Pulmonar Disease - Answer *classified into 2 broad categories
-restrictive vs obstructive
- infectious vs non-infectious
Restrictive disorders - Answer *unable to breath air in
* these ppl have low lung volumes on PFTs
*lung volumes are the amount of air the lungs contain at a given time during ventilation.
*Examples= aspirations, pulmonary fibrosis, atelectasis, bronchiectasis, bronchitis, and
pulmonar edema
Obstructive disorders - Answer *unable to exhale the air that has been inhaled
* have high volumes on PFTs
* Examples= asthma and COPD
Infectious Disorders - Answer * Pneumonia and TB
Non-infectious pulmonary disorder - Answer pulmonar fibosis, lung cancer, and
pulmonary hypertension
Acute Respiratory Failure - Answer * 2 main types= hypoxemia and hypercapnia
* may result from direct injury
* may be triggered by an injury or dysfunction to one or more body systems or organs
* may occur post-operatively secondary to anesthesia or narcotics
* in either case the main dysfunction is an impairment in diffusion which result in low
, oxygen levels or retained CO2
* most pulmonary diseases can cause respiratory failure as can brain or spinal cord
injuries
Hypoxemia respiratory failure- Answer * PaO2 less than or equal to 50mmHg
* from inadequate diffusion of oxygen from the alveoli to the capillaries
* disorder examples= pulmonary edema, pulmonary embolus, and pneumonia
Hypercapnic respiratory failure - Answer * PaCO2 greater than or equal to 50mmHg
* from inadequate alveolar ventilation
* cause= depression of respiratory function from meds, abnormal spinal cord, disorders
of the medulla, disease of neuromuscular junction, chest wall injury, COPD, and
obstruction or large airways.
Pneumothorax - Answer * presence of air or gas in the pleural space
* air may press against the lungs and cause the lung to collapse
* 2 main types = spontaneus and secondary
* clinical manifestations = sudden pleural pain, tachypnea, dyspnea, decreased breath
sounds, and HYPPEROSANCE TO PERCUSSION
Spontaneous pneumothorax - Anwer * P Populate in males 20-40 years of age that are
tall and thin
* may occur in bleb ruptures in ppl with emphysema
* smoking increases the risk
* bleb ruptures may be at rest or exercise and in the apexes
genetic component of family history
Secondary pneumothorax - Answer traumatic induced
tension pneumothorax air trapped unable to escape
