|
|
Name the 4 Main Clinical Manifestations of Acute ResF regarding
1. O2/CO2 2. Breath 3. Energy 4. CNS/Heart |
1. Prob maintain adequate 02 or appropriate CO2
2. Dyspnea or Tachypnea 3. Progressive Fatique, +/- -->resp arrest 4. Neuro fxn deterioration and Myo Ichemia or infarction |

|
CXR findings for Acute ResF
|
Normal/relatively
Localized alveolar filling opacities Diffused alveolar filling opacities |
|
|
Indications for Intubation
|
Inability to Ventilate (sedation/fatigue/trauma)
inability to Oxygenate Excessive work of breathing Protection of the airways Hyperventialtion |
|
|
Regarding ventilation
What is the FIO2? VE? |
FIO2 is Inspired 02 concentration
VE is Minute Ventilation (total volume of air breathed during 1 min) |
|
|
Distinguish between these 3 ventilation terms:
1. Inspiratory P. 2. Trigger P. 3. PEEP |
1. Inspiratory P.-- P. supplied by machine
2. Trigger P. --neg. pres a Pt must achieve ot initiate a ventilator supported breath 3. PEEP--Positie End Expiratory Pres. : Pres machine maintaines during expiration to keep ducts patent |
|
|
What is a sigh
|
