CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) ALREADY GRADED A+
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= spontaneous and secondary
* clinical manifestations= sudden pleural pain, tachypnea,
dyspnea, decreased breath sounds, and HYPPEROSANCE TO
PERCUSSION
