The difference between diagnoses and monitoring patients: | ATS- American Thoracic Society= -+5% Accuracy monitoring devices versus -+3% for diagnostic spiratory. |
ATS- American Thoracic Society= -+5% Accuracy monitoring devices versus -+3% for diagnostic spiratory. | Neuromuscular disorders & pulmonary strengths |
Reasons for weaning: | • Weaning from mechanical ventilation • Assessing the need for mechanical ventilation • Extubation especially in the PACU • Evaluation of neuromuscular disease progression • Evaluation of flows in asthmatics pt (peak flow meters) |
Three types of Spirometer: | 1. Wright Spirometer 2. NIF- inspiratory pressure 3. PEFR –Peak Expiratory Flow Rate |
Proper technique when using the SVC Wright Spirometer | 1. Zero the device 2. Use filter to protect from contamination 3. For accurate Vt measure the VE and divide by the respiratory rate Repeat 3x |
Normal Values for Wright Spiratory | Vt 7-9 ml of ideal body weight, VE 5-10 L/M, SVC 15-50 ml/kg of IBW |
Proper Technique when using the NIF | 1. Block/occlude the airway for 20 seconds 2. Three attempts unless the 1st was off scale 3. Report the higher of all 3 attempts |
What are the Predicted Values for NIF | -20 cwp (to start the weaning process), -90 cwp to -120 cwp |
What are two driving ways PEFR- Peak Expiratory Flow Rate- | Electrical and Mechanical |
Proper technique for PEFR: | Deep breathe in and blast out- recording in the first ½ second. Best of three. |
Normal Values for PEFR: | Vary but approx. 300-600 ml. (based on gender, ht, age) Look at sheet and normal should be between 80-120 of predicted value |
Bedside weaning procedures: | MIP- 20cwp Vt 5-7 ml/kg VE <30 breaths per minute VE < 10 lpm VC 10-15 ml/kg |
Two things that effect weaning: | 1. Strength 2. Demand |
True or false: A pt who can pull -15 cm H2O P on the P max test is ready to wean? | False |
Tidal Volume= ______ divided by _____ | VE, RR |
To measure diaphragm strength you would do a ? | MIP, NIP, MIF |
What are three ways to check the validity of the readings on a pulse oximeter | test youreslf, take a manual pulse, Look at the pulse indicatior light strip |
The device for bedside VC is called a? | Wright Respraometer |
A peak flow meter is usally used for pt with what? | asthma |
What is my average tidal volume if my VE is 6L and my RR 12 | 6000/12=500ml |
