6 P's of DYSPNEA
Possible foreign body
Pulmonary embolus
Pneumothorax
Pneumonia
Pump failure
Pulmonary bronchial constriction
Dyspnea has six major causes: 1. (Possible) foreign bodies can become trapped or logged within the trachea restricting air flow. 2. Pulmonary embolisms can prevent complete oxygenation of the blood in the alveoli due to restricted blood flow. 3. Pneumothorax collapses the lung and prevents full expansion, restricting oxygenation. 4. Pneumonia leads to poor lung ventilation too. 5. Pump failure refers to the heart not beating appropriately. If the heart is not perfusing the lungs, then the lungs will be unable to oxygenate the blood. 6. Pulmonary bronchial constriction prevents the passage of air into the lungs which contributes to dyspnea. Don't forget to save this, nurses!
