Clinical Skills
The hands-on competencies that define bedside respiratory care — drawing the gas, reading the monitors, clearing the airway, expanding the lungs, and doing it all without spreading infection. Step-by-step technique, the values that flag trouble, and the device comparisons behind each skill.
Guides
Step-by-step technique for the core bedside procedures.
Arterial Blood Gas Sampling
How to obtain an arterial blood gas sample — site selection, the modified Allen test, technique, and the pre-analytic errors that ruin a result.
Pulse Oximetry & Co-oximetry
How pulse oximetry works and where it fails — the two-wavelength principle, accuracy limits, and why carbon monoxide and methemoglobin demand co-oximetry.
Chest Physiotherapy & Airway Clearance
Chest physiotherapy and airway clearance techniques — postural drainage, percussion, PEP, oscillatory devices, and HFCWO — with indications and key contraindications.
Incentive Spirometry & Lung Expansion Therapy
Incentive spirometry and lung expansion therapy for atelectasis — correct sustained-maximal-inspiration technique, indications, and when to use IPPB or CPAP instead.
Manual Resuscitation with a Bag-Valve-Mask
Manual resuscitation with a bag-valve-mask — bag types, mask seal, oxygen delivery, rate and volume, and avoiding the harm of over-ventilation.
Tracheostomy Care
Routine and emergency tracheostomy care — inner cannula and stoma care, cuff pressure, humidification, securing the tube, and the decannulation emergency.
Humidity & Bland Aerosol Therapy
Humidity and bland aerosol therapy — humidifiers versus aerosol generators, when a bypassed airway must be humidified, and the bronchospasm risk of hypertonic saline.
Bedside Respiratory Measurements
Bedside respiratory measurements that guide weaning — vital capacity, MIP/NIF, MEP, minute ventilation, and the rapid shallow breathing index, with their thresholds.
Sputum Induction & Specimen Collection
Sputum induction and specimen collection — expectorated versus induced samples, hypertonic-saline technique, specimen quality, and airborne precautions for suspected TB.
Infection Prevention in Respiratory Care
Infection prevention in respiratory care — hand hygiene, transmission-based precautions, aerosol-generating procedures, equipment processing, and the VAP bundle.
Equipment Reprocessing & Disinfection
How respiratory care equipment is reprocessed — the Spaulding classification, the cleaning-disinfection-sterilization hierarchy, and the specific agents and methods (glutaraldehyde, OPA, ethylene oxide, autoclave, pasteurization) used to make reusable devices safe between patients.
Respiratory Care Safety: Fire, Electrical & Cylinder Hazards
The safety hazards unique to respiratory care and how to control them — the oxygen-enriched fire triangle and the RACE and PASS responses, electrical macroshock versus microshock and leakage current, and safe compressed-gas cylinder handling and storage.
Interactive Practice
Practice Tools
Two bedside measurements you compute by hand — the rapid shallow breathing index and minute ventilation — central to weaning and respiratory assessment.
Clinical References
Positions, thresholds, sites, and tube sizes you look up at the bedside.
Postural Drainage Positions
Postural drainage positions by bronchopulmonary segment, with the head-down contraindications and how long to hold each position.
Bedside Pulmonary Measurements & Weaning Thresholds
Bedside pulmonary measurements and the weaning thresholds for vital capacity, MIP/NIF, MEP, respiratory rate, minute ventilation, and RSBI.
Tracheostomy Tube Types & Sizing
Tracheostomy tube types and sizing — cuffed, uncuffed, fenestrated, and dual-cannula tubes, plus the speaking-valve cuff-deflation safety rule.
ABG Sampling Sites & the Allen Test
Arterial blood gas sampling sites compared and the step-by-step modified Allen test for confirming collateral circulation before a radial puncture.
Medical Gas Cylinders & Regulators
A bedside reference to compressed medical gas hardware — cylinder color codes, service pressures, the cylinder-factor duration calculation, the PISS and DISS safety connection systems, and single- versus multi-stage reducing valves and regulators.
Equipment QC & Calibration
A reference to respiratory equipment quality control and calibration — blood gas analyzer QC with Levey-Jennings charts and the Westgard multi-rules, two-point calibration, oxygen-analyzer calibration at 21 percent and 100 percent, and spirometer, ventilator, and monitor performance verification.
Quick Charts
Side-by-side comparisons behind each clinical decision.
Airway Clearance Techniques Compared
A side-by-side comparison of airway clearance techniques — conventional CPT, directed cough, PEP, oscillatory PEP, HFCWO, IPV, and cough assist — with indications and precautions.
Lung Expansion Therapies Compared
A side-by-side comparison of lung expansion therapies — incentive spirometry, deep breathing, IPPB, CPAP, and PEP — by mechanism, patient requirement, and best use.
Isolation Precautions Compared
A side-by-side comparison of standard, contact, droplet, and airborne isolation precautions — when each applies, the PPE required, room type, and examples.
Humidity & Aerosol Devices Compared
A side-by-side comparison of humidity and aerosol devices — bubble and heated humidifiers, HME, large-volume and ultrasonic nebulizers, and heated high-flow — by output and use.
Flowmeters, Blenders & Oxygen Analyzers
A side-by-side comparison of respiratory gas-control and analysis hardware — pressure-compensated versus uncompensated Thorpe-tube flowmeters, the Bourdon gauge, air-oxygen blenders, and galvanic (fuel cell) versus polarographic (Clark) oxygen analyzers — including each device's operating principle, key advantage, and back-pressure error mode.
