## Abstract

Tension pneumothorax inserts for patient simulators, as well as associated devices, systems, and methods, are provided. A tension pneumothorax insert may comprise: a body defining a chamber, wherein the chamber can be pressurized through introduction of air into the chamber; and a skin layer coupled to the body and positioned over the chamber, wherein the skin layer and the chamber are configured to simulate a natural tension pneumothorax such that an audible hiss is emitted by release of air from the chamber when a needle is inserted through the skin layer and into the chamber.

## Claims

### Claim 1

A tension pneumothorax insert for a patient simulator, the insert comprising:
a body defining a chamber, wherein the chamber can be pressurized through introduction of air into the chamber; and
a skin layer coupled to the body and positioned over the chamber, wherein the skin layer and the chamber are configured to simulate a natural tension pneumothorax such that an audible hiss is emitted by release of air from the chamber when a needle is inserted through the skin layer and into the chamber.

### Claim 2 (depends on 1)

The insert of claim 1, further comprising at least one rib coupled to the skin layer.

### Claim 3 (depends on 2)

The insert of claim 2, wherein the at least one rib comprises a plurality of ribs.

### Claim 4 (depends on 3)

The insert of claim 3, wherein the plurality of ribs define a simulated second intercostal space.

### Claim 5 (depends on 1)

The insert of claim 1, further comprising a port in communication with the chamber.

### Claim 6 (depends on 5)

The insert of claim 5, wherein the port is configured to interface with a pump.

### Claim 7 (depends on 6)

The insert of claim 6, wherein the pump is external to the patient simulator.

### Claim 8 (depends on 7)

The insert of claim 7, wherein the pump includes a squeeze bulb pump.

### Claim 9 (depends on 6)

The insert of claim 6, wherein the pump is internal to the patient simulator.

### Claim 10 (depends on 9)

The insert of claim 9, wherein the pump is electronically controlled.

### Claim 11

A patient simulator, comprising:
a simulated torso, the simulated torso including a simulated tension pneumothorax comprising:
a body defining a chamber, wherein the chamber can be pressurized through introduction of air into the chamber; and
a skin layer coupled to the body and positioned over the chamber, wherein the skin layer and the chamber are configured to simulate a natural tension pneumothorax such that an audible hiss is emitted by release of air from the chamber when a needle is inserted through the skin layer and into the chamber.
