Mountains form their own weather, with sudden showers emerging in some valleys while others remain dry or even sunny. Prepare for extremely variable weather.
A form of mechanical ventilation in which the peak inspiratory flow rate, fraction of inspired oxygen, positive end-expiratory pressure, respiratory rate, and tidal volume are preset and delivered to the patient.ressure support ventilation positive pressure ventilation in which the patient breathes spontaneously and breathing is augmented with air at a preset amount of pressure, with tidal volume not being fixed.
Pulmonary ventilation, or gas flow into and out of the lungs, relies on the pressure gra-dient between the atmosphere and alveoli, and airway diameter. Given that gas flow in a system is equal to the pressure gradient divided by the resistance, when resistance increases, gas flow decreases, and vice versa.
