VT |
5-10mL/kg ideal body weight |
|
|
Pressure control |
Less than <35cmH2O |
|
|
RR |
10-20 |
|
|
FI02 INITIAL |
If patient is on room air or not prior information? 40-60% If pt is already on oxygen keep it at current level |
|
|
PEEP |
2-6cmH20 Or current CPAP pressure |
|
|
How to calculate Ideal Body Weight |
50kg + (2 * inches over 5 ft) Ex: Man 5'10" IBW 50 + (2 * 10) = 70 |
|
|
How to calculate alveolar minute ventilation |
(Tidal volume- Dead Space)*2 |
|
|
Normal compliance |
60-100 |
|
|
Static compliance calculation |
Exhaled volume —--------------------- Plat - PEEP |
|
|
Dynamic compliance |
Exhaled volume -‐------------------------- Peak-PEEP |
|
|
If Peak pressure are rising but the plat remains the same it..... |
An increase in Airway resistance |
|
|
If Peak pressure and plat pressure are both rising.... |
Pt has decreased compliance |
|
|
Calculate RAW |
PIP-Plat |
|
|
What causes an increase in Airway resistance two causes |
Secretions or bronchospasm |
|
|
What causes a decrease in lung compliance four causes |
Atelectasis pulmonary edema ards and PNA |
|
|
What is the mean airway pressure with patients with normal compliance and resistance |
5 to 10 |
|
|
Mean airway pressure with in patients with obstructive disease |
10 to 20 |
|
|
Mean airway pressure in patients with ards |
15-30 |
|
|
When weaning a patient how do you calculate where to put the pressure support |
By calculating Airway resistance pip - Plat Ex pip 30 - 20plat = PS 10 |
|
|
What are two reasons that you would switch to oscillation |
High inspiratory pressure greater than 50 and air leaks such as pneumothorax |
|
|
On an oscillator what is 1 Hertz is equal to |
60 cycles per minute |
|
|
When using an oscillator what do you change to control the CO2 |
The amplitude |
|
|
Adjusting the amplitude on an oscillator is similar to changing what setting |
The title volume |
|
|
What effect will lowering the frequency on an oscillator have on the abg's |
It will allow time for the patient to Exhale more CO2 |
|
|
Mean airway pressure controls what levels |
Oxygen |
|
|
If your patient is acidotic do you change the respiratory rate or tidal volume first |
Tidal volume |
|
|
When increasing fio2 on a ventilator how much do you turn up the |
In increments of 5% |
|
|
If oxygen is at 60% increase peep by increments of how much |
2-5 centimeters |
|
|
When lowering a high pao2 do you decrease the oxygen or the peep first and why |
Oxygen Because it's a drug use as little drugs as possible |
|
|
Wave graph looks like a football |
Mandatory breath |
|
|
How to fix Beaking |
Turn down the volume it is a sign of overdistention |
|
|
If the volume graph is lying down what do you need to adjust on the ventilator |
Increase the peep and it will stand up |
|
|
Any question that gives you the option to increase the flow |
always increase the flow |
