| 1. | Lower impedance indicates greater intrathoracic fluid volume and blood flow.
|
| 2. | I assume it is related the raised intrathoracic pressure caused by coughing.
|
| 3. | In this situation the abnormality is usually referred to as an intrathoracic stomach.
|
| 4. | During expiration, the positive intrathoracic pressure causes decreased blood return to the right side of the heart.
|
| 5. | During respiratory inspiration, the negative intrathoracic pressure causes increased blood return into the right side of the heart.
|
| 6. | The negative intrathoracic pressure may cause the left atrium to expand and stretch its walls during each OSA event.
|
| 7. | They also significantly increase negative intrathoracic pressures that can harm internal structures and potentially impair post-operative recovery.
|
| 8. | "' Tracheal deviation "'is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.
|
| 9. | So if the vein gets cut, it cannot close and air is sucked in due to negative intrathoracic pressure causes air embolism.
|
| 10. | This retardation of the blood also occurs in lung lesions, such as chronic interstitial pneumonia, pleural effusions, and intrathoracic tumors.
