Pulmonary Assessment Equipments: What are the types of electrodes? 1. Polargraphic 2. galvanic fuel cell
Pulmonary Assessment Equipments: what is a polargraphic? 1. It requires battery and a n electrolyte solution. 2. If analyzer don’t read 100% - then change battery. 3. If analyzer don’t read and battries are good - then change electrolyte solution. ex: clark electrode.
Pulmonary Assessment Equipments: What is a galvanic fuel cell? Its a cell batery & is good & common.If not working-it could be fuel cell is consumed so change cell.DON'T change solution/battery bcoz CELL is the battery.It is affected by high pressures changes in altitude, H20 on the electrode. PAP causes high reading
Pulmonary Resuscitation Equipments: Desired characterstics? 1. self-inflating. 2. NBR valve. 3. Adjustable relief valve on pediatric models, fixed 25cmH2O on adult models. 4. Internal diameter connector of 15mm,outer diameter22mm. 5.Reservoir to maximize FIO2. 6.Shapeable, transparent& inflatable mask.
Pulmonary Resuscitation Equipments: Troubleshooting If bag collapses easily when squeezed & no chest rise replace bag & If bag is difficult to squeeze, ensure pt. valve isnt stuck, check if the problem is low pulmonary compliance. If bag is suspected faulty replace bag dont fix the problem unless no option
Pulmonary Resuscitation Equipments: Mouth-to-valve mask 1. serves as a barrier b/w pt. and provider. 2. Cross contamination from pt.s expelled air is prevented through a one-way valve. 3. Superior to mouth-to-mouth ventilation.
Pulmonary Resuscitation Equipments: Demand valve (Pneumatically powered) 1. Deliever 100% FIO2. 2. Triggers by manual button & negative inspiratory pressure produced by the pt. 3. Not sensitive to changes in lung compliance-risks a pneumothorax. 4. Too powerful for infants. 5. Associated w/ gastric insufflation.
Suctioning Equipment: Suctioning Catheter- Closed system suction catheter 1. Ballard is an eg. For closed suction device. 2. allows repeated used of the catheter-bags keep catheter sterile. 2. No discontinuance of FIO2/mechanical ventilations. 3. Useful when pt. is on high PEEP levels (no break in PEEP).
Suctioning Equipment: Suctioning Catheter- Standard Catheter 1. Must maintain sterile technique when using. 2. one-time use only. (no cleaning)
Suctioning Equipment: Suctioning Catheter- Coude Tip Catheter 1. Tip of catheter is bent slightly to facilitate entrance and suction of the left mainstem bronchous. 2. Can be twisted to direct into either bronchus. 3. requires sterile technique.
Suctioning Equipment: Catheter Size- Length 1. Nasal/Oral suctioning- 20 inches. 2. Tracheostomy suctioning- 15 inches.
Suctioning Equipment: Catheter Size- Diameter 1. should not exceed 1/2 of the internal diameter of the ET/Trach tube.
Suctioning Equipment: Catheter Size- Diameter in French Units 1. 1mm/ID of ET/Trach tube = 3 French. Ex. If Id = 6.0 mm, catheter shouldnt exceed 3.0mm i.e. 3.0mm*3 = 9 French catheter. 2.If catheter comes in 8-10 french & catheter needs to be 9 (choose smaller of 2 (8 fr.) 3. 10 & 12 Fr.
