Ventilatory Pump
|
Neuromuscular structures between respiratory center in brain stem and muscles to move the thoracic cage to generate negative pressures
(medulla, spinal cord, peripheral motor nerves, NMJ, muscles (diaphragm)) |
|
|
Ventilatory Load
|
Restrictive Load (Obstructive): resistance offered by the tubes of the system to move air into the lungs; related to caliber
Elastic Load: (Restrictive): opposition to inflation; stiffness Minute Ventilation (metabolic) load: Demand of the body on the respiratory system (via respiratory center) to meet its functions (oxygenation and acid-base homeostasis) |
|
|
Neuromuscular deficits + dyspnea + clear lung exam and cxr
|
Ventilatory Pump deficiency
|
|
|
Stridor correlates with what structures
|
Pharnx/larynx
Often w sore throat and pain upon swallowing |
|
|
Cough + wheezes + clear radiograph
|
Differentiate toward lower airways
|
|
|
Medications precipitating methemoglobinemia
|
Nitrates, phenazopyridine, benzocaine
|
|
|
Deep (kussmaul) breathing is suggestive of what
|

respiratory acidosis = hyperventilation |
|
|
Respiratory acidosis
|
Build up of carbon dioxide in the blood due to hypoventilation
|
|
|
Metabolic acidosis
|
Increased production of metabolic acids
|
|
|
Risk factors for pulmonary embolism other than DVT
|
Long bone fracture (fat), difficult delivery (amniotic fluid), malignancy (tumor), vascular procedures (air)
|
|
|
Stridor
|
Monophasic wheeze loudest over central airways; is prominent within upper airway obstruction and implies a life threatening emergency
