Positive end-expiratory pressure (PEEP) is the pressure in the lungs (alveolar pressure) above atmospheric pressure (the pressure outside of the body) that exists at the end of expiration. [1] The two types of PEEP are extrinsic PEEP (PEEP applied by a ventilator) and intrinsic PEEP (PEEP caused by an incomplete exhalation).
Positive end-expiratory pressure will improve oxygenation. Drug administration via peripheral veins is preferred over endotracheal administration. Hypotension remaining after oxygenation may be treated by rapid crystalloid infusion. [34] Cardiac arrest in drowning usually presents as asystole or pulseless electrical activity.
Several factors inhibit HPV including increased cardiac output, hypocapnia, hypothermia, acidosis/alkalosis, increased pulmonary vascular resistance, inhaled anesthetics, calcium channel blockers, positive end-expiratory pressure (PEEP), high-frequency ventilation (HFV), isoproterenol, nitric oxide, and vasodilators.

The therapy is an alternative to positive end-expiratory pressure (PEEP). Both modalities stent open the alveoli in the lungs and thus recruit more of the lung surface area for ventilation. However, while PEEP refers to devices that impose positive pressure only at the end of the exhalation , CPAP devices apply continuous positive airway ...
Other signs of Lyme disease include fever, chills, headache, fatigue, and a bullseye-shaped rash. Diagnosis mainly takes two things into consideration: the presence of these symptoms and the ...
The Weeknd has opened up about suddenly losing his voice at a concert in 2022, saying he thinks stress and "self-imposed pressure" caused it.. The Canadian singer-songwriter, a.k.a. Abel Tesfaye ...
Firstly, as the air enters the lungs, it is humidified by the upper airway and thus the partial pressure of water vapour (47 mmHg) reduces the oxygen partial pressure to about 150 mmHg. The rest of the difference is due to the continual uptake of oxygen by the pulmonary capillaries , and the continual diffusion of CO 2 out of the capillaries ...
