chapter 10 (mask and ventilation) Flashcards
the use of positive pressure to force air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing. Also called positive pressure ventilation.
artificial ventilation
a device, usually with a one-way valve, to aid in artificial ventilation. A rescuer breathes through the valve when the mask is placed over the patient’s face. It also acts as a barrier to prevent contact with a patient’s breath or body fluids. It can be used with supplemental oxygen when fitted with an oxygen inlet.
pocket face mask
a handheld device with a face mask and self-refilling bag that can be squeezed to provide artificial ventilations to a patient. It can deliver air from the atmosphere or oxygen from a supplemental oxygen supply system.
bag–valve mask (BVM)
a permanent surgical opening in the neck through which the patient breathes.
stoma
a device that provides positive pressure ventilations. It includes settings designed to adjust ventilation rate and volume, is portable, and is easily carried on an ambulance.
automatic transport ventilator (ATV)
a device connected to an oxygen cylinder to reduce cylinder pressure so it is safe for delivery of oxygen to a patient.
pressure regulator
a device connected to the flowmeter to add moisture to the dry oxygen coming from an oxygen cylinder.
humidifier
a face mask–and–reservoir bag device that delivers high concentrations of oxygen. The patient’s exhaled air escapes through a valve and is not rebreathed.
nonrebreather (NRB) mask
a device that delivers low concentrations of oxygen through two prongs that rest in the patient’s nostrils.
nasal cannula (NAY-zul KAN-yuh-luh)
a face mask–and–reservoir bag device that delivers specific concentrations of oxygen by mixing oxygen with inhaled air.
Venturi mask
a device designed to be placed over a stoma or tracheostomy tube to provide supplemental oxygen.
