Pulmonary function tests (PFTs) measure lung function and breathing issues.

PFTs measure lung volumes, capacities, diffusion, gas exchange, flow rates, airway resistance, and ventilation distribution.

Clients with breathing difficulties, suspected lung disease, or pre-surgical respiratory risk assessment.

Do not smoke 6-8 hours before a PFT.

Clients must not use inhalers 4-6 hours prior to PFT. Policy may vary.

A blood test that measures the oxygen and acid-base balance in the blood.

Measures the amount of free hydrogen ions (H+) in the blood, indicating acidity or alkalinity.

Measures the partial pressure of oxygen dissolved in the blood.

Measures the partial pressure of carbon dioxide dissolved in the blood.

Measures the concentration of bicarbonate in the blood, which helps regulate acid-base balance.

A blood test that measures the oxygen levels and acid-base balance in the blood, giving information about how well your lungs are working and how your body is managing acid levels.

A test that checks whether the ulnar artery is working properly, ensuring blood flow to the hand before an arterial puncture.

A syringe coated with heparin, a medication that prevents blood clotting, used to collect arterial blood gas samples.

The Allen's test ensures blood flow can bypass the artery to be punctured, preventing damage to the hand if there's a blockage in the radial artery.

A procedure to collect blood directly from an artery, usually the radial artery in the wrist, for analysis.

Collecting a blood sample directly from an artery, usually the radial artery, using surgical aseptic technique and a heparinized syringe.

After drawing ABG, immediately place the specimen in a basin of ice and water to preserve pH levels and oxygen pressure.

Accessing the radial artery for ABG sampling can be more difficult in older adults due to impaired peripheral vasculature.

ABG specimens must be transported to the laboratory immediately after collection.

Immediately after an arterial puncture, hold direct pressure over the site for at least 5 minutes, or 20 minutes if the client is on anticoagulants. Ensure bleeding stops before releasing pressure.

After an arterial puncture, monitor the site for any signs of bleeding, loss of pulse, swelling, temperature changes, or color changes.

Blood pH levels below 7.35 indicate acidosis, and levels above 7.45 indicate alkalosis.

After performing an arterial puncture, document all interventions performed and the client's response to the procedure.

Report ABG results to the provider as soon as they are available.

A hematoma is a collection of blood that builds up under the skin, usually at the site of a puncture.

The Trendelenburg position, where the head is lower than the feet, helps to push any air bubbles in the arterial system towards the heart, which is a stronger pump.

The Valsalva maneuver involves bearing down while holding your breath. This increases pressure in the chest and helps to push air bubbles out of the arteries.

Some common signs of an air embolism include sudden shortness of breath, decreased oxygen levels, chest pain, anxiety, and feeling like you can't get enough air.

If an air embolism is suspected, the most important actions are placing the patient in Trendelenburg, asking them to do the Valsalva maneuver, and monitoring for any worsening breathing difficulties.

A procedure that uses a flexible or rigid scope to visualize the larynx, trachea, and bronchi. It's like looking into the airway with a tiny camera.

It helps diagnose and treat airway problems. This includes things like finding tumors, taking biopsies, removing foreign objects, and even treating lung collapse.

There's a chance of bleeding or a puncture in the airway, especially if a biopsy is done.

We can insert the scope through the endotracheal tube to visualize the airway of a client on a ventilator.

It provides valuable information about the airway, allowing doctors to diagnose and treat problems more effectively.
