes less neg, so Ptp less positive Increase in alv pressure due to decrease in volume ( distention) Breath out |
|
|
Airway resistance eq and pous3illes law |
Diff in P = V×R V= airflow R= resistance *R directly proportion to viscosity and length R is inversely prop to to radius ^4 |
|
|
Pleural effusion |
Drain costodiag recess ABOVE 9th IC space |
