Should a ventilator be adjusted to maximize the volume of air inhaled and exhaled Explain?
The Ventilator should be adjusted to OPTIMIZE volume, not maximize. You optimize volume using objective data such as Pressure/Volume loops to look for overdistention "duck-billing", and volumes should be set initially based on ideal body weight. According to ARDSnet protocol weight should be based on- Males- 50+2.3(height in inches-60) and females- 45.5+2.3(height in inches-60), initially giving 8ml/kg working down to 4-5ml/kg if necessary.
Is absolute pressure static pressure?
absolute pressure
How do you calculate suction pressure for air theoretically?
Air has a pressure, but not a suction pressure. Air pressure is measured with a barometer, you do not calculate it. Suction pressure is a concept which applies to a pump. Suction pressure = static pressure + surface pressure - vapour pressure - friction pressure.
Does it move from an area of high pressure to low pressure or low pressure to high pressure?
A fluid will move from high pressure to low pressure.
What is the force exerted on surface divided by the area over whech the force is exerted?
That's the pressure on that particular area.
When was Negative pressure ventilator created?
Negative pressure ventilator was created in 1928.
The peak pressure on a ventilator reads 40 cm h20what is the equivalent pressure in mm hg?
the peak pressure on a ventilator reads 40 cm h20 what is the equivalent pressure in mm hg?
What are the 2 types of sensitivity in a mechanical ventilator?
A mechanical breath delivered by the ventilator can be initiated either through a detected change in the flow in the circuit, or a detected negative pressure (so flow trigger or pressure trigger)
What are the strategies to improve oxygenation?
The open lung approach is based on pressure-targeted ventilator strategies.
What in peak inspiratory pressure?
The maximum pressure exerted against the patients airway during the breath.
What is normal ventilator plateau pressure?
The plateau pressure is the pressure applied (in positive pressure ventilation) to the small airways and alveoli. It is believed that control of the plateau pressure is important, as excessive stretch of alveoli has been implicated as the cause of ventilator induced lung injury. The peak pressure is the pressure measured by the ventilator in the major airways, and it strongly reflects airways resistance. For example, in acute severe asthma, there is a large gradient between the peak pressure (high) and the plateau pressure (normal). In pressure controlled ventilation, the pressure limit is (usually) the plateau pressure due to the dispersion of gas in inspiration. In volume control, the pressure measured (the PAW) by the ventilator is the peak airway pressure, which is really the pressure at the level of the major airways. To know the real airway pressure, the plateau pressure which is applied at alveolar level, the volume breath must be made to simulate a pressure breath. An inspiratory hold (0.5 to 1 second) is applied, and the airway pressure, from the initial peak, drops down to a plateau. The hold represents a position of no flow.
How positive pressure ventilation effect fi02?
positive pressue ventilation is usually provided by a mechanical ventilator. A blend of oxygen and air coming out of the ventilator. The FiO2 is set on the ventilator. The person gets the FiO2 set on the ventilator.The manual positive pressure ventilation is by resuscitating with a self inflating bag usually provided with oxygen. FiO2 is fractional inspired oxygen and does not change with positive pressure ventilation or negative pressure ventilation. Manual bagging FiO2 may be changing according to supply of oxygen, inhalation (speed and volume) and frequency of bagging.
When was Ventilator Blues created?
Ventilator Blues was created on 1972-05-12.
Can heated humidity be provided for both stationary ventilator and when the ventilator is in transport?
yes
What are the errors that can happen in a medical ventilator?
There are many different errors that can happen in a medical ventilator. The medical ventilator could just freeze up and stop working for example.
What is the use of ventilator?
The ventilator is used to calm down the breathing and the airways to the lungs. It also calms down massive coughing fits.
How does the heat recovery ventilator works?
The heat recover ventilator works by cooling and dehumidifying the air around you. The ventilator sends fresh air from outside and emits it indoors, heated.
