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=500m
