Why the slope of temperature versus pressure graph is positive in some cases and negative in other cases?
If the pressure is increasing then the slope is positive. If the pressure is decreasing then the slope is negative.

What is indicated by a negative lfft value?
A negative Left Ventricular Filling Pressure (LVFP) value, often referred to as a negative left atrial filling pressure, suggests that there is a reduced pressure in the left atrium, potentially indicating impaired diastolic filling of the left ventricle. This can occur in conditions such as hypovolemia or certain forms of heart failure. A negative value may also imply that the heart is unable to effectively fill due to decreased volume or compliance. It's crucial to interpret this value in the context of the patient's overall clinical picture.
If a process is carried out at constant pressure P and the volume V of the system decreases then V is negative positive and the work w is negative positive zero?
In this case, V would be negative, and work w would be positive.
What is intrathoracic pressure?
Intrathoracic pressure is the pressure inside of the pleural cavity. It is also called intrapleural pressure and the normal pressure is called negative pressure.
What is the intrathoracic pressure?
Negative intrathoracic pressure is the normal pressure in the area between the pleura of the lungs and the chest wall. The pressure is considered negative because it is less than the atmospheric pressure.
Does negative intrathoracic increases with inspiration?
Yes.
What happens when relaxation of the diaphragm and intercostal muscles increases intrapulmonic and intrathoracic pressure?
Exhalation describes the state when the diaphragm relaxes and intrapulmonic and intrathoracic pressure increases.
What pressure keeps lungs inflated?
Intrathoracic pressure
Intrathoracic pressure definition?
Intrathoracic pressure refers to the pressure inside the chest cavity, including the lungs and surrounding tissues. It plays a crucial role in breathing by helping to expand and contract the lungs during respiration. Changes in intrathoracic pressure can impact lung function and overall respiratory health.
Why pause between inspiration and expiration in bronchial breathing?
inspiration is an active process that takes place by creation of negative intrathoracic pressure, in normal states where breathing is vesicular, even at a low negative pressure air keep on flowing into alveoli but in bronchial breathing as alveoli are either filled with secretions as in consolidation or a cavity is already filled with air and other contents, no movement of air takes place at the end inspiration despite of negative intrathoracic pressure thereby causing a pause between inspiration and expiration- now pay me thousand dollar!
What is the effect of respiration on the heart sounds?
during inspiration, intrathoracic pressure is decreased.
Why intrathoracic decreases during inspiration?
During inspiration, the diaphragm contracts, moving downward, and the external intercostal muscles contract, moving the ribcage upward and outward. These actions increase the thoracic volume, causing the intrathoracic pressure to decrease. This decrease in pressure creates a pressure gradient that allows air to flow into the lungs.
How does positive pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
How does positive-pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
What is an intrathoracic node?
An intrathoracic node is a node within the chest cavity.
